Manufacturer / brand review
CSBio provides a concrete purification case study, but it does not establish routine release results for other peptide orders.
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
A public long-peptide case study describes C18 HPLC purification from 75% crude to 98.7% purified material, with yield information. This is a process example, not a current commercial lot COA.
How often is testing performed?
No catalogue-wide batch testing or fixed retest schedule established from the inspected case study.
What remains unverified
Request product-specific identity, purity, content and residual analysis. Process yield and high chromatographic purity alone do not establish a contaminant-free product.
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.
