CJC-1295 + Ipamorelin
Quick Reference
Overview
This collection is the classic GHRH + GHRP peptide pairing — the one that has served as the reference combination for growth-hormone research for more than two decades. CJC-1295 supplies the growth-hormone releasing hormone signal (GHRH). Ipamorelin activates a separate receptor (the ghrelin receptor) to trigger a different kind of release.
This combination has become the baseline against which most newer GH peptides are measured. Its predictable pattern of growth-hormone pulses is what makes it useful as a reference point in published research.
The Components
Growth Hormone Secretagogues
CJC-1295 No DAC
A synthetic version of the body’s own growth hormone signal (GHRH). Researchers study CJC-1295 to understand how extending this signal affects the natural pulses of growth hormone that the pituitary gland releases throughout the day.

Growth Hormone Secretagogues
Ipamorelin
A peptide that triggers growth hormone release through the ghrelin receptor — a separate pathway from CJC-1295. Unlike older peptides in its class, Ipamorelin is studied for how cleanly it works without also raising cortisol or prolactin, two hormones that often come along for the ride.

Why This Combination
These two peptides work on separate pathways, which is why researchers often pair them. Think of CJC-1295 as extending the duration of the body’s growth hormone signal, while Ipamorelin is research-suggested to influence the size of each individual pulse. Used together, research suggests they act on growth hormone release differently than either compound does on its own.
Published studies examine how this combined approach affects IGF-1 responses (IGF-1 is a hormone that reflects overall growth hormone activity) relative to either peptide alone. Ipamorelin is often chosen for this pairing for its selectivity — research describes it as more selective than some older peptides in the same class.
Research Notes
The GHRH + GHRP pairing has been studied extensively since the early 2000s, with detailed work by Sigalos, Walker, and others characterising how the combination behaves over time. Ipamorelin itself was first described by researchers at Novo Nordisk in 1998. Neither peptide is approved for therapeutic use in Australia.
How Researchers Use This Collection
Research protocols typically track IGF-1 levels in blood as the main readout, with detailed GH pulse profiling (serial blood draws over several hours) where budget and logistics allow. Comparison arms usually include GHRH-alone and GHRP-alone groups so researchers can measure how much of the effect comes from combining the two.
Storage & Handling
Store at 2–8°C in a cool, dry place. Protect from light and moisture. Refrigerate once in solution form.
