Epithalon dosage calculator
The Epithalon dosage calculator above converts a target dose into exact syringe units based on your vial size and how much bacteriostatic water you used to reconstitute it. Epithalon is commonly sold in 10 mg, 20 mg, 50 mg, 100 mg vials. The calculator supports both U-100 and U-40 insulin syringes and flags draws that are too large for the syringe barrel or too small to measure accurately. A synthetic tetrapeptide analog of the larger polypeptide epithalamin, studied for telomerase-related and circadian signaling mechanisms. Enter your target dose in the calculator above to see the exact number of units to draw.

| Sample dose | Concentration | Volume to draw | Units on U-100 |
|---|---|---|---|
| 0.88 mg | 10 mg/mL | 0.088 mL | 8.8 |
| 1.8 mg | 10 mg/mL | 0.18 mL | 18 |
| 3.5 mg | 10 mg/mL | 0.35 mL | 35 |
| 7 mg | 10 mg/mL | 0.7 mL | 70 |
| 14 mg | 10 mg/mL | 1.4 mL | 140 |

How to reconstitute Epithalon
Reconstituting Epithalon is the same unit-conversion process used for any lyophilized peptide:
- Draw your chosen volume of bacteriostatic water into a syringe.
- Inject the bacteriostatic water slowly down the side of the Epithalon vial — do not shoot it directly onto the powder.
- Swirl gently until the powder fully dissolves. Do not shake.
- Store the reconstituted vial refrigerated.
- To dose, calculate your draw volume: divide your target dose by the concentration (vial mg ÷ water mL = mg/mL). The calculator above does this automatically.
For Epithalon specifically, 10 mg, 20 mg, 50 mg, 100 mg vials are common. A typical reconstitution adds 2 mL of bacteriostatic water, producing a concentration of 25 mg/mL for the 50 mg vial size.
Epithalon half-life and storage
As a very short unmodified tetrapeptide, epithalon is expected to have a short plasma half-life on the order of minutes, though downstream effects measured in research models may persist longer.
Lyophilized epithalon is typically stored refrigerated or frozen. Reconstituted solutions are commonly refrigerated and protected from light.
Common Epithalon dosing mistakes
- Confusing mg and mcg. 1 mg = 1,000 mcg. Always convert to the same unit before computing the draw.
- Using a U-40 syringe with U-100 math. Same printed mark, 2.5× the physical volume. Always check the syringe label.
- Not labeling the vial. Write the reconstitution date and concentration on the vial the moment you mix it.
- Under-diluting. If your draw is less than about 1 unit, the volume is too small to read accurately — add more bacteriostatic water next time.
