CJC-1295 + Ipamorelin: GH Optimization

A foundational growth hormone secretagogue stack pairing a GHRH analogue (CJC-1295) with a selective GH secretagogue (Ipamorelin). CJC-1295 amplifies GH output by extending GHRH signal duration, while Ipamorelin triggers additional GH pulses through the ghrelin receptor with minimal cortisol or prolactin elevation. Together they produce synergistic, more physiologically natural GH release compared to either peptide alone.

Mechanism

Compound 1Fat Loss

CJC-1295

Acts as the long-acting GHRH analogue backbone of the stack, extending natural GH pulse duration and amplitude through its DAC modification. Its sustained activity makes it the primary driver of elevated GH output across the dosing window.

+
Compound 2Performance

Ipamorelin

A highly selective ghrelin receptor agonist that triggers additional GH pulses with negligible cortisol or prolactin co-stimulation, making it the cleanest available complement to a GHRH analogue. It synergises with CJC-1295 by activating GH release through an entirely distinct receptor pathway.

Synergistic Effect

Dual-pathway activation

CJC-1295 × Ipamorelin

Safety Notes

Both peptides are unapproved research compounds that stimulate endogenous growth hormone release. Contraindicated in individuals with active or suspected hormone-sensitive malignancies. Potential side effects include water retention, joint discomfort, and changes in insulin sensitivity consistent with elevated GH. Not for use during pregnancy or breastfeeding.
