Whether you're using Wegovy for weight loss or Ozempic for diabetes, this semaglutide dosage calculator helps ensure accurate dosing.

How does the semaglutide reconstitution calculator work? Enter your vial size (mg), bacteriostatic water volume (ml), target dose (mg), and syringe type. The semaglutide units chart calculator instantly shows your dose in units, concentration, volume per dose, and total doses per vial. The glp 1 reconstitution calculator also provides a complete dosing chart for all standard doses.

How to Calculate Units for Semaglutide

Step 1: Concentration = Vial Size (mg) ÷ Water (ml). Example: 5mg ÷ 2ml = 2.5 mg/ml.

Step 2: Volume = Target Dose (mg) ÷ Concentration (mg/ml). Example: 0.25mg ÷ 2.5 = 0.1 ml.

Step 3: Units = Volume (ml) × Syringe Units per ml. Example: 0.1ml × 100 = 10 units.

How to Reconstitute Semaglutide 5mg Vial

Step 1: Gather supplies — semaglutide vial, bacteriostatic water, alcohol swabs, insulin syringe.

Step 2: Clean vial tops with alcohol swab and let dry completely.

Step 3: Draw 2ml bacteriostatic water into syringe.

Step 4: Inject water slowly down the side of the vial — NEVER directly onto powder.

Step 5: Roll vial gently between palms for 1-2 minutes until solution is completely clear — NEVER SHAKE.

Step 6: Inspect solution — should be clear, colorless, free of particles.

Step 7: Label vial with reconstitution date.

Step 8: Store in refrigerator at 36-46°F (2-8°C) for up to 28 days. Discard after 28 days.

Standard Semaglutide Dosing Protocol

Weeks 1-4: 0.25 mg weekly (10 units for 5mg/2ml).

Weeks 5-8: 0.5 mg weekly (20 units).

Weeks 9-12: 1.0 mg weekly (40 units).

Weeks 13-16: 1.7 mg weekly (68 units).

Week 17 onward: 2.4 mg weekly (96 units).

Important USA Standards

Bacteriostatic Water ONLY: Never use sterile water — bacteriostatic water contains 0.9% benzyl alcohol preservative.

Stability: Reconstituted semaglutide lasts 28 days refrigerated at 36-46°F.

Never Shake: Rolling gently dissolves the peptide; shaking denatures the medication.

Discard: Any unused medication after 28 days, even if solution appears clear.

💡 Expert Tips for Semaglutide Reconstitution

Tip #1: Always use a semaglutide reconstitution calculator before drawing your dose. Never guess your units.

Tip #2: Use bacteriostatic water only — sterile water is NOT safe for multi-dose vials.

Tip #3: Roll gently to dissolve, never shake. Shaking denatures the peptide and reduces potency.

Tip #4: Reconstituted semaglutide lasts 28 days refrigerated. Write the date on the vial when you reconstitute.
