Peptide Institute Review: Testing & Evidence Score

Manufacturer / brand review

Peptide Institute publishes detailed historical analytical sheets. The dated example demonstrates documentation format but has limited relevance to current stock.

Inspected sample results

KYT-36, code 4396-v, lot 640615, record 140375 dated 11 June 2014. The sheet provides elemental results and an HPLC method using a YMC ODS-A column, a 20–60% acetonitrile gradient and 220 nm detection. It is a historical peptidic-inhibitor record; no numeric peptide-content assay is reported.

Testing methods and purification

The inspected historical KYT-36 analytical sheet includes elemental analysis, TLC and an HPLC chromatogram/method. It concerns a peptidic inhibitor and does not cover present-day catalogue lots.

How often is testing performed?

One June 2014 lot record was inspected; this is historical evidence, not current batch coverage or an annual testing schedule.

What remains unverified

No current peptide lot certificate, measured net content or contaminant panel inspected. Historical data receive partial rather than current multi-lot credit.

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 guides Business decision guides our methodology.

Purity & identity5/20: historical HPLC and elemental/TLC documentation for a peptidic inhibitor; incomplete current peptide purity/identity evidence.5/20

Independent laboratoryNo inspected external-laboratory report earns credit; in-house QC is not independent testing.0/20

Contaminant controlsNo qualifying, product-specific contaminant result inspected. Optional capabilities do not earn result points.0/30

Quantity & traceability5/20: identifiable lot with a dated document (5); no measured peptide-content result earns quantity credit (0). A print or expiry date does not establish analysis timing.5/20

AccountabilityPublic business/contact and product-use context; no independent audit of the operator.5/10

Verification limits

Lab attribution: Peptide Institute in-house QC. 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.
