Epithalon Dosage Calculator

Epithalon (Epitalon) is supplied in 10 mg and 50 mg lyophilised vials. Research protocols typically run short courses of milligram-scale draws, so concentration matters more than doses-per-vial here.

The formula

Concentration (mg/mL) = vial strength (mg) ÷ bacteriostatic water (mL). Draw volume (mL) = dose (mg) ÷ concentration (mg/mL). On a U-100 insulin syringe, units = draw volume (mL) × 100. For Epithalon: a 10 mg vial in 2 mL of water is 5 mg/mL, so a 5 mg dose is 1 mL — 100 units.

How to reconstitute a Epithalon vial

  1. 1. Bring the vial to room temperature. Let a refrigerated or frozen vial equilibrate before opening so condensation doesn't form on the powder.
  2. 2. Swab both stoppers. Wipe the Epithalon vial and the bacteriostatic water vial with alcohol and let them dry.
  3. 3. Draw your diluent. Pull the volume you entered above into the syringe.
  4. 4. Run it down the glass wall. Angle the needle so water flows down the side of the vial rather than jetting onto the peptide cake — shear and foaming degrade peptides.
  5. 5. Swirl, never shake. Roll the vial gently until fully clear. Do not vortex or shake.
  6. 6. Label and refrigerate. Mark the date and concentration, then store at 2-8 °C away from light.

Epithalon calculator FAQs

How many units is 10 mg of epithalon from a 50 mg vial?

A 50 mg vial with 5 mL of bacteriostatic water is 10 mg/mL, so 10 mg is 1.0 mL — 100 units, a full U-100 syringe, with 5 draws per vial.

How do you calculate a Epithalon dose in syringe units?

Divide the vial strength by the bacteriostatic water you added to get the concentration: concentration (mg/mL) = vial mg ÷ water mL. Then draw volume (mL) = dose (mg) ÷ concentration. On a U-100 insulin syringe, 1.0 mL is 100 units, so units = draw volume × 100.

Does adding more water change how much Epithalon is in the vial?

No. The vial holds a fixed mass of lyophilised powder. More bacteriostatic water only dilutes it — each syringe unit carries less compound and the draw volume for the same dose gets larger, which can make small doses easier to measure accurately.

How is reconstituted Epithalon stored?

After reconstitution with bacteriostatic water, research peptides are kept refrigerated at 2-8 °C, protected from light, and away from freeze-thaw cycles. Unreconstituted lyophilised vials are far more stable and are typically stored frozen.
