Growth Hormone Releasing Peptides: Mechanisms & Research
Growth hormone axis peptides are often grouped together, but they are not mechanistically identical.
GH Axis Primer
- GHRH signaling stimulates GH release.
- Ghrelin receptor signaling also modulates GH pulse dynamics.
- Somatostatin acts as an inhibitory regulator.
Major Classes
GHRPs
Examples include ipamorelin and GHRP variants acting through ghrelin-related pathways.
GHRHs
Examples include CJC-1295 variants and mod-GRF analogs acting on GHRH pathways.
What Researchers Compare
- Pulse profile characteristics
- Tolerability patterns
- Downstream markers (for example IGF-related trends)
- Protocol practicality over time
Practical Takeaway
Use mechanism-aware comparisons instead of treating GH-axis peptides as interchangeable.
