01Mechanism of Action
Parameter
KPV
Semax
Primary target
Intracellular targets bypassing melanocortin receptors (proposed)Dalle-Pang 2024
BDNF / NGF expression + monoamine modulationKaplan 2017
Pathway
NF-κB inhibition + cytokine modulation (TNF-α, IL-1β, IL-6) → reduced inflammationDalle-Pang 2024
↑ BDNF + NGF synthesis + 5-HT modulation → neuroplasticity + anxiolysis + cognitive enhancementKaplan 2017
Downstream effect
Anti-inflammatory action without α-MSH pigmentation effects; gut barrier protectionDalle-Pang 2024
Improved memory + attention; reduced anxiety; neuroprotection in ischemiaKaplan 2017

Origin

05Administration Protocol
Parameter
KPV
Semax
1. Reconstitution
Add 1 mL bacteriostatic water to vial per labelling.
Pre-formulated nasal spray (commercial) or research vial reconstituted with bacteriostatic water.
2. Form
SQ injection (acute), oral capsule (chronic / gut), topical for skin indications.
Intranasal — 2–3 sprays per nostril per dose. Tilt head slightly back.
3. Timing
Morning preferred; oral form taken with / before meals.
Morning + early afternoon. Avoid evening (sleep disruption).
4. Storage
Lyophilised: room temp, light-protected. Reconstituted: refrigerate ≤30 days.
Refrigerate after reconstitution; light-protected.
5. Needle
29–31G insulin syringe (SQ form).
Cycle on/off to avoid neurochemical adaptation.
06Stack Synergy
KPV
+ BPC-157
StrongKPV (NF-κB inhibition, cytokine reduction) + BPC-157 (VEGF-driven angiogenesis, tissue regeneration) form the classic gut-healing stack. KPV reduces inflammatory drive; BPC-157 promotes mucosal repair. Anecdotally favoured for IBD, ulcerative colitis, and post-surgical gut recovery.
- KPV
- 200–500 mcg oral · daily
- BPC-157
- 250–500 mcg oral or SQ · daily
- Primary benefit
- Combined anti-inflammation + mucosal repair for gut conditions
Semax
+ Selank
ModerateSemax (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
