there has been much talk on this board lately about not even using an AI in PCT. also some have suggested to run your AI after your SERM only. my personal opinion on AI use is after the SERM, at a low dose for a couple of weeks to prevent rebound. i am currently using a 6-bromo product at a low dose, then decreasing over the course of 3 weeks total. currently, i am not experiencing any gyno issues, or libido issues, actually libido is high right now...
Atd can drive estrogen too low, and is also an anti-androgen. This causes people to have low libido. Some people also blame it for alot of the rebound gyno problems in the last few years, but that has not been proven.
Not sure if I'd trust L. Rea..Im not familiar with that study. I was first exposed to the anti-androgen idea on several threads on here over the past year or so. My main reference for saying it was an anti-androgen was a write up by Author L. Rea I believe. Not trying to misled but I haven't seen anything to the contrary.
