Need some help please. I am taking tbol. 40mg/day and my nipples seem to be a little more sensitive. Although i didnt think that tbol was suppose to convert to estrogen. Should I start some nolva or am I just being paranoid. I check them like 100 times a day. They also seem a little puffy. Or maybe not. Hell, I dont know. What do you think it is? Should i just wait a little longer and see how it goes or what?
