Hexarelin vs KPV

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

Hexarelin

Hexarelin is a potent synthetic hexapeptide growth hormone secretagogue. It provides the strongest GH release among GHRPs but is associated with rapid desensitization of receptors.

KPV

KPV is a tripeptide (Lys-Pro-Val) derived from alpha-melanocyte-stimulating hormone (α-MSH). It retains the potent anti-inflammatory properties of the parent hormone without the tanning or other melanocortin effects.

Side-by-Side Comparison

Aspect	Hexarelin	KPV
Dose Range	100 mcg–300 mcg	200 mcg–500 mcg
Frequency	2x daily	1x daily
Cycle Length	8–12 weeks	4–8 weeks
Route	subcutaneous	subcutaneous
Mechanism	Acts as a ghrelin mimetic with high potency at the GHS receptor. Provides powerful GH release but receptor desensitization occurs faster than with other GHRPs, requiring cycling.	Inhibits NF-κB activation and reduces inflammatory cytokine production. Enters cells and directly modulates inflammatory signaling without requiring melanocortin receptors.
Typical Dosage	Typical dosing: 100-200mcg administered 2-3 times daily for 4-6 weeks, followed by an equal off period to allow receptor resensitization.	Oral/sublingual: 200-500mcg 1-3 times daily. Topical formulations for localized inflammation. Also used in enemas for gut inflammation.
Administration	Subcutaneous injection. Cycling is essential to maintain effectiveness. Often used in short bursts rather than continuous protocols.	Can be taken orally, sublingually, or as suppositories/enemas for gut inflammation. Topical use for skin conditions. Stable orally unlike most peptides.
Side Effects	Water retention, cortisol and prolactin increase, hunger (moderate), tingling, and potential blood pressure effects.	Generally very well-tolerated. Minimal systemic effects due to targeted anti-inflammatory action.
