About us
Built by researchers, for researchers.
Grey Peptides was founded with one purpose — make lab-verified research peptides accessible to serious researchers, without the markup, vague sourcing, or guesswork.

Purity is the product.
Peptide research is only as reliable as the compound on the bench. That's why every batch we sell is independently tested using reverse-phase HPLC and mass spectrometry — and why we publish Certificates of Analysis on request.
We hold inventory in Australia and ship globally with tracked, discreet packaging. No middlemen, no relabeled vials.

Our promise
If a vial arrives compromised, mislabelled, or doesn't match its COA, we replace it. No paperwork olympics — just send a photo and we'll make it right.
