Verification
Certificate of Analysis on every batch
Purity claims mean nothing without paperwork. Every compound we fill is released against an independent HPLC and mass-spectrometry report tied to a single LOT — and you can request that exact report for any vial you own.

What we test, on every single batch
HPLC purity ≥99%
Reverse-phase high-performance liquid chromatography quantifies the main peak and every impurity above the detection threshold.
Mass-spec identity
ESI-MS confirms the observed molecular weight matches the theoretical mass for the sequence — proof the vial holds what the label says.
LOT traceability
Each vial carries a LOT/REF code that maps to one synthesis batch, one fill run and one analytical report.
Cold-chain integrity
Lyophilized powder stored at −20°C and shipped with insulated packaging so the batch you receive matches the batch that was tested.
Peptide content & water
Net peptide content and residual moisture are reported so reconstitution math reflects the real mg in the vial.
Reject on fail
Batches that miss the ≥99% release spec are rejected outright rather than downgraded or blended into stock.
Requesting your COA in three steps
- 1
Read the LOT code
It's printed on the vial label and shown on the product page for the batch currently in stock.
- 2
Send it to us
Message the compound, mg size and LOT code on WhatsApp or live chat — no account or ticket needed.
- 3
Get the report
We return the third-party chromatogram and MS report for that batch, usually the same business day.
