Confirm any pharmacy yourself with primary-source, public lookups.
Check a pharmacy in about two minutes
A legitimate compounding pharmacy is state-licensed, dispenses only on a prescription, and
can prove its credentials. Here is how to confirm one yourself before you spend anything.
Make sure a prescriber is involved. A licensed clinician should evaluate you first.
No prescription and no medical oversight is a disqualifier.
Find its state pharmacy license. Every pharmacy is licensed by a state board you can
search. Confirm the license is active and in good standing.
Look it up on NABP's Safe Pharmacy tool. NABP flags online pharmacies as accredited
or "Not Recommended."
Check LegitScript certification. Google, Meta, Visa and Mastercard require it before a
pharmacy can advertise or take card payments.
Search FDA warning letters for the name. A recent enforcement action is a hard stop.
Prefer a .pharmacy web address. That domain is vetted by NABP and cannot be faked.
Demand a batch-matched Certificate of Analysis from an independent lab, showing HPLC
purity and sterility, with a lot number that matches the vial.
An "RUO" or "not for human consumption" label is a liability shield for the seller, not a
safety certificate and not a legal path to put something in your body. In 2026 the FDA explicitly rejected
that label as a defense, ruling that website evidence showed the products were intended as drugs. If a site
sells vials this way, that is the warning sign, not a loophole.
Red flags
Sells "research only" vials but describes human use, dosing, or benefits.
No prescription required and no clinician evaluates you.
Prices that seem too good to be true (a $10 to $15 vial of something that legitimately costs more).
Will not name the compounding pharmacy that fills your prescription.
No verifiable business address, no reachable licensed pharmacist.
A Certificate of Analysis with no lot number, no named lab, or one that does not match the vial.
