This page helps you understand what to track for GHRP-6. It is not medical advice, a prescription, or a recommendation to use this peptide. Discuss dose, route, timing, storage, and safety with a qualified healthcare professional.

Overview

GHRP-6 is a synthetic hexapeptide ghrelin-receptor agonist. Its hallmark is a strong appetite spike — useful for users trying to gain weight or for cachexia research, problematic for those cutting. Like GHRP-2, it raises cortisol and prolactin alongside the GH pulse.

Also known as: Growth Hormone Releasing Peptide 6.

Mechanism and timing snapshot

Ghrelin/GHS-R1a receptor agonist; the strongest hunger response of the GHRP family due to higher ghrelin-mimetic activity in the hypothalamus.

Tracking defaults

These values come from Peppi's catalog so records can be prefilled consistently. They should be reviewed against your clinician's instructions before logging real-world use.

Catalog default dose100 mcg
Catalog dose range100 mcg - 300 mcg
Default routeSubQ
Frequency label1–3× daily
Best time label30 min before a major meal if hunger boost is desired.
Food noteAvoid carbs/fats within 30–60 min before dosing for strongest GH pulse — but appetite use case may override this.

Catalog protocol note

100 mcg subQ 1–3× daily, often pre-meal to leverage appetite stimulation.

Safety notes

Common and rare side effects listed in the catalog

  • Strong hunger spike (~30–60 min)
  • Mild flushing
  • Water retention
  • Vivid dreams
  • Tingling extremities
  • Cortisol elevation symptoms

Contraindications and warnings

  • Active malignancy
  • Cushing's syndrome
  • Eating disorders
  • Not FDA-approved for human use — sold as research-only.

Other considerations

  • Hunger response is the strongest of any GHRP — not suited to cuts.
  • If you want a clean GH pulse without hunger, use Ipamorelin.

Stacking and cycle notes

Stacks well withcjc-1295
Avoid combining noteOther ghrelin agonists simultaneously
Typical cycle label8–12
Typical break label4
Cycle guidanceTachyphylaxis develops; cycling required.

Tracking tips

  • Time doses 30 min before main meals if you want the hunger boost.
  • Avoid pre-cut — hunger is intense and persistent.
  • Pairs with CJC-1295 no-DAC for amplified GH pulse.
