Peptides are short chains of amino acids that serve as signaling molecules in biological systems. In laboratory research, they are studied for their roles in cellular processes, protein interactions, metabolism, and other scientific applications. All products on this site are sold strictly for laboratory research purposes only.

No. All peptides and compounds listed are designated For Research Use Only (RUO). They are not intended for human consumption, therapeutic use, diagnostic purposes, or any form of medical treatment. They have not been evaluated or approved by the FDA for human use.

Reconstitution involves adding bacteriostatic water or another appropriate solvent to the lyophilized (freeze-dried) powder in the vial. The exact volume and method depend on the specific peptide and desired concentration for your experiment. Always follow standard laboratory protocols for solubility and handling. A dosing calculator tool is available on our site for educational/research reference only.

Most of our research peptides are tested to ≥98–99% purity via HPLC and mass spectrometry. We provide third-party Certificates of Analysis (COAs) from labs such as Janoshik where available. You can verify the unique key on the lab’s website for authenticity. Purity and testing details are listed on each product page.

Lyophilized (powder) peptides are generally stable when stored in a cool, dry place away from light. Once reconstituted, most should be refrigerated (2–8°C) and used within a short period according to standard lab guidelines. Avoid repeated freeze-thaw cycles. Specific storage recommendations are included with each product’s COA or description for research purposes.

Net peptide weight refers to the actual amount of pure peptide in the vial, while gross weight includes the peptide plus any counterions, salts, or residual moisture. Research vendors typically list both; always check the COA for precise net content when calculating concentrations for your experiments.

These questions cover the biggest pain points buyers ask about: legality/intent, quality, handling, and storage. They help build trust without crossing into medical advice.
