I was using T-400 but it was just too uncomfortable and problematic so I have switched over to Omnadren. The odd thing is I am getting really no pain at all (normally sust would make me sore for a few days). This would be of little concern but I have actually lost 3 lbs. this week and am concerned that they may not be the real deal. Except every photo I have checked would indicate they are real as can be (and I have checked alot). Do any of you other guys here get no soreness from omna's, the search I ran came up with mostly guys wimpering in pain from them...keep in mind that I am quite tolerable to the pain and use massage to alleviate it quite well, even with the T-400.
