I feel like the whole filtering thing started with middle age men and women going through a mid life crisis trying to justify injecting unregulated Chinese peptides.
I’d expect a moron to “feel” instead of think. Sterile filtering peptides is standard procedure before injecting them in animal experiments, and those are professionally produced compounds not from an underground lab, but you think doing the same to protect human health isn’t worth the effort. In your case, it’s probably true.
