Protocol Schedule Builder

Injection timing depends on the peptide's mechanism and half-life. Growth hormone secretagogues like Ipamorelin and CJC-1295 are typically administered before bed to align with the body's natural nocturnal GH pulse, or in the morning on an empty stomach. GLP-1 agonists like semaglutide are dosed weekly on a consistent day. BPC-157 can be taken any time but is often split into two daily doses for more stable serum levels. Consistency in timing matters more than the exact hour -- choose a schedule you can maintain reliably throughout your protocol.

For growth hormone secretagogues (Ipamorelin, GHRP-2, CJC-1295, Sermorelin), fasting for at least 30 minutes before and after injection is strongly recommended. Food intake -- especially carbohydrates and fats -- causes insulin and blood glucose spikes that blunt GH release and can reduce the peptide's effectiveness by up to 50%. For other peptides like BPC-157 and TB-500, food timing has minimal impact on efficacy since they work through different mechanisms. GLP-1 agonists like semaglutide can be administered regardless of meal timing.

Some peptides can be drawn into the same syringe for a single injection, but this depends on chemical compatibility. Ipamorelin and CJC-1295 are commonly combined in one syringe without stability issues. BPC-157 and TB-500 can also be mixed in the same syringe. However, peptides should never be stored mixed in the same vial long-term, as this can cause degradation. Always draw each peptide from its own vial into the syringe immediately before injection. When in doubt, administer peptides as separate injections at different sites to ensure full bioavailability.
