The Flow State Stack

A precision cognitive performance stack combining Russia's two most studied nootropic peptides with a cholinergic foundation. Semax provides dopaminergic drive and BDNF-mediated neuroplasticity; Selank provides GABAergic calm and anxiety reduction; Alpha-GPC provides the acetylcholine substrate both peptides work on. The result is a sustained, clear-headed flow state without stimulant side effects - designed for knowledge workers, creatives, and high performers.

Daily Schedule

Timing and dosage for each step

08:30 AM

300 mg

Take first on empty stomach. Provides acetylcholine substrate - the neurotransmitter foundation the peptides will act on. Allow 20 min before peptides.

08:50 AM

SemaxTier B

600 mcg

Intranasal spray - 1-2 drops per nostril (0.1% solution = 1 drop per 100mcg). Tilt head back slightly. Effects begin within 20-30 minutes.

08:50 AM

SelankTier A

500 mcg

Intranasal spray - administer in the opposite nostril from Semax, or alternate nostrils. Selank counterbalances Semax's stimulating edge, creating calm focus rather than anxious activation.

The Problem This Protocol Solves

Conventional cognitive enhancers force a trade-off: stimulants (caffeine, Adderall) increase arousal but also anxiety, jitter, and eventual crash. Anxiolytics reduce anxiety but also reduce drive and cognitive sharpness. Flow State Stack eliminates this trade-off by targeting the two systems separately and simultaneously.

Semax activates the dopaminergic focus system:

  • Upregulates BDNF (brain plasticity and learning)
  • Enhances prefrontal dopamine receptor sensitivity (focus, working memory)
  • Increases cognitive speed and executive function

Selank activates the calm/balance system:

  • Enhances GABA-A activity (anxiety reduction without sedation)
  • Modulates enkephalin (mood stabilisation)
  • Prevents the anxiety and cortisol spike that derails focus under pressure

Alpha-GPC provides the cholinergic fuel:

  • Supplies choline for acetylcholine synthesis
  • Acetylcholine is required for attention, working memory, and the synaptic strengthening that both peptides promote

What to Expect

Minutes 0-20: Alpha-GPC begins raising acetylcholine baseline
Minutes 20-40: Semax and Selank reach peak concentration; mental clarity arrives cleanly, without stimulant onset
Hours 1-4: Sustained focus window -- productive deep work, reduced distraction sensitivity, stable mood
Hours 4-6: Gentle taper; no crash

Optimal Use Cases

  • Deep work sessions (writing, coding, research, analysis)
  • High-stakes presentations or negotiations requiring calm confidence
  • Creative work requiring both divergent thinking and sustained attention
  • Learning-intensive days (the BDNF upregulation from Semax specifically enhances neuroplasticity)

Cycling

To prevent tolerance:

  • Semax: 2-4 weeks on, 1-2 weeks off
  • Selank: More forgiving -- some users take continuously
  • Run the full stack 3-4 days per week on demanding work days; off days allow receptor sensitivity to reset

Caffeine + L-Theanine as a Foundation

Many practitioners take 100mg caffeine + 200mg L-Theanine 30-60 minutes before this stack. Caffeine provides adenosine receptor blockade; L-Theanine smooths caffeine's edge via alpha-wave promotion. This creates a clean stimulant base before the peptide layer is added.
