Where the daily number comes from
The epithalon dosage per day is 5 to 10 mg, once a day, injected under the skin. You'll see it on peptide education pages and vendor sites, which credit a research group in St. Petersburg, Russia, and it's the range our epithalon dosage page charts. No approved label sets it, and no human dose-finding study has compared one daily amount with another.
So the range is a convention, the amount people describe running, and both ends of it are in circulation. Where you land between 5 and 10 mg is the part nobody has tested.
The dosage here is really two things, the milligrams in each injection and the schedule around them. The schedule on those same pages is one injection a day for 10 days in a row, repeated 2 to 3 times a year, with a 20-day course at the same daily amount as a less common variant. A 10-day course adds up to 50 to 100 mg and a 20-day course to 100 to 200 mg, which is simple multiplication from the daily range.
What a day looks like in the vial
| Vial | At 5 mg a day | At 10 mg a day |
|---|---|---|
| 10 mg | 2 days | 1 day |
| 20 mg | 4 days | 2 days |
These vial lengths are the ones on the dosage page. A 10-day course adds up to 50 to 100 mg, which is 5 to 10 vials of 10 mg. A mixed vial keeps for 28 days in the fridge, and every vial in the table is used up in four days or fewer.
What it changes for your units
The milligrams per day stay the same, and the units on the syringe depend on how much bacteriostatic water, which is sterile water with a preservative so one vial can be drawn from more than once, went into the vial. With a 10 mg vial and 1 mL of water, 5 mg is 50 units and 10 mg is 100 units on a U-100 syringe, the kind that holds 100 units in 1 mL. More water makes each draw bigger and easier to read, and a draw over 100 units won't fit in one 1 mL syringe. How many units are in a 10 mg epithalon vial has the full table, and the reconstitution calculator does it for any other vial.
If you're planning an order, compare vendors on price per milligram against the milligrams a course needs, and see who's carrying epithalon today on the epithalon page. How many days the course runs is covered in how long an epithalon cycle is.
It's sold for research, and the big human trials haven't been run yet. You knew that, it's why you're reading this and not the label.
Questions people ask
How much epithalon per day?
5 to 10 mg, once a day, injected under the skin. Peptide education pages and vendor sites give that range, and no label or study sets it.
Is epitalon dosage per day the same as epithalon?
Yes. Epitalon is another spelling of the same peptide, so the daily amount is the same.
Can you take epithalon more than once a day?
No source we found describes more than one injection a day. Every pattern on education and vendor pages is one a day.
How many days do you take the daily dosage?
Ten days in a row is the standard course, repeated 2 to 3 times a year. A 20-day course at the same daily amount shows up less often.
How many vials is a day of epithalon?
A 10 mg vial covers one day at 10 mg or two days at 5 mg. A 20 mg vial covers two days at 10 mg or four days at 5 mg.
