Alphaviron (mesterolone) is basically an orally active DHT (Dihydrotestosterone) preparation .For comparision, we can think of some other orally prepared DHT compounds like Winstrol, Anavar, etc& Those both act very similarly in mechanism to Alphaviron, but a more accurate way to think of this compound is as something like “Oral Masteron.” As Im sure you noticed, their anabolic/androgenic ratio is very , DHT is 3 to 4 times as androgenic as testosterone and is, of course, incapable of forming estrogen. Also, Alphaviron is quite unique in that a simple look at its 4-ring structure will show us that it is not going to be too liver toxic, since it is not c17-Alpha-Alkylated, as many orals are& this modification (lacking in Alphaviron) makes drugs more liver toxic. Alphaviron has a 1-metyhl group added, instead. Looks pretty great on paper, right? Well, as usual, things tend to look better on paper than they do in the body. Your body has a negative feedback loop which prevents your body from having too much DHT floating around(if youve been paying attention up to now from reading my other stuff, you already know this). An excess of DHT will eventually be changed into another (largely not anabolic) of course, being a DHT-based compound, Alphaviron isnt going to be great for female athletes to use. Virilization (development of male sexual characteristics) is going to be a concern for women daring enough to try this stuff. My advice is that there is much better, safer compounds for female athletes and bodybuilders to use..
Different testosterone esters are often blended into one injectable preparation. In some cases up to seven esters are used, but the most popular formulation is that of Sustanon 250 where four esters are mixed together. This is done to take advantage of the faster acting esters while still only requiring weekly or bi-weekly injections. It is often believed to be a superior form of testosterone, but in reality it’s nothing more than just testosterone. One drawback of testosterone blends are that they incorporate esters with long carbon chains and those chains occupy allot of molecular weight, so the actual dosage of hormone is less than one would obtain from shorter esters like propionate. Testosterone blends are most useful during bulking phases where frequent injections are not possible.
