Every vial is independently HPLC-verified at 99% or higher, every order ships with a fresh third-party COA, and every package leaves our USA fulfillment facility the same business day if ordered before 2:00 PM ET.

Mechanism of action
Each peptide in the catalog targets a distinct pharmacological pathway: GLP-1 / GIP / glucagon receptor agonism (Retatrutide, Tirzepatide), VEGFR2 and gut-mucosa pathways (BPC-157), actin polymerization and angiogenesis (TB-500), copper-binding fibroblast modulation (GHK-Cu), mitochondrial NAD+ availability (NAD+, MOTS-c), and NNMT inhibition (5-Amino-1MQ).

Quality guarantee
Every lot of every peptide we sell we list is supplied with a lot-matched Certificate of Analysis. Identity is confirmed by mass spectrometry and purity is measured by reversed-phase HPLC, with both results reported for the specific lot printed on the vial label. The certificate travels with the order, so the documentation can be reconciled against the material on receipt. Purity is a lot-specific value: read the figure on the certificate that matches your vial rather than treating it as a fixed product attribute. Supplied for laboratory research use only.
Independent Certificate of Analysis
Every batch ships with a third-party HPLC and mass-spectrometry COA. Review the latest report before you order.
Shipping & support

Every order over $300 ships free. If anything arrives damaged or off-spec we replace it — no restocking fees, no upsell. Customer support is human-staffed and replies to research and order emails in under one hour during business days.
