Mechabol is the active of the PH P-Mag -- and, as such, it is a far more potent product. In all other respects it is quite similar. Like P-Mag, it does not aromatize into any estrogenic compound and has no affinity for the progesterone receptor.
90 Caps (4-chloro-17α-methyl-androst-4-en-17β-ol-3-one) 25mg
4-chloro: Completely inhibits aromatization. Reduces anabolic and androgenic potency -- but the latter more than the former, which results in a favorable anabolic/androgenic ratio.
17α-methyl: Inhibits reductive metabolism by the 17-hydroxysteroid dehydrogenase enzyme, thereby increasing oral bioavailablity.
-Active compound. No conversion required.
-Remarkably resistant to metabolic reduction
-High anabolic potency
-Zero conversion to estrogen
