How many units is each Epithalon amount?
At 10 mg + 2 mL (5 mg/mL) on a U-100 syringe:
Generated from the calculator's own functions. Rows are evenly spaced reference amounts, not suggested amounts. Amber readings don't fit a 100-unit barrel.
| Amount | mcg | Volume (mL) | Syringe units |
|---|---|---|---|
| 0.5 mg | 500 | 0.1 | 10 |
| 1 mg | 1,000 | 0.2 | 20 |
| 2 mg | 2,000 | 0.4 | 40 |
| 2.5 mg | 2,500 | 0.5 | 50 |
| 5 mg | 5,000 | 1 | 100 |
| 10 mg | 10,000 | 2 | 200 (> 100) |

How much water for each Epithalon vial size?
Epithalon is sold in 2 common sizes (10 mg, 50 mg). The same water volume gives a different concentration in each, so the same reading means a different amount. Each cell shows mcg per unit with mg/mL in brackets.
| Vial | 1 mL | 2 mL | 3 mL | 5 mL |
|---|---|---|---|---|
| 10 mg | 100 (10) | 50 (5) | 33.33 (3.33) | 20 (2) |
| 50 mg | 500 (50) | 250 (25) | 166.7 (16.67) | 100 (10) |
How much bacteriostatic water for a 10 mg Epithalon vial?
1 mL → 10 mg/mL, so 1 mg is 10 units. 2 mL → 5 mg/mL, so 1 mg is 20 units. 3 mL → 3.33 mg/mL, so 1 mg is 30 units. The whole vial holds 10 draws of 1 mg.
How much bacteriostatic water for a 50 mg Epithalon vial?
1 mL → 50 mg/mL, so 1 mg is 2 units. 2 mL → 25 mg/mL, so 1 mg is 4 units. 3 mL → 16.67 mg/mL, so 1 mg is 6 units. The whole vial holds 50 draws of 1 mg.
Worked example: 10 mg vial, 2 mL, 1 mg
- Concentration. 10 mg ÷ 2 mL = 5 mg/mL (5,000 mcg/mL).
- Volume. 1 mg ÷ 5 mg/mL = 0.2 mL.
- Units. 0.2 mL × 100 = 20 units on a U-100 syringe.
- Check. One unit holds 50 mcg; 20 × 50 mcg = 1,000 mcg = 1 mg, which matches. The vial holds 10 draws of this size.
Epithalon: notes for the arithmetic
Epithalon is listed in both 10 mg and 50 mg vials. A 50 mg vial with 2 mL is 25 mg/mL, five times stronger than a 10 mg vial with the same water.
For the lab procedure itself (materials, aseptic technique, mixing without foaming) see how to reconstitute peptides. For what bacteriostatic water is and how long an opened vial is kept, see the bacteriostatic water guide and the storage guide.
Frequently asked questions
How many units is 1 mg of Epithalon?
It depends on the water volume. 10 mg + 2 mL = 5 mg/mL, so 1 mg is 0.2 mL, or 20 units on a U-100 syringe. With 1 mL instead it would be 10 units.
How much bacteriostatic water for a 10 mg Epithalon vial?
There is no single correct volume. 1 mL gives 10 mg/mL (100 mcg per unit); 2 mL gives 5 mg/mL (50 mcg per unit); 3 mL gives 3.33 mg/mL (33.33 mcg per unit). Pick the volume that makes your reading easy to measure on the barrel you have.
How much bacteriostatic water for a 50 mg Epithalon vial?
There is no single correct volume. 1 mL gives 50 mg/mL (500 mcg per unit); 2 mL gives 25 mg/mL (250 mcg per unit); 3 mL gives 16.67 mg/mL (166.7 mcg per unit). Pick the volume that makes your reading easy to measure on the barrel you have.
How many mg of Epithalon is 10 units?
10 units on a U-100 syringe is 0.1 mL. At 5 mg/mL (10 mg in 2 mL) that is 0.5 mg (500 mcg). At a different concentration the answer is different.
Is this a Epithalon dosing calculator?
It is an arithmetic tool. It converts an amount you enter into a volume and a syringe reading; it does not suggest amounts, schedules or uses. Not approved by the FDA for any use. Sold as a research chemical only.
