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.
FICTIONAL COA REVIEW / SAMPLE

TRACEABILITY MODERATE
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 TRANSPARENCY
Understand How Clearly Suppliers Present Pricing.
PSR evaluates pricing transparency and the context surrounding publicly displayed prices. Current reports do not provide standardized product-by-product price rankings.
PRICING TRANSPARENCY REVIEW
PUBLIC LIST PRICES
Whether public prices are clearly displayed.
QUANTITY OR VIAL SIZE
Whether product quantity or vial size is specified.
PROMOTION DISCLOSURE
Whether promotions are shown and identified as temporary.
SHIPPING INFORMATION
Whether shipping information is available to review.
INVENTORY OR AVAILABILITY STATUS
Whether inventory or availability status is visible.
Transparency Provides Context
PSR reviews how clearly suppliers present pricing information. A lower displayed price does not necessarily indicate better value, quality, or availability.
Pricing changes frequently.
Public prices, promotions, shipping information, and availability may change. Transparency findings reflect what PSR could verify at the time of review.

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.
