Methodology

Eleven signals. One silent filter.

Every vendor in the Panya recommendation pool is scored against an 11-signal rubric. Each signal runs 0 to 3. The total is our Rubric Score. We also maintain a silent filter for vendors that fail catastrophically on specific traits. Silent-filtered vendors do not appear on the site. We do not name them. You do not know who did not make the list. That is the feature.

Panya earns a flat affiliate rate regardless of which vendor you pick. We do not get paid more for recommending a more expensive vendor or a higher-commission vendor. If the rubric says the cheaper option is better for your case, we say so.

The 11 signals

What gets scored.

Identity
Critical
0 to 3

Named human owner or registered legal entity. Hidden ownership, offshore shell, or unresponsive admin = 0. Public license number and real address = 3.

Cold-chain
Critical
0 to 3

For peptides requiring 2 to 8 degrees Celsius handling: documented chain of custody from manufacturer to user. No evidence = 0. Public SOP + photo evidence + refrigerated courier = 3.

COA / identity testing
High
0 to 3

Certificate of Analysis per lot, third-party tested. No COA = 0. First-party only = 1. Third-party (Janoshik, Anresco, etc.) per lot = 3.

Packaging and labeling
High
0 to 3

Lot number, expiry, storage temp on every unit. Tamper-evident. Anti-counterfeit seal where possible.

Shipping
High
0 to 3

Tracked, insured, temperature-logged where relevant. Transit time within SOP. Customs declaration accurate to content.

Response time
Medium
0 to 3

Pre-sale inquiry handled within 24 hours by a named human. Post-sale support handled within 48 hours. Ghost-after-payment = 0.

Review sentiment
Medium
0 to 3

Independent review sources (Reddit, Trustpilot, community forums) cross-referenced. Forensic check for fake-review patterns.

Returns
Medium
0 to 3

Published policy for broken vial, wrong product, dud lot. Refund or replacement SLA in writing.

Price
Low
0 to 3

Inside the sane band for the compound and channel. Dramatically cheaper than peers = suspicious, not good.

Promo behavior
Low
0 to 3

No fake scarcity countdowns, no weight-loss velocity claims, no 'lose 30 lbs in 30 days.' FTC compliance is a baseline, not a win.

Years in operation
Low
0 to 3

Domain age, business registration date, continuity of trading name. Not a hard filter (new vendors can be good), just a signal.

Silent filter

The seven triggers.

A vendor that triggers any of these is silently filtered. The vendor does not appear in match output. The Panya team does not name silent-filtered vendors in public. We do publish the trigger rules so you can trust the shape of the filter without having to trust a specific score.

  1. 1FDA warning letter, DEA action, or documented regulatory enforcement
  2. 2Criminal conviction tied to the vendor or its named principals
  3. 3Verified counterfeit or mislabeled product (lab-confirmed, not rumor)
  4. 4Permanent closure (site dead more than 90 days + no owner response)
  5. 5Systematic fake-review patterns (forensically confirmed, not inferred)
  6. 6Vendor refused COA request more than twice without credible reason
  7. 7Vendor ghosts payment for 30+ days and no refund
Dispute a score

Are we wrong about your vendor?

If you run a vendor and believe your Rubric Score is wrong, send evidence to partner@panya.health. We re-score on evidence, not on volume. Pay-to-rank does not exist here. If a silent filter fired on your vendor and you have proof the trigger was wrong, the same address is where the dispute lands.

We earn a small commission when you buy through recommended vendors. That is how this stays free. Vendors rank by quality signals, not paid placement.
