U-100 insulin syringe · 1 mL · lines every 2 units · 1 unit = 0.01 mL
Draw to
10.0units
10.0 units on a U-100 insulin syringe · 1 mL · lines every 2 units, which is 0.10 milliliters. The draw lands on a syringe line.
10 mg ÷ 2 mL = 5.00 mg/mL
→ 50 mcg/unit · 0.5 mg = 0.100 mL = 10.0 units
→ 50 mcg/unit · 0.5 mg = 0.100 mL = 10.0 units

Epitalon is a peptide four amino acids long, made in Leningrad in the 1980s. It copies the amino-acid makeup of an extract of cow pineal gland. It is sold for longevity — longer telomeres, better sleep, slower aging.
The lifespan results people quote were produced by the gland extract, not by this peptide. One monkey experiment ran both side by side and used five hundred times more of the extract. Two human studies of the peptide itself exist. They measured eyesight and a urine marker, and both came out of the institute that made it.
Examples using 10 mg of Epitalon
Each row uses 10 mg and the liquid volume shown. Dividing the amount by that volume gives the calculated concentration. The rows are arithmetic examples, not alternative product preparations.

The amount, liquid volume and dose shown here are the calculator’s starting example for Epitalon. Replace them with your own values. Every result in the table is calculated from those inputs.
Epitalon: keep the study route and substance with the amount
The epitalon guide describes human reports using different routes, including under the tongue and around the eye. Their amounts belong to those settings. A syringe conversion does not establish an equivalent amount for another route.

Different routes answer different questions
The under-the-tongue report and the eye-treatment report measured different outcomes in different groups. Their amounts are not interchangeable simply because both are expressed as a mass of epitalon.
The calculator works with the amount entered and the modeled concentration. It does not know which study a reader means or determine whether that study applies to a particular preparation. Keeping the source context beside the amount avoids losing those distinctions.
The opening examples land on syringe lines
At the default amount, all three water-volume presets produce whole marked readings on the modeled U-100 scale. That is a property of these particular inputs. Editing the amount or the syringe can change the rounding result.
Water changes the concentration and the liquid volume needed for the same mass. It does not change the theoretical number of equal draws in the vial. A whole-unit result also supplies no storage instructions or evidence of stability after mixing.
Epitalon and a gland extract are different preparations
The guide distinguishes the peptide from the gland extract discussed in some related research. A result attached to the extract cannot establish a dose for epitalon just because the names appear together.
The same care applies to vial information. The calculation needs the amount represented by the selected preset or entered value. Neither a similar name nor a remembered syringe reading verifies that amount. Uncertain product identity cannot be resolved by a more precise calculation.
Epitalon’s human quantities here are reported through a review
The cited review describes two human studies: one gave Epitalon under the tongue, and another placed it near the eye. Their routes and treatment goals differ. Neither report establishes a routine injection schedule.

The eye-study amount was given per eye
A quantity placed near an eye for a retinal condition is not a whole-body dose. The treatment site and per-eye basis cannot be dropped simply because the mass can be expressed in syringe units.
The sublingual course answers a different question
The other study examined markers related to daily biological rhythms. A quantity used under the tongue does not establish an equivalent injection amount. Its findings also do not establish a general longevity outcome.
Laboratory effects do not provide a personal schedule
The broader literature includes cells and animal experiments. A finding about an enzyme or a gene is not a tested treatment course for a person. The tool retains the boundary between a reported amount and an established use.

Units to dose at 5.00 mg/mL
Mix 10 mg into 2 mL and one U-100 unit carries 50.0 mcg. The table shows how much peptide is in each numbered syringe line. These are conversion examples, not suggested doses.

How the math works
- Concentration — divide the amount entered by the liquid volume used in the calculation: mg ÷ mL = mg/mL. This tells you how many mg are in each mL.
- Volume — the dose divided by that concentration: dose ÷ (mg/mL) = mL.
- Units — on a U-100 syringe one unit is 0.01 mL, so mL × 100 = units. A U-40 unit is 0.025 mL, so the wrong barrel is a 2.5× error. That is why the calculator asks which one you have.
- Rounding gap — the exact draw against the nearest syringe line: |exact − nearest line| ÷ exact × 100 = % difference.
