GHRP-6
Growth Hormone Releasing Peptide-6. Synthetic hexapeptide GH secretagogue. Strong GH release with pronounced appetite stimulation. Popular for bulking phases.
Overview
Growth Hormone Releasing Peptide-6. Synthetic hexapeptide GH secretagogue. Strong GH release with pronounced appetite stimulation. Popular for bulking phases.
Elevates GH and IGF-1 levels, significant appetite stimulation (ghrelin mimetic), transient cortisol and ACTH elevation post-injection, may mildly elevate prolactin, can elevate fasting glucose with prolonged use
Compound Guide
Structure: Synthetic hexapeptide GH secretagogue. First-generation GHRP. Binds ghrelin receptor (GHS-R1a) with strong appetite-stimulating activity.
Dosage:
- Standard: 100-200mcg 2-3x/day SubQ
- Combined with mod-GRF: 100mcg GHRP-6 + 100mcg mod-GRF per injection, 2-3x/day
- Appetite stimulation (bulking): 200-300mcg pre-meal
Administration:
- SubQ injection, 27-30g insulin syringe
- Best on empty stomach — intense hunger within 20-30 min post-injection
- Space injections 3-4 hours apart
Key Notes:
- Most pronounced appetite stimulation of any GH peptide — hunger can be overwhelming
- Useful during bulking phases when difficulty eating is a limiting factor
- Transient cortisol/ACTH spike post-injection — generally clinically insignificant but higher than Ipamorelin or GHRP-2
- Good GH release but "dirtier" side effect profile than Ipamorelin (more cortisol, prolactin, hunger)
- Synergistic with GHRH analogs — combine for maximum GH pulse
- Reconstitute with bacteriostatic water, store refrigerated
- Monitor: IGF-1, fasting glucose, prolactin, cortisol
