What is Epitalon (Epithalon)?
Epithalon and Epitalon are two spellings of the same compound. It is a synthetic tetrapeptide, four amino acids long, with the sequence Ala-Glu-Asp-Gly, which is why it is sometimes labeled AEDG. It was developed in Russia by Vladimir Khavinson’s group, modeled on epithalamin, an extract of the pineal gland. The Epithalon 50mg vial is the size this page is built around, although 10 mg vials are also common.
If you are wondering what is Epitalon versus Epithalon, the answer is only transliteration. Labels, research papers, and supplier listings use both spellings, and some add the AEDG code. The compound, its molecular weight, and every calculation on this page are identical whichever name appears on your vial.
Research interest in Epithalon has centered on aging biology, including laboratory and animal studies of telomeres and telomerase. Most of that literature comes from a small number of research groups. Describing the research is not a claim about any effect in people, and this site makes none. Other longevity research compounds, such as FOXO4-DRI, are listed in the peptide library.
How much BAC water for an Epithalon 50mg vial?
A 50 mg vial carries five times the peptide of a 10 mg vial, so at the same water volume each syringe unit holds five times as many micrograms. The water volume sets the concentration; it never changes the milligrams in the vial. The chart compares both common sizes.
| BAC water | 10 mg vial | 50 mg vial |
|---|---|---|
| 1 mL | 100 mcg/unit 10 mg/mL | 500 mcg/unit 50 mg/mL |
| 2 mL | 50 mcg/unit 5 mg/mL | 250 mcg/unit 25 mg/mL |
| 3 mL | 33.33 mcg/unit 3.333 mg/mL | 166.67 mcg/unit 16.667 mg/mL |
| 5 mL | 20 mcg/unit 2 mg/mL | 100 mcg/unit 10 mg/mL |
Each cell shows mcg per unit on a U-100 syringe (100 units = 1 mL) and the resulting concentration.
These volumes are examples, not recommendations. A larger vial may simply need more liquid to dissolve comfortably, and the vial’s capacity limits how much can go in. The broader peptide to BAC water ratio chart explains the same pattern for other sizes.
Worked example: Epithalon 50mg in syringe units
Three steps turn a vial into syringe units. Divide vial mg by water mL to get concentration. Divide the amount you enter by that concentration to get mL. Multiply mL by 100 to get units on a U-100 syringe, where 100 units = 1 mL. For example, if the amount you already have is the figure in this sentence and the vial is Epithalon 50mg:
The math: 50 mg ÷ 5 mL = 10 mg/mL (10,000 mcg/mL), which is 100 mcg per unit. 2 mg ÷ 10,000 mcg/mL = 0.2 mL = 20 units on a U-100 syringe.
The same arithmetic for a 10 mg vial looks like this, again with an arbitrary amount chosen for round numbers:
The math: 10 mg ÷ 2 mL = 5 mg/mL (5,000 mcg/mL), which is 50 mcg per unit. 1 mg ÷ 5,000 mcg/mL = 0.2 mL = 20 units on a U-100 syringe.
Watch the units: 1 mg = 1,000 mcg, and a mix-up between the two is the most common calculator error. The mg to mcg conversion guide is a quick reference.
Epithalon 50mg calculator: what the numbers mean
Searches such as “when to take Epitalon” ask about timing and amounts. This page does not answer those questions. The calculator converts an amount you already have into a volume and a syringe mark; it does not set an amount, a schedule, or a route, and it cannot judge whether any use is appropriate.
What it does is make the arithmetic dependable. With a 50 mg vial the numbers per unit get large, which makes an extra or missing zero easier to overlook. If your result is more liquid than the vial contains, an input is wrong. You can verify any result by hand with the peptide calculator math check.
Epithalon reconstitution notes from suppliers
Epithalon is generally described by suppliers as soluble in water, and most listings specify bacteriostatic or sterile water. Because a 50 mg vial holds a lot of powder, some suppliers state a minimum volume of liquid or note that larger vials take longer to dissolve fully. Where a label or supplier sheet names a diluent, volume, or storage condition, that instruction takes priority over any general page.
Handling and sterility should follow the product labeling and a qualified professional. For general background on the process and the terms used on labels, see how peptide reconstitution works.
Regulatory status of Epithalon
Epithalon is not an FDA-approved drug, and vials sold online are labeled for research use. A research label does not establish identity, purity, sterility, or suitability for use in people, and a correct calculation cannot establish them either. Two products with the same name can differ in content and labeling, so read each label on its own terms.
Epithalon (Epitalon) FAQ
Is Epithalon the same as Epitalon?
Yes. They are two spellings of the same synthetic tetrapeptide, Ala-Glu-Asp-Gly. Both appear on product labels and in search.
How much BAC water goes in an Epithalon 50mg vial?
There is no single correct volume. The chart shows how each volume changes mcg per unit. If the product label names a diluent or volume, follow the label.
Why is the mcg per unit higher for a 50 mg vial?
At the same water volume, a 50 mg vial holds five times as much peptide as a 10 mg vial, so each unit of solution carries five times as many micrograms.
Does this page say when to take Epitalon?
No. It only converts an amount you already have into mL and U-100 syringe units. It does not recommend an amount, timing, or use.
What does AEDG mean?
It is the one-letter code for Epithalon’s four amino acids: alanine, glutamic acid, aspartic acid, and glycine.
