About The Grey Lab (Peptides)

The Grey Lab's companion website, which links to the group on every page, publishes scans of third-party lab reports on purity, endotoxin and heavy metals.[2] Each result is the lab's own report image, posted as-is, and failed tests are published too.[2] The site states that nothing is for sale there and adds: "Not a vendor. Informational only, not medical advice."[2]
