Quality system
Why labs trust PeptideKontor
Four gates stand between synthesis and your bench. A batch ships only when all four pass.
cGMP synthesis
Solid-phase synthesis in ISO-8 cleanrooms with full batch traceability from resin to vial.
In-house HPLC + MS
Every lot is purity-mapped by reverse-phase HPLC and identity-confirmed by high-resolution mass spec.
Independent verification
A second, ISO-17025 accredited lab re-tests identity, endotoxins and heavy metals before release.
Cold-chain dispatch
Nitrogen-flushed vials ship vacuum-sealed with gel packs and temperature indicators in 24 h.
FAQ
Questions, answered
Every vial ships with a QR code linking to its batch-specific certificate of analysis — HPLC chromatogram, mass-spec identity match, endotoxin and heavy-metal screens — performed by an independent accredited laboratory.
Orders dispatch within 24 hours in discreet, unmarked packaging with gel-pack cold-chain insulation. Shipping is a $12 flat rate, free over $120. Most US orders arrive in 2–4 business days.
Keep sealed vials at –20 °C for up to 24 months. Once reconstituted, refrigerate and use within 30 days. Avoid freeze–thaw cycles; protect from light and moisture.
