Peptides are short chains of amino acids, the same building blocks that form proteins. In research, they're studied for their roles in cell signaling, biological pathways, and a wide range of targeted laboratory applications.

Certain peptide-based medications have received FDA approval for specific clinical uses, but the research peptides sold by Fine Research Peptides are not FDA approved and are not intended for human or animal use. Our products are supplied strictly for laboratory research purposes only. They are not sold as medicines, dietary supplements, cosmetics, or treatments for any condition. Researchers are responsible for reviewing all applicable regulations and product documentation before use.

Once reconstituted, peptides are typically kept refrigerated between 2-8°C for short-term laboratory use. Actual storage time can vary with the specific peptide, solvent, concentration, and handling conditions. Always follow supplier guidance, your institutional protocols, and the documentation provided, and never use any material that appears cloudy, discolored, contaminated, or otherwise compromised. Research use only.

Start with unopened, in-date bacteriostatic water and follow the manufacturer's storage instructions. Once opened or mixed, it's commonly used within 30 days in controlled laboratory settings. Discard the solution if it looks cloudy, discolored, or contaminated, or if sterility is ever in question. Always follow supplier instructions, institutional protocols, and applicable research guidelines.
