After a week or so, downstairs was hurting and growing a little. That stayed for a week or two, then nothing happened for two months. Not even acne as a lot of people seemed to get as one of the first 'changes'. After 2-3 months I very slowly started to get the usual changes, such as a very slight voice drop and a little more hair on my stomach. I'm now 5 months in, and my voice has dropped (not enough imo) and my stomach is hairy, plus I have the worst case of acne. But that is about it.
