Manufacturer / brand review
ProteoGenix clearly separates standard custom-peptide analytics from optional quantitative and contaminant tests.
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
Standard custom COAs include HPLC/MS except crude/desalted grades. Gross weight is distinguished from optional net content; additional options cover AAA, water, counterions, solvents and endotoxins.
How often is testing performed?
Standard orders receive analytical documentation with stated grade exceptions; no dated lot series or fixed retest interval inspected.
What remains unverified
Do not transfer antibody quality-charter tests to peptides. No actual peptide lot COA or independent laboratory result inspected.
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.
