IGF-1 LR3 reconstitution calculator
Solution arithmetic for lyophilized IGF-1 LR3: concentration from vial mass and solvent volume, the solvent volume for a target concentration, and aliquot volumes. The molecular weight (9117.5 Da) is filled in so results also show millimolar values. You enter every amount; nothing is suggested.

Formulas
- Concentration: mg/mL = mass (mg) ÷ volume (mL). µg/mL = mg/mL × 1000.
- Solvent volume: volume (mL) = mass (mg) ÷ target concentration (mg/mL).
- Aliquot volume: volume (mL) = mass wanted (mg) ÷ solution concentration (mg/mL). µL = mL × 1000.
- Molar: mM = mg/mL ÷ molecular weight (g/mol) × 1000.
- Units: 1 mg = 1000 µg. 1 mL = 1000 µL.
Worked arithmetic for IGF-1 LR3
Each cell is simply mass ÷ volume, with the molar value from the listed molecular weight (9117.5 Da). Rows use round example masses. The table illustrates the formula; it is not a recommendation for any amount or volume.
| Vial mass | 1 mL solvent | 2 mL solvent | 3 mL solvent | 5 mL solvent |
|---|---|---|---|---|
| 5 mg | 5 mg/mL 5,000 µg/mL · 0.548 mM | 2.5 mg/mL 2,500 µg/mL · 0.274 mM | 1.67 mg/mL 1,670 µg/mL · 0.183 mM | 1 mg/mL 1,000 µg/mL · 0.11 mM |
| 10 mg | 10 mg/mL 10,000 µg/mL · 1.1 mM | 5 mg/mL 5,000 µg/mL · 0.548 mM | 3.33 mg/mL 3,330 µg/mL · 0.366 mM | 2 mg/mL 2,000 µg/mL · 0.219 mM |
Formulas used
- Concentration: mg/mL = vial mass (mg) ÷ solvent volume (mL).
- Molar: mM = mg/mL ÷ 9,117.5 g/mol × 1000.
- Aliquot volume: µL = mass wanted (µg) ÷ concentration (µg/mL) × 1000.
Stated vial mass is gross lyophilized powder. Net peptide content can be lower because of counter-ions and water; the purity and net peptide content calculator corrects a nominal concentration if you have those values.

IGF-1 LR3 calculator FAQ
How is IGF-1 LR3 concentration calculated after reconstitution?
Divide the vial mass by the solvent volume. For example, 5 mg in 2 mL gives 2.5 mg/mL (2,500 µg/mL). This is unit arithmetic only, not a recommendation for any amount.
How do I convert IGF-1 LR3 mg/mL to millimolar?
Divide mg/mL by the molecular weight (9117.5 Da) and multiply by 1000. 2.5 mg/mL ÷ 9,117.5 g/mol × 1000 = 0.274 mM.
Why can the real concentration be lower than the calculated value?
The stated vial mass is gross lyophilized powder. Counter-ions (such as acetate or TFA) and residual water mean net peptide content is lower than gross mass, so the true peptide concentration can be lower. The purity and net peptide content calculator applies that correction if you have the values.
