01Mechanism of Action

Parameter
DSIP
GHRP-6
Primary target
Multiple — modulates HPA axis + thalamic delta-wave generation (proposed)Schneider 1986
Ghrelin receptor (GHS-R1a)Bowers 1990
Pathway
Reduced cortisol/ACTH + enhanced delta-wave EEG activity → improved sleep onset + depthSchneider 1986
GHS-R1a → Gαq → Ca²⁺ → GH release; central appetite driveBowers 2002
Downstream effect
Faster sleep onset, increased delta sleep, reduced stress response, possible anxiolytic effectSchneider 1986
GH pulse + strong appetite stimulation; modest IGF-1 elevationBowers 2002
Feedback intact?
Origin
Endogenous peptide first isolated from rabbit blood during delta sleep; synthesised exogenouslySchneider 1986
Synthetic hexapeptide; first-generation GHRP from Bowers groupBowers 1990

05Administration Protocol

Parameter
DSIP
GHRP-6
1. Reconstitution
Add 1–2 mL bacteriostatic water to vial.
Add 2 mL bacteriostatic water to 5 mg vial → 2.5 mg/mL.
2. Injection site
