01Mechanism of Action

Parameter
DSIP
KPV
Primary target
Multiple — modulates HPA axis + thalamic delta-wave generation (proposed)Schneider 1986
Intracellular targets bypassing melanocortin receptors (proposed)Dalle-Pang 2024
Pathway
Reduced cortisol/ACTH + enhanced delta-wave EEG activity → improved sleep onset + depthSchneider 1986
NF-κB inhibition + cytokine modulation (TNF-α, IL-1β, IL-6) → reduced inflammationDalle-Pang 2024
Downstream effect
Faster sleep onset, increased delta sleep, reduced stress response, possible anxiolytic effectSchneider 1986
Anti-inflammatory action without α-MSH pigmentation effects; gut barrier protectionDalle-Pang 2024
Feedback intact?
No melanocortin receptor binding
Origin
Endogenous peptide first isolated from rabbit blood during delta sleep; synthesised exogenouslySchneider 1986
Synthetic tripeptide; the C-terminal Lys-Pro-Val residues of α-MSH (residues 11-13)Dalle-Pang 2024

05Administration Protocol

Parameter
DSIP
KPV
1. Reconstitution
Add 1–2 mL bacteriostatic water to vial.
Add 1 mL bacteriostatic water to vial per labelling.
2. Injection site
SQ — abdomen. Rotate sites.
SQ injection (acute), oral capsule (chronic / gut), topical for skin indications.
3. Timing
30–60 min pre-sleep.
Morning preferred; oral form taken with / before meals.
4. Storage
Lyophilised: room temp. Reconstituted: refrigerate ≤30 days.
Lyophilised: room temp, light-protected. Reconstituted: refrigerate ≤30 days.

06Stack Synergy

— no documented stacks
KPV
+ BPC-157
Strong
View BPC-157

KPV (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
