hmm, just my 2 cents, but, from my experience:
"epistane" gives a good boost in libido, & some strength increases, more of a long term effect to me.
formestane does give a pretty rapid increase in libido & "feeling of well being"/"aggression", but also only does this for me, for only a few days before i get the opposite effect.
as for the trifecta stack, it has a bunch of what seem to be non-methylated chems, despite it being called methylated? maybe i missed something. any time i see piperine in the recipe, i wonder about it's bioavailability, but who knows, might work great for you. the yohimbine will light up your libido... not to piss off any of the sponsors, but the claims of 20lbs of lean muscle added in a short time are unrealistic. water gains of various kinds generally, & oh how depressing it is to pee off all your muscle after a cycle!:haha:
THANKS to all of our magnificent defenders of freedom around the globe on this Independence day weekend!!!:usa:
