CJC-1295 vs MK-677 (Ibutamoren)
An educational, source-based comparison of CJC-1295 and MK-677 (Ibutamoren) — how each peptide works, what it's researched for, and what to know before going deeper.
A synthetic analog of growth hormone-releasing hormone (GHRH). The non-DAC version has a short half-life that preserves pulsatile GH release, while DAC variants extend the half-life via albumin binding. Research focuses on stimulating endogenous GH and IGF-1 production via the pituitary.
- Endogenous GH pulse amplitude
- IGF-1 elevation
- Body composition in adult GH-deficient research
- Sleep architecture (slow-wave sleep)
- • GH-axis manipulation may affect glucose tolerance.
- • Banned in competitive sport (WADA).
- • Requires physician oversight in any therapeutic context.
Orally bioavailable non-peptide ghrelin mimetic.
Technically a small-molecule ghrelin receptor agonist (not a peptide), often grouped with peptide GH research. Orally bioavailable, it elevates GH and IGF-1 over 24 hours and increases appetite.
- GH/IGF-1 elevation in adults
- Lean mass and bone density in elderly
- Sleep quality (slow-wave sleep)
- • Not FDA-approved.
- • Insulin resistance and fluid retention reported.
- • Banned by WADA.
CJC-1295 vs MK-677 (Ibutamoren) — Key differences
- Class: CJC-1295 is classified as Growth Hormone Axis, while MK-677 (Ibutamoren) is Growth Hormone Axis · Small Molecule.
- Primary research focus: CJC-1295 — endogenous gh pulse amplitude; MK-677 (Ibutamoren) — gh/igf-1 elevation in adults.
