Every batch, 7× tested.
No in-house rubber stamps. Seven separate analytical checks, performed by accredited U.S. laboratories, signed onto the Certificate of Analysis tied to every lot we ship.
- 01Pass
Purity
HPLC-UV quantification against certified reference material.
- 02Pass
Content Verification
Mass and concentration verified to labeled potency.
- 03Pass
Identity Confirmation
Mass spectrometry confirms exact molecular structure.
- 04Pass
Heavy Metals Screening
ICP-MS screen for Pb, As, Cd, Hg below USP <232> limits.
- 05Pass
Sterility Testing
USP <71> compliant sterility screen on every fill.
- 06Pass
Endotoxin Testing
LAL kinetic chromogenic assay, < 0.5 EU/mg.
- 07Pass
Batch Conformity Verification
Independent batch review confirming every lot matches its release specification and COA.

A higher standard, documented end-to-end.
Most research suppliers ask for trust. We hand you the proof.
Seven-stage testing
Purity, content, identity, heavy metals, sterility, endotoxin and batch conformity — every lot, no exceptions.
Transparent documentation
Every order arrives with its batch-specific Certificate of Analysis, available on every product page.
U.S. accredited laboratories
Every lot is analysed by accredited U.S. labs via HPLC and mass spectrometry before release.
Independent verification
The lab that measures the material is never the lab that made it. If a batch fails, it does not ship.
Seven stages before a vial leaves the building.
A documented, repeatable verification pipeline applied to every single lot.
01
Purity (HPLC-UV)
Quantified against certified reference material.
02
Content Verification
Mass and concentration verified to labeled potency.
03
Identity (MS)
Mass spectrometry confirms exact molecular structure.
04
Heavy Metals
ICP-MS screen for Pb, As, Cd, Hg below USP <232> limits.
05
Sterility
USP <71> compliant sterility screen on every fill.
06
Endotoxin
LAL kinetic chromogenic assay, < 0.5 EU/mg.
07
Batch Conformity
Independent review against the release spec, then the COA is published.
Look up any batch. Read every result.
Type any lot number from a Peptyx Labs vial to pull the full certificate of analysis — purity, identity, molecular weight and sequence confirmation, signed by the testing laboratory.
- Independent third-party laboratory
- Signed digital COA per lot
- Public batch verification portal
- Permanent record retention
