Semaglutide reconstitution calculator.
Work out the concentration of a reconstituted Semaglutide vial. Presets match the 5 mg format 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.
Semaglutide concentration reference table
Every combination of the Semaglutide vial sizes we stock and the bacteriostatic water volumes people most often add.
| Vial | BAC water | Concentration | Per 100 µL aliquot |
|---|---|---|---|
| 5 mg | 1 ml | 5 mg/ml | 0.5 mg (500 mcg) |
| 5 mg | 2 ml | 2.5 mg/ml | 0.25 mg (250 mcg) |
| 5 mg | 3 ml | 1.667 mg/ml | 0.167 mg (167 mcg) |
| 5 mg | 5 ml | 1 mg/ml | 0.1 mg (100 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 Semaglutide?
The GLP-1 agonist that started the modern metabolic peptide wave.
Semaglutide is a 31-amino-acid peptide built on the natural GLP-1 hormone, with a fatty-acid chain attached that stops the body clearing it within minutes. That single engineering change turned a hormone with a two-minute half-life into one that persists for about a week.
It is an approved medicine in many countries under the brand names Ozempic, Wegovy and Rybelsus, and it has the deepest published trial record of anything in this catalog. It is listed here as a research material, not as a branded pharmacy product.

Common questions
What is Semaglutide?
A 31-amino-acid peptide analog of the natural GLP-1 hormone, modified with a fatty-acid chain so it lasts around a week instead of minutes. It is approved as a medicine in several countries under names including Ozempic and Wegovy. Listed here as a non-clinical research material only.
Is Semaglutide the same as Ozempic?
Semaglutide is the molecule; Ozempic, Wegovy and Rybelsus are brand names of approved medicines built on it. This catalog lists the research material, not a branded pharmacy product.
How much bacteriostatic water do I add to a Semaglutide 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 5 mg.
What concentration does a Semaglutide vial give?
It depends entirely on the solvent volume. The reference table above lists every combination of the 5 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.
