Cortisol
The body's primary stress hormone, secreted by the adrenals under HPA-axis control — one thing Ipamorelin specifically does not raise.
Definition
Cortisol is a glucocorticoid produced by the adrenal cortex that mobilises glucose, suppresses inflammation and modulates immune response. It's tightly regulated by the HPA axis. Older GH secretagogues (GHRP-2, GHRP-6) triggered parallel cortisol and prolactin spikes along with GH; Ipamorelin's selectivity — no cortisol or prolactin rise — is one of its defining clinical advantages.

HPA AxisHypothalamic-Pituitary-Adrenal Axis
The feedback loop between hypothalamus, pituitary and adrenals that governs cortisol and stress response.
PeptideIpamorelin
A selective growth-hormone secretagogue that triggers GH release without spiking cortisol or prolactin — usually paired with CJC-1295.
MechanismGrowth HormoneGH
A pituitary-secreted hormone that drives protein synthesis, fat metabolism and tissue repair — released in pulses, peaking at night.
