Quality & testing

Every claim on this site has a document behind it.

Purity is easy to write on a label and hard to prove. This page explains exactly what we test, who tests it, and how you can pull the report for the vial in your hand.

⚖

Independent laboratories

Testing is commissioned from third-party analytical labs with no commercial interest in the result. We publish the issuing lab on the certificate.

▣

Lot-level traceability

Every vial carries a lot number. That number maps to one report — not to a generic sample from a previous production run.

❄

Cold chain, end to end

Material is stored at -20°C and dispatched in insulated packaging so that what leaves the freezer is what reaches the bench.

Specification

What we measure

HPLC purity
≥ 99%
High-performance liquid chromatography quantifies how much of the vial is the target peptide.
Mass spectrometry
Identity confirmed
Molecular weight is matched against the theoretical mass of the sequence.
Appearance
White lyophilised powder
Visual inspection of the cake and closure integrity before release.
Water content
Karl Fischer
Residual moisture is measured because it drives long-term stability.
Storage
-20°C, protected from light
Held and shipped cold from our Miami facility.
Certificates describe the chemical characteristics of a laboratory material. They are not a statement of safety or efficacy in humans, and they do not imply approval by any regulatory body.
