I did a month long 30/30/30/30 cycle of epi(cel e-stane) with a bridge into 11-oxo for 15 days. I started my pct during the 11-oxo bridge. I've managed to keep all of my gains and even gain some strength during my pct(natty test booster but had a serm on hand). My question is how long should I wait between cycles? I'm planning on trying h-drol next for 6 weeks (i've never done 2 cycles within a year don't ask me why). I haven't had blood work done and don't really plan to unless its absolutely necessary. I've been off epi for 5 weeks now 11 oxo(i'm not sure if that counts for anything) for 3 weeks. Should I wait 90 days or whatever it is from the end of my epi cycle or the 11 oxo? I think I read somewhere on here that it is 6-8 weeks between cycles. I'll err on the side of caution.
