Certificate of Analysis matched to your vial
From synthesis to your lab, in six controlled steps
U.S. Sourcing & Synthesis
Every peptide is synthesized in U.S. domestic facilities using controlled, traceable raw materials.
Independent HPLC Analysis
Each batch is sent to an accredited third-party lab for High-Performance Liquid Chromatography purity verification.
Mass Spectrometry ID
Mass-spec confirms molecular identity and weight so you know exactly what is in every vial.
Batch-Level COA
A Certificate of Analysis is generated per lot and matched to the batch number printed on your vial.
Lyophilization & Sealing
Products are lyophilized, sealed, and labeled with lot and expiry under quality-controlled conditions.
Final Release Check
No batch ships until purity clears our 99% threshold and documentation is verified and published.
Every claim is documented
Every report is backed by independent third-party laboratory data. Look up any batch number and download its full Certificate of Analysis before you buy.

Quality, Answered
How do you verify 99% purity?
Every batch undergoes High-Performance Liquid Chromatography (HPLC) for purity quantification and Mass Spectrometry (MS) for identity confirmation at an independent, accredited third-party laboratory. Results are published as a batch-specific Certificate of Analysis.
What is a Certificate of Analysis (COA)?
A COA is a document from an independent laboratory that reports the measured purity, molecular identity, and quality parameters of a specific production batch. Our COAs are matched to the lot number on your vial and are downloadable from every product page and the COA Library.
Where are your peptides manufactured?
All peptides are synthesized in the United States using traceable raw materials, then tested by independent U.S.-based laboratories before release.
Do you test every batch or just samples?
Every production batch is tested, not a periodic sample. No lot is released for sale until it clears our 99% purity threshold and its documentation is verified.
Are these products for human consumption?
All products are intended strictly for in-vitro laboratory research and development use only. Not for human or veterinary use, not a drug, food, or cosmetic, and not intended to diagnose, treat, cure, or prevent any disease.
