I inquired a little about this product Hulk.
A gym colleague, (I wouldn't call him a friend) has been taking it for some time now, after elongated periods of creatine, protein and amino usage. He said the Trenabol, is producing gains that the "standard" stuff never did and to be honest he is looking huge. As a gym instructor, he's adamant that it's not a steroid, but he shyed a little when I stated it was banned in France etc.

Anyway, although he does have a few extra spots, there were no other side effects as such.
He seemed healthy (although neglecting cardio) and like I said, he has visible results.
