Hexarelin vs Human Growth Hormone (HGH)

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.

Human Growth Hormone (HGH)

Human Growth Hormone (somatropin) is a 191-amino acid protein identical to naturally produced GH. FDA-approved for growth hormone deficiency, Turner syndrome, and other conditions. Widely used off-label for anti-aging and performance.

Side-by-Side Comparison

AspectHexarelinHuman Growth Hormone (HGH)
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.Binds to GH receptors throughout the body, stimulating IGF-1 production in the liver. Promotes protein synthesis, fat metabolism, and cellular regeneration across multiple tissues.
Typical DosageTypical dosing: 100-200mcg administered 2-3 times daily for 4-6 weeks, followed by an equal off period to allow receptor resensitization.Medical: 0.1-0.3mg/kg/week divided into daily doses. Anti-aging: 1-2 IU daily. Performance: 2-6 IU daily, sometimes higher.
AdministrationSubcutaneous injection. Cycling is essential to maintain effectiveness. Often used in short bursts rather than continuous protocols.Subcutaneous injection, preferably at night to mimic natural pulsatile release. Rotate injection sites. Store refrigerated.
Side EffectsWater retention, cortisol and prolactin increase, hunger (moderate), tingling, and potential blood pressure effects.Joint pain, water retention, carpal tunnel syndrome, potential insulin resistance, and acromegaly features with long-term high doses.
