Documentation & Standards
Our testing protocols, COA library, and research guidelines — all in one place.
Testing Standards
HPLC Analysis
Every compound batch undergoes High-Performance Liquid Chromatography analysis by an independent third-party laboratory to verify purity, sequence identity, and absence of contaminants.
Third-Party Only
We do not accept in-house testing. All analytical results must come from accredited external laboratories with documented chain-of-custody and calibration records.
Batch Documentation
Every batch ships with a batch number traceable to its COA. We retain records for a minimum of 3 years and make them available on request.
COA Library
Batch-specific COA documents are available upon request. Contact us with your order number.
Frequently Asked Questions
What does 'research use only' mean?
All compounds sold by True Test Peptides are intended solely for in vitro laboratory research. They are not approved, tested, or safe for human consumption, injection, or any clinical or veterinary use.
How do I access the COA for a product?
Every product page links to its batch-specific Certificate of Analysis. You can also request a COA by contacting us with your batch number after purchase.
What is HPLC testing?
High-Performance Liquid Chromatography (HPLC) is the gold-standard analytical method for verifying peptide purity, identity, and concentration. We use third-party HPLC results — not in-house — for every batch.
How should I store research peptides?
Most lyophilized (freeze-dried) peptides should be stored at 2°C to 6°C and kept away from light. Long-term storage at -20°C is recommended. Always check the individual product COA for specific guidance.
Do you ship internationally?
We ship to select countries where research peptides are legal for import. It is the buyer's responsibility to confirm local regulations before ordering.
