What to Check Before You Buy Research Peptides
A short pre-purchase checklist covering identity, documentation, labeling, and fulfillment.
Before you place an order, run through this short checklist. It takes a minute and protects your research.
Identity and quantity
Confirm the full compound name, labeled quantity, and format. Where available, check CAS and molecular-weight data. Remember that identity, purity and quantity are three separate measurements.
Documentation
Require a batch-linked Certificate of Analysis. On arrival, confirm the lot number on the vial matches the COA — the basis of batch traceability. Know what a COA does not prove.
Labeling
Verify the product is labeled research-use-only with no human-use or dosing claims. See research use only: what it means.
Fulfillment
Look for tracked U.S. shipping and protective packaging for lyophilized material. TagPep publishes delivery details by Georgia city.

Frequently asked questions
What should I check before buying research peptides?
Confirm the compound identity and quantity, require a batch-linked Certificate of Analysis with a matching lot number, verify research-use-only labeling, and check for tracked U.S. fulfillment. Products are not for human or veterinary use.
Why does the lot number matter?
Because a COA is only batch-specific when its lot number matches the vial received — otherwise the documentation does not describe your material.
