01Mechanism of Action

Parameter
DSIP
N-Acetyl Epitalon Amidate
Primary target
Multiple — modulates HPA axis + thalamic delta-wave generation (proposed)Schneider 1986
DNA promoter regions (telomerase, RNA polymerase II, retinal genes)
Pathway
Reduced cortisol/ACTH + enhanced delta-wave EEG activity → improved sleep onset + depthSchneider 1986
Peptide → DNA complementary binding → Gene transcription initiation → Telomerase catalytic subunit expression
Downstream effect
Faster sleep onset, increased delta sleep, reduced stress response, possible anxiolytic effectSchneider 1986
Telomerase enzymatic activity induction, telomere elongation to early-passage length, extension of replicative lifespan in human somatic cellsKhavinson 2003Khavinson 2004
Feedback intact?
Origin
Endogenous peptide first isolated from rabbit blood during delta sleep; synthesised exogenouslySchneider 1986
Synthetic tetrapeptide (Ala-Glu-Asp-Gly) derived from pineal extract bioregulator research; N-acetyl and C-amide modifications enhance plasma stability
Antibody development

02Dosage Protocols

Parameter
DSIP
N-Acetyl Epitalon Amidate
Standard dose
100–200 mcg SQ pre-sleepSchneider 1986
No standardized human dosing in indexed literature
In vitro protocols use direct culture addition; human clinical dosing protocols are in Russian-language literature outside PubMed scope.
Frequency
Once daily, pre-sleep
Not specified in candidate papers
Lower / starter dose
50 mcg pre-sleep
Evidence basis
Human-mechanistic + early clinicalSchneider 1986
In vitro human cell cultureKhavinson 2004Khavinson 2003
Duration
8–12 weeks per cycle
Chronic treatment in aging culture
Sustained effect through late passages.
Reconstitution
Bacteriostatic water
Timing
30–60 min pre-sleep
Half-life
Short plasma; CNS effects last hours
Cell culture protocol
Addition to human fetal fibroblast culture induced telomerase activity and telomere elongation to early-passage lengthKhavinson 2004
Cells made 10 extra divisions (44 passages total vs 34 in control).
Modification stability
N-acetyl + C-amide caps enhance peptidase resistance
Standard strategy for tetrapeptide stabilization; specifics not quantified in candidates.

Absolute Contraindications
DSIP
  • ·Pregnancy / breastfeeding
  • ·Concurrent CNS-depressant therapy without supervision
N-Acetyl Epitalon Amidate
  • ·Active malignancy or history of cancer — telomerase reactivation may promote tumor cell immortalization
Relative Contraindications
DSIP
  • ·Severe sleep apnoea (untreated)
  • ·Concurrent benzodiazepine / opioid use
N-Acetyl Epitalon Amidate
  • ·Individuals with hereditary cancer syndromes or high genetic cancer risk

05Administration Protocol

Parameter
DSIP
N-Acetyl Epitalon Amidate
1. Reconstitution
Add 1–2 mL bacteriostatic water to vial.
Subcutaneous injection assumed based on peptide class; no specific protocol in candidate papers.
2. Injection site
SQ — abdomen. Rotate sites.
Standard bacteriostatic water for lyophilized peptides. Exact volume not specified in indexed literature.
3. Timing
30–60 min pre-sleep.
Lyophilized: -20 °C, desiccated. Reconstituted: refrigerate 2–8 °C. N-acetyl and C-amide modifications improve stability vs unprotected tetrapeptide.
4. Storage
Lyophilised: room temp. Reconstituted: refrigerate ≤30 days.
Human dosing schedules published in Russian-language clinical literature; not indexed in PubMed candidate set.
5. Needle
29–31G insulin syringe.

06Stack Synergy

DSIP
— no documented stacks
N-Acetyl Epitalon Amidate
+ Thymalin
Moderate
View Thymalin

Both are Khavinson-school bioregulators with epigenetic mechanisms. Thymalin targets thymic transcription factors for immune function, while Epitalon targets telomerase and pineal-axis genes. Combined use theoretically addresses dual axes of aging: replicative senescence and immune decline. Multi-target bioregulator strategy per Khavinson gerontology framework.
