Peptides are short chains of amino acids — the same building blocks that make up proteins. They occur naturally throughout the body and play a critical role in signaling between cells, regulating hormones, supporting tissue function, and much more. Because of their targeted biological activity and high specificity, peptides are a popular subject of study in scientific and pharmaceutical research. Petratide Science provides synthetic peptides manufactured to strict purity standards for use in controlled laboratory environments.

All products sold by Petratide Science are designated Research Use Only (RUO). This means they are intended exclusively for in vitro (laboratory) and pre-clinical scientific research — not for human or veterinary consumption, clinical trials, or diagnostic use. By purchasing from Petratide Science you confirm that you are a qualified researcher and that all materials will be handled in a controlled laboratory setting in compliance with applicable laws and regulations.

Yes. Every product comes with a third-party Certificate of Analysis (COA) confirming purity, identity, and batch-specific test results. COAs are available directly on each product page via our COA library and can be downloaded at any time. If you need a COA for a specific batch or have questions about a test result, our support team is happy to assist.

Proper storage is essential to maintaining peptide integrity. As a general guideline, lyophilized (freeze-dried) peptides should be stored at −20°C in a sealed, moisture-free environment and kept away from direct light. Once reconstituted, solutions should be aliquoted to avoid repeated freeze-thaw cycles and stored at −80°C when not in use. Specific storage recommendations for each product are noted on the product page and COA. When in doubt, colder and drier is better.
