Peptides are short chains of amino acids โ€” think of them as smaller versions of proteins. Your body already makes thousands of them. They act as signaling molecules, telling your cells what to do. Research peptides are synthetic versions of these natural compounds, used in lab settings to study their effects on various biological processes. ## Why People Research Them The most commonly studied peptides fall into a few categories: - **Growth Hormone Secretagogues** (CJC-1295, Ipamorelin, MK-677) โ€” stimulate natural GH release - **Healing & Recovery** (BPC-157, TB-500) โ€” studied for tissue repair properties - **Metabolic** (Semaglutide, Tirzepatide) โ€” GLP-1 receptor agonists studied for metabolic effects - **Cognitive** (Semax, Selank, Dihexa) โ€” nootropic peptides studied for cognitive effects ## The Golden Rules 1. **Always check the COA.** If a vendor can't provide a Certificate of Analysis with HPLC purity โ‰ฅ98%, walk away. 2. **Learn to reconstitute properly.** Bacteriostatic water, insulin syringes, proper storage โ€” there's no shortcut here. 3. **Start low, go slow.** Research protocols typically begin at conservative amounts. 4. **Storage matters.** Most peptides need refrigeration after reconstitution. Some are fine lyophilized at room temp, but not all. 5. **Source matters.** The difference between a reputable vendor and a sketchy one is the difference between researching a real compound and researching mystery powder. ## Common Beginner Mistakes - Skipping the COA check (seriously, don't) - Using regular water instead of bacteriostatic water - Not rotating injection sites - Storing reconstituted peptides too long - Trusting vendors with no third-party testing ## Where to Go From Here Use our Reconstitution Calculator (https://www.bodyhackguide.co/tools/reconstitution) to get your math right, check vendor pricing on our Compare page (https://www.bodyhackguide.co/compare), and always verify your source with our COA Reader (https://www.bodyhackguide.co/tools/coa). ## Related Guides ๐Ÿ’‰ getting-started ### How to Reconstitute Peptides: Step-by-Step Guide The complete walkthrough for reconstituting lyophilized peptides with bacteriostatic water โ€” no guesswork needed.
