Cyanostane Rx contains Cyanostane and Dymethazine. It's an anabolic compound with low androgenic action, making it similar to Oxandrolone or Methenolone.

It is non-aromatizing, meaning it won't produce estrogen mediated side effects. Its high degree of anabolic action makes it a good choice for athletes concerned with losing body fat while maintaining or increasing muscle mass.

Cyanostane is relatively new. It features an alteration of the Superdrol compound, with a cyano bond instead of the 2a methyl Superdrol bond. Bloodwork shows Cynostane has a more favorable effect on blood lipids and liver values than Superdrol. Although feedback to date is limited, the combination of low androgenic action, lack of aromatization to estrogen, and low level of general health effects, makes cynostane an of interest.

Cyanostane is not liver or lipid toxic. This compound definitely has high oral activity. It has the highest Q ratio, 20, the same Q ratio as Superdrol. Expect dry gains, similar to Oxandrolone (Anavar).

Dymethazine has been compared to Methyltestosterone, Oxymethalone, Androstanazole and Testosterone Propionate in their protein-anabolic activity. Dymethazine was shown to have the highest muscle building effects out of any of the previously named steroids (Methyl-Test, Anadrol, Winstrol, and Testosterone Propionate). In addition, it also displayed an ability to induce a higher rate of Nitrogen retention than Methyl-Test.

In another study, patients were administered Dymethazine for 45+ days. Liver values did not change for 50% of patients, while the other 50% noticed only modest to moderate increases in liver values. So while Dymethazine can increase liver values, the effect can be minimal. This means Dymethazine can be run for longer with a reduced risk of adverse liver effects. Dymethazine doens't casue estrogen related side effects.

Recommended real-life dosage for Cyanostane is 30mg daily, with advanced users going as high as 40mg daily for the last 2 weeks of the cycle. Two capsules here gives you the optimum 30mg daily.

Dymethazine dosage recommendations range from 15mg a day for first time users to as high as 45mg a day for the last 2 weeks of a cycle for experienced users. Two caps here puts you at 20, which is good for new users, but might not be adequate for experienced users.

New users might see best results with the fewest sides at 2 caps per day for the full 4-6 week cycle, with experienced users start at 2 caps per day, and finishing at 3 caps for day for the last 1-2 weeks of the cycle.

17b-hydroxy-2a,17b-dimethyl-5a-androstan-3-one-azine (Dymethazine)

Trade Name: Dymethazine

Dymethazine (aka mebolazine) was brought to market by iForce Nutrition in 2009, however, despite Dymethazine being 'legal' it was largely taken off the market due to recent FDA activities. Despite this, clones of the original Dymethazine have already been brought to the market. Dymethazine and DZine are interchangeable featuring the same compound (2,17-dimethyl-5-androstan-17-ol-3,3-one-azine)

Dymethazine is an azine, two superdrol molecules attached to each other by a nitrogen atom. Stomach acid separates the two superdrol molecules from each other, after which they make their way to the androgen receptors. Dymethazine is also known as mebalozine.

Dymethazine is nearly identical to Superdrol, except it's two (as opposed to one) superdrol molecules attached to each other. Your body's stomach acid separates these two molecules prior to absorption, so it becomes a single molecule with two potential pathways. Despite this difference, Superdrol remains the more powerful compound.

The one advantage Dymethazine has over Superdrol is the lower likelihood/greater managability of side effects. Dymethazine is an incredibly potent compound and carries the same risks as any other powerful anabolic steroid or pro-hormone.

In a study, patients were administered Dymethazine for 45+ days. Liver values did not change for 50% of patients, while the other 50% noticed only modest to moderate increases in liver values. So, while Dymethazine can increase liver values, it is not as harsh as the current strong methyls currently available.

Dymethazine features 0% ability to aromatize and expresses an extremely weak androgenic activity. This means Dymethazine will produce gain with little to no liver impact and will cause no estrogen related side effects.

2-cyano-17a-methyl-17b-hydroxy-androst-3-one (Cyanostane)

Also called Cynabol

Cyanostane is a new prohormone which features an alteration of the superdrol compound, with a cyano bond instead of the 2a methyl superdrol bond. It's relatively new with few reviews.

The chemical structure is the same as methyldrostanolone (Superdrol), except it has a cyano group on the 2 position instead of a methyl group. It is a C-17aa steroid and it will be liver toxic, although, due to the lack of the 4-ene on ring A and lack of 2-methylation, liver toxicity may be reduced relative to a di-methylated steroid such as Superdrol.

Expected results would be lean gain as this compound cannot convert to estrogen. Based on the chemical structure the anabolic potency would appear to be fairly potent with moderate androgenic potency.

There seems to be a nomenclature mistake on the labeling for this steroid. The chemical name contains the term "androst", assuming that there is some sort of ene group on ring A. But there does not seem to be such mention of an ene group on ring A. Therefore, the term androst should be androstan. But if this is the case, the 2-cyano group needs to be stated as alpha or beta. This makes a big difference, since usually C2-alpha groups are significantly more effective than beta.

There are studies about other 2-cyano steroids such as 2-cyano-DHT and 2-cyano-progesterone. In separate studies, one done on dogs, it was seen that both of these 2-cyano steroids caused inhibition of 3b-HSD enzyme. This inhibition would cause severe adrenal suppression. This is a very unsafe inhibition. Whether it occurs in this cyano steroid is unknown, but users need to be aware of this possibility.


Gelatin is a tasteless substance created from collagen found in animal skin and bones. It is used to thicken liquid in processed foods as well as having applications in photography, cosmetics, and pharmaceuticals. Gelatin is found in many forms of candy, marshmallows, Jell-O, and some types of yogurt. Gelatin can be bought in many grocery stores for use in home cooking. In the vast majority of cases, gelatin is not harmful to the consumer.


Hypromellose (INN), short for hydroxypropyl methylcellulose (HPMC), is a semisynthetic, inert, viscoelastic polymer used as an ophthalmic lubricant, as well as an excipient and controlled-delivery component in oral medicaments.

Hypromellose is a solid, slightly off-white to beige powder and may be formed into granules. Although non-toxic, it is combustible and can react vigorously with oxidising agents.

There are many fields of application for hypromellose. These are not limited to the following:

Tile Adhesives
Cement renders
Gypsum products
Paints & Coatings
Detergents & cleaners
Eye Drops

Magnesium Stearate

Magnesium stearate is often used as a diluent in the manufacture of medical tablets, capsules and powders. In this regard, the substance is also useful, because it has lubricating properties, preventing ingredients from sticking to manufacturing equipment during the compression of chemical powders into solid tablets.

Magnesium stearate is the most commonly used lubricant for tablets. Studies have shown that magnesium stearate may affect the release time of the active ingredients in tablets, but not that it reduces the over-all bioavailability of those ingredients.


Microcrystalline cellulose is a term for refined wood pulp and is used as a texturizer, a anti-caking agent, a fat substitute, an emulsifier, an extender, and a bulking agent in foods. Microcrystalline Cellulose is derived from high quality wood pulp. While cellulose is the most abundant organic material, Microcrystalline Cellulose can only be derived from a special grade of alpha cellulose.


Polyvinylpyrrolidone (PVP), also commonly called Polyvidone or Povidone, is a water-soluble polymer made from the monomer N-vinylpyrrolidone.

PVP is soluble in water and other polar solvents. When dry it is a light flaky powder, which readily absorbs up to 40% of its weight in atmospheric water. In solution, it has excellent wetting properties and readily forms films. This makes it good as a coating or an additive to coatings.

It's used as a binder in many pharmaceutical tablets. Autopsies have found that crospovidone does contribute to pulmonary vascular injury in substance abusers who have injected pharmaceutical tablets intended for oral consumption.

The long-term effects of crospovidone within the lung are unknown. PVP added to iodine forms a complex called povidone-iodine that possesses disinfectant properties. This complex is used in various products like solutions, ointment, pessaries, liquid soaps and surgical scrubs. It is known for instance under the trade name Betadine.

As a food additive, PVP is a stabilizer and has E number E1201. PVPP is E1202. It is also used in the wine industry as a fining agent for white wine. Other references state that polyvinyl pyrrolidone and its derivatives are fully from mineral synthetic origin. Therefore, its use in the production should not be a problem for vegans.

Silicon Dioxide (Silica)

The chemical compound silicon dioxide, also known as silica, is an oxide of silicon. Silica is most commonly found in nature as sand or quartz.

Silica is common additive in the production of foods, where it is used primarily as a flow agent in powdered foods, or to absorb water in hygroscopic applications. It is the primary component of diatomaceous earth which has many uses ranging from filtration to insect control. It is also the primary component of rice husk ash which is used, for example, in filtration and cement manufacturing.
