Reconstitution is the process of dissolving lyophilised (freeze-dried) peptide powder with bacteriostatic water (BAC water) to create an injectable solution. Follow these steps for a safe, sterile process.
You will need your lyophilised peptide vial, a vial of bacteriostatic water, alcohol swabs, and a U-100 insulin syringe. Make sure everything is sealed, sterile and within its use-by date.
Wipe the rubber stoppers of both the peptide vial and the BAC water vial with alcohol swabs. Allow the alcohol to air dry for approximately 10 seconds before proceeding.
Using the calculator above, determine the correct amount of BAC water. Draw that amount into the syringe from the bacteriostatic water vial. Common amounts are 1 mL, 2 mL or 3 mL.
Insert the syringe needle into the peptide vial at an angle. Release the water slowly down the inside wall of the vial. Never spray directly onto the lyophilised powder - this can denature and damage the peptide.
Gently swirl the vial in a circular motion until the powder is completely dissolved. Never shake vigorously. Label the vial with the date, peptide name and concentration, then refrigerate at 2-8 degrees C. Use within 30 days.
Insulin syringes are the standard tool for measuring and administering reconstituted peptides. Here is how the unit markings translate to volume.
100 units = 1 mL. This is the universal standard for U-100 insulin syringes, which are the most commonly used type for subcutaneous peptide research.
Syringe sizes vary. Common sizes are 0.3 mL (30 units), 0.5 mL (50 units) and 1.0 mL (100 units). Choose the smallest syringe that fits your calculated dose for the most accurate measurement.
Needle gauge matters. 31G or 30G needles are recommended for subcutaneous injections. Shorter needles (6 mm or 8 mm) are standard for peptide administration.
Units are NOT milligrams. The unit markings on an insulin syringe measure volume, not weight. The actual mcg of peptide per unit depends on your reconstitution concentration.
Proper storage is essential for maintaining peptide stability and effectiveness. Follow these guidelines to protect your research compounds.
Peptides Pharma research vials come pre-mixed and ready to use. No vials, no bacteriostatic water, no reconstitution needed. Precision dosing in every click.

To reconstitute a peptide vial: (1) Clean the vial stopper with an alcohol swab. (2) Draw bacteriostatic water into a syringe. (3) Inject the water slowly down the inside wall of the vial - never spray directly onto the powder. (4) Gently swirl (do not shake) until the powder is fully dissolved. (5) Store the reconstituted peptide at 2-8 degrees Celsius and use within 30 days.
A standard U-100 insulin syringe has 100 units per 1 mL. So 10 units = 0.1 mL, 25 units = 0.25 mL, 50 units = 0.5 mL, and 100 units = 1.0 mL. This is the most common syringe used for subcutaneous peptide injections.
The amount of bacteriostatic water depends on the peptide amount and your desired concentration. Common choices are 1 mL, 2 mL, or 3 mL. More water means a lower concentration and a larger injection volume per dose, while less water means a higher concentration and smaller injection volume. Use the calculator above to find the optimal volume for your protocol.
1 milligram (mg) equals 1,000 micrograms (mcg). Peptide vials are typically labelled in milligrams (e.g. 5 mg, 10 mg), while individual doses are usually measured in micrograms (e.g. 250 mcg, 500 mcg). Always check whether your dose is in mg or mcg to avoid dosing errors.
Divide the total peptide amount (in mcg) by the total water volume (in mL). For example, a 10 mg vial (10,000 mcg) reconstituted with 2 mL of bacteriostatic water gives a concentration of 5,000 mcg/mL. To find the injection volume for a 250 mcg dose: 250 / 5,000 = 0.05 mL = 5 units on an insulin syringe.
Accurately calculating peptide dosages is one of the most important steps in peptide research. Whether you are working with BPC-157 for tissue repair studies, CJC-1295 and Ipamorelin for growth hormone research, or Tirzepatide for metabolic investigations, getting the reconstitution and dosing right is essential for consistent, reproducible results.
Why reconstitution calculations matter: Lyophilised peptides are shipped as a freeze-dried powder to preserve stability. Before use, they must be reconstituted with bacteriostatic water (BAC water) to create an injectable solution. The amount of water you add directly determines the concentration of the solution, which in turn determines how much liquid you need to draw for each dose.
The core formula is simple: Peptide amount (mcg) divided by water volume (mL) equals concentration (mcg/mL). Then, desired dose (mcg) divided by concentration (mcg/mL) equals injection volume (mL). Multiply the injection volume by 100 to convert to insulin syringe units.
A practical example: You have a 10 mg vial of BPC-157 (10,000 mcg) and add 2 mL of bacteriostatic water. Your concentration is 10,000 / 2 = 5,000 mcg/mL. For a 250 mcg dose, you need 250 / 5,000 = 0.05 mL, which equals 5 units on a standard U-100 insulin syringe.
Peptides Pharma research vials eliminate this complexity entirely. Each vial contains lyophilized peptide with precision click-dosing, so there is no reconstitution, no calculations, and no risk of dosing errors. But for researchers working with traditional vial-and-syringe protocols, this calculator provides the accuracy you need.
Our peptide dosage calculator supports any peptide amount and water volume combination, with common presets for the most popular research protocols. Whether you are in the UK, Europe, or anywhere else, this tool gives you instant, accurate results for your peptide reconstitution calculations.
Peptides Pharma research vials come pre-mixed, precision-dosed and ready to use. No reconstitution required.
