been on the chinese durabolin for about 12 weeks now. but seems good, but some days i am more pumped then others. been shooting 3mls a week=600mgs, and havent had any problems. was mixing it with other stuff before, now i'm just using it with anavar and fuzabol. all chinese. the anavar feels week but the fuzabol is definetly there. i usually never respond, just read, but i have alot of respect for serge, and wanted to help. peace.
