Side-by-side comparison
GHRH (Growth Hormone-Releasing Hormone) vs LL-37 Truncated Variants (KR-12 / KS-30)
Native 44-aa hypothalamic GHRH; parent molecule of sermorelin, CJC-1295, and tesamorelin. versus Shorter active fragments of LL-37 (KR-12, KS-30) with retained antimicrobial activity but lower toxicity.
GHRH (Growth Hormone-Releasing Hormone)
PerformanceNative 44-aa hypothalamic GHRH; parent molecule of sermorelin, CJC-1295, and tesamorelin.
Top benefits
- ✓Pulsatile GH release
- ✓Preserves natural HPA axis
- ✓Reference comparator for analogs
