GHRP-2 vs GHRP-6

GHRP-2 and GHRP-6 are growth-hormone-releasing peptides studied at the ghrelin receptor. They are close relatives, and the literature usually contrasts them on potency and on how strongly each engages appetite-related signaling.

Aspect	GHRP-2	GHRP-6
Receptor	GHS-R1a (ghrelin)	GHS-R1a (ghrelin)
Relative potency in literature	Higher per-weight secretagogue potency	Classic reference GHRP
Appetite-pathway signaling	Lower relative appetite signaling	More pronounced appetite-pathway signaling
Format / purity	Lyophilized · ≥99% HPLC	Lyophilized · ≥99% HPLC

Close relatives, studied for different emphasis

Both peptides act at the ghrelin receptor. GHRP-2 is often described as the more potent secretagogue per weight with comparatively lower appetite-pathway signaling, while GHRP-6 is the classic reference compound noted for more pronounced appetite-related activity in research models.

Questions

What is the difference between GHRP-2 and GHRP-6?

Both are ghrelin-receptor growth-hormone-releasing peptides. GHRP-2 is generally described as more potent per weight with lower appetite-pathway signaling; GHRP-6 is the classic reference GHRP with more pronounced appetite-related activity.

What purity are GHRP-2 and GHRP-6?

Both are supplied as lyophilized powder at ≥99% HPLC purity. All compounds are sold strictly For Research Use Only — not for human or animal consumption, and not intended to diagnose, treat, cure, or prevent any disease.
