Anatrofin (Stenbolone)

Anatrofin (Stenbolone) has the distinction of being Dan Duchaines favorite steroid and so I put quite a bit of effort into researching this compound, even though its not really on the market anymore. Being the favorite steroid of the Guru himself is enough to pique my curiosity. Unfortunately, hard data is err.. hard to come by with regards to this product, so well have to really examine its structure and draw conclusions from that.

Structurally, Stenbolone actually resembles Primobolan, the major difference being that instead of a 1-methyl group, it has a 2-methyl group. This is a very common alteration, and actually is the one we see when comparing Masteron and Proviron. I dont see why it was done with this particular steroid, though, as its an injectable, and this alteration is often used to increase oral availability without increasing liver-toxicity. Since it has been done, however, Im speculating that you could actually ingest this steroid orally and still see some results.but why would you want to? Anyway, as we know, those Masteron and Proviron are very similar, but for that alteration I mentioned, so we can predict Anatrofin to actually produce very similar results to Primobolan. Due to its structure (actually a 5-alpha reduced version of Boldenone), it cant aromatize to estrogen, so it cant cause estrogenic sides. However, the 1-2double bond in its structure (the same one we see with Boldenone) makes it less androgenic than Id like and Anatrofin is only half as androgenic as Dihydrotestosterone. Thus, DHT-related side effects are also probably of no great concern. Clearly, this is a very safe drug in that regard, so its easy to see why Duchaine liked it so much, stating that if he had to pick one steroid to use for the rest of his life, it would be Anatrofin.

I think 100mgs of Anatrofin injected every day or every other day would be sufficient with this drug, unfortunately, since its no longer produced, thats pure speculation on my part, as I havent been able to actually find anyone who has experimented with this stuff.
