IGF-1 LR3 0.1 mg vial

How much diluent (its maker uses dilute acetic acid) to add to a 0.1 mg vial of IGF-1 LR3, the syringe units for each common dose, and how many doses the vial holds.

The short answer

Mixed with 1 mL of diluent (its maker uses dilute acetic acid), a 0.1 mg vial of IGF-1 LR3 holds 0.1 mg/mL. A 20 mcg dose is then 20 units (0.20 mL) on a U-100 insulin syringe, and the vial holds about 5 doses of that size. Taken 1× per day, it lasts about 5 days.

Preclinical. No human trials; developed as a cell-culture supplement. The approved IGF-1 drug (mecasermin) is a different molecule.

How much water

The liquid only sets the strength; the dose and the number of doses in the vial stay the same. Draws are on a U-100 insulin syringe, where 1 unit is 0.01 mL.

Draws over 100 units show in mL. Faded values are under 2 units, which is hard to measure. Check that your vial holds the larger volumes.

Where the doses come from

  • Community 20–100 mcg once daily; 20–50 mcg is most often cited.

Doses are what labels, trials or community reports reference, not recommendations. IGF-1 LR3’s page has the cycle, side effects, cautions and sources.

Mixing and storage

  1. PrepareLet a refrigerated vial come to room temperature, and wipe both stoppers with an alcohol swab.
  2. Add 1 mLDraw 1 mL of diluent (its maker uses dilute acetic acid) and let it run slowly down the inside wall of the vial.
  3. Swirl, don’t shakeSwirl gently until the powder dissolves and the liquid is clear.
  4. Label itWrite the date and the strength, 0.1 mg/mL, on the vial.

Storage: Powder: frozen or refrigerated. Mixed: 2–8 °C, use within about 4 weeks.

Questions

How much water do I add to a 0.1 mg vial of IGF-1 LR3?

There’s no single right amount: the liquid only sets the strength. With 1 mL of diluent (its maker uses dilute acetic acid), a 0.1 mg vial holds 0.1 mg/mL. With 2 mL it’s 0.05 mg/mL; with 3 mL it’s 0.0333 mg/mL. Less liquid makes each dose a smaller draw; more makes small doses easier to measure.

How many units is 20 mcg of IGF-1 LR3?

With 1 mL in a 0.1 mg vial, 20 mcg is 20 units (0.20 mL) on a U-100 insulin syringe. With 2 mL, 40 units (0.40 mL); with 3 mL, 60 units (0.60 mL).

How many doses are in a 0.1 mg vial of IGF-1 LR3?

About 5 doses of 20 mcg, or 1 of 75 mcg or 1 of 100 mcg. Taken 1× per day at 20 mcg, it lasts about 5 days.

How long does a mixed vial of IGF-1 LR3 keep?

Powder: frozen or refrigerated. Mixed: 2–8 °C, use within about 4 weeks.
