Enter your Epitalon (Epithalon) vial size and the volume of bacteriostatic water you are adding. The calculator returns the concentration in mcg/ml and the exact units to draw on a U-100 insulin syringe. It works for the common 10mg and 50mg vials.

How this is calculated
50mg × 1,000 = 50000 mcg total
50000 ÷ 5ml = 10000 mcg/ml
10000 mcg ÷ 10000 = 1 ml
1 ml × 100 = 100 units

Epitalon is a tetrapeptide researched for its effects on the pineal gland and circadian rhythm, typically run in short cycles of daily doses rather than continuously. Because the daily dose is large (often 5–10mg), a bigger vial and more BAC water keep the injection volume workable.
Reflects the short-cycle daily dosing commonly reported for Epitalon. It is usually injected subcutaneously.
| Common cycle dose | 5–10 mg (5,000–10,000 mcg) once daily |
| Cycle length | typically a 10–20 day cycle, repeated periodically |
Worked example: 50mg vial + 5ml BAC water, 10mg dose
5ml gives 10,000 mcg/ml, so a 10mg dose is exactly 1ml = 100 units (a full U-100 syringe). If you prefer a smaller injection, a 10mg vial in 2ml gives 5,000 mcg/ml and a 5mg dose becomes 1ml = 100 units.
With a 50mg vial reconstituted in 5ml (10,000 mcg/ml): 10,000 ÷ 10,000 = 1.0ml = 100 units. Enter your vial size and water volume above to match your setup.
Epitalon is typically run in short cycles — for example a daily dose for 10–20 days, repeated a few times a year — rather than continuously. Reconstitute with the length of your cycle in mind so the vial is used within its shelf life.
Refrigerate at 2–8°C away from light and label the vial with the date. Reconstituted Epitalon is commonly used within 2–4 weeks. Do not freeze it.
Store your vial concentration, log every dose against it, and never lose track of what you injected or when.
