PeakLifeRx 503B compliance: FDA registration vs LegitScript
PeakLifeRx routes clinic orders to FDA-registered 503B outsourcing facilities operating under cGMP production standards, with alignment to USP guidelines. This is a different compliance framework than the LegitScript certification that applies to 503A patient-specific compounding pharmacies. LegitScript certification is a third-party program that vets pharmacies against legal and safety standards, and 503A refers to the section of federal law governing patient-specific compounding. Because compliance lives with the fulfilling pharmacy, verifying each named partner is the step that actually confirms the medications are made under proper oversight.
This page explains what LegitScript and 503A mean, which party holds them in the PeakLifeRx model, and how to verify partner compliance.

What is the difference between 503B FDA registration and 503A LegitScript?
Two separate regulatory tracks govern compounded medications. The 503A track covers traditional, patient-specific compounding by state-licensed pharmacies; these pharmacies can earn LegitScript certification as an additional trust signal. The 503B track covers outsourcing facilities that manufacture bulk compounded products under FDA oversight and cGMP production standards; these are registered with the FDA and do not use LegitScript certification as their primary credential. PeakLifeRx works exclusively with the 503B track: FDA-registered outsourcing facilities under cGMP and USP standards. Fizy Health works on the 503A track: LegitScript-certified patient-specific compounders.

What clinics ask about PeakLifeRx compliance.
- Definition
Is PeakLifeRx LegitScript certified or FDA-registered?
PeakLifeRx routes to FDA-registered 503B outsourcing facilities, but the FDA registration is held by the 503B facilities, not the platform. To verify, ask which facilities fill your orders and confirm each one's current FDA registration at fda.gov.
- 503A
What does 503B mean?
503B is the section of federal law that governs outsourcing facilities — establishments that manufacture compounded products in bulk under FDA oversight and cGMP standards. It is distinct from 503A, which covers traditional patient-specific compounding by state-licensed pharmacies.
- Who
Does PeakLifeRx hold the pharmacy license?
No. PeakLifeRx is the ordering software; the FDA-registered 503B outsourcing facilities hold the regulatory registrations and perform the manufacturing. Compliance verification therefore happens at the 503B facility level.
- Verify
How do I verify a 503A pharmacy's compliance?
Confirm the facility's current FDA registration number at fda.gov/drugs/pharmaceutical-quality-resources, review any FDA 483 observations in its inspection history, and request certificates of analysis and lot documentation for your orders.
- Documentation
Can I get a certificate of analysis for PeakLifeRx orders?
PeakLifeRx's FAQ states COA and batch-level documentation are available on request from its 503B partners. Ask PeakLifeRx and the fulfilling 503B facility how to obtain COA and lot documentation for each order.
