DMSO dimethyl sulfoxide – the most important information in a nutshell:

DMSO – dimethyl sulfoxide information, use and dosage
Here I am writing about the use and dosage of DMSO. You will also learn something about this simple natural substance and its positive effects on the body of humans and animals.

What is DMSO?

DMSO is a substance that has many useful properties. Because of its regenerating, uplifting, strengthening and nourishing properties, I also call it “liquid love”. DMSO is made from tree bark.
Here I am showing you variants for DMSO that I know for internal and external use. These mostly come from personal experience and the collection of information on the topic.

Experience with DMSO – dimethyl sulfoxide

A compilation of experiences and reports.
Here are the most important properties of DMSO in brief:
DMSO is anti-inflammatory, decongestant, vasodilator, regenerative and effective in binding toxic radicals!

DMSO also serves as a carrier substance for medicines applied to the skin, such as ointments, gels and tinctures. It is also very suitable for introducing active ingredients such as sodium bicarbonate / procaine, vitamin B12 and ascorbate. So DMSO is a so-called penetration enhancer. One could also say “potentiator”.

Fear of DMSO

Some people are literally afraid that DMSO could “enter” something that is harmful and therefore prefer not to use it at all. Substances dissolved in DMSO are generally absorbed quickly and easily by the organism, including through the skin. But that also applies to contact poisons. But only if they are small enough for it. If one fortifies allopathic drugs directly with DMSO, which generally have side effects, DMSO thus also increases the side effects. So I would probably think about what to strengthen with DMSO. I would certainly not use it to reinforce conventional medical drugs.

However, DMSO does not infiltrate anything and everything !
The DMSO molecule is relatively small and can only introduce or smuggle in substances that are not much larger than itself. For example, bacteria does not bring DMSO into cells through the skin. However, the smallest molecules that are present on the skin could be smuggled in by DMSO. Whether this then leads to a disadvantage, of course, depends on the individual case and what you are talking about. Therefore, it should generally only be used on “clean” skin. I mean clean of molecules that shouldn’t be introduced. Therefore, I wash the areas where I want to use it on the skin beforehand with CDH3000 or a diluted MMS solution and let it soak in for a moment. Then I spray or brush the DMSO on. Most of the time, however, I just apply it with my fingers and distribute it. For the skin I generally use a dilution of 70%. This may itch a little after use. That is certainly a question of skin type. If this DMSO70% is too strong because I react too sensitively, I use DMSO50%.

From my own experience I can report that I was never very careful about the purity of the skin before use. But I have never experienced any negative effects from it.

DMSO application on the skin

However, there are some people who have overloaded their skin with deodorant or other fragrances or strong-smelling shower gels to such an extent that there may be unwanted substances there that I would not allow to enter. This can be the case, for example, with detergent residues that get from clothing onto the skin and could then be carried over with the DMSO.

To see the amount of detergent in the laundry, I tried the following once. I took a fresh t-shirt out of the closet and dipped it in a red bowl of pure water. Then I wrung it out in there. Now I could clearly see the whitish detergent residue in the bowl. And I already use an extra rinse program with more water and don’t use a lot of detergent anyway.

With some people I can literally smell as I walk past that they apparently have a chemistry in or on their body. Sometimes it smells so strong, as if I were walking past a perfumery. I have been able to perceive this extreme odor more often in women. With such a strong smell, I would also be a little worried that too much small-scale chemistry could be introduced by DMSO.

I only wash myself with natural substances, such as potash soap with a borax and citronella scent. Sometimes I wash smelly parts of the body with just pure CDH3000, which I simply put on a damp washcloth. By applying it to the damp washcloth, which already contains water, I have a solution of approx. 1500 ppm. After that, I am sure that nothing will be entered that I do not want. Then I apply DMSO or DMKB (which is a mixture of DMSO with magnesium, potassium and borax) without worrying.

DMSO neutralizes cell-damaging free radicals:

It makes these chemical compounds that are then excreted by the kidneys.
DMSO increases the permeability of cell membranes and thus makes it easier for cells to free themselves from ballast. DMSO even alleviates allergic reactions. The rubbish collection of our body is relieved.

DMSO and worldwide studies

There are approx. 11,000 studies worldwide on DMSO and it will certainly be further investigated. Will be used in well over 40,000 articles above the positive effects of DMSO reported.

Positive effects of DMSO

The following positive effects were observed on the following clinical pictures.
Arthritis and rheumatoid arthritis,
Arthrosis,
ADHD,
Acne,
Allergies,
age-related macular degeneration,
Angina pectoris,
Eye diseases,
Disc problems,
Burnout,
Ulcerative colitis,
Inflammation and pain,
Eczema (allergic),

Herpes,
interstitial cystitis,
Cancer,
Contact dermatitis,
Leprosy,

and many more. This is actually no wonder, given the range of effects that DMSO has.

DMSO and its properties at a glance

Here is a brief description of the pharmacological properties of DMSO:
DMSO penetrates biological Membranes .
DMSO transported other Molecules through the cell membranes.
DMSO does Cell membranes again functioning , passes through it indirectly nutrient one and releases poisons (Toxins) back out of the cells out .
DMSO works anti-inflammatory .
DMSO works anticoagulant .
DMSO modulated the Blood lipids .
DMSO blocked temporarily pain-conducting nerves .
DMSO inhibits the Growth of bacteria .
DMSO drains vessels (has a diuretic effect).
DMSO reinforced the Effects certain drugs and substances. As a result, these can then be dosed much less or even discontinued.
DMSO promotes the Resistance to Infection .
DMSO promotes the concentration .
DMSO works reassuring .
DMSO expanded the Blood vessels .
DMSO relaxed and loosens the muscles (inside and out)
DMSO strengthens the functions of the Cells .
DMSO inhibits the Clumping of blood platelets . So you might not need any more anticoagulants :-). Whether you really need them at all is another topic. Usually these are prescribed “as a precaution”.
DMSO protects biological tissues in front / at Irradiation or frost !
DMSO protects tissue at Circulatory disorders .
DMSO has antioxidant e properties.
DMSO acts as a Radical scavengers in the center of an inflammation.

The anti-inflammatory effect is also created by externally applied DMSO on joints . Also at Contact dermatitis , allergic eczema and Tissue calcification works DMSO.

In addition, DMSO the following effects:
DMSO causes a Stunted growth across from Bacteria, fungi and “viruses” .
DMSO eliminated Painful conditions .
DMSO counteracts Anemia .
DMSO stimulates that immune system at.
DMSO promotes the Wound healing .

Using an 80% concentration even “inactivated” some viruses, if they can be active at all. These include supposed RNA “viruses”: Influenza A, Influenza A2, Newcastle Disease “Virus”, Semliki Forest “Virus”.
Since it until today no scientific evidence for the existence of Viruses there are, but disease courses that are attributed to “viruses”, I have put this in quotation marks. I found the information for this www.samueleckert.net .

With the new DMSO100 (internally) there is even more to it. According to observations, DMSO is even supposed to influence the resistance of bacteria to antibiotics for humans. Still, I think the use of antibiotics is extremely questionable.

DMSO and radiation protection

DMSO appears to protect itself from X-rays. According to studies, it even protects against the negative effects of solar radiation. Radiation protection could also refer to the dreaded 5G radio radiation. By the way, I use the DMSO70% instead of sunscreen.

DMSO and scars

Very good results have been reported in the treatment of scar tissue. It regresses. Even deep down into the skin. Swellings subside noticeably. The analgesic effect of DMSO is immediate, at least in the case of acute pain.
Furthermore, there were positive successes even with the so-called “bursitis” in the shoulder joint with severe pain. After rubbing in the shoulders, I was told that there is often a strong improvement or even freedom from pain after just 20 minutes.
Pathological calcium deposits in the shoulder joint should also be able to be resolved with DMSO. For this, however, I would use it externally and internally.

How safe is DMSO?

According to the LD-50 value, DMSO is 7 times safer than the famous headache pill. The only “undesirable effect” observed so far is a garlic-like or difficult to define odor. Temporary skin irritation sometimes occurs at high concentrations. In the case of skin irritation (including severe itching), I dilute the solution with water until it disappears. I do this even if the DMSO has already been applied. I then simply wet the skin with some additional water. Reddened skin, itching, indigestion, nausea, vomiting, diarrhea, constipation and poor appetite are said to have occurred. Obviously, if the dose was too high at the beginning of use.

DMSO and the smell:

At over 37 ° C, DMSO produces an odor similar to that of garlic. Presumably it is the sulfur content. Other people sometimes smell this, especially if the user has taken a lot of DMSO internally. However, if you also take DMSO, you will no longer perceive this smell in the other person who is also taking it. In fact, it’s exactly the same as with garlic.

So the odor cannot be completely prevented. The more DMSO I take and the more the body needs cleaning, the stronger the smell. According to Hartmut Fischer , whose DMSO manual I always like to recommend that this smell should be reduced as the disease progresses and as your health improves.
Another possibility, besides only external use, is to take 2-3 drops with 1 ml of water in the mouth. I leave this solution there so that it is absorbed directly through the oral mucosa and the vena cava. As a result, there is hardly any odor, because the amount is simply smaller. Perhaps an odor can then be perceived within a radius of 5-10 centimeters. But that is the natural distance that you usually keep to other people anyway.

How does DMSO smell?

Some people describe the vapors as a smell of seaweed, oysters or crabs or even garlic.
Absorbed through the skin (percutaneously), the highest concentration in the blood serum is reached after four to eight hours, describes Fischer. Usually after about 4 hours orally. With small-area external applications, I hardly get a smell that others perceive.
If there is a sour smell, this could be due to an upcoming deacidification of the body. The stomach can regenerate and dispose of some bad smelling substances.

DMSO application

DMSO could be used like this:

  • applied externally (brush, drip or spray)
  • oral intake
  • Syringes, infusions
  • DMSO eye drops

I use a pipette to measure drops. For measurements in milliliters, a syringe (without cannula).

Dr. PA Hartmut Fischer has a tip on DMSO and disposable syringes

You should not measure DMSO directly with a freshly unpacked disposable syringe. Plasticizers and other soluble components in the syringe could dissolve in it.

So I would do better like this:

  1. Draw up a small amount of DMSO into the syringe.
  2. Swing the DMSO around in it.
  3. Then dispose of the DMSO and repeat the process again.

After this cleaning, the inner plastic surface no longer releases any significant amounts of substance.

How can it be checked?

With the freshly unpacked syringe you can literally see how “streaks” form when you draw DMSO100 into the syringe for the first time. This can no longer be observed after cleaning.

DMSO on the skin:

Vigorous rubbing in or even massaging is not necessarily recommended due to the possible skin irritation. Especially not when the concentration of DMSO is higher. So it’s better to just spray or gently rub / wet with your finger.

Dosing DMSO

I use a syringe (without cannula) or a sprayer for dosing and application. Metal spoons can be used, but some of them could release substances depending on their concentration and nature. I have been told of a metallic taste in this regard when taking DMSO with a spoon. Not all types of plastic are suitable for plastic spoons. I think the best method is to drip it directly into a glass or even on the skin. So I don’t use spoons.

DMSO and stains

DMSO is a solvent. Therefore, I am careful with the small splashes that can occur during use. This mainly refers to the 99-100% variant. These can “soften” PET and stain Plastics and metal surfaces cause. Incidentally, open wooden surfaces have no problem with DMSO. Apparently it even cares.

DMSO dosage

  1. Impact assessment:
    Before use, I apply a drop to the skin, distribute it and wait 20 minutes. If everything is okay, I can concentrate on using it. Internally I take 4 drops (approx. 0.18 ml.) In 10 ml of water and wait 20 minutes after taking them. If nothing unusual or unpleasant occurs, I continue. However, I have already drank DMSO 70% in higher doses. Approx. 6 ml for a glass of water. I use such a high dosage when I feel unwell and my heart is overloaded. Then I rested until I was fine.

DMSO external use


Apply DMSO

I apply DMSO 70% on the outside and spread it over a large area, but do not rub it. Punctual rubbings are spreading anyway. Above the belt line, I first use a dilution of 50 – 70 %. Below I can even tolerate 100%. If it itches or turns red, I dilute it with plain water. With a sprayer, which I fill with a 70% DMSO solution, I can also wet the skin surfaces very well. Especially on the back. I can even spray it myself with a sprayer and take care of it. In all cases, I first spray or wet existing, old scars. Because precisely these can cause energetic as well as structural disturbances. This also includes “vaccination scars”, i.e. the puncture points that are often still visible. DMSO is also externally an “anti-aging agent”.
I am often asked how to mix a DMSO ointment. This is not only very time-consuming, it is almost impossible. DMSO does not want to connect with anything solid and “always wants to get out”. DMSO is generally absorbed very well on its own. Therefore, I would not mix or even buy an ointment. It’s just expensive and doesn’t help, except for possible additives that I don’t even want to have.

Oral DMSO

A drop of DMSO100 from a pipette is approx. 0.05 grams. With such a pipette for the 100 ml amber glass bottle, I can measure the drops well and take them in water. Or in juice. However, the existing dropper is often enough for small bottles.

Version 1:
Take DMSO internally

I like to consume DMSO mixed in juice.

1.) I start with (approx. 0.3 ml. = 6-7 drops from a pipette) once a day and then increase to 3 times a day.

2.) Finally, I increase to 22 drops (approx. 1.0 ml) 3 times a day. If success allows, I then take a break at the weekend.

3.) The basic rule amount is 0.1 grams per kg of body weight. But the experiments on inmates carried out by Dr. Morton Walter, had shown that you can gradually increase to an amount of 1 g per kg of body weight. DMSO weighs 1.1 grams per milliliter. With a body weight of 77 kg, you could therefore (slowly increasing) ingest up to 70 ml per day. Of course, I would not take this immediately, but slowly increase from 0.1 grams. The question is also whether I really need this amount. With some problems this might help more quickly and may even be necessary. In variant 5 I wrote something about it.

Variant 2:

DMSO enhances the effectiveness of CDH3000 (CDL) or “MMS”
Another variant is to take DMSO as an active enhancer for other substances, such as MMS or the MMS ready-to-use mixture CDH3000. For this I use DMSO in twice the number of drops as the activated MMS.
With a daily amount of 24 drops of activated MMS, that would be a total of 48 drops of DMSO per day.
Since I take the MMS 8 times a day in single doses, every time I take MMS (mixture of 3 drops of sodium chlorite 25% with 2 drops of hydrochloric acid 4% (chlorine dioxide set) in at least 125 ml of water or juice, there is a quantity of 6 drops of DMSO100 per single dose. If I prefer to use the CDH3000 solution instead of MMS, I add 6 drops of DMSO to 3 ml of CDH3000, which I mix in 125 ml of water. The amount of DMSO remains the same here. Of course I can also use more DMSO. I mix the DMSO into the finished solution just before taking it.

By the way: Many users report that the taste of MMS or CDH3000 is more pleasant when adding DMSO. If in addition to that, I also MKB Vital in the same amount as using DMSO, the taste and also the effect are even better and stronger. MKB Vital is a mixture of magnesium, potassium and borax. Anyone who has already dealt with the topic of borax and magnesium knows why this combination has to be ideal. Magnesium enhances the effects of borax, so I need a lot less borax than if I were taking this alone. There is also this ready-made mix of DMSO, Magnesium, Potassium, and Borax. It is called “DMKB”. With chronic problems I take 1: 3 to CDH. For example 3 ml CDH3000 with 1 ml DMKB and at least 4 ml water. It is even more pleasant to drink the mixture in a glass of juice. You can read more about the products I use in the section on the different products I use here.

Variation 3:
Brushing your teeth with DMSO, CDH / MMS and MKB Vital:
I use 3 ml CDH3000 + 3 drops DMSO100 and 3 drops of MKB Vital + 3 ml of water. I inject this solution into my mouth. For this I like to use the Doser, which you can order when buying the CDH3000. Then I use it to rinse my mouth for up to 1 minute and finally use it to brush my teeth with a toothbrush. The solution should of course not run out. After the process, I can either swallow it or spit it out.

Variation 4:
DMSO for a clear head:
I drip 1-2 drops straight into my mouth and salivate it for 2-3 minutes. Then I can swallow it. Usually the head becomes very clear shortly afterwards, as it comes in via the oral mucosa directly via the vena cava.

DMSO gum problems

With wobbly teeth due to gum problems, I can rub it directly on the affected gums with my finger. When using DMSO100, I usually notice an effect immediately, as it goes through the oral mucosa into the blood. DMSO70% can also be used for this. The bowel apparently shows shortly thereafter that it is relaxing and the subsequent stools obviously detoxify the bowel afterwards.

Variation 5:

Flood the body with DMSO:

The “flooding”: In the case of severe problems, I drink a total of 1 gram per kg of body weight mixed in pure water or juice. For example, if I have a body weight of 77 kg, it would be 70 milliliters that I could take a maximum of several times a day. Jim Humble called this variant as an immediate measure for an acute stroke or heart attack. With such a crowd, of course, a lot is in motion. Therefore, I would always allow myself time to rest afterwards.

Otherwise I would approach this amount with a slow increase of 4 ml daily.
So on the first day 4 ml, the next day 8 ml and so on.
But if there is an overload of the organism, I naturally reduce the amount. Therefore, I would basically increase slowly. The taste of DMSO is sweet and a little bitter. If I no longer like the large amounts and feel uncomfortable, I only mix it with the amount of juice that I need to make it taste pleasant. With the flooding, however, it should be noted that the smell for the environment and people in the area can be extreme. You don’t have many friends anymore ;-).

Variation 6:

DMSO for larynx problems

DMSO 70% Squirt from the bottle onto the larynx or the tonsils and let it work there. Let any residues in the throat area slowly run past it. In addition, I applied it externally around the neck. I always slowly test myself against the crowd. If I’m fine, I can continue to improve.
If I am not doing so well (headache or diarrhea with undigested food residues) I lower the amount.

There are many possible combinations with DMSO.
The DMSO100 tastes sweet / bitter undiluted. When mixed with water, it becomes increasingly bitter and less sweet. So I mix it in a way that is comfortable to drink. If necessary, I rinse again with some juice or water or drink it in juice right away.
However, I do not exceed the maximum total amount of 1 g per kilogram of body weight per day.

In animals, 0.5g per kilogram of body weight should not be exceeded.
However, this limit is only a fictional theoretical one. Usually, however, I don’t need that much for a long time.

MSM and DMSO

Presumably it is too biological sulfur (MSM) in the molecular association of the DMSO one of the decisive factors for the enormous successes. This also means that you don’t need to take MSM when using DMSO. After all, MSM is contained in DMSO and is released in the body. In addition, DMSO is much faster than MSM alone. This way, success can be achieved much faster.

Broadly speaking, DMSO leads to effective regeneration with rapid compensation, as a natural repair, so to speak. So DMSO helps the cells to regenerate.

DMSO syringes, infusions:

Such an application should only be made by alternative practitioners, doctors, and experienced therapists. However, they could be a last resort for very serious problems.

DMSO external use

Spraying the skin with a sprayer is a good method. I use a mixture that I can tolerate well on the relevant skin area. As a beginner, I start with 30% DMSO and increase. I make sure that the skin doesn’t burn, itch or redden too much. It should remain pleasant or bearable.

Using a brush or finger, moisten the skin lightly with DMSO. Let it soak in as completely as possible (15-20 minutes). If you are in a hurry, dab off the rest with a kitchen towel, without chemical additives. But I always take enough time for myself.

DMSO eye drops for cataracts / glaucoma

To make this, put the following liquids in a 100 ml glass bottle with a dropper pipette:
98 ml isotonic saline solution 0.9%
1 ml DMSO100
1.5 ml procaine 2% (there are over-the-counter suppliers – pharmacies).
I use disposable syringes like this for measuring. I then use these drops 2-3 times a day, 1-2 drops per eye.

There is now another method:
Here you simply use 3 – 5% DMSO in isotonic saline solution (NaCl 0.9%). On 100 ml that would be z. E.g .: 4 ml DMSO100 + 96 ml saline solution 0.9%.
However, you have to be patient. It can take several months.

DMSO eye drops to regulate intraocular pressure

One user used the following mixture for this: 30 ml saline solution + 2 ml DMSO100. To do this, take a teaspoon of DMSO100 2-3 times a week internally in a glass of water.

DMSO for emergencies

EMERGENCY: If I want to have DMSO with me in case of an emergency, it is recommended in the winter , or at below 18.5 degrees C a 70% mixture. This is because DMSO100 crystallizes below 18 degrees and can therefore no longer be used. I like to use the DMSO70% here.
With very sensitive skin, I sometimes use this DMSO 50%.

What can DMSO do?

General uses of DMSO

DMSO is reported as a drug in the medical and pharmaceutical literature. It has the widest range and largest number of therapeutic uses that no other single chemical has ever had.

DMSO has about 40 pharmacological properties that are beneficial. In the prevention, symptomatic relief or the pathological elimination of human organic diseases.

The 16 most important therapeutic properties are listed below:
DMSO blocks pain (interruption of transmission in the small C-fibers),
is anti-inflammatory, has a bacteriostatic, fungicidal and “virustatic” effect (i.e. against bacteria, viruses and fungi).

DMSO transports a wide variety of pharmaceuticals through the membranes of cells.

DMSO reduced the frequency of Platelet thrombi in the blood vessels.

DMSO has a specific effect on cardinal contractility (ability of the Heart contracting) by inhibiting calcium to reduce the workload on the heart. It acts like a sedative even when simply applied to the skin.

DMSO improves antifungal ( fungicidal ) as well as antibacterial agents when combined with it. DMSO dilates the blood vessels, probably in connection with the release of histamine in the cells and through prostaglandin inhibition. DMSO inhibits the release of cholinesterase (enzymes that break down choline esters).


DMSO tends to soften collagen due to its special cross-linking effect.

DMSO traps the hydroyl free radical.

DMSO stimulates different types of immunity.

DMSO is a potent diuretic, i.e. an active ingredient that causes water to be flushed out of the human or animal body through the kidneys. This is especially the case when administered intravenously.

DMSO drives the interferon production in the body.

DMSO stimulates the healing of wounds.

These are almost infinite possibilities how this substance can help me.

However, symptoms of diseases are not their cause. The cause of an illness and the symptoms it triggers are psychological. Everyone knows this intuitively when he listens to himself. These must be approached holistically so that not only the symptom is suppressed and treated.

I will not be persuaded that a chronic illness is incurable, because thoughts are so strong that they can also trigger what is thought. The feelings that preceded the thought are even stronger. This applies to both the positive and, unfortunately, the negative. In the case of belief, combined with feelings, this is even stronger.

So what we believe and feel, we will experience. We create our world through our thoughts. The thoughts precede everything. However, the feeling is the origin of all actions and all thoughts. Thank you about it and feel right into this topic.

Every symptom is a message and a clue. In this sense, it is important to consider what my disorder actually wants to tell me. What is the real cause? Holistic healing can be approached from different levels. Often, however, it requires attention and “treatment”, ie “lending a hand” on all levels. This means body, mind and soul.

Notes on using DMSO:

DMSO vapors should not be inhaled.
Temporary headaches may occur with intravenous administration (only by specialists) or with high doses. This can be a sign that something has gotten going a little more than the body can handle right away.
If I have a headache, I rub CDH3000 externally on some free areas on the head. I also do this at short intervals of 15 minutes if the pain persists.
By the way, toxicity (toxicity) or a carcinogenic (tumor-forming) effect could not be demonstrated by DMSO.
Because of the high penetration force, care must be taken to ensure that no contamination with DMSO gets into the body. These could damage the liver and other organs.
Apparently there are no known contraindications, writes Dr. Morton Walker. There is a free e-book from him on the Internet.
When used externally, local reddening of the skin can temporarily occur due to the capillary-expanding properties of DMSO, which can be very individual. Especially with the high-percentage DMSO100. Therefore it is better to mix externally with water to 50 or 70%. DMSO 70% is also available ready-made.

DMSO as a crystal

DMSO crystallizes below +18 degrees Celsius. First you can see several crystals in the liquid. Gradually there are more and more, until finally a very small crystal remains. DMSO does not spread when it freezes like water, no, it contracts. This is very interesting. However, when heated above 22 degrees, the DMSO liquefies again. It can be melted again in a water bath with a maximum temperature of 37 ° C. However, you should not heat DMSO too much and under no circumstances boil it, and certainly not heat it in the microwave.
When adding water, DMSO warms up temporarily in high concentration. This is a normal chemical “exothermic” reaction.

I make dilutions with pure reverse osmosis water, distilled water, or low-mineral Athesian spring water, if possible.

DMSO and the quality

DMSO is manufactured and traded in 2 different qualities.

  1. The technical quality. These should not be used on the body.
  2. The quality that is made for the pharmaceutical industry.

A small part of the DMSO from such a pharmaceutical batch is certified (examined) according to pH EUR (European Pharmacopoeia). The greater part, however, is not. It is then usually offered with the indication that it is not technical quality or that it corresponds to pharmaceutical quality. The only difference is then the certificate, not the DMSO itself. I had linked you to the products that I use myself.
