What purity level do your peptides achieve?
All of our peptides are produced to a minimum purity of 99.9% as verified by independent HPLC and mass spectrometry analysis. Exact purity for each batch is documented in the corresponding COA.
Are your products for human consumption?
No. All products are strictly intended for laboratory research purposes and are not for human or animal consumption. By purchasing from us, you agree to comply with all applicable laws and regulations in your jurisdiction.
Can I request a custom formulation or blend?
Yes. For institutional partners and B2B accounts we offer custom formulations, specific concentrations, and proprietary blends. Contact our team to discuss your requirements.
Testing & COA
How are your products tested?
Every production batch is independently tested using High-Performance Liquid Chromatography (HPLC) and mass spectrometry by a third-party laboratory. This ensures completely unbiased purity verification on every batch we ship.
Where can I access the Certificate of Analysis (COA)?
COAs are available for download on our COA page before you purchase. Every batch has a unique COA that documents purity, test date, lot number, and the results from independent analysis.
Is the testing truly third-party or done in-house?
Testing is performed by an independent third-party laboratory with no commercial relationship to Grey Peptides beyond testing services. This ensures impartiality and the highest standards of verification.

Storage
How should I store lyophilized peptides?
Lyophilized (freeze-dried) peptides should be stored in a cool, dry place away from direct light. For long-term storage, we recommend -20°C (freezer). Always refer to the specific COA documentation for compound-level storage recommendations.
What is the shelf life of your peptides?
When stored correctly (sealed, at -20°C), lyophilized peptides typically remain stable for 24 months or more. Shelf life varies by compound — check the individual product’s COA for the lot-specific expiry date.
