How PeptideBase Verifies Providers

PeptideBase has indexed 3,136 providers across 8 countries — 2,500+ are publicly listed in the directory, with the remainder pending listing review. 75.8% of indexed providers — 2,376 — carry a verified badge. This post explains exactly what that means: what we check, what we don't, and why the distinction matters when you're evaluating providers in a market that ranges from licensed compounding pharmacies to gray-market research vendors.

What "verified" actually means

The verified badge on a PeptideBase provider profile answers a narrow, specific question: is this listing accurate?

Not "is this the best provider." Not "is this provider the right fit for your situation." The verification process does not make clinical judgments. It confirms that the provider is what it says it is, that it is currently operating, and that the information in the listing — location, provider type, telehealth availability, compound catalog — matches what the provider publicly offers.

This distinction matters because the alternatives are worse. A directory that implies quality endorsement without the clinical expertise to back it creates misleading signal. A directory with no quality signal at all is just a list. The verified badge is a defined, scoped signal — narrow by design, and honest about its limits.

What we check on every listing

Active status

The first check is whether the provider is currently operating. We verify this by:

• Confirming the provider's website is live and consistent with the listing
• Checking for any public notice of closure, license suspension, or operational pause
• For pharmacies, cross-referencing state board of pharmacy records where the license number is publicly available

A provider whose website is offline, whose contact information returns errors, or whose state license has lapsed receives a site_offline or program_suspended listing status and is removed from active directory results. As of May 2026, 39 providers carry these inactive statuses following our compliance audit — they are not visible in default directory searches.

Provider type accuracy

We check that the provider type in the listing matches what the provider actually is:

• A listed 503A compounding pharmacy should be licensed with its state board of pharmacy. We check the state board license lookup for the provider's state.
• A listed telehealth platform should have identifiable licensed prescribers and a visible clinical intake process — not just a product catalog.
• An online vendor listed as a research vendor should not be making explicit prescription drug claims in its primary marketing.

Type misclassification is a meaningful integrity issue. It affects how the directory is filtered and what expectations a user brings to the listing. A clinic listed as a pharmacy creates a false signal about licensing and oversight.

Location and contact accuracy

We verify that city, state/region, and country match the provider's actual location, using the provider's website and any publicly listed business registration information. Telehealth providers who serve multiple states are marked telehealth_available: true — but their listed location reflects the business entity's physical base, not the states they serve.

Compound associations

We check that the compounds listed for a provider are consistent with their public offerings — explicitly listed on their site or confirmed through their service catalog. We do not independently test compounds for purity. For guidance on evaluating lab testing documentation from research vendors, see our guide on CoA and HPLC testing.

What we don't check

Clinical quality. We do not evaluate prescribing practices, clinical protocols, patient outcomes, or whether specific practitioners are competent to prescribe the compounds they offer. This is outside the scope of a directory verification process.

Compound purity and testing. We do not test compounds for purity, sterility, or label accuracy. Verification that a vendor offers HPLC-tested compounds is based on what the vendor publicly claims — we do not commission independent testing.

Pricing accuracy. Pricing changes frequently and varies by patient situation. We list price tier as a rough indicator (budget / mid / premium) where available, but do not verify specific pricing.

Insurance or coverage. We do not check what insurance plans cover any provider's services. Coverage for compounded and non-approved compounds is limited and varies widely.

Patient reviews. We surface review counts and ratings from third-party sources (Google, Trustpilot) where publicly available, but we do not independently verify the authenticity or accuracy of individual reviews.

Verification rates by provider type

How the verified badge appears in the directory

A provider with the verified badge has passed the full check described above. The badge appears on:

• Provider profile pages
• Directory listing cards
• Match results

Providers without the badge are in the directory but have not yet been through the full verification check. They are not actively flagged as problematic — the absence of a badge means verification is pending, not that there is a known problem. The directory currently has 760 unverified listings. We process re-verifications on a rolling basis.

The compliance type field

For pharmacy providers, a compliance_type field appears on the profile:

• 503A: Licensed as a patient-specific compounding pharmacy under state board oversight
• 503B: Registered with the FDA as an outsourcing facility with higher manufacturing standards
• Unknown: We have not been able to confirm the compliance classification for this provider

982 providers in the directory carry a 503A designation. The compliance type is confirmed against state board license lookup records or the FDA's registered outsourcing facility list.

How we re-verify over time

Initial verification happens when a provider is added to the directory. Re-verification runs on a rolling cadence — every active provider is re-checked at minimum annually. High-priority providers — those with the verified badge, high user engagement, or featured placement — are re-checked more frequently.

The last_verified_at field on every provider profile shows when we last confirmed the listing. Providers can trigger expedited re-verification by claiming their listing at claim your listing, which allows them to update information directly and flag changes for review.

Why inactive providers stay in the database

Providers with site_offline or program_suspended status are excluded from active directory search results. They remain in the database for two reasons:

1. Historical completeness. A provider that was active and verified for two years provides useful historical signal — its absence from search results communicates something meaningful.
2. Recovery cases. Providers sometimes go offline temporarily. Keeping the record allows re-activation if the provider resumes operations and requests re-verification.

Users searching the directory will not see inactive providers unless they specifically filter for them.

How to flag an inaccurate listing

If you find a listing that appears inaccurate — wrong location, closed site, wrong provider type — use the "Report an issue" link on the provider profile page. All reports are reviewed within 7 days.

Providers can update their own information through claim your listing, which triggers a re-verification check.

What a verified badge doesn't guarantee

A verified badge on a PeptideBase listing means the provider is what it claims to be, is currently active, and has accurate listing information. It does not mean:

• The provider is the right choice for your specific situation
• The compounds they offer are appropriate for you
• Their prescribing or compounding practices meet any particular clinical standard
• They are licensed to serve you in your state

The decision to work with any healthcare provider requires your own due diligence. Use the directory to identify candidates — then verify their credentials, check their licensing in your state, and consult a licensed healthcare provider before making any clinical decisions.

Frequently asked questions

QWhat does the verified badge actually mean?

It means PeptideBase has confirmed that the provider is what it claims to be (correct type, correct location), that it is currently active, and that its listing information is accurate. Verification is a factual accuracy check — not a clinical quality assessment or endorsement of one provider over another.

QDoes a verified badge mean the provider is licensed?

For pharmacy providers, our verification process checks state board of pharmacy records where available. For clinics and telehealth platforms, we confirm that licensed prescribers are identifiable. Licensing requirements vary by state and change over time — always verify a provider's current licensing status directly with the relevant state board before making any clinical decisions.

QWhat happens if I find an error in a listing?

Use the "Report an issue" link on the provider's profile page. All reports are reviewed within 7 days. If you are the provider, use claim your listing to submit changes and trigger a re-verification.

QWhy are some providers listed without a verified badge?

The directory includes providers that have not yet been through the full verification check — typically because they were added from public data sources before our verification team reviewed them. The absence of a badge signals pending verification, not a known problem. We process verifications on a rolling basis.

QHow is this different from a pay-to-play directory?

Rankings in the PeptideBase directory are determined by the pb_score algorithm — a composite of verification status, data completeness, active listing status, and other editorial criteria. Provider listings are not ranked based on payment. Any featured or promoted placements are disclosed. The full scoring methodology is at /methodology.
