U-100 / U-50 / U-30Semaglutide 5mg (in 2.0 mL BAC Water) Standard Titration Chart
With 5 mg dissolved in 2.0 mL bacteriostatic water, the concentration is exactly 2.5 mg/mL (25 mcg per 0.01 mL / 1 unit on a U-100 syringe).
| Titration Phase | Target Dose | Volume (mL) | U-100 Draw | Clinical Notes |
|---|---|---|---|---|
| Weeks 1–4 (Initiation) | 0.25 mg (250 mcg) | 0.10 mL | 10 Units | Initial starting dose to assess gastrointestinal tolerability. |
| Weeks 5–8 (Escalation) | 0.50 mg (500 mcg) | 0.20 mL | 20 Units | First escalation step; typical initial maintenance dosage. |
| Weeks 9–12 (Target) | 1.00 mg (1,000 mcg) | 0.40 mL | 40 Units | Established clinical therapeutic dose for glycemic control & satiety. |
| Weeks 13–16 (High-Tier) | 1.70 mg (1,700 mcg) | 0.68 mL | 68 Units | Advanced titration level (a 10mg vial is often preferred to reduce draw volume). |
| Weeks 17+ (Maximum) | 2.40 mg (2,400 mcg) | 0.96 mL | 96 Units | Maximum clinical dose (approaches full 1.0 mL barrel capacity on U-100). |

| Target Dose | Volume (mL) | U-100 Units | U-50 Units (0.5mL) | U-30 Units (0.3mL) | Measurement Precision |
|---|---|---|---|---|---|

| 100 mcg | 0.040 mL | 4 Units | 4 | 4 | Small draw; U-30 recommended |
| 250 mcg | 0.100 mL | 10 Units | 10 | 10 | High precision |
| 500 mcg | 0.200 mL | 20 Units | 20 | 20 | High precision |
| 1.0 mg (1,000 mcg) | 0.400 mL | 40 Units | 40 | Exceeds 0.3mL | High precision |
| 2.0 mg (2,000 mcg) | 0.800 mL | 80 Units | Exceeds 0.5mL | Exceeds 0.3mL | High precision |
| 2.5 mg (2,500 mcg) | 1.000 mL | 100 Units | Exceeds 0.5mL | Exceeds 0.3mL | High precision |
| 5.0 mg (5,000 mcg) | 2.000 mL | 200 Units (>1.0mL) | Exceeds 0.5mL | Exceeds 0.3mL | Exceeds syringe capacity |
| 10.0 mg (10,000 mcg) | 4.000 mL | 400 Units (>1.0mL) | Exceeds 0.5mL | Exceeds 0.3mL | Exceeds syringe capacity |
A common point of confusion is searching for an "IU peptide calculator". On an insulin syringe, the tick marks indicate volumetric syringe units (where 100 units = exactly 1.0 mL, meaning 1 mark = 0.01 mL). These are not biological International Units (IU). Peptides (Semaglutide, Tirzepatide, BPC-157) are measured in metric mass (milligrams and micrograms), not IU. Use this matrix to convert your prescribed mass (mcg or mg) into exact volumetric syringe units.
Stoichiometric Principles & Meniscus Precision
- Concentration Stoichiometry: 5 mg powder + 2.0 mL BAC water = 2.5 mg/mL (2,500 mcg/mL).
- Single Unit Potency: Each 1 unit on a U-100 syringe equals exactly 25 mcg (0.025 mg) of active Semaglutide.
- Total Starter Doses: A single 5 mg vial yields twenty (20) 0.25 mg doses or ten (10) 0.50 mg doses.
- Precision Recommendation: For 0.25 mg (10 units) doses, a U-30 or U-50 syringe provides significantly wider tick spacing, minimizing meniscus parallax reading errors.
Critical Errors to Avoid
Semaglutide 5mg Reconstitution Calculator Questions Answered
How much bacteriostatic water should I add to a 5mg Semaglutide vial?
The standard, most practical dilution is 2.0 mL of bacteriostatic water. This yields a clean concentration of 2.5 mg/mL, making a 0.25 mg starting dose exactly 10 units (0.10 mL) and a 0.50 mg dose exactly 20 units (0.20 mL) on a standard U-100 insulin syringe.
How many units is a 0.25 mg dose from a 5mg vial?
If reconstituted with 2.0 mL BAC water, 0.25 mg is exactly 10 units on a standard U-100 insulin syringe. If you reconstituted with 1.0 mL BAC water instead, 0.25 mg would be 5 units.
How many units is a 0.5 mg dose of Semaglutide?
When reconstituted with 2.0 mL BAC water, a 0.50 mg dose is exactly 20 units on a U-100 insulin syringe.
Why should I never shake the vial after adding water?
Semaglutide is a 31-amino acid peptide chain with a synthetic C-18 fatty diacid chain. Vigorous shaking causes severe interfacial mechanical shear, causing the peptide to denature (unfold) and form inactive protein clumps. Always roll the vial gently between your palms.
