HGH Fragment 176-191 Side Effects
- ⚠Injection site irritation, headache, drowsiness. Does not affect blood sugar, insulin sensitivity, or elevate IGF-1.
GHRP-6 Side Effects
- ⚠Common: Increased appetite (significant), water retention, tingling
- ⚠Moderate: Cortisol elevation (dose-dependent), lethargy
- ⚠Rare: Elevated prolactin at high doses
Research Overview
HGH Fragment 176-191
This 16-amino-acid fragment specifically targets adipose tissue via beta-3 adrenergic receptors. Works through a GH-receptor-independent pathway, explaining selective fat-loss properties without growth-promoting effects.
GHRP-6
GHRP-6 has solid pre-clinical and clinical evidence for GH stimulation. Well-characterized pharmacology. More appetite stimulation than Ipamorelin due to ghrelin receptor activation.
