Quick math example
A 20 mg vial mixed with 2 mL gives 10 mg/mL. A 5 mg dose is 0.5 mL, which equals 50 units on a U-100 syringe.
How the Epithalon calculation works
Epithalon vials are commonly labelled in milligrams. Concentration is found by dividing the vial total by your BAC water volume; the draw volume is your target dose divided by that concentration.
Cycle protocols often involve daily dosing for short windows, so saving the calculated draw amount avoids repeated math.
- 20 mg vial = 20,000 mcg total
- 20,000 mcg / 2 mL = 10,000 mcg per mL
- 5,000 mcg target = 0.5 mL draw
Track reconstitution date and doses remaining
Once a vial is reconstituted, beyond-use dates and storage become part of the protocol. PepSync stores reconstitution date alongside the calculator inputs so you do not lose track between doses.
Frequently asked questions
Is Epithalon approved as a medicine?+
Approval status varies by jurisdiction. This page only covers calculator math; for legal and clinical status, check current regulatory guidance.
How do I handle a higher-concentration Epithalon vial?+
Enter the actual mg amount and BAC water volume. Higher concentration means smaller draw volumes for the same target dose, which can be easier to read on a U-100 syringe.
Does the calculator track cycle progress?+
The calculator returns a per-dose draw. Cycle and schedule tracking sit inside the PepSync app, where the protocol view stays updated as doses are logged.
