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.

About Epitalon

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.

The same 10 mg vial at other water volumes

If the draw is awkward to read, change the water, not 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.

How long it lasts in the body

Not well characterised in humans. A decay curve is only drawn where a human half-life is documented, so there is none here. Treat any precise figure for Epitalon elsewhere with caution.

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