The compound listed on the label here is 4-chloro-17a-methyl-andro-4-ene-3,17b-diol, but I've indicated it as 4-chloro-17a-methyl-andro-4-ene-3b,17b-diol. When I look up 4-chloro-17a-methyl-andro-4-ene-3,17b-diol, i get results telling me this is Promagnon, so I'm going with that.

Lots of posts on the Internetz indicating Promagnon is very similar to Halodrol, but they're aren't the same. The compound is almost identical chemically to oral Turanabol. Oral Turanabol has all the size effects as D-Bol, but doesn't aromatize. Aromatase is an enzyme that elevates when testosterone levels rise with the purpose of converting testosterone to estrogen.

17-alpha-alkylated steroids (like P-Mag) aren't broken down by liver enzymes, which means liver support supplements are recommended while you're on cycle. Most P-Mag users report steady gains in size and strength. P-Mag works well on its own, although you could stack with a non-methyl for additional gains.

Professional and amateur athletes subject to performance enhancing substance testing should consult with their sanctioning body before using this.

4-chloro-17a-methyl-androst-4-ene-3b,17b-diol (Promagnon)

Also sold as Promag, P-Mag
Common Dosage: 50 - 100mg daily
Common Cycle Length: 4-6 Weeks.
Methylated: Yes
Half-Life: 12 hours

Another methylated prohormone, this one is often compared to halodrol, though there is an important structural difference. P-mag lacks the C1-2 double bond common to boldenone derivatives like h-drol, boldione, dbol and M1,4ADD, having only a C4-5 (delta-4) double bond which makes it a closer structural relative of testosterone and methyl testosterone.

The difference becomes apparent when we look at what each one becomes in vivo: where some h-drol is metabolised via 3b-HSD to oral turinabol, p-mag becomes methylated clostebol. A 4-chloro group is common to both drugs, which will make both poor substrates for the aromatase cytochrome P-450 enzyme.

Clostebol is a synthetic anabolic androgenic steroid. Clostebol is the 4-chloro derivative of the natural hormone testosterone. It is a weak anabolic steroid used often by Germans during their Olympic glory days.

Promagnon users report size gains, with a lack of additional weight added in the last couple of weeks. Libido tends to remain positive, likely due to the more androgenic qualities of the drug.

The aforementioned positive attributes and the possibility of short cycle durations would make this an excellent choice for a first cycle, though as with any methyl it is a good idea to educate yourself about the possibilities of hepatic impairment

Promag is a versatile compound that will produce lean muscular gains and is suitable for cutting or bulking, however is typically most used when bulking Promag remains a popular due to minimal side effects and consistent dry gains that are relatively easy to maintain post cycle.

Dicalcium Phosphate

Dicalcium phosphate, also known as calcium monohydrogen phosphate, is a dibasic calcium phosphate. It contains about 29.5 percent calcium in its anyhydrous form. Manufactured from phophoric acid, dicalcium phosphate is used as an antioxidant in food, an abrasive agent in toothpaste (dicalcium phosphate dihydrate) as well as being a firming agent

Dicalcium phosphate is mainly used as a dietary supplement in prepared breakfast cereals, dog treats, enriched flour, and noodle products. It is also used as a tableting agent in some pharmaceutical preparations, including some products meant to eliminate body odor. It is used in poultry feed.

In some instances, DCP can seriously effect the absorption of other supplements. According to the June 1997 Journal of Clinical Nutrition, the zinc absorption by people ages 59-86 was reduced by 50% when a calcium-containing supplement was given with the meal.

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.

Stearic Acid

Stearic acid is the saturated fatty acid with an 18 carbon chain and has the IUPAC name octadecanoic acid. It is a waxy solid, and the salts and esters of stearic acid are called stearates. It occurs in many animal and vegetable fats and oils, but it is more common in animal fat. The important exceptions are cocoa butter and shea butter, whose fatty acids consist of 2845% stearic acid.

Stearic acid is used in making candles, plastics, dietary supplements, oil pastels and cosmetics, softening rubber, and hardening soaps. Stearic acid is used in aerosol shaving cream products. It is used along with simple sugar or corn syrup as a hardener in candies and to form margarines, shortenings, spreads, and as a cream base for baked products.

Even though stearic acid is a saturated fat, studies have suggested that it has little effect on blood cholesterol levels, because such a high proportion is converted to oleic acid.
