Scores reflect PSR’s review of publicly available and supplier-provided documentation and transparency indicators. They are not a determination of product safety, medical suitability, or regulatory approval.

TESTING & EVIDENCE REVIEW
A COA Is Only as Useful as the Evidence Behind It.
PSR reviews the quality, completeness, traceability, and credibility of supplier-provided analytical documentation so researchers can better understand what information is actually available.
ANALYTICAL TESTING
Review of available third-party or supplier-provided analytical testing documentation and the methods reported.
COA QUALITY
Evaluation of meaningful test details, dates, lot information, laboratory identification, and supporting data.
LOT TRACEABILITY
Assessment of whether records can be reasonably connected to a specific referenced lot or batch.
EVIDENCE TRANSPARENCY
Review of how clearly testing records and supporting information are presented and made available.

Documentation ≠ Verification
The existence of a COA alone does not establish product safety, identity, purity, regulatory compliance, or suitability for human use. PSR evaluates the quality and transparency of the documentation itself.

PRICING INTELLIGENCE
Compare the Price. Understand the Context.
PSR organizes supplier pricing alongside documentation, testing evidence, lot traceability, and transparency indicators so researchers can make more informed comparisons.

Lowest Price ≠ Best Value
PSR considers pricing alongside the quality and availability of supporting documentation. A lower listed price does not necessarily indicate better value, higher quality, or greater reliability.
Pricing changes frequently.
Supplier pricing, shipping costs, promotions, and availability may change. PSR reports should display the date pricing information was last reviewed.

PSR uses a structured review framework to evaluate the quality, availability, and traceability of supplier information. Scores reflect transparency and evidence quality — not product safety, efficacy, or medical suitability.
WEIGHTED REVIEW AREAS / 100% TOTAL
DOCUMENTATION QUALITY / 25%
Completeness, report clarity, dates and identifying information, plus supporting records.
TESTING EVIDENCE / 25%
Available analytical records, laboratory identification, reported methods, and supporting information.
LOT TRACEABILITY / 20%
Lot or batch identification, documentation connection, date context, and consistency.
PRICING TRANSPARENCY / 15%
Listed pricing, package quantity, comparable unit pricing, and cost visibility.
SUPPLIER TRANSPARENCY / 15%
Accessible supplier information, documentation availability, contacts, policies, and disclosures.

What the PSR Score Means
The PSR Transparency Score reflects the quality, availability, and traceability of information reviewed by PSR at the time of analysis.
What the PSR Score Does NOT Mean
A PSR score is not a certification, laboratory verification, medical recommendation, safety rating, regulatory approval, or guarantee of product quality.
Scores may change as suppliers update documentation, testing records, pricing, policies, or other information.
