The study takes 150 random products and finds issues with 20% of them, I guarantee those 20% are not sold at GNC, VitaminShoppe etc.
This is just really not a big problem for normal every day people.
> Since FDA sampling has focused on dietary supplements found online or through import screenings, this data analysis does not indicate the prevalence of these adulterated supplements at retail locations.
But I would not have confidence in what is sold at retail. A 2015 operation by NY state found problems with supplements sold by GNC, Target, Walgreens and Walmart: https://well.blogs.nytimes.com/2015/02/03/new-york-attorney-... Granted, I don't think they found any actual drugs in the supplements, but many of the supplements did not contain what they claimed to contain, and some of what they did contain are potential allergens.

Literally the only surprising one on the list is Slim Fast, and it's so surprising I'm wondering if they are using extremely old stock or something. The rest of the "supplements" are dick pills with names like "Sexy Monkey."
It's just not even the same market as the weekend warrior crossfit bro who takes whey protein and maybe gasp creatine.
The general problem is that whatever you look at you are likely to find a type of contamination that isn't being checked for with the same level of oversight as the food industry or the pharmaceutical industry.
It's crap, but it's not on the list.
It is on the list, and now that I look closer, yes the stock they are using is from 2009 when Slim Fast openly advertised that they used sibutramine. They have since stopped, so this list is somewhat suspect.
The "Slim Fast" that is on this FDA list is a knock-off from "Universal ABC Beauty Supply International, Inc."
Didn't GNC sell Superdrol and other designer steroids and pro-hormones?
