What is Epitalon?

What the compound is

Epitalon is a short synthetic peptide, grouped commercially under the longevity label. It is supplied as a freeze dried powder in a sealed vial. The powder has no volume you can measure with a syringe, so it has to be dissolved in a liquid before any portion of it can be drawn out. That liquid is normally bacteriostatic water.

That is the whole reason a concentration table exists. The vial tells you a mass. The syringe reads a volume. Reconstitution is the step that converts one into the other, and the conversion factor is whatever concentration you created when you added the water.

This site is a dose-arithmetic reference. It divides milligrams by milliliters. It has no medical review, it does not evaluate the compound, and nothing here should be read as a recommendation to use it.

Regulatory status

Epitalon is not approved by any regulator for human use. There is no approved label, no approved indication, and no approved dose. Material sold under this name is sold for research purposes, and the manufacturing, purity, and actual mass in the vial are outside anything this page can verify.

That matters for the arithmetic in a specific way. Every calculation on this page assumes the vial contains the mass printed on it. If it does not, the computed concentration is wrong by the same margin, and there is no way to detect that from the outside of the vial.

Because there is no approved label, there is also no authoritative source that says what quantity is appropriate. The dose amounts listed by sellers, 5 mg and 10 mg, are figures that appear in listings. They are not endorsements, and this page will not tell you which, if either, to use.

What is not known

There is no reliable human pharmacokinetic data for Epitalon. This site therefore makes no claim about its half life, how quickly it clears, whether it accumulates with repeated use, or how long any effect might persist.

That gap is larger than it may look. Pharmacokinetics is what lets anyone reason about spacing doses, about whether daily and weekly schedules differ in any meaningful way, and about what a given concentration in the vial actually translates to inside a body. Without that data, none of those questions have answers here.

What remains is concentration and volume. Those are pure arithmetic and do not depend on biology. They are correct regardless of what the compound does or does not do, which is precisely why they are the only thing this page computes.

Reading the concentration table

Three vial sizes are sold, 10 mg, 20 mg and 50 mg, and three water volumes are in common use, 1 mL, 2 mL and 3 mL. The table above crosses them. Three things in it are worth pulling out.

First, the same concentration can come from different vials. A 10 mg vial in 1 mL and a 20 mg vial in 2 mL both give 10 mg/mL. The larger vial does not produce a stronger solution, it produces more of the same solution. Vial size determines how many doses you get, not how strong each milliliter is.

Second, the spread is wide. The table runs from 3.33 mg/mL at the low end to 50 mg/mL at the high end. That is a large factor between the weakest and strongest cell. A syringe mark that means one thing at 3.33 mg/mL means something very different at 50 mg/mL, so the vial label alone tells you nothing useful without the water volume written down next to it.

Third, the 3 mL column produces repeating decimals: 3.33 mg/mL, 6.67 mg/mL and 16.67 mg/mL. These are rounded values. Whole number concentrations, such as 10 mg/mL or 25 mg/mL, make the subsequent division easier and leave less room for a rounding slip when you go from a mass to a syringe volume.

From concentration to volume

Once the concentration is fixed, the working step is a single division. Take the mass you intend to draw, divide it by the concentration in mg/mL, and the result is the volume in milliliters. That is the only operation involved.

The listed dose amounts of 5 mg and 10 mg divide cleanly against some concentrations in the table and awkwardly against others. Choosing a water volume that produces a round concentration relative to the mass you care about reduces the arithmetic to something you can check in your head, which is worth more than it sounds when you are reading small marks on a barrel.

Write the water volume on the vial as soon as you add it. The reconstituted liquid looks identical whether it is 5 mg/mL or 25 mg/mL. The only record of which one you made is the number you wrote down, and that number is what every later calculation depends on.

What we do not know

We hold no reliable human pharmacokinetic data for Epitalon, so this site makes no claims about its half life, how long it takes to clear, or how it accumulates. The arithmetic below concerns concentration and volume only.

This page answers arithmetic and handling questions. It does not tell you what dose to take, what to expect, or whether anything is appropriate for you, and there is no medical review behind it.

Common questions

How much bacteriostatic water should I add to an Epitalon vial?

There is no correct answer that applies to everyone, and this site will not pick one for you. The three volumes in common use are 1 mL, 2 mL and 3 mL, and the table shows what concentration each produces from a 10, 20 or 50 mg vial. The choice is an arithmetic convenience, not a clinical decision.

Does a bigger vial mean a stronger dose?

No. A 20 mg vial in 2 mL and a 10 mg vial in 1 mL both give 10 mg/mL. The larger vial holds more total material, so it yields more doses at the same strength. Concentration depends on the ratio of mass to water, not on the vial size alone.

Is Epitalon approved for human use?

No. It is not approved by any regulator for human use. There is no approved label, indication or dose, and material sold under this name is sold for research purposes.

How long does Epitalon stay in the body?

We hold no reliable human pharmacokinetic data for Epitalon, so this site makes no claim about its half life, clearance or accumulation. Any specific duration figure you encounter did not come from this page. The arithmetic here concerns concentration and volume only.

What dose of Epitalon should I take?

This page does not answer that. It has no medical review and does not make clinical recommendations. The amounts of 5 mg and 10 mg appear in seller listings, which is a description of the market, not guidance.

Why do some concentrations have repeating decimals?

Because the vial mass does not divide evenly into the water volume. The 3 mL column gives 3.33 mg/mL, 6.67 mg/mL and 16.67 mg/mL, all rounded. Whole number concentrations such as 5, 10, 20, 25 or 50 mg/mL make the later division simpler and reduce rounding error.
