Verification
Documentation you can actually match to your vial.
Every Sunbelt vial carries a lot number. That lot number ties to an independent analytical report — identity and purity by HPLC and mass spectrometry — so the paperwork in your file describes the material on your bench.
- Lot-matched COAReport issued for the production lot, not a generic sample.
- HPLC + MS identityChromatographic purity and molecular-mass confirmation.
- Cold-chain handlingLyophilized, crimp-sealed and stored at −20 °C before dispatch.

Questions
Before you order.
Straight answers on documentation, shipping and research-use requirements.
Are your products for human use?
No. Every Sunbelt product is sold strictly for in-vitro laboratory research and analytical use. They are not drugs, supplements or cosmetics and are not for human or veterinary use. We do not provide dosing or usage guidance.
Do you provide a certificate of analysis?
Yes. Each vial carries a lot number tied to an independent third-party report covering identity (mass spectrometry) and chromatographic purity (HPLC). Email us your lot number and we will send the report; an online COA library is being added.
How much is shipping?
U.S. orders of $199 or more ship free. Orders under $199 ship for a flat $12.99. Every order includes tracking and ships in a plain outer carton.
How do volume savings work?
Savings apply automatically in your cart: 5% off when you have 3–5 vials and 10% off at 6 or more, across any mix of compounds and sizes. Lab supplies such as bacteriostatic water do not count toward the vial total.
What form do the peptides arrive in?
Peptides ship as lyophilized (freeze-dried) powder in crimp-sealed glass vials. Lyophilized material is stable for shipping; store at −20 °C on arrival.
