When i first joined this site many years ago and did my first cycle, everyone was all about running tamox/letro(or similar substance) and proviron DURING your cycle and throughout PCT. now i'm back on the boards a few years later and everyone is all about running these only for PCT or IF you start to detect gyno symptoms. why is that? i hear about hindering gains and what not but when did the protocol on proper cycling change? and how many ppl really notice the difference between running these things during or after your cycle?
