# GHRP-6

> GHRP-6 is one of the earliest synthetic growth hormone releasing hexapeptides, studied since the late 1980s for its ability to stimulate GH secretion through ghrelin-receptor mimicry. It is notable within the GHRP class for a pronounced appetite-stimulating effect, which has made it a longstanding research tool for studying hunger regulation as well as GH release. Reported use spans recovery support, sleep quality, and appetite support in bulking-oriented protocols. Its side-effect profile, particularly hunger and water retention, is more pronounced than newer, more selective GHRPs.

- Also known as: GH-Releasing Hexapeptide
- Primary category: Growth Hormone Peptides
- Effectiveness rank: #8 in Muscle & Performance; #3 in Growth Hormone Peptides
- Evidence level: Well studied
- Route: Subcutaneous (Injected subcutaneously; often dosed on an empty stomach due to pronounced appetite effect)
- Dose range: 100-300 mcg
- Dose tiers: low 100 mcg; moderate 200 mcg; high 300 mcg
- Half-life: ~20-30 min
- Timing: ~30 min before bed, empty stomach
- Cycle: 8-12 weeks on, 4 weeks off (Community reports suggest appetite effects and GH response may blunt with continuous long-term use)
- Storage: Store lyophilized powder refrigerated (2-8°C), protected from light. After reconstitution with bacteriostatic water, keep refrigerated and use within 2-4 weeks.

## Mechanism of action

GHRP-6 activates the growth hormone secretagogue receptor (GHS-R1a), mimicking ghrelin to trigger pulsatile GH release from the anterior pituitary. The same receptor activation strongly engages hypothalamic appetite centers, producing marked hunger shortly after dosing. Repeated stimulation is also reported to modestly raise cortisol and prolactin.

## Reported benefits

- Strong appetite stimulation
- Increased GH/IGF-1 output
- Improved recovery
- Potential lean mass support during caloric surplus

## Reported side effects

- Pronounced hunger
- Water retention
- Cortisol/prolactin elevation
- Injection-site reactions
- Reported lethargy at higher doses

## Common protocols

- GHRP-6 + CJC-1295 (no DAC)
- Bulking appetite-support protocol

## Stacking notes

Often combined with a GHRH analog for synergistic GH release; its appetite effect makes it better suited to bulking-phase stacks than fat-loss-oriented ones.
