IGF-1 LR3 Dosage Calculator: Reconstitution and Units
To calculate an IGF-1 LR3 dose, divide the vial mg by BAC water mL to get concentration (mg/mL), then divide your target dose (mg) by concentration to get draw volume (mL). Multiply mL by 100 for U-100 syringe units. IGF-1 LR3 doses are typically in the 20–100 mcg range.

Common vial and BAC water combinations with calculated concentration, draw volume, and U-100 syringe units. For education only — verify your vial label before use.
| Vial (mg) | BAC water (mL) | Concentration | Dose (mg) | Draw (mL) | U-100 units |
|---|---|---|---|---|---|
| 1 mg | 1 mL | 1 mg/mL | 0.05 mg | 0.05 mL | 5 units |
| 1 mg | 2 mL | 0.5 mg/mL | 0.05 mg | 0.1 mL | 10 units |
| 0.1 mg | 1 mL | 0.1 mg/mL | 0.02 mg | 0.2 mL | 20 units |
| 1 mg | 1 mL | 1 mg/mL | 0.1 mg | 0.1 mL | 10 units |
How to Calculate IGF-1 LR3 Dosage
Three steps convert any vial and BAC water combination into the exact volume to draw on a U-100 insulin syringe.
Step 1 — Calculate concentration (mg/mL)
Divide the total peptide in the vial (mg) by the volume of BAC water you added (mL). For example: a 5 mg IGF-1 LR3 vial reconstituted with 2 mL BAC water gives 5 ÷ 2 = 2.5 mg/mL.Step 2 — Calculate draw volume (mL)
Divide your target dose (mg) by the concentration (mg/mL). For a 0.5 mg dose at 2.5 mg/mL: 0.5 ÷ 2.5 = 0.2 mL. This is the exact volume to draw into the syringe.Step 3 — Convert to U-100 syringe units
Multiply the draw volume (mL) by 100. For 0.2 mL: 0.2 × 100 = 20 U-100 units. Read this number on the unit markings of a standard insulin syringe.
Dosage Formula
Concentration formula
Concentration (mg/mL) = Vial mg ÷ BAC water mLDraw volume formula
Draw volume (mL) = Dose (mg) ÷ Concentration (mg/mL)U-100 syringe units
U-100 units = Draw volume (mL) × 100These three formulas apply to any IGF-1 LR3 vial, regardless of size. U-100 is the standard insulin-syringe scale: 100 units = 1 mL.

Example IGF-1 LR3 Calculations
Step-by-step worked examples using common vial sizes. Results are for illustrating the math only.
1 mg vial + 1 mL BAC + 50 mcg (0.05 mg) dose
- Vial: 1 mg | BAC water: 1 mL | Target dose: 0.05 mg
- Concentration: 1 ÷ 1 = 1 mg/mL
- Draw volume: 0.05 ÷ 1 = 0.05 mL
- U-100 units: 0.05 × 100 = 5 units
1 mg vial + 2 mL BAC + 100 mcg (0.1 mg) dose
- Vial: 1 mg | BAC water: 2 mL | Target dose: 0.1 mg
- Concentration: 1 ÷ 2 = 0.5 mg/mL
- Draw volume: 0.1 ÷ 0.5 = 0.2 mL
- U-100 units: 0.2 × 100 = 20 units
IGF-1 LR3 Reconstitution Guide
IGF-1 LR3 is supplied as a lyophilized powder, usually in 0.1 mg or 1 mg vials.
- Add BAC water slowly along the vial wall. Do not shake — gently swirl until dissolved.
- Common setup: 1 mg vial + 1 mL BAC = 1 mg/mL. Each 0.05 mg (50 mcg) dose = 0.05 mL = 5 units.
- Refrigerate at 2–8 °C and use within 3–4 weeks once reconstituted.
Frequently Asked Questions
What is IGF-1 LR3?
IGF-1 LR3 is a modified form of insulin-like growth factor-1 with an extended half-life. It is studied in muscle growth and recovery research contexts. This calculator only converts mg to mL and syringe units.
How do I convert IGF-1 LR3 mcg to mg?
Divide mcg by 1000. For example: 20 mcg = 0.02 mg, 50 mcg = 0.05 mg, 100 mcg = 0.1 mg. Enter the mg value in the calculator.
What are U-100 syringe units?
U-100 is the standard scale for insulin syringes. 100 units = 1.0 mL. That means 10 units = 0.1 mL, 50 units = 0.5 mL. Multiply any draw volume in mL by 100 to get the U-100 units reading.
Do I need to recalculate if I change the amount of BAC water?
Yes. Changing BAC water volume changes the concentration (mg/mL), which changes the draw volume for the same mg dose. Always recalculate using: concentration = vial mg ÷ BAC water mL, then draw volume = dose mg ÷ concentration.
How do I convert mcg to mg for the calculator?
Divide mcg by 1000 to get mg. For example: 250 mcg = 0.25 mg, 500 mcg = 0.5 mg, 1000 mcg = 1 mg. Enter the mg value in the calculator.
