IGF-1 LR3dosage & bacteriostatic water calculator — stock concentration and syringe units.
IGF-1 LR3 is an 83-amino-acid analog of insulin-like growth factor 1 with an extended activity profile from an arginine substitution at position 3. It ships lyophilized in a 1 mg vial and is reconstituted with bacteriostatic water. This calculator presets IGF-1 LR3 so you can convert its vial and a water volume into an exact stock concentration and syringe draw.

At 0.5 mg/mL, draw 0.5 mL to measure 250 mcg.
Molecular weight is informational; the reconstitution math depends only on the mass in the vial and the water you add.
Reconstitute a 1 mg IGF-1 LR3 vial with 2 mL of bacteriostatic water:

500
mcg/mL
To measure 250 mcg at that concentration you would draw 50 units (0.5 mL) on a U-100 insulin syringe. Change the vial size, water, or target in the calculator above for your own numbers.
Stock concentration (mg/mL) for IGF-1 LR3's vial size at common bacteriostatic-water volumes.
| Vial | 1 mL | 2 mL | 3 mL |
|---|---|---|---|
| 1 mg | 1 mg/mL | 0.5 mg/mL | 0.33 mg/mL |
Multiply mg/mL by 1,000 for mcg/mL. On a U-100 syringe, 1 mL = 100 units.
The volume sets the concentration: 1 mg in 1 mL is 1 mg/mL (1,000 mcg/mL); 1 mg in 2 mL is 0.5 mg/mL. Because the vial is only 1 mg, small water volumes are common — enter your numbers above.
Divide the target in mcg by the concentration in mcg/mL for the volume, then multiply by 100 for U-100 units. With a 1 mg vial the concentration is low, so the calculator helps you pick a water volume that keeps the draw readable.
Refrigerated at 2–8 °C, protected from light, in single-use aliquots — larger proteins are especially sensitive to repeated freeze-thaw. Laboratory storage guidance only.
IGF-1 LR3 is studied in preclinical, in-vitro research on IGF-receptor binding kinetics and downstream growth-signaling pathways. For laboratory research use only.
