GHRP-2
Also known as Growth Hormone Releasing Peptide-2, KP 102
GHRP-2 is one of the most potent GH secretagogues available, producing strong GH pulses but with more side effects than Ipamorelin — notably increased cortisol, prolactin, and significant hunger. Favored by bodybuilders for aggressive GH stimulation.
How it works
Potent GHSR agonist that stimulates GH release while also increasing cortisol and prolactin. Stronger GH pulse amplitude than Ipamorelin.
Benefits
- Very strong GH release — more potent than Ipamorelin
- Significant IGF-1 increases
- Accelerated muscle growth and fat loss
- Strong recovery and anti-aging effects
- Some appetite stimulation (useful for hardgainers)
