Ipamorelin vs GHRP-2
Cleaner selective GHRP vs stronger GHRP.
| Attribute | Ipamorelin Selective GH secretagogue | GHRP-2 Growth Hormone Releasing Peptide 2 |
|---|---|---|
| Category | Muscle Growth & Performance | Muscle Growth & Performance |
| Best known for | Clean growth hormone pulse research | Reliable GH-release research |
| In plain English | Researchers like ipamorelin because it gives a clean GH pulse without raising cortisol or prolactin — making it the most-discussed 'starter' GH peptide. | Stronger GH pulse than ipamorelin but weaker than hexarelin, with mild appetite stimulation and small cortisol/prolactin bumps. |
| How it works | Selectively activates the GHSR receptor, stimulating pulsatile growth hormone release from the pituitary. | Activates the GHSR receptor to stimulate GH release. |
| Researchers study | GH secretion, IGF-1 elevation, body composition, and sleep quality. | GH secretion, appetite, and IGF-1 elevation. |
| Internet discussion | The default beginner GH peptide on forums. Discussed for sleep, recovery, and lean gains. | Used by researchers who want appetite stimulation alongside GH research. |
Ipamorelin
Clean growth hormone pulse research
Researchers like ipamorelin because it gives a clean GH pulse without raising cortisol or prolactin — making it the most-discussed 'starter' GH peptide.
Selectively activates the GHSR receptor, stimulating pulsatile growth hormone release from the pituitary.
GH secretion, IGF-1 elevation, body composition, and sleep quality.
The default beginner GH peptide on forums. Discussed for sleep, recovery, and lean gains.
Ipamorelin is the cleanest of the GH secretagogues, producing GH pulses without significant cortisol or prolactin increase.
GHRP-2
Reliable GH-release research
Stronger GH pulse than ipamorelin but weaker than hexarelin, with mild appetite stimulation and small cortisol/prolactin bumps.
Activates the GHSR receptor to stimulate GH release.
GH secretion, appetite, and IGF-1 elevation.
Used by researchers who want appetite stimulation alongside GH research.
GHRP-2 sits between ipamorelin and hexarelin in potency and side-effect profile.
