Manufacturer / brand review
JPT provides unusually specific grade-dependent testing rules. The FastGrade sampling exception matters when comparing prices and documentation.
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
QC varies by grade: most peptides receive individual HPLC/MS, whereas FastGrade uses statistical 5% testing. Premium PepMix describes LAL/rFC endotoxins, pharmacopoeial sterility and cytotoxicity testing.
How often is testing performed?
Most grades: each peptide. FastGrade: 5% sample. Premium PepMix: each batch, plus recurrent functional testing; no fixed interval is stated for recurrence.
What remains unverified
No actual Premium batch certificate inspected. Extra microbiological tests do not automatically apply to ordinary custom or FastGrade orders.
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.
