Retatrutide reconstitution calculator.
Work out the concentration of a reconstituted Retatrutide vial. Presets match the 10 mg / 20 mg formats we stock, and the reference table below is calculated for those exact vials. Research use only.
This tool reports concentration only. It is not dosing guidance, and nothing here is for human use.
Retatrutide concentration reference table
Every combination of the Retatrutide vial sizes we stock and the bacteriostatic water volumes people most often add.
| Vial | BAC water | Concentration | Per 100 µL aliquot |
|---|---|---|---|
| 10 mg | 1 ml | 10 mg/ml | 1 mg (1,000 mcg) |
| 10 mg | 2 ml | 5 mg/ml | 0.5 mg (500 mcg) |
| 10 mg | 3 ml | 3.333 mg/ml | 0.333 mg (333 mcg) |
| 10 mg | 5 ml | 2 mg/ml | 0.2 mg (200 mcg) |
| 20 mg | 1 ml | 20 mg/ml | 2 mg (2,000 mcg) |
| 20 mg | 2 ml | 10 mg/ml | 1 mg (1,000 mcg) |
| 20 mg | 3 ml | 6.667 mg/ml | 0.667 mg (667 mcg) |
| 20 mg | 5 ml | 4 mg/ml | 0.4 mg (400 mcg) |
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 Retatrutide?
An investigational peptide that hits three metabolic receptors at once.
Retatrutide is a synthetic peptide developed by Eli Lilly and still in clinical trials. It is not an approved medicine anywhere. Its distinguishing feature is that a single molecule activates three receptors: GLP-1, GIP and glucagon. Most metabolic peptides hit one or two.
That third arm. Glucagon. Is why it draws so much attention in the research literature. Published trial data made it one of the most-discussed metabolic compounds of recent years, and it is the reason retatrutide is the most requested item in this catalog.

Common questions
What is Retatrutide?
A synthetic investigational peptide that activates the GLP-1, GIP and glucagon receptors simultaneously. It was developed by Eli Lilly and remains in clinical trials, it is not an approved medicine. Listed here as a non-clinical research material only.
How is Retatrutide different from Tirzepatide?
Tirzepatide is a dual agonist: it targets GLP-1 and GIP. Retatrutide adds a third target, the glucagon receptor. That extra arm is the main reason the two are compared in metabolic research.
How much bacteriostatic water do I add to a Retatrutide 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 10 mg / 20 mg.
What concentration does a Retatrutide vial give?
It depends entirely on the solvent volume. The reference table above lists every combination of the 10 mg / 20 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.
