[definitelymaybe]

I feel your pain. I can't gain weight either. It's very very hard for me to grow and I've been at this for over 2 years now. But if you stick with it, hopefully you will make progress. I'm on Ainterol PM now and it seems to be giving me more tingles and growth than the other brands of PM that I have tried.

I get more tingles when I take a calcium supplement with my PM. I also like to swallow a little bit of black pepper as well. It sounds weird but it helps with absorption.

Good luck!
