Batch-Tested. Documented. Verified.
Every peptide that leaves Peptide Paradise Labs is backed by a lot-specific Certificate of Analysis (CoA). We don’t ask you to take our word for purity — we give you the data.
What We Test For
Each production lot is independently evaluated across five criteria before it’s cleared for sale:
- Identity (HPLC) — High-performance liquid chromatography confirms the compound matches its labeled identity.
- Purity (HPLC) — Purity is quantified against certified reference standards, with a minimum threshold of ≥98% on every released lot.
- Mass Confirmation (Mass Spectrometry) — Molecular weight is verified to confirm the correct peptide sequence.
- Endotoxin Testing — Bacterial endotoxin levels are tested per pharmacopeial standard (USP <85>).
- Sterility & Heavy Metals — Lots are screened for microbial growth and heavy metal contamination prior to release.
How to Find Your Certificate
Every product page lists the current lot number for that SKU. If you need the CoA for the exact lot printed on your vial, contact our support team with your order number and lot ID and we’ll send the matching report directly — this protects against outdated or mismatched documentation being circulated publicly.
Why It Matters
Research data is only as good as the material it’s built on. Lot-matched documentation means you can trace every result back to a dated, verifiable certificate — not a generic manufacturer spec sheet.
