I feel like shit when I take Twinlabs ZMA but when I take Biotests ZMA everything is okay. There is a difference between them, but what can it be? Has Twinlab some ingredient that my body doesn?t like?

That’s interesting because the ZMA from Biotest and Twinlab both come from the same lab.
I think most major companies get theirs from Balco labs, but a couple don’t. Biotest does as I recall. I think it was EAS who didn’t.
