A friend of mine is having some issues with sore nipples. He currently is taking 1ml Prop and 1ml Tren A EOD. I know there is minimal conversion to estrogen but my assumption is that he has extra sensitivity to estrogen. Either way he started to use Nolvadex for around two weeks now with no reduction in sensitivity, me next suggestion was Arimidex but I have a feeling it may be something different all together. Any suggestions? I was thinking Letro but it may be to strong.
