it looks like hyperdrol and massfx seem to be the most popular supplements on this board. im currently on a cycle of hdrol/havoc. when im done w/ pct could i run these two? my only worry is how running test boosters for so long will effect my endocrine system...? i heard this guy at my gym tell me someone took test boosters for like 6 months and had problems with his natural levels... definetly not worth the risk if this can happen.
