Key Facts: GHRP-6

Category: Growth Hormone
FDA Status: Not FDA Approved
Clinical Status: Preclinical/Investigational - FDA Category 2 (restricted from compounding; expected to remain restricted after 2026 reclassification due to cortisol/prolactin concerns)
Administration: Subcutaneous injection, ideally fasted
Typical Dose: 100-300 mcg 2-3x daily
Frequency: 2-3x daily
Duration: 8-12 weeks

Also Known As

Growth Hormone Releasing Peptide 6, SKF-110679

Mechanism of Action

GHRP-6 binds to ghrelin receptors (GHSR-1a) in the hypothalamus and pituitary, triggering a strong GH release. It also activates the hunger-signaling pathway, leading to significant appetite increase. Stimulates cortisol and prolactin more than newer GHRPs.

Research Summary

Well-studied peptide showing reliable GH release. Research demonstrates cardioprotective effects in animal models, improved wound healing, and significant appetite stimulation. Studies show 3-6 fold increase in GH levels.

Timing & Administration

Best Time to Take

Before bed or morning (fasted)

2-3 times daily, 30 min before meals or before bed

Food Recommendation

Take on empty stomach

Why This Timing?

GHRP-6 stimulates GH release and increases appetite. Take fasted for maximum GH response. Evening dose supports natural nighttime GH surge.

Possible Side Effects

Not everyone experiences these effects. Individual responses vary based on dosage, duration, and personal factors.

●Significant hunger increase (most pronounced of all GHRPs)
●Water retention
●Elevated cortisol levels
●Elevated prolactin levels
●Flushing
●Nausea
●Headache
●May trigger histamine release - use caution with MCAS or histamine sensitivity
●Limited long-term safety data
