Hexarelin vs Ipamorelin
| Attribute | Hexarelin Hexapeptide GH secretagogue | Ipamorelin Selective GH secretagogue |
|---|---|---|
| Category | Muscle Growth & Performance | Muscle Growth & Performance |
| Best known for | Potent GH release and cardioprotection research | Clean growth hormone pulse research |
| In plain English | The strongest GH-pulse peptide of the classic GHRPs — but also the one most likely to raise prolactin and cortisol, and develop tolerance. | Researchers like ipamorelin because it gives a clean GH pulse without raising cortisol or prolactin — making it the most-discussed 'starter' GH peptide. |
| How it works | Strongly activates GHSR and also exerts CD36-mediated cardioprotective effects. | Selectively activates the GHSR receptor, stimulating pulsatile growth hormone release from the pituitary. |
| Researchers study | GH secretion, cardiac tissue protection, and post-MI recovery. | GH secretion, IGF-1 elevation, body composition, and sleep quality. |
| Internet discussion | Discussed for short, intense research protocols due to tolerance. | The default beginner GH peptide on forums. Discussed for sleep, recovery, and lean gains. |
Hexarelin
Potent GH release and cardioprotection research
The strongest GH-pulse peptide of the classic GHRPs — but also the one most likely to raise prolactin and cortisol, and develop tolerance.
Strongly activates GHSR and also exerts CD36-mediated cardioprotective effects.
GH secretion, cardiac tissue protection, and post-MI recovery.
Discussed for short, intense research protocols due to tolerance.
Hexarelin is the most potent classic GHRP with notable cardioprotective research signals.
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.
