01Mechanism of Action
Parameter
DSIP
Testagen
Primary target
Multiple — modulates HPA axis + thalamic delta-wave generation (proposed)Schneider 1986
Testicular tissue; proposed nuclear DNA interaction
Pathway
Reduced cortisol/ACTH + enhanced delta-wave EEG activity → improved sleep onset + depthSchneider 1986
Nuclear penetration → DNA/oligonucleotide binding → gene expression modulation (bioregulator hypothesis)Fedoreyeva 2011
Downstream effect
Faster sleep onset, increased delta sleep, reduced stress response, possible anxiolytic effectSchneider 1986
Proposed support for spermatogenesis and testicular function; mechanistic data limited to nuclear localization and DNA interactionFedoreyeva 2011
Feedback intact?
—
Unknown — no HPG axis data
Origin
Endogenous peptide first isolated from rabbit blood during delta sleep; synthesised exogenouslySchneider 1986

05Administration Protocol
Parameter
DSIP
Testagen
1. Reconstitution
Add 1–2 mL bacteriostatic water to vial.
Add 1–2 mL sterile or bacteriostatic water to lyophilised vial. Swirl gently; do not shake. Solution should be clear.
2. Injection site
SQ — abdomen. Rotate sites.
Subcutaneous — abdomen or thigh. Rotate sites daily. Use standard insulin syringe (27–31G).
3. Timing
30–60 min pre-sleep.
Morning or evening; no established optimal timing. Anecdotal preference: evening to align with circadian testosterone patterns.
4. Storage
Lyophilised: room temp. Reconstituted: refrigerate ≤30 days.
Lyophilised: room temp, dark. Reconstituted: refrigerate 2–8 °C, use within 14–21 days if bacteriostatic water used.
5. Needle
29–31G insulin syringe.
10–20 days on, 10–14 days off. Bioregulator tradition uses pulsed exposure; rationale: prevent receptor/pathway desensitisation.
