Peptides are short chains of amino acids that act as signaling molecules in your body. They tell your cells to do specific things, from healing tissue to releasing growth hormone to reducing inflammation.
Unlike hormones, most peptides are targeted. They tend to do one or two things well rather than having system-wide effects. This is why they have become popular in the optimization and research space. You can address specific goals without broad side effects.
Some of the most commonly researched peptides include BPC-157 (gut healing and tissue repair), GHK-Cu (skin and tissue regeneration), Ipamorelin (growth hormone release), and TB-500 (injury recovery and inflammation).
Peptides typically come as lyophilized (freeze-dried) powder in glass vials. Before use, they need to be reconstituted with bacteriostatic water. This process is simple but requires sterile technique to maintain purity and potency.
Dosing is measured in micrograms (mcg) or milligrams (mg). Most peptides are administered subcutaneously (under the skin) using an insulin syringe. The dose depends on the specific peptide, your bodyweight, and your goals.
Storage matters. Unreconstituted peptides should be kept in the freezer. Once reconstituted, they go in the refrigerator and are typically stable for 3 to 4 weeks. Never leave reconstituted peptides at room temperature.
If you are new to peptides, start by understanding the basics of reconstitution, dosing, and storage. Our Peptide Academy and Peptide Calculator are built to help you get this right from day one.
