- While CJC-1295 and ipamorelin are both capable of stimulating the synthesis of GH, the two peptides have significantly different mechanisms of action.
- CJC-1295 appears to increase mean GH levels for extended periods of time, while ipamorelin may induce short-term supraphysiological spikes in GH synthesis.
- Here are two notable studies that outline the GH-increasing effects of both CJC-1295 and ipamorelin:
- CJC-1295 administered as a subcutaneous injection to healthy study volunteers resulted in an increase in overall GH levels while maintaining GH pulsatility, with peak levels staying within normal ranges. Notably, a dose of 60mcg/kg resulted in an approximate 150% rise in mean GH levels, while a single dose of 250mcg/kg resulted in a 300% increase in 24-hour mean GH. When administered biweekly (twice over 14 days) at 60mcg/kg, this regimen consistently raised mean GH levels, with the effect persisting by day 28 [15].
- Comparatively, ipamorelin may induce significant GH pulses, particularly at higher doses. Research in healthy volunteers revealed that a single dose of ipamorelin at 100mcg/kg body weight significantly raised GH, with peaks reaching around 80mIU/l (approximately 26.6ng/ml). Elevated GH levels were also observed with smaller doses (60mcg/kg). Additionally, the same study indicated significant increases in GH even at a dosage of 10mcg/kg [14].
