Hexarelin vs Argireline

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.

Argireline

Argireline (Acetyl Hexapeptide-3) is a widely-used cosmetic peptide that reduces wrinkle depth by inhibiting neurotransmitter release. One of the first 'Botox-like' peptides developed for topical use.

Side-by-Side Comparison

AspectHexarelinArgireline
MechanismActs 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 the formation of the SNARE complex required for neurotransmitter release, reducing the intensity of muscle contractions that cause expression lines.
Typical DosageTypical dosing: 100-200mcg administered 2-3 times daily for 4-6 weeks, followed by an equal off period to allow receptor resensitization.Topical: 5-10% concentration in serums, applied twice daily. Higher concentrations used in professional treatments.
AdministrationSubcutaneous injection. Cycling is essential to maintain effectiveness. Often used in short bursts rather than continuous protocols.Topical application to clean skin. Most effective on expression lines (forehead, crow's feet). Consistent use required for visible results.
Side EffectsWater retention, cortisol and prolactin increase, hunger (moderate), tingling, and potential blood pressure effects.Generally very well-tolerated. Occasional mild irritation or dryness. No systemic absorption at cosmetic doses.
