I've had a little of that trouble. I do mean a little, hardly noticeable and def. not brown liquid, just clear. I think you've gotten some good advice on this thread. I used femera and cabaser, but the thing that seemed to help the most was staying off everything for more than 6 months or so. Also, tell you friend to consider carefully what he was using or what combination of things caused this. When I had this trouble I had used prop and tren with nolvadex and t-3. I looked like shit on this cycle too. I don't know what I was thinking back then (only 2 yrs ago lol). I'm guessing some combination of things caused this. I believe mine was the tren with nolva, a definate no no for me. Also, I'll never touch t-3 again. I didn't get ripped but I was flat as hell. I stayed off for many many months, changed some things and have had no problems since. Good luck!
