Dihexa vs Humanin
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Dihexa
Dihexa is a nootropic peptide derived from angiotensin IV. It has shown remarkable cognitive-enhancing properties in animal studies, being described as potentially millions of times more potent than BDNF.
Full details →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.

| Aspect | Dihexa | Humanin |
|---|---|---|
| Mechanism | Acts as a hepatocyte growth factor (HGF) potentiator by binding to its receptor c-Met. Promotes synaptogenesis, neuronal survival, and cognitive enhancement through this pathway. | Binds to IGFBP-3 and BAX, inhibiting apoptosis. Activates STAT3 signaling and enhances cellular survival under stress. Protects mitochondrial function and reduces oxidative stress. |
| Typical Dosage | Research dosing is highly variable due to extreme potency. Typical range: 10-40mg orally or sublingually. Start with lowest doses due to potency. | 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. |
| Administration | Can be taken orally, sublingually, or intranasally. Extremely potent - careful dosing is essential. Best used cyclically. | Subcutaneous or intraperitoneal injection in research. Various analogs exist with different potencies and stabilities. |
| Side Effects | Limited human data. Reported effects include headache, temporary brain fog during adjustment, and potential mood changes. | Limited human data. Generally well-tolerated in animal studies. May affect glucose metabolism. |
