IGF-1 LR3

Growth Hormone & Muscle Arthritis

1mg vial + 1mL BAC water = 2 units = 20mcg — Amounts listed in the Dosify Me data: 20-80mcg — Frequency: daily — Best taken: post-workout

Informational only, not medical advice. Consult a licensed healthcare provider before starting or changing any protocol.

Amounts and schedules here are listed from the Dosify Me compound data (sources below). They are not recommendations: Dosify Me does not tell you what dose to take, so follow your prescriber.

Reconstitution

Every vial size below is mixed to the same concentration, 1 mg/mL, so the syringe reads the same number of units for a given dose no matter which vial you bought.

VialBacteriostatic waterConcentration
0.1 mg0.10 mL1 mg/mL
1 mg1.00 mL1 mg/mL

Dose to syringe units

On a standard 100-unit (1 mL) insulin syringe, at the concentration above:

DoseSyringe units
20 mcg2.0 units
50 mcg5.0 units
80 mcg8.0 units

Amounts listed in the Dosify Me data: 20–80 mcg. Frequency: daily. Timing: post-workout or morning, fasted.

Smallest vial (0.1mg = 100mcg) is a single-use size for some protocols. All vial sizes reconstitute to 1mg/mL (10mcg/unit) so the syringe reads the same regardless of size.

Reading units for IGF-1 LR3

Check one row of the table above: 20 mcg is 0.02 mg; 0.02 mg ÷ 1 mg/mL = 0.02 mL; 0.02 mL × 100 = 2 units.

Side effects

Medication caution

IGF-1 LR3 has insulin-like, blood-sugar-lowering activity; the per-dose duration figures that circulate in community sources are not confirmed by any label or study. Combined with insulin or other diabetes medications, it significantly raises the risk of hypoglycemia — the label for recombinant IGF-1 reports severe lows including seizures. Anyone with diabetes or on blood-sugar-lowering medication should avoid this peptide except under direct medical supervision.

Frequently asked

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

At 1 mg/mL (the concentration every vial size mixes to), 20 mcg of IGF-1 LR3 is 2.0 units on a 100-unit insulin syringe (0.020 mL).

How many units is 50 mcg of IGF-1 LR3?

At 1 mg/mL (the concentration every vial size mixes to), 50 mcg of IGF-1 LR3 is 5.0 units on a 100-unit insulin syringe (0.050 mL).

How many units is 80 mcg of IGF-1 LR3?

At 1 mg/mL (the concentration every vial size mixes to), 80 mcg of IGF-1 LR3 is 8.0 units on a 100-unit insulin syringe (0.080 mL).

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

0.10 mL, which gives 1 mg/mL. Other vial sizes use proportionally more or less water so the syringe reads the same.

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

1.00 mL, which gives 1 mg/mL. Other vial sizes use proportionally more or less water so the syringe reads the same.

How often is IGF-1 LR3 taken?

Daily. Post-workout or morning, fasted Typical cycle: ~4 weeks on, ~4 weeks off; repeat 2–3×/year.
