Built block by block

Valence Bios supplies research peptides as sealed vials of freeze-dried powder, each labelled with its lot number. Every lot is sent to an independent third-party laboratory, and the certificate is published as the lot is released. Until then, the product says "COA pending". We never publish a purity figure that a real document does not back.

What we hold ourselves to

• The testing laboratory is named on every published certificate.
• We sell for laboratory research use only, never for human or veterinary use.
• We ship within the United States only, by FedEx 2Day, cold-packed.
• All sales are final. We replace or reship only for damage, loss in transit or a wrong item.
• We advertise only the payment methods that are live.
