looking for proven supps that increase receptorand sensitivity, and by proven I guess I mean it's been tried by the AM community in general and accepted. Only three that come to mind are
JW- increase receptor sensitivity
Xfactor- increase density and sensitivity
Viraloid- "opens" additional receptors (not sure if 'proven', going off product literature)
just trying to come up with stacking options for supps that are very anabolic in nature and get some really good synergy going.
opinions appreciated. thanks
