Manufacturer / brand review
PolyPeptide publishes a substantial GMP QC framework for contract manufacturing, rather than consumer-vial test results.
Inspected sample results
No product-specific laboratory result was inspected in this research pass. Published methods and service specifications are described below; they are not measured batch results.
Testing methods and purification
GMP analytical scope covers UHPLC purity/related substances, MS identity, content, counterions, moisture, residual TFA/solvents and microbial/endotoxin specifications. Published limits are specifications, not results.
How often is testing performed?
The QC documentation describes release against predetermined specifications for each lot. No current series of lot COAs or calendar retesting schedule was inspected.
What remains unverified
Confirm product, site, development phase and release specification. Do not apply provisional GMP specifications to all products or infer a passed contaminant panel.
Catalogue snapshot
Examples from the linked source, not a complete or real-time stock list. Institutional entries describe service categories. Shipping to Cyprus is not verified.
Why this score?
Points reward evidence maturity, not measured product purity. Claim-only points are limited; unknown criteria remain zero. Full rules are available in Research guidesBusiness decision guidesour methodology.
Verification limits
Lab attribution: Not verified. A laboratory-hosted record, where explicitly identified, was inspected on the lab’s portal. No direct staff confirmation, blind purchase, independent sampling or full current-batch audit was performed by Peptide.cy. Absence of a recorded test is not proof of contamination.
Public claims about purification cost, manufacturing location or certifications are not treated as proof of a clean final product. An authenticated COA would still apply only to its identified sample.
