CJC-1295
Synthetic analogue of growth-hormone-releasing hormone (GHRH), modified for extended half-life via a Drug Affinity Complex (DAC) binding to albumin. Acts on the pituitary GHRH receptor and stimulates endogenous growth-hormone release.
Sermorelin
Synthetic analogue of the first 29 amino acids of human growth-hormone-releasing hormone (GHRH). Stimulates pulsatile endogenous growth-hormone secretion from the pituitary via the GHRH receptor. Very short plasma half-life — pharmacodynamic effect lasts several hours nevertheless.

Frequently asked questions
- What is the difference between CJC-1295 and Sermorelin?
- CJC-1295 is classified as "Growth", while Sermorelin is classified as "Growth". CJC-1295: Long-acting synthetic GHRH analogue modified for albumin binding (DAC). Stimulates endogenous growth-hormone release. Pharmacodynamic effect established in small human studies; clinical endpoint trials are missing. Sermorelin: Synthetic analogue of the first 29 amino acids of human GHRH. Stimulates pulsatile growth-hormone secretion from the pituitary. Formerly FDA-approved as Geref Diagnostic, now withdrawn in many markets — compounding and research use dominate. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, CJC-1295 or Sermorelin?
- The highest available evidence level is "Human trial" for CJC-1295 and "Human RCT" for Sermorelin. A higher evidence level means more robust data, but says nothing about suitability for an individual. The full body of evidence is on each peptide's own page.
- What is the legal status of CJC-1295 and Sermorelin in Germany and the United States?
- Germany: CJC-1295 — Unapproved, Sermorelin — Unapproved. United States: CJC-1295 — Research only, Sermorelin — Research only. These are factual summaries with source and review date on the individual pages.
