I've been looking around on custom nutrition warehouse and started reading about M5 (17a-methyl 5alpha Androstenediol). It says that it acts as an aromatase inhibitor, so my first question is....would this be good to use as an anti-estrogen as they suggest? Secondly, they imply that it has a powerful stimulant effect....would this be effective to battle the possible lethargy from M1T? I've never heard of this compound, and I'm hoping someone with expertise on prohormones can shed some light on what exactly M5 is.
