Every provider is scored the same way.
The full listing score is published — every component, out of 100.
Providers are ordered by a listing score computed in our database. Manual review is its largest component, and the methodology page states exactly what each point rewards — and what the score cannot tell you.

Refresh runs on manual dispatch
One email when a compound's median $/mg moves — nothing else. It only fires on a price change.
Median $/mg · read from vendor storefront APIs · high-confidence research vendor data only · not clinical pricing · verify directly with vendors · trend line: median of the prices that changed that day, not the whole market
Start from an outcome, not a compound.
Each goal maps to the peptides researchers study for it and the providers who carry them.

Work the literature, not the marketing.
Every compound graded by research maturity — four tiers reflect how much published literature exists, not whether a compound works.

extensive literature
Most compounds sit in the early tiers — that skew is honest, and it's exactly why we grade them.

Five questions we get every week. Short answers — longer explanations live in the methodology page.

No. PeptideBase is an educational directory and matching tool. We aggregate publicly available information about providers and compounds. Nothing on the platform is a prescription, treatment plan, or substitute for consultation with a licensed clinician.
No. Provider rankings are determined by an algorithmic scoring system — 0 paid placements.
Clinics employ licensed practitioners who can prescribe. Compounding pharmacies (503A / 503B) formulate and dispense against a prescription. Vendors sell compounds for research use only — no prescription, no medical guidance, and not for human consumption.
A small number — Semaglutide and Tirzepatide among them — are FDA-approved for specific indications. Most peptides catalogued on PeptideBase are not FDA-approved and are dispensed under compounding exemptions or sold for research. Each peptide page lists its current regulatory status.
The quiz runs entirely client-side. No account is required to receive a match. We log aggregate, anonymized response distributions to improve the matching model — never tied to an identity. You can review the data we collect on our privacy page.
