Seriously, that testing is a joke, and I've seen tons of it.
I had a reseller US domestic testing for endotoxins many batchs, they are never detected, always showing the "<**" thing.
Heavy metals same, and I've seen plenty, on raws and others, they are never found, even janoshik said that many times that he almost never find heavy metals in steroids.
As for the sterility thing, the peptide users did tons of it for a while, some of them are shared here, like GHK CU, Tirz, HGH 36iu and plenty of others, they realised that it's useless test based on completely random results, no one waste his money on those tests anymore.
But yeah let them doing that, they can cocksuck any new/existing sources who's trying to get some praise by doing those stupid tests, it doesn't change a thing in my business, I spend a minimum of $10,000 on testing monthly, sometimes more and sometimes less, the company no longer counts or take the testing costs in consideration, it's a small fraction of costs, if I test the whole price list for sterility, hplc, endotoxins, heavy metals, I could move on without the need to raise prices with a single 1$ and justifying it by testing costs.
But it's useless tests. Beside HPLC, quantities, purity, all the rest is useless, and a waste, not playing this game.
If it was something useful, I'll be the first one doing it, being the first one to test tirzepatide in this forum, multi tabs among chinese and many others, I prefer to spend that money on degradation tests like I did on HCG and learn something, rather than get a serie of "PASS".
