Question on this though: I've heard though not experience or confirmed, that using nolva during a cycle lowers its effectiveness during PCT. I'd like to know if you guys think that's true or not. I'm particularly prone to gyno it seems, after three days of manufacturer's suggested dose of 4 Derm my nipples were sore as hell on my last cycle. I ditched the cycle and did a full PCT. This is why I've stuck to 1 test trans and very lightly dosed if any 4 AD trans cycles.Now I could use nolva during the cycle to control for this tendency but I don't want it to be less effective during PCT.
