Humanin vs Hexarelin
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Humanin
Humanin is a mitochondrial-derived peptide with potent cytoprotective effects. Discovered in 2001, it has shown promise in protecting against age-related diseases including Alzheimer's, cardiovascular disease, and diabetes.
Full details →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.

| Aspect | Humanin | Hexarelin |
|---|---|---|
| Mechanism | Binds to IGFBP-3 and BAX, inhibiting apoptosis. Activates STAT3 signaling and enhances cellular survival under stress. Protects mitochondrial function and reduces oxidative stress. | 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. |
| Typical Dosage | Research protocols vary widely. Studies have used doses from micrograms to milligrams depending on the analog and route. HNG (S14G-Humanin) is a more potent analog. | Typical dosing: 100-200mcg administered 2-3 times daily for 4-6 weeks, followed by an equal off period to allow receptor resensitization. |
| Administration | Subcutaneous or intraperitoneal injection in research. Various analogs exist with different potencies and stabilities. | Subcutaneous injection. Cycling is essential to maintain effectiveness. Often used in short bursts rather than continuous protocols. |
| Side Effects | Limited human data. Generally well-tolerated in animal studies. May affect glucose metabolism. | Water retention, cortisol and prolactin increase, hunger (moderate), tingling, and potential blood pressure effects. |
