Growth hormone (GH) secretion drops steadily after age 30, contributing to increased visceral adiposity, reduced muscle mass, thinner skin, and prolonged recovery times. CJC-1295 and Ipamorelin are growth hormone secretagogues that restore youthful GH dynamics without replacing the hormone directly.
### Dual Mechanism: GHRH + Ghrelin Receptor Agonism
* **CJC-1295:** A synthetic analog of Growth Hormone-Releasing Hormone (GHRH). It binds to GHRH receptors on pituitary somatotropes, extending the duration and magnitude of endogenous GH pulses.
* **Ipamorelin:** A selective Ghrelin/Growth Hormone Secretagogue Receptor (GHSR) agonist. It stimulates GH release through an independent biological pathway.
When combined, these two peptides act synergistically, producing a natural, pulsatile surge of growth hormone far greater than either peptide achieves alone.
### Why Pulsatile Release Matters
Exogenous Human Growth Hormone (hGH) injections suppress natural pituitary production and can cause insulin resistance, fluid retention, or elevated prolactin/cortisol. CJC-1295 and Ipamorelin maintain normal negative feedback loops:
* **No Cortisol or Prolactin Spikes:** Ipamorelin is highly selective and does not stimulate stress hormone release.
* **Enhanced Insulin-like Growth Factor 1 (IGF-1):** Promotes cellular repair, collagen synthesis, lipolysis (fat loss), and lean body mass retention.
### Health and Rejuvenation Benefits
Regular therapy supports deep stage-IV sleep, faster muscle recovery, elevated basal metabolic rate, and improved skin thickness and connective tissue elasticity.
