Primodex 50

General information:

Manufacturer: Sciroxx
Substance: Methenolone Acetate
Pack: 10 ml vial (50 mg/ml)

Methenolone Acetate is an anabolic steroid which became very popular once it was claimed that it was one of Arnold’s favorites. I’m not really sure why this is, or how likely it is that Arnold went around telling everyone’s favorite steroid- but nonetheless, this rumor has persisted through the years.

One of the other very interesting facts about Primobolan is that it’s one of the very few compounds available as both an oral as well as an injectable. Unlike Winstrol and Dianabol (both alkylated and non-estrified steroids) however, which are also available in both forms, Primobolan is available with an Acetate ester for use as an oral, and with an Enanthate ester as an injectable. Unfortunately, in this case, making Primobolan a non-17-alpha-alkylated steroid greatly reduces its potency. However, it must be noted that this alkylation is what makes oral steroids survive their first pass through the liver; it also makes them hepatoxic (liver toxic). Oral Primobolan doesn’t actually have this drawback, and thus it is very mild on liver function and doesnÂ’t elevate liver enzymes too much. Instead of the more toxic 17a-alkylation, Primobolan (Oral) uses 17 beta estrification and 1 alkylation to make it orally available. For both men as well as women, daily dosing of the oral is necessary, although men would probably want to take 100mgs per day and women would need to take at least 10mgs every day.

Although it is typically considered to be a very mild drug when inhibition of the natural hormonal profile is considered, this isn’t totally true. Men were given a 30-45mg dose of the oral version of Primobolan, experienced between a 15% and 65% decrease in their Gonadatropin levels (4). Since we’re probably looking at double or triple that dose, for men to get any kind of results, it’s also probable that gonadal inhibition will also be increased.

My history with Primobolan Enanthate (the injectable version) has been less than impressive. I used it at 200mgs/week about a decade ago, and wasn’t impressed at all. A couple of years ago I went back to it and used 350mgs/week (100mgs/Every other Day), and got much better results, but still wasn’t overly impressed with it. Add to that the fact that it is an expensive chemical, and I really wasn’t impressed.

On the Black Market, Primobolan tabs are only being produced by British Dragon currently, although PaperPrimo is being produced as well. Both are high quality products, although I would speculate that their use is going to be reserved for women. With regards to the injectable version, many underground labs produce it, and quality tends to vary, due to powder quality at the moment. Expect to pay around $100 for a 10ml bottle dosed at 100mgs/ml, if not more. Finally, ampules are available at a cost of roughly $7-12 per amp, but since this is the most widely counterfeited steroid on the black market, I’d stick to the underground lab variety.
