The details

Administration
Subcutaneous injection
Format
Semax + Selank combo, 5mL vial
Typical dosing
250-500mcg subcutaneously, daily
Best for
Anxiety relief, cognitive performance, focus
Pairs well with
Thymosin Alpha-1, Epitalon
Mechanism
Semax increases BDNF levels and enhances dopamine and serotonin activity for cognitive performance. Selank modulates GABA and serotonin systems to produce anxiolytic effects. The combination provides both cognitive drive and emotional balance without sedation.

How it works

Signal

Semax/Selank is given as a subcutaneous injection on a provider-determined schedule — usually in the morning or daytime, since the goal is calm focus, not sleep.

Cellular response

Semax increases BDNF levels and enhances dopamine and serotonin activity for cognitive performance. Selank modulates GABA and serotonin systems to produce anxiolytic effects. Together they provide cognitive drive and emotional balance without sedation.

Outcome

Over the following days most people notice the background hum of anxiety turning down first (days 1–3), then easier sustained focus and a steadier response to stress (weeks 1–2), then consistent clarity, sharper recall, and faster learning (weeks 2–4) — with calm focus settling in as the baseline by weeks 4–8.
