Research cycle phases
Units and volumes recompute from your Step 1 concentration (2 mL BAC → 5.00 mg/mL · 50.0 mcg/unit). Doses below are once daily during the course — not weekly.
Standard course
Common research-community range ~1–10 mg once daily for 10–20 day courses; many tables use ~5 mg/day, some clinic write-ups use ~10 mg nightly for 10 days. Cycles are often repeated only a few times per year after months off.
| Phase | Daily dose | Units | Volume |
|---|---|---|---|
| Days 1–5 (optional intro) | 2.50 mg2,500 mcg | 50 u | 0.50 mLLower daily amount while checking injection-site tolerance |
| Days 6–20 (standard course) | 5 mg5,000 mcg | 100 u | 1.00 mL5 mg daily is a frequently cited research-community amount |
Alternate / higher courses
Shorter or higher daily courses discussed in research communities — not a clinical recommendation

Epithalon 10 mg vials
9 vials
~87.5 mg mg total peptide over this 20-day course at 2.5 mg → 5 mg per injection (phase ladder). Each vial holds 10 mg.
Bacteriostatic water
6 × 3 mL or 2 × 10 mL
2 mL BAC per vial × 9 vials = 18.0 mL total. Buy as 6× 3 mL bottles or 2× 10 mL bottles (whichever you stock).
U-100 insulin syringes (100-unit)
20+ syringes
About one 100-unit syringe per injection for this schedule. Keep a few spares.
Alcohol swabs & sharps

Wipe vial stopper and injection site each time. Dispose needles in a proper sharps container.
Reconstitution steps
- Allow the lyophilized 10 mg Epithalon vial and bacteriostatic water to reach room temperature.
- Draw 2.0 mL bacteriostatic water (default). For denser draws, 1.0 mL is also used (10 mg/mL).
- Inject BAC slowly down the inner wall of the vial — avoid blasting the powder cake.
- Gently swirl or roll until the solution is clear. Do not shake hard (foaming).
- Label with recon date and concentration (e.g. "5.0 mg/mL — 2 mL BAC").
- Refrigerate at 2–8 °C (35–46 °F), protected from light. Prefer using a reconstituted vial within the short course window (~2–4 weeks).
Storage
Lyophilized
Keep dry powder cold and dark when possible (−20 °C / −4 °F preferred for long-term research stock).
Reconstituted
Refrigerate at 2–8 °C (35–46 °F). Avoid freeze–thaw of the working solution. Finish within the active course when practical.
- ·Short courses mean most of a vial is used quickly — plan daily draws so leftover reconstituted solution is minimal.
- ·Protect from light; pineal bioregulator peptides are often handled as light-sensitive research materials.
- ·Write recon date and BAC volume on the label.
Protocol notes
- ·This is a cyclic daily peptide in research discussions — not a once-weekly GLP-1-style titration.
- ·Typical framing: inject once daily for 10 or 20 consecutive days, then stop for months.
- ·Secondary sources often mention ~1–4 courses per year with long off intervals.
- ·Rotate subcutaneous sites.
- ·Research use only. Not a substitute for medical care.
Research context & considerations
Epithalon (also spelled Epitalon; sequence Ala-Glu-Asp-Gly) is a synthetic tetrapeptide associated with pineal bioregulator research. This page is a reconstitution and unit-math aid for research logistics only.
- ·Injection-site irritation is the most practical day-to-day issue.
- ·Not FDA-approved for any indication.
- ·Active malignancy or serious endocrine disease should not be self-managed with research peptides.
- ·Pregnancy, breastfeeding, and pediatric use are outside research-hobby scope.
