Questions, answered.

What is Sermorelin?
Sermorelin is a growth-hormone-releasing hormone (GHRH) analog corresponding to the first 29 amino acids of GHRH, studied for its ability to stimulate the body's own growth-hormone production. It has a very short half-life. This entry is informational and is not a recommendation to use the compound.
What is Sermorelin's half-life?
Sermorelin's elimination half-life is approximately about 12 minutes, per published pharmacokinetic data. After about five half-lives (~1 hour), a single dose is roughly 97% eliminated. Individual clearance varies.
Is Sermorelin the same as GRF 1-29 or Sermorelin Acetate?
GRF 1-29 and Sermorelin Acetate are other names associated with Sermorelin.
What do people log alongside Sermorelin?
People tracking this compound often log injection-site tolerance, sleep, and recovery-related observations. Peptilot has one-tap logging for doses, side effects, weight, and injection sites, so patterns show up in your own record.

Educational information for people who track their protocols — not medical advice, and never a recommendation to use any compound. Always work with a qualified healthcare provider.
