05Administration Protocol

Parameter

Chonluten

Semax

1. Preparation

Typically supplied as capsules or sublingual tablets. No reconstitution required. Store in cool, dry place away from light.

Pre-formulated nasal spray (commercial) or research vial reconstituted with bacteriostatic water.

2. Oral route

Swallow capsule with water, 20–30 minutes before meals or as directed. Traditional Khavinson protocol emphasizes empty stomach for absorption.

Intranasal — 2–3 sprays per nostril per dose. Tilt head slightly back.

3. Sublingual route

Place tablet under tongue, allow dissolution for 1–2 minutes. Avoid swallowing immediately. Claimed to bypass first-pass metabolism.

Morning + early afternoon. Avoid evening (sleep disruption).

4. Timing

Morning dose preferred; may split into twice-daily if higher dose used. Consistency emphasized in bioregulator protocols.

Refrigerate after reconstitution; light-protected.

5. Cycle protocol

10–30 day cycles common in Russian tradition. Rest period of 1–3 months between cycles often recommended, though no published evidence for this approach.

Cycle on/off to avoid neurochemical adaptation.

06Stack Synergy

Chonluten

— no documented stacks

Semax

+ Selank

Moderate

View Selank →

Semax (cognitive enhancer, BDNF/NGF) and Selank (anxiolytic + immune) form the canonical Russian "neuro stack" — both intranasal peptide bioregulators with complementary axes. Semax for cognitive demand; Selank for stress mitigation.

Semax: 200–600 mcg intranasal · morning + afternoon
Selank: 150–300 mcg intranasal · midday + early evening
Primary benefit: Cognitive enhancement + stress mitigation
