>Go back a few years and they might be talking about nootropics or “research chemical” drugs that are analogs of methamphetamine or MDMA. Go back further and they might be bragging about doing steroids and importing testosterone from gray market sources. Go back before that and they’d be bragging about all the Modafinil they’re taking.
The peptides and nootropics are the mildest things on the list, and yet here being compared to illegal stimulants and steroids? Those are not the same crowds at all.
Given that "peptide" can mean nearly anything, I'm not sure it's safe to say they're harmless.
