Manufacturer / brand review
US Chem Labs describes analytical methods, but a representative product-specific report was not inspected.
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
Published HPLC/MS and COA claims coexist with analytical services including LC-MS/MS, quantity and stability. Selling testing services does not prove those tests were performed on every listed product.
How often is testing performed?
The site says documentation is available where available; small-batch freshness is not a measurable test frequency.
What remains unverified
Request a named lab, dated lot report and exact test coverage. The previously linked FDA warning remains separate from any finding about chemical purity.
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.
