Biotest Alpha Male Testosteron Booster

Biotest uses three Testosterone-boosting extracts that are the benchmarks for the sports-supplement industry: tribulus terrestris, vitex agnus castus and eurycoma longifolia. Each of these compounds is super concentrated to achieve maximum potency. Furthermore, Biotest evaluates every batch of raw material to ensure that each finished bottle performs at the highest possible standard.
Although in some aspects similar, these compounds achieve their T-boosting effects through different mechanisms. Even though no one knows for certain how they actually work, the predominant theories are as follows:
Tribulus serves as a luteinizing-hormone secretagogue (LHS). In other words, it causes the release of luteinizing hormone, which in turn signals the testes to produce more testosterone. And of all the T-boosting compounds on the market, tribulus is the most powerful.

Vitex also works as an LHS but it also acts as an anti-progesterone and anti-prolactin agent, lowering progesterone and prolactin. Progesterone and prolactin are particularly nasty hormones, in that they cause - much more than estrogen - storage of body fat and mental depression. Prolactin can even cause lactation in men. And, by lowering progesterone and prolactin - just like lowering estrogen - you’ll increase Testosterone through various feedback mechanisms.

Eurycoma imparts its effects by selectively controlling the conversion of DHEA and other naturally occurring androgens into Testosterone. In fact, it even works when the testes are non-responsive to Luteinizing hormone. As long as the substrate hormones are present (and they’re present in everyone), Eurycoma works. In addition to these powerful extracts, Alpha Male contains a full dose of Carbolin 19!
