pretty sure its just about unmethylated phera, but theres also another hormone in there read on... the following was taken from the AX forum.
" 2-Androstenol does have an acetate ester on it. However, 2-androstenole's sole and only purpose is as a very potent pheromone. In it's current state as listed on the ingredient label, it has shown to increase levels of aggression and dominance, as well as levels of LH.
2-Androstenol by itself has no anabolic/androgenic activity. If you look it up in Vida, you will find that it is worthless as an anabolic/androgenic compound. However, as a pheromone, it still has the ability to impart profound psychological effects, which is why we chose to use it in the formula.
Androsterone's conversion into Stanolone, and 11-Alpha's effects are the primary anabolic drivers in this formula, and are directly responsible for the crazy insane gains that are being reported in the logs. Matt, once again, really nailed this formula and the gains people have achieve with 3-AD so far, and with Mass FX MS are a true testament to the potency of 11-alpha. Combine 11-Alpha with the right supporting cast, ie Androsterone, and you get a truly phenomenal product.
hera-Plex was methylated 2-androstenol. So while you could say that this is unmethylated phera, the lack of the methyl group completely deactives 2-androstenol as an anabolic, yielding zero anabolic/androgenic activity. 2-Androstenol was included in the formula for it's very potent pheromone effects on the psyche.
Androsterone is the true anabolic monster in this formula. 11-Alpha's effects on protein synthesis and nitrogen retention work in perfect synergy as Androsterone converts into Stanolone."
mind you, this is obviously the tone of an AX rep, but, i can say ihave had nice results with this product, as well as MMv2. at the end of the day, they are very similar products, with target conversion to stanalone.
