Manufacturer / brand review
LifeTein documents standard identity/purity checks and explicitly separates additional content analysis.
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 QC is HPLC and MS; RP-HPLC purification is described. Net peptide content, amino-acid and elemental analysis are additional options.
How often is testing performed?
HPLC/MS data are described as part of peptide orders. No dated batch series or calendar retesting interval established.
What remains unverified
Gross powder mass cannot substitute for net peptide content. No product-specific endotoxin, sterility or solvent results 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.
