Epithalon peptide calculator
A 10 mg Epithalon vial mixed with 2 ml of bacteriostatic water holds 5 mg/ml. A 5 mg dose is 1.00 ml — 100 units on a U-100 insulin syringe — and the vial holds 2 doses of that size.
Epithalon dosage chart: units to draw
Units on a U-100 insulin syringe (100 units = 1 ml) for Epithalon doses from 2.5 mg to 10 mg, by how much bacteriostatic water is in a 10 mg vial. The highlighted row is the 5 mg dose used above.
| Dose | 1 ml water 10 mg/ml | 2 ml water 5 mg/ml | 3 ml water 3.33 mg/ml | Doses per vial |
|---|---|---|---|---|
| 2.5 mg | 25 u 0.25 ml | 50 u 0.50 ml | 75 u 0.75 ml | 4 |
| 5 mg | 50 u 0.50 ml | 100 u 1.00 ml | 1.50 ml over 100 u | 2 |
| 7.5 mg | 75 u 0.75 ml | 1.50 ml over 100 u | 2.25 ml over 100 u | 1 |
| 10 mg | 100 u 1.00 ml | 2.00 ml over 100 u | 3.00 ml over 100 u | 1 |
A 100-unit draw needs a full 1 ml insulin syringe (100-unit capacity). Using less water concentrates the vial and shrinks the draw.
Unit math only, not a dosing recommendation. The dose range is what published protocols and trials describe; see the Epithalon guide for sources.
How to reconstitute Epithalon
- Wipe both vial stoppers with a fresh alcohol swab and let them dry.
- Draw 2 ml of bacteriostatic water into a syringe.
- Insert the needle at an angle into the Epithalon vial and let the water run slowly down the inner wall — do not inject directly onto the powder.
- Do not shake. Gently swirl the vial until the peptide fully dissolves.
- Storage for Epithalon: Lyophilized refrigerated. Reconstituted: refrigerated, use within 28 days.
- For a 5 mg dose, draw to the 100-unit mark (1.00 ml) on a U-100 insulin syringe.
About Epithalon
Epithalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) derived from epithalamin, a pineal gland extract. It is studied primarily for telomerase activation and longevity effects.
Half-life: Short systemic half-life; biological effects reportedly longer
Typical dose range: 5–10 mg daily for short cycles (10–20 days), typically 2x yearly
Class: Tetrapeptide / telomerase activator
Regulatory status: Not FDA approved. Research use only.

The peptide dose converter moves a dose between mcg, mg and IU, and the Epithalon half-life chart shows how concentration accumulates across a dosing cadence. Loading Epithalon into a reusable 3 ml pen instead of drawing it with a syringe? The peptide pen calculator turns the same vial into mcg per click and clicks to dial. All of them are listed on the free peptide tools page.
Epithalon calculator FAQ
Is this a Epithalon peptide calculator or a reconstitution calculator?
Both. This Epithalon calculator converts vial strength, bacteriostatic-water volume, and target dose into milliliters and insulin-syringe units. It does not recommend a medical dose.
How much bacteriostatic water for a 10 mg Epithalon vial?
This page is pre-filled with 2 ml of bacteriostatic water for a 10 mg Epithalon vial because that is a common research ratio. You can adjust the water amount in the full calculator.
How many units is a 5 mg Epithalon dose?
100 units on a U-100 insulin syringe, when a 10 mg vial is mixed with 2 ml of bacteriostatic water (5 mg/ml). That is 1.00 ml. With a different amount of water the unit count changes — the dose chart on this page lists 1 ml, 2 ml, 3 ml mixes.
How many doses are in a 10 mg Epithalon vial?
2 doses of 5 mg. The number of doses depends only on vial strength and dose size — adding more or less water changes the volume of each draw, not how many draws the vial holds.
Does this Epithalon dosage calculator give medical advice?
No. It only performs unit math. Dosing, titration, and whether Epithalon is appropriate are clinical decisions that should be made with a licensed healthcare professional.
