01Mechanism of Action

Parameter
DSIP
Pancragen
Primary target
Multiple — modulates HPA axis + thalamic delta-wave generation (proposed)Schneider 1986
Pancreatic acinar and islet cell differentiation pathwaysKhavinson 2013
Pathway
Reduced cortisol/ACTH + enhanced delta-wave EEG activity → improved sleep onset + depthSchneider 1986
Transcription factor activation → Pdx1/Pax6/Pax4/Ptf1a/Foxa2/NKx2.2 upregulation → Cell differentiationKhavinson 2013
Downstream effect
Faster sleep onset, increased delta sleep, reduced stress response, possible anxiolytic effectSchneider 1986
Enhanced pancreatic beta-cell function, normalized insulin/C-peptide dynamics, improved glucose clearanceGoncharova 2014
Feedback intact?
Yes — preserves physiological glucose-insulin response
Origin
Endogenous peptide first isolated from rabbit blood during delta sleep; synthesised exogenouslySchneider 1986
Synthetic tetrapeptide derived from pancreatic tissue extracts (Khavinson bioregulator methodology)
Antibody development

05Administration Protocol

Parameter
DSIP
Pancragen
1. Reconstitution
Add 1–2 mL bacteriostatic water to vial.
Lyophilised tetrapeptide reconstituted in sterile saline or water per manufacturer protocol. Concentration not specified in literature.
2. Injection site
SQ — abdomen. Rotate sites.
Intramuscular injection. Primate studies used daily IM dosing for 10 consecutive days.Goncharova 2015
3. Timing
30–60 min pre-sleep.
No specific timing constraints documented. Administered once daily in primate protocols.
4. Storage
Lyophilised: room temp. Reconstituted: refrigerate ≤30 days.
10-day treatment course. Restorative effects on pancreatic function persist for at least 3 weeks post-discontinuation.Goncharova 2014
5. Needle
29–31G insulin syringe.
