Manufacturer / brand review
GenScript documents a custom-peptide QC workflow; optional low-endotoxin services must be specified in the order.
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
Analytical HPLC and MS are described throughout synthesis and purification. TFA exchange and endotoxin control are additional services rather than universal standard tests.
How often is testing performed?
The quality policy describes testing all peptides; no sequence of dated customer lot certificates was inspected.
What remains unverified
No actual batch result or external laboratory report inspected. Request final-product content, residuals and the ordered endotoxin specification.
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.
