How we verify providers
A provider appears in the PeptideAgent directory only after we check it against four public criteria and record the date. Two are required to be listed at all: an active license in every state served, and no research use only sales. The other two, 503A or 503B status and pricing transparency, are shown on every listing so you can compare.
The checklist
State licenseRequired to be listed
The pharmacy, clinic, or telehealth prescriber holds an active license or registration in every state it serves, including a nonresident pharmacy permit where the destination state requires one.
How we check: We look up each license number on the issuing state board's public license search and record the numbers on the listing.
503A or 503B status
A compounding pharmacy states whether it operates as a 503A pharmacy (patient-specific prescriptions under a state license) or a 503B outsourcing facility (registered with FDA). Clinics and telehealth providers name the licensed pharmacy that fills their prescriptions.
How we check: We confirm 503B claims against FDA's outsourcing facility information and 503A claims against the state pharmacy license.
Pricing transparency
Prices, or a clear price range, for the peptides offered are published before checkout or consultation, including consult and membership fees.
How we check: We read the provider's public pricing pages and note what is and is not published.
No research use only salesRequired to be listed
The provider does not sell peptides labeled "research use only" or "not for human consumption" to consumers. Every product is dispensed on a prescription.
How we check: We review the provider's storefront and product pages for research use only products or disclaimers.
Why these four checks
Federal law lets a licensed pharmacy compound a drug for an individual patient under section 503A, and lets an outsourcing facility registered with FDA compound under section 503B with federal quality oversight. [1] [2] A compounded drug is not FDA approved, so the license and the compounding pathway are the main public signals of who is accountable for it. [3]
Peptides sold as "research use only" for people to inject are unapproved new drugs under the Federal Food, Drug, and Cosmetic Act, and FDA has issued warning letters to sellers. [4] [5] [6] A provider that sells them fails verification regardless of any other credential.
Pricing transparency is not a legal requirement. We record whether prices, including consult and membership fees, are published before you pay, so listings can be compared on the same terms.
What the labels on a listing mean
- Verified: Verified Sep 22, 2026
- The date PeptideAgent last completed the checklist for this listing. If a license lapses or a check fails, the listing is removed rather than marked down.
- Sponsored: Sponsored
- The provider pays for placement. Sponsored listings pass the same checklist, are ranked after unsponsored verified listings, and link out with a sponsored link attribute. Payment never changes an evidence grade, a regulatory status, or an agent answer.
Check a provider yourself
- Find the state board of pharmacy for the state you live in on your state's legal page and search its license lookup for the pharmacy that will ship to you.
- For a 503B outsourcing facility, confirm it appears in FDA's outsourcing facility information. [2]
- Search FDA's warning letter database for the company name. [6]
- Walk away from any seller that labels a product "research use only" or "not for human consumption".
Report a listing or apply
If a listed provider no longer meets a check, email hello@peptideagent.ai and we will re-verify it. Pharmacies, clinics, and telehealth providers can apply for a listing.
