I have. Loved the results
I recently bought some at 3-4.00 a amp and was worried it was bunk, let me tell you ITS NOT!!!!!!
My bro who is a bigtime hardgainer took 500mg a week for 16 weeks and packed on 24lbs.
I still have a bunch left for another couple cycles down the road.
BOTTOM LINE......If it is not BUNK, You will be VERY happy.
