Epitalon reconstitution calculator.

Work out the concentration of a reconstituted Epitalon vial. Presets match the 50 mg format we stock, and the reference table below is calculated for those exact vials. Research use only.

How the calculation works

Concentration is the mass of peptide divided by the volume of solvent. A vial holding 5 mg reconstituted with 2 ml of bacteriostatic water gives 2.5 mg/ml, so a 100 µL aliquot contains 0.25 mg. The powder itself adds no meaningful volume at these masses, which is why the water volume alone sets the concentration.

Handling in the Vietnamese climate

Sealed lyophilized vials are stable at room temperature in transit, which is why the material ships dry rather than cold. Once reconstituted, the solution is kept refrigerated and shielded from light. Bacteriostatic water is the usual solvent because the benzyl alcohol in it lets a vial be entered more than once.

What is Epitalon?

A four-amino-acid peptide from Soviet-era pineal gland research.

Epitalon is a synthetic tetrapeptide. Alanine, glutamic acid, aspartic acid, glycine, with a specific history. Soviet researchers worked with an extract of the pineal gland called epithalamin, then identified this four-amino-acid sequence as the fragment they believed carried the activity, and synthesised it directly.

Research attention centres on telomerase and circadian signalling. Worth being straight about: most of the published work comes from a single research lineage and has seen limited independent replication outside Russia.

Common questions

What is Epitalon?

A synthetic four-amino-acid peptide (alanine, glutamic acid, aspartic acid, glycine) identified by Soviet researchers as the active fragment of epithalamin, a pineal gland extract. Listed here as a non-clinical research material.

How strong is the research behind Epitalon?

Limited. Most published work traces back to a single research lineage and has had little independent replication outside Russia. Research interest centres on telomerase and circadian signalling.

How much bacteriostatic water do I add to a Epitalon vial?

There is no single correct volume. The water volume sets the concentration: more water gives a weaker solution and a larger aliquot for the same mass. Common choices are 1 to 5 ml. Enter your vial size above to see what each volume produces for 50 mg.

What concentration does a Epitalon vial give?

It depends entirely on the solvent volume. The reference table above lists every combination of the 50 mg vial format and 1, 2, 3 and 5 ml of bacteriostatic water.

Does the powder change the final volume?

Not measurably at these masses. A few milligrams of lyophilized peptide occupies a negligible volume, so the bacteriostatic water you add is effectively the final volume.

Can I use normal water or saline instead?

Bacteriostatic water is the standard solvent for multi-entry vials because it contains a preservative. Sterile water and saline have no preservative, so they are single-entry solvents.
