COA & lot tracking
Certificate of Analysis and lot tracking standards for research peptide orders
What qualified researchers should expect from lot documentation, what a COA can and cannot prove, and how Peptific handles documentation questions.
The short answer
Why lot-specific documentation matters
A COA should correspond to the actual lot being reviewed. Generic purity claims are weaker than documentation tied to the vial's lot identifier and the compound listed on the product page.
When evaluating a research-use-only peptide supplier, researchers should check that the product name, fill amount, lot ID, and available documentation do not conflict.
What researchers can request
Researchers may request the most recent available Certificate of Analysis before ordering. For shipped orders, researchers can request documentation tied to the lot ID on the vial or shipment record.
COA availability does not convert a research compound into a therapeutic, dietary, cosmetic, or human-use product. It is documentation for laboratory review.
How to read the limits of a COA
A COA can help assess identity, purity, and batch documentation. It is not an FDA approval, medical safety evaluation, clinical protocol, or guarantee of suitability for any non-research purpose.
Peptific does not provide dosing, administration, or clinical-use interpretation of analytical documents.
Damage, mismatch, or documentation issue
If a vial arrives broken, mislabeled, short of the listed fill amount, or materially inconsistent with the product page, contact support with the order number and a photo of the issue.
The replacement policy is designed for fulfillment errors and transit damage. Intact research compounds that have left controlled custody are not returned to sellable stock.
