What's in it

Selank

Russian-origin synthetic peptide. Anxiolytic and cognitive support without the sedation profile of benzos.

See entry →

Semax

For alertness and focus. A Russian-origin nootropic peptide on the alert/focus end of the spectrum that pairs with Selank for a balanced cognitive stack.

Why they're paired

Calm + clear. Selank is on the anxiolytic end of the spectrum; Semax is on the alert/focus end. Both are Russian-origin nootropic peptides. Combining them theoretically gives you the calm baseline of Selank with the focus lift of Semax, useful in demanding work contexts.

Who runs it

Users with situational anxiety AND cognitive-load demands. People tapering off stimulants or benzos under medical guidance who want a gentler combination.

Blend vs running singles

Both peptides have meaningful effects on their own. Most users start with one, learn what it feels like, then add the other if they want to round out the profile. Pre-blended is convenient but obscures which peptide is doing what for you.
