In GLP-1 therapy, the difference between a great patient outcome and a potential compliance issue often comes down to one thing: quality assurance.
A Certificate of Analysis (COA) is your proof that the medication you’re prescribing meets strict quality standards, and it’s one of the most essential safeguards in modern compounding and clinical supply.
Yet, not all providers receive or request COAs from their suppliers, and that’s a risk no clinic should take.
What Is a COA?
A COA is an official document generated by an accredited laboratory that verifies the:
Identity – Confirms the medication matches its label claim.
Potency – Verifies the concentration of active ingredients.
Purity – Ensures the product is free from harmful contaminants.
Composition – Validates excipients and inactive components.
Compliance – Confirms adherence to established quality specifications.
It’s essentially the “lab report” for your medication — and it’s your first line of defense in verifying that every dose is both safe and effective.
Why COAs Are Critical for GLP-1 Providers
1. Regulatory Compliance
State pharmacy boards and the FDA expect providers to source medications from compliant, licensed entities. Maintaining COAs demonstrates due diligence and can protect your practice during audits or inspections.
2. Quality Assurance
A COA confirms that the medication’s potency falls within the acceptable range — helping avoid underdosing, overdosing, or variability between shipments.
3. Patient Safety
By screening for contaminants and verifying purity, COAs help safeguard patients against adverse events caused by substandard medications.
4. Continuity of Care
Consistency matters in GLP-1 therapy. Using lots with verified specifications ensures that your patients receive the same quality medication throughout their treatment plan.
5. Risk Mitigation
Without a COA, you’re essentially relying on trust alone. In the event of a regulatory inquiry or patient concern, documented proof of quality is invaluable.
What to Look for in a COA
Not all COAs are equal. As a provider, make sure your supplier’s COA includes:
Batch or Lot Number matching the product you received
Date of Testing
Testing Parameters (identity, potency, microbial limits, heavy metals, etc.)
Pass/Fail Results for each parameter
Name of Testing Lab with accreditation details
