What did he eat and what did his training look like? My friend and i took the same thing for our first cycle, Deca200 for 8 weeks and i gained weight and he lost weight,but it was the same gear. He just trained like shit and ate the way he trained.......
and it's only been 2 weeks, some people take longer than others.
Take a picture of the gear and post it bro-- we may be able to identify if it's legit or not.
You may have gotten it from a ass-whore dealer who just filled the thing with who knows what... and slapped it with a brand name label. Unfortuanally it does happen to some.....
Is the dude cutting, because i would love to gain 3 lbs now, lol. I have never heard of supra fakes and i seriously doubt their are any out their. Why don't you outline his stats, lifting history, age, and some other things.
