I read this article on bb.com (dont hate me Dr J 😀 )
It’s the links to the store that drive me mad. BB.com are not all bad, just a too much like the print mags for my taste.
I just finished and gained almost 1/4inch on my arms. I also stopped cardio and increased my calories a tad.
That makes the claim of by 400%. Geesh, I love using statistics for evil 😈 Still Poliquins 1 Day Arm Cure claims an inch in a day!
Seriously, good strenght gains. Congratulations.
