Why would you want to use mag-10 3 weeks before the show?
I will reduce my bodyfat to 3.5% but unavoidably lose lean mass
You're going to gain 7-10lbs of muscle in 2 weeks!!??!!??
Musclemania tells you they drug test, but chances are that you won't be tested at all.
On the other hand, if you were tested, I was told by the guys at T-Nation when MAG-10 came out that I would fail the drug test if I used the product.
