How this works
Semax is an ACTH(4–10) analog studied for BDNF modulation, neurotransmission, and neuroprotection. Selank is a tuftsin analog studied for anxiolytic, anti-asthenic, and stress-response effects.

Research highlights
Semax is an ACTH(4–10) analog studied for BDNF modulation and neurotransmission.
Selank is a tuftsin analog studied for anxiolytic and stress-response pathways.
Both peptides appear in the literature primarily via intranasal research routes.
Storage
- Lyophilized: freeze around −20 °C in dry, dark conditions.
- Reconstituted: refrigerate at 2–8 °C and use within about 30 days.
- Protect from light and avoid freeze–thaw cycles.
