Peptide ScheduleGrowth Hormone Peptides
GHRH analogs, GH secretagogues, and synthetic HGH for growth hormone optimization.
Growth hormone peptides stimulate your body's natural GH production instead of injecting synthetic HGH directly. They work through two main pathways: GHRH (growth hormone releasing hormone) analogs and GH secretagogues that trigger pulsatile release.
The most popular combo is CJC-1295 paired with Ipamorelin. CJC-1295 extends the GH pulse while Ipamorelin triggers it cleanly — without the cortisol or prolactin spikes you'd get from GHRP-6 or GHRP-2. MK-677 (Ibutamoren) is the oral option if you'd rather not inject.
Dosing frequency varies. CJC-1295 with DAC only needs 1-2 injections per week thanks to its long half-life. The no-DAC version requires daily injections. Most protocols call for evening dosing to align with your natural GH pulse during sleep.
