What I wish I would have known right when I started TRT
That Pregnenolone wouldn't cause any issue with e2 leves, but DHEA might. Pregnenolone appears to be enough, and should be supplemented. I started to barely develop gyno because my e2 levels were getting so high, because of dhea. I dropped the DHEA and now e2 levels are very manageable with out a true AI.
