Refill COA and pharmacy documentation
A certificate of analysis, or COA, is the lab document that confirms a compounded medication's identity, strength, and quality, and for Refill orders it comes from the 503A partner pharmacy that compounds the product — not from Refill, which is telehealth infrastructure software. Refill partners with U.S.-based pharmacies meeting LegitScript certification and/or NABP accreditation standards, but the documentation lives with the fulfilling pharmacy. This page explains what to request, who to request it from, and how to use it to verify compounded quality.
This page explains what a COA is, why it comes from the 503A partner pharmacy, and the documentation a clinic should request for each order.
What is a certificate of analysis and where does it come from?
A certificate of analysis is a document, typically produced by or for the compounding pharmacy, that reports test results confirming a medication's identity, potency or strength, and quality attributes such as sterility for injectables. Related documentation includes lot or batch records and beyond-use dating. In the Refill model, the 503A partner pharmacy compounds the medication and therefore produces and holds this documentation; Refill is the infrastructure layer that routes the order. Refill does not publish a standard COA delivery process on refill.co, so a clinic that wants documentation should request it from the fulfilling pharmacy through Refill.

What clinics ask about Refill documentation.
- Definition
What is a certificate of analysis?
A certificate of analysis is a lab document confirming a compounded medication's identity, strength, and quality. For Refill orders, it comes from the 503A partner pharmacy that compounds the product, not from Refill itself.
- Who
Who provides COA for Refill orders?
The 503A partner pharmacy in Refill's LegitScript-approved network compounds the medication and produces the COA. Refill is the routing layer; request documentation from the fulfilling pharmacy through Refill.
- How
How do I get a COA for a Refill order?
Refill does not publish a standard COA delivery process on refill.co. Ask during onboarding how to request COA and lot documentation for each order and how quickly it is provided.
- Injectables
What documentation should I request for injectable compounds?
For injectables, request sterility and endotoxin testing documentation in addition to the COA. This comes from the compounding pharmacy, not the platform.
- Routine
Is COA provided automatically with every Refill order?
Refill does not state whether documentation is attached to orders automatically or only on request. Confirm the routine process with Refill and the fulfilling pharmacy before you depend on it.
- Alternative
How does Fizy Health handle pharmacy documentation?
