Epitalon reconstitution calculator.
Epitalon vials range from 10 mg to 50 mg, and amounts are discussed in whole milligrams, so the same target can read as anything from a few units to most of the syringe depending on which vial you bought.
Reference range often cited for Epitalon: 5000–10000 mcg, shown for orientation only, not a recommendation. Enter your own target below. Read the evidence →
Each unit on a 100u · 1.0 mL syringe ≈ 50 mcg of this solution.

More water → lower concentration → more units for the same amount.
What changes the math for Epitalon.
- 10 mg in 2 mL is 5,000 mcg/mL, so 5 mg is 100 units, a full syringe. A 50 mg vial in 5 mL is 10,000 mcg/mL, where the same 5 mg is 50 units.
- Epitalon is typically used in short courses rather than continuously, so doses per vial often exceeds what a single course needs.
- The published literature is largely from one research group, which the compound profile flags. The arithmetic here is independent of that.

Epitalon: research formats
Choose the format you are researching to see route-specific notes.
Primary research format. Short tetrapeptide; highly water-soluble.
Epitalon is a short tetrapeptide (Ala-Glu-Asp-Gly) sold as a 10 mg or 50 mg vial. It is highly water-soluble and reconstitutes easily in BAC water. Reconstituting 10 mg with 2.0 mL BAC water gives 5,000 mcg/mL.
FAQ.
How many units is 5 mg of epitalon?
On 10 mg in 2 mL (5,000 mcg/mL) it is 100 units, the whole barrel. Less water raises the concentration and shrinks the draw, which is usually preferable at this scale.
Should I mix the whole 50 mg vial at once?
Once mixed, the reconstituted stability window starts for the entire vial. If a course uses a fraction of it, that window rather than the peptide is what limits you.
Is epitalon's evidence base solid?
It comes overwhelmingly from a single group, which is not the same as independent replication. The compound profile grades it on that basis.
