What Sermorelin Is
Sermorelin is a growth-hormone-releasing hormone analog that prompts your own pituitary to release growth hormone. It is taken as a nightly subcutaneous injection, and most people notice it in sleep in 2 weeks; composition in 2 to 3 months.
What Ipamorelin Is
Ipamorelin is a growth-hormone secretagogue that triggers a pulse without raising cortisol or appetite. It is taken as a nightly subcutaneous injection, and most people notice it in 2 weeks for sleep; months for composition.

Pick Sermorelin If
Your main concern is a gentle, well-studied growth-hormone starter. It is the right call when the goal is sleep, recovery and body composition and you want the simpler, more targeted option.
Pick Ipamorelin If
Your main concern is a selective growth-hormone pulse with minimal side effects. It is the right call when the goal is clean growth-hormone pulses.
Can You Combine Them?
Yes, though CJC-1295 is the more common partner for ipamorelin. Sermorelin plus ipamorelin works the same way: a GHRH analog plus a secretagogue.
