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 DSIP Is
DSIP is delta sleep-inducing peptide, studied for slow-wave sleep. It is taken as a subcutaneous injection 30 to 60 minutes before bed, and most people notice it in nights to two weeks; some people do not respond.

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 DSIP If
Your main concern is broken or shallow sleep when melatonin has not helped. It is the right call when the goal is deeper sleep.
Can You Combine Them?
Yes. Sermorelin improves sleep as a side benefit of growth-hormone release; DSIP targets sleep directly. Some people use sermorelin nightly and add DSIP for a few weeks.
