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.
What gets scored.
Named human owner or registered legal entity. Hidden ownership, offshore shell, or unresponsive admin = 0. Public license number and real address = 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.
Certificate of Analysis per lot, third-party tested. No COA = 0. First-party only = 1. Third-party (Janoshik, Anresco, etc.) per lot = 3.
Lot number, expiry, storage temp on every unit. Tamper-evident. Anti-counterfeit seal where possible.
Tracked, insured, temperature-logged where relevant. Transit time within SOP. Customs declaration accurate to content.
Pre-sale inquiry handled within 24 hours by a named human. Post-sale support handled within 48 hours. Ghost-after-payment = 0.
Independent review sources (Reddit, Trustpilot, community forums) cross-referenced. Forensic check for fake-review patterns.
Published policy for broken vial, wrong product, dud lot. Refund or replacement SLA in writing.
Inside the sane band for the compound and channel. Dramatically cheaper than peers = suspicious, not good.
No fake scarcity countdowns, no weight-loss velocity claims, no 'lose 30 lbs in 30 days.' FTC compliance is a baseline, not a win.
Domain age, business registration date, continuity of trading name. Not a hard filter (new vendors can be good), just a signal.
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.
- 1FDA warning letter, DEA action, or documented regulatory enforcement
- 2Criminal conviction tied to the vendor or its named principals
- 3Verified counterfeit or mislabeled product (lab-confirmed, not rumor)
- 4Permanent closure (site dead more than 90 days + no owner response)
- 5Systematic fake-review patterns (forensically confirmed, not inferred)
- 6Vendor refused COA request more than twice without credible reason
- 7Vendor ghosts payment for 30+ days and no refund
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.
