Here is what I found on the World Doping list of banned subs...
boldione (androsta-1,4-diene-3,17-dione);
Here is what Tren Extreme has:
19-Norandrosta 4,9 diene 3, 17 dione
Seems like it might be illegal, but anyone with more info please correct me. I'm just trying to help people out with the more info on products claiming to be natural/non-steroidal.
