I'm experiencing some gyno symptoms during my second cycle of testosterone at 300mg a week. It's mild, just on my left nipple, where I can feel a hard mass forming behind it. I don't have access to any AI (aromatase inhibitor), but I do have Nolvadex. Should I start taking Nolvadex to prevent the gyno from getting worse? I've heard mixed advice about using Nolvadex during a cycle, but it's all I have. What do you think I should do?
