Ipamorelin vs Ipamorelin + CJC-1295: GH Secretagogue Comparison

Ipamorelin alone is the most selective GH secretagogue available, acting on the GHS-R1a receptor without affecting cortisol or prolactin. The Ipamorelin + CJC-1295 (no DAC) blend adds a GHRH analogue for dual-pathway stimulation. Researchers studying growth hormone axis physiology compare these to evaluate whether single-receptor selectivity or dual-receptor amplification better suits their experimental protocols.
