What it's actually good for

Recovery

Research Supported

Reliably increases growth hormone levels which facilitates tissue repair and systemic recovery.

Muscle

Mixed Evidence

Increases GH but muscle mass gains are often secondary to increased caloric intake from hunger.

Sleep

Weak Evidence

Users report deeper sleep due to GH pulses, but clinical data on sleep architecture is limited.

How it works

GHRP-2 is a synthetic hexapeptide that acts as a potent growth hormone secretagogue by mimicking ghrelin. While it effectively increases serum growth hormone levels in clinical diagnostic settings, its long-term safety and efficacy for performance enhancement in healthy humans remain unproven.

It acts as a selective agonist of the growth hormone secretagogue receptor (GHS-R), stimulating the pituitary gland to release growth hormone pulses while also increasing appetite through ghrelin pathways.

Safety

  • Can significantly increase cortisol and prolactin levels at higher doses.
  • Causes intense, often uncontrollable hunger shortly after administration.
  • May lead to water retention and decreased insulin sensitivity with chronic use.
