01Mechanism of Action
Parameter
Epitalon
Semaglutide
Primary target
Telomerase activity (proposed); pineal melatonin axis modulationKhavinson 2003
GLP-1 receptor (GLP-1R)WEGOVY (semaglutide) injection 2021
Pathway
Activation of telomerase reverse transcriptase (hTERT) in somatic cells; pineal-axis modulation supports endogenous melatoninKhavinson 2003
GLP-1R agonism → ↑glucose-dependent insulin secretion, ↓glucagon, ↓gastric emptying, ↓appetite via hypothalamic centresWilding 2021
Downstream effect
Telomere elongation, improved sleep architecture, reported lifespan extension in aged miceKhavinson 2003
Improved glycemic control, reduced caloric intake, body-weight reduction, cardiovascular risk reductionWilding 2021
Feedback intact?
—
Glucose-dependent insulin release preserves physiological feedback
Origin
Synthetic 4-AA peptide derived from epithalamin (a natural pineal extract)Khavinson 2003
Modified GLP-1(7-37) with two amino-acid substitutions and C-18 fatty-acid acylation for albumin binding and 168-h half-lifeWEGOVY (semaglutide) injection 2021

05Administration Protocol
Parameter
Epitalon
Semaglutide
1. Reconstitution
Add 1–2 mL bacteriostatic water to 10 mg vial → 5–10 mg/mL.
Commercial: pre-filled pen, no reconstitution. Research vial: per-label or bacteriostatic water.
2. Injection site
SQ — abdomen preferred. Rotate sites.
SQ — abdomen, thigh, or upper arm. Rotate sites weekly to avoid lipohypertrophy.
3. Timing
Pre-sleep preferred to align with pineal axis.
Once weekly, same day. Day can be changed if ≥2 days separate doses.
4. Storage
Lyophilised: room temp, light-protected. Reconstituted: refrigerate ≤30 days.
Pen: refrigerate 2–8 °C unopened; room temp ≤30 °C up to 56 days after first use.
5. Needle
29–31G, 4–8 mm insulin syringe.
Pen-supplied 31–34G needle. Research vial: 27–31G insulin syringe.
06Stack Synergy
Epitalon
— no documented stacks
Semaglutide
+ Tirzepatide
WeakCombining two GLP-1 RA-class drugs is not clinically validated and risks additive GI toxicity. Tirzepatide's GIP component already provides complementary mechanism vs pure GLP-1; stacking with semaglutide adds receptor saturation but no synergy. NOT recommended.
- Note
- Stack not recommended — choose one GLP-1 RA
- Primary benefit
- (none — additive toxicity, no synergy)
