Every lot backed by an
independent COA

We partner with ISO/IEC 17025-accredited third-party laboratories to verify purity, identity, and potency before any product ships. No exceptions.

  • HPLC Purity Testing

    High-performance liquid chromatography confirms ≥99% purity on every production lot before release.

  • Mass Spectrometry Identity

    LC-MS/MS confirmation ensures the compound matches the expected molecular structure and mass.

  • Endotoxin & Sterility Screening

    LAL endotoxin testing and sterility assays on every injectable-grade peptide batch.

Storage & Handling

Long-Term Storage

Lyophilized peptides remain stable for up to 24 months when stored in a frost-free freezer, protected from light.

−20 °C

Reconstituted Storage

Once reconstituted with bacteriostatic water, store in a refrigerator and use within 28 days for best results.

2 – 8 °C

Cold-Chain Transit

All orders ship with gel ice packs and insulated packaging to maintain the cold chain from our facility to your door.

Avoid repeated freeze-thaw cycles. Keep away from direct sunlight and oxidizing agents. Use aseptic technique when reconstituting.

Research use only

No. All products sold by Peptide Pharma LLC are strictly for in-vitro research and laboratory use only. They are not intended for human or veterinary use, consumption, or therapeutic application. By purchasing, you confirm you are a qualified research professional.

Every production lot ships with a Certificate of Analysis (COA) from an independent, ISO/IEC 17025-accredited laboratory. You can also look up your lot number using the Lot Verification tool on this page or under the COA Lookup section of our website.

We offer standard (3–5 business days) and expedited (1–2 business days) domestic shipping, both with cold-chain packaging. International orders use DHL Express with the same cold-chain standard. Free cold-chain shipping applies on domestic orders over $250.

Lyophilized (freeze-dried) peptides should be transferred to a −20 °C frost-free freezer immediately upon receipt. Reconstituted peptides should be stored at 2–8 °C and used within 28 days. Avoid repeated freeze-thaw cycles and protect from light.

Due to the nature of research chemicals and cold-chain integrity requirements, we cannot accept returns on opened products. If your order arrives damaged, incorrect, or with a compromised cold pack, contact us within 48 hours of delivery with photos and we will arrange a replacement.
