Epithalon Reconstitution Calculator
Epithalon is a synthetic tetrapeptide (also spelled epitalon; one of the Khavinson bioregulators). This page shows how to reconstitute it and read the result on a syringe — the calculator does the arithmetic for you.
Status: Not approved for human use; sold as a research compound.
The math
Concentration = vial ÷ water · Units = (dose ÷ concentration) × 100
Epithalon (epitalon) reconstitutes in bacteriostatic water. Larger vials are common, so adjust your diluter volume to keep draws readable.

Frequently asked questions
How do I reconstitute Epithalon?
Add bacteriostatic water to the lyophilized vial to reach a concentration you can measure. For example, 10 mg in 2 mL of water gives 5 mg/mL, so each 10 units (0.1 mL) on a U-100 syringe contains about 500 mcg of Epithalon. Swirl gently rather than shaking.
How many units of Epithalon do I draw?
Divide your intended dose by the concentration to get the volume in mL, then multiply by 100 for a U-100 syringe. The calculator does this automatically once you enter your vial size, water volume and dose.
What vial sizes does Epithalon come in?
Epithalon is commonly supplied as 10 mg, 20 mg, 50 mg. The amount in the vial does not change with how much water you add — water only sets the concentration.
Is Epithalon approved for human use?
Not approved for human use; sold as a research compound. This calculator only performs arithmetic on the numbers you enter and does not recommend any dose.
