FAQ

Peptides are short chains of amino acids that act as building blocks of proteins.

Please use the BAC Water Calculator to determine how much bacteriostatic water to add to your peptide.

Check out our reconstitution guide, or use the Peptide Calculator to get exact draw amounts for your syringe.

Lyophilized peptides are stable for months when frozen. Once reconstituted, refrigerate and use within the timeframe noted on your COA.

Store lyophilized vials in a freezer for long-term stability. After reconstitution, keep refrigerated and protected from light.

We provide peptides for research purposes only and do not give out any medical advice. Please conduct independent research or speak to a licensed medical professional.

Our peptides are lyophilized (freeze dried) for shelf stability during shipping and handling, to ensure they arrive at maximum potency. They require bacteriostatic water for research use.

All of our peptides are sourced from vetted, quality-controlled synthesis partners with documented manufacturing standards.

Vytal Peptides uses independent third-party laboratories to provide analytical testing for research materials. Testing methods and reported specifications may vary by compound and batch, so researchers should review the applicable Certificate of Analysis for specific results.

Current Certificates of Analysis can be viewed on our Testing page and, where available, directly from the corresponding product page. Match the batch or lot number on your research material with the number shown on the applicable COA.

A reported purity percentage describes the proportion of material attributed to the target compound using the analytical method identified in the report.Purity should not be interpreted as confirmation of sterility, endotoxin levels, biological activity, stability, or suitability for human or veterinary use unless those characteristics were separately tested and specifically documented.

Depending on the product and batch, additional analytical documentation may include identity, endotoxin, microbial, residual solvent, or other testing. Researchers should rely on the specific tests and results shown on the applicable batch documentation rather than assuming that every test has been performed on every product.
