Sermorelin & GHRP-2 & GHRP-6 vs HGH Fragment 176-191
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Sermorelin & GHRP-2 & GHRP-6
A powerful tri-blend combining Sermorelin (a GHRH analog) with two growth hormone releasing peptides. This combination produces significantly greater GH release than any single peptide, with studies showing up to 54-fold increases in pulsatile GH secretion.
Full details →HGH Fragment 176-191
HGH Fragment 176-191 is the fat-reducing portion of the growth hormone molecule. Unlike AOD-9604 (which has an additional tyrosine), this is the exact fragment of HGH responsible for lipolytic effects.

| Aspect | Sermorelin & GHRP-2 & GHRP-6 | HGH Fragment 176-191 |
|---|---|---|
| Mechanism | Sermorelin stimulates the pituitary via GHRH receptors, while GHRP-2 and GHRP-6 act as ghrelin mimetics on different receptor subtypes. The combination creates synergistic GH release through multiple complementary pathways. GHRP-6 also strongly stimulates appetite. | Mimics the lipolytic region of growth hormone, stimulating fat breakdown and inhibiting lipogenesis without affecting blood sugar or promoting growth. Works independently of GH receptors. |
| Typical Dosage | Typical protocols: Sermorelin 100-300mcg, GHRP-2 100-300mcg, GHRP-6 100-300mcg. Often administered 2-3 times daily, 30 minutes before meals or at bedtime. | Typical dosing: 250-500mcg daily, often split into 2-3 doses. Usually administered on empty stomach, often with fasted cardio. |
| Administration | Subcutaneous injection. Best administered fasted or before sleep to maximize natural GH cycle. The three peptides can be mixed together or administered separately. | Subcutaneous injection. Best results when used fasted and combined with exercise. Avoid eating for 30 minutes post-injection. |
| Side Effects | Increased hunger (especially from GHRP-6), water retention, facial flushing, nausea, tingling, potential increases in cortisol and prolactin levels. | Generally well-tolerated. May cause injection site irritation, temporary lethargy, or headache. Does not affect blood glucose significantly. |
