How do Semax and Selank differ in mechanism?

Semax: ACTH(4-10)-derived heptapeptide that upregulates BDNF and NGF, modulates dopaminergic and serotonergic signalling, and reduces neuroinflammation markers. Selank: Tuftsin analogue extended with Pro-Gly-Pro that modulates GABA-A receptor expression, inhibits enkephalinase, and upregulates serotonin synthesis without sedation.

What research concentrations are referenced for Semax and Selank?

Semax is catalogued at 10mg. Selank is catalogued at 10mg. Concentrations and reconstitution volumes are documented on each product page for laboratory reference.

Are Semax and Selank sold for human use?

No. Semax and Selank are sold strictly for in vitro laboratory research use. They are not for human consumption, medical use, or self-administration, and they have not been evaluated by the FDA.

Where can I read the published research on Semax and Selank?
