CJC-1295 vs IGF-1 LR3
An educational, source-based comparison of CJC-1295 and IGF-1 LR3 — 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.
A modified form of insulin-like growth factor-1 with an Arg3 substitution and N-terminal extension that reduces binding to IGFBPs, dramatically extending its half-life and free fraction in circulation.
- Muscle protein synthesis (preclinical)
- Tissue repair signaling
- Cell-culture growth applications
- • Hypoglycemia risk via insulin-receptor cross-activity.
- • Not FDA-approved for human therapeutic use; banned by WADA.
CJC-1295 vs IGF-1 LR3 — Key differences
- Class: CJC-1295 is classified as Growth Hormone Axis, while IGF-1 LR3 is Growth Factor.
- Primary research focus: CJC-1295 — endogenous gh pulse amplitude; IGF-1 LR3 — muscle protein synthesis (preclinical).
