How many units is 5 mg of Epitalon?

It depends entirely on how much water you added. In a 10 mg vial reconstituted with 1 mL, the concentration is 10 mg/mL, so 5 mg is 0.5 mL, which is 50 units on a U-100 insulin syringe. In the same vial with 0.5 mL of water it is 25 units, and with 1.5 mL it is 75 units.

How much bacteriostatic water for a 10 mg Epitalon vial?

1 mL is the usual choice. It gives 10 mg/mL, which puts the commonly reported range of 1 mg to 10 mg between roughly 10 and 100 units. Aim for a draw between about 10 and 50 units, where the barrel is easiest to read, and add or remove water to get there.

How many doses are in a 10 mg vial?

Divide 10 by your dose. At 5 mg that is 2 doses, which at once daily is 2 days.

How many units is 5 mg of epitalon?

In a 10 mg vial with 1 mL of water, 50 units on a U-100 syringe. In a 50 mg vial with 5 mL, also 50 units.

Epitalon dosage calculator

Epitalon is dosed in whole milligrams for short courses. Enter your vial, water and dose to get the syringe mark, and note how fast a 10 mg vial goes at these doses.

About the numbers above

Epitalon (epithalon, AEDG) is a synthetic tetrapeptide based on epithalamin, a pineal extract studied in Russia. It is not an approved medicine and is sold for research use.

Reported protocols are unusual: 5 to 10 mg a day for 10 to 20 days, repeated once or twice a year, though lower daily doses are also reported. A 10 mg vial with 1 mL of water is 10 mg/mL, so 5 mg is 0.5 mL, or 50 units, and a 10 mg vial is two doses. At these doses a 50 mg vial is the practical size for a full course.

A 10 mg vial at different water volumes

If the draw feels awkward to read, change the water rather than the dose. The dose stays the same; only the mark moves.

Vial	BAC water	Concentration	Draw	U-100 units	Doses/vial
10 mg	1 mL	10 mg/mL	0.5 mL	50 units	2
10 mg	2 mL	5 mg/mL	1 mL	100 units	2
10 mg	3 mL	3.33 mg/mL	1.5 mL	150 units	2
20 mg	1 mL	20 mg/mL	0.25 mL	25 units	4
20 mg	2 mL	10 mg/mL	0.5 mL	50 units	4
20 mg	3 mL	6.67 mg/mL	0.75 mL	75 units	4

All rows above assume a 5 mg dose and a standard U-100 insulin syringe, where 100 units = 1 mL.

Not well characterised in humans. This site only draws a decay curve where a half-life is actually documented in humans, so there is none here. Treat any precise figure you see elsewhere for Epitalon with suspicion.

Common questions

How many units is 5 mg of Epitalon?: It depends entirely on how much water you added. In a 10 mg vial reconstituted with 1 mL, the concentration is 10 mg/mL, so 5 mg is 0.5 mL, which is 50 units on a U-100 insulin syringe. In the same vial with 0.5 mL of water it is 25 units, and with 1.5 mL it is 75 units.
How much bacteriostatic water for a 10 mg Epitalon vial?: 1 mL is the usual choice. It gives 10 mg/mL, which puts the commonly reported range of 1 mg to 10 mg between roughly 10 and 100 units. Aim for a draw between about 10 and 50 units, where the barrel is easiest to read, and add or remove water to get there.
How many doses are in a 10 mg vial?: Divide 10 by your dose. At 5 mg that is 2 doses, which at once daily is 2 days.
How many units is 5 mg of epitalon?: In a 10 mg vial with 1 mL of water, 50 units on a U-100 syringe. In a 50 mg vial with 5 mL, also 50 units.

Read this before you use the numbers. This is a unit-conversion tool. It converts a vial strength and a volume of bacteriostatic water into a concentration, a draw volume and a mark on an insulin syringe. It does not tell you what to take, whether to take it, or whether a compound is safe for you. Most of the compounds listed here are sold for laboratory research use and are not approved for human use. Nothing on this site is medical advice. Dosing decisions belong with a licensed clinician who knows your history. Always confirm the strength printed on your own vial rather than trusting a preset.
