Is there an approved GHRP-6 dose?

No. GHRP-6 was never FDA approved, so there is no label or official dose. Community protocols report roughly 100–300 mcg by subcutaneous injection, two to three times daily, provided here for education only and not as instructions for use.

What makes GHRP-6 different from the other GHRPs?

Its most distinctive feature is pronounced appetite stimulation — it acts strongly at the ghrelin receptor, so intense hunger shortly after dosing is a hallmark. It also raises cortisol and prolactin more than the selective option, ipamorelin.

When is GHRP-6 dosed?

Community timing typically follows the GH rhythm — pre-bed and/or around training — and it is often paired with a GHRH analog such as CJC-1295. These are conventions from community use, not a validated schedule.

⚠️ No approved or validated human dose

GHRP-6 is investigational and was never FDA approved. There is no label or official dose. The figures below reflect community practice, documented for education — not instructions for use. An unapproved injectable carries unknowns of identity, purity, and sterility.

The short version

GHRP-6 is one of the original growth-hormone-releasing peptides — a hexapeptide that activates the ghrelin receptor to trigger a GH pulse. Its defining real-world characteristic is strong appetite stimulation: because it works through the "hunger hormone" receptor, intense hunger soon after a dose is its signature. That effect is the main thing that sets it apart from its siblings and shapes how it is used.

What community protocols report

Parameter	Commonly reported
Amount	~100–300 mcg per dose
Frequency	2–3× daily
Timing	Pre-bed and/or around training
Route	Subcutaneous

The appetite spike is sometimes treated as a feature (for people trying to eat more) and sometimes as a nuisance — either way it is the most predictable effect. As with the rest of the family, GHRP-6 is frequently paired with a GHRH analog like CJC-1295, and the timing follows the body's GH rhythm rather than any validated schedule.

🔎 Where GHRP-6 sits in the family

GHRP-6 = strongest appetite effect. GHRP-2 = more GH release, moderate appetite/cortisol. Ipamorelin = cleanest/most selective, least off-target effect. People generally pick based on whether they want potency, selectivity, or the appetite effect. See the GHRP-2 and ipamorelin dosage pages.

Reconstitution basics

GHRP-6 is supplied as a lyophilized powder requiring reconstitution with bacteriostatic water before microgram doses can be measured. The Reconstitution Calculator converts vial strength and diluent volume into an exact draw; it cannot verify what is in an unregulated vial.

Frequently asked questions

Why does GHRP-6 make me so hungry?

It strongly activates the ghrelin receptor, and ghrelin is the body's hunger signal — so a sharp rise in appetite shortly after dosing is expected and is its most reliable effect.

Is GHRP-6 stronger than ipamorelin?

It is less selective and comes with more off-target effects (appetite, cortisol, prolactin); ipamorelin is preferred when people want GH release without those.

Is it legal?

It is not an approved medicine; it circulates as a research compound and status varies by jurisdiction — see the Regulatory Status Tracker.
