So i have a quick question, i have been on my cycle of test 400/deca 200 for exactly a week today and it feels like my left nipple has gotten a little more puffy, i have nolva on hand, but i was wondering about the dosage, i don't want it to hinder my gains either, but i don't want my gyno to get worse, so what do i do? should i start nolva right now? what is the best Aromatase inhibitor (AI) for gyno while on cycle without it hindering gains? or is there one?
