Manufacturer / brand review
Thermo Fisher publishes a useful grade comparison; standard, high-throughput and quantitative reference peptides have different QC packages.
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
Custom-peptide QC differs by grade: standard services use MS/HPLC, Pepotec can use MS only, and AQUA grades include quantitative amino-acid analysis with grade-specific tolerances.
How often is testing performed?
The brochure describes analytical data delivered with orders, not a universal calendar retesting frequency.
What remains unverified
The brochure is a service specification, not an inspected lot COA. Instrument application notes are not evidence that each sold peptide passed those tests.
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.
