Adamax vs Dihexa
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Adamax
Adamax is a modified version of Semax with an adamantane group attached, designed to enhance its nootropic effects and extend duration of action compared to standard Semax.
Full details →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 →Side-by-Side Comparison
| Aspect | Adamax | Dihexa |
|---|---|---|
| Dose Range | 200 mcg–750 mcg | 5 mg–20 mg |
| Frequency | 1x daily | 1x daily |
| Cycle Length | 2–4 weeks | 4–12 weeks |
| Route | intranasal | oral |
| Mechanism | Similar to Semax - enhances BDNF expression and modulates dopamine/serotonin systems. The adamantane modification may increase lipophilicity and CNS penetration. | 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. |
| Typical Dosage | Intranasal: 100-500mcg 1-2 times daily. Lower doses than standard Semax may be effective due to enhanced potency. | Research dosing is highly variable due to extreme potency. Typical range: 10-40mg orally or sublingually. Start with lowest doses due to potency. |
| Administration | Intranasal spray is most common route. More stable than standard Semax. Often used for acute cognitive enhancement. | Can be taken orally, sublingually, or intranasally. Extremely potent - careful dosing is essential. Best used cyclically. |
| Side Effects | Similar to Semax - possible irritability, hair shedding, or overstimulation. May have stronger effects than standard Semax. | Limited human data. Reported effects include headache, temporary brain fog during adjustment, and potential mood changes. |
