Did you know Ozempic is a peptide. Mounjaro is a peptide. So is the BPC-157 arriving in your colleague's letterbox from an unnamed supplier with "research use only" on the label. And so is the collagen powder someone at your desk is stirring into their morning coffee.
Peptides are not a trend. They are a class of biological signalling molecules that includes some of the most rigorously evidenced medicines of the past decade - and some of the most speculative, poorly regulated, and inadequately monitored substances in the UK grey-market wellness space.
The clinical evidence for GLP-1 medications is exceptional. The human evidence for BPC-157 is essentially non-existent. The collagen peptides in that protein powder? Reasonable, actually.
The problem isn't peptides. The problem is that the enormous variation in evidence quality, regulatory status, and safety profile is invisible to most people using them.
And almost nobody is testing their blood before they start.
Whatever you choose - measure it and 'Pep' responsibly.
