If you are talking about letro, its not a bad idea to have on hand but I wouldnt use for pct. Stick with nolva and HCG and maybe some aromasin for pct. Letro is great for getting rid of gyno symptoms but really dries out your joints. Its one of those things that you will hear both sides - good/no good, ok to train on/don't bc of joint prob, etc.. I would just keep if worried about gyno, if not just use some adex eod during cycle.
