I don’t know who “them” is, but I think you give them too much credit.
Small brand wants XYZ product, finds contract manufacturer who is “cGMP compliant”. Said shitty contract manufacturer finds even shittier Chinese supplier, orders DMHA, gets watered down DMAA, nobody anywhere down the line tests (except Pieter Cohen, apparently!) and nobody knows except the 1% of experienced users like @M3NTAL who never got consistent results.
It’s customs fraud but how do you track these Chinese companies? They dozens of business names and just as many email addresses. Go after the brand? Sure but there’s 10,000 YouTube kidz who want to make a new pre workout and blast it on Amazon for a year.
The only solution is to obliterate those breaking 21 CFR Part 111, and obliterate them hard. Mistakes of course happen and that’s what recalls are for, but his is systemic for some of them.
It’s a sad day when I need to email Alex and Steve at MAN Sports and thank them for not breaking the law.
