Peptide LibraryIGF-1 LR3 calculator
IGF-1 LR3 is a modified, longer-acting analogue of insulin-like growth factor 1 with no established human dose: no human study of it is indexed and no trial is registered. Mecasermin, the approved recombinant IGF-1, is a different molecule whose dosing does not transfer. Vials are small by peptide standards, 1 mg or 100 mcg, so one syringe mark holds 10 mcg or less; the tables show that arithmetic.

IGF-1 LR3 reconstitution chart
Concentration and micrograms per mark on a U-100 insulin syringe, by vial size and water added. The peptide amount never changes; only how concentrated it is.
| Vial | + 1 mL water | + 2 mL water | + 3 mL water |
|---|---|---|---|
| 0.1 mg | 0.1 mg/mL · 1 mcg per unit | 0.05 mg/mL · 0.5 mcg per unit | 0.03 mg/mL · 0.3 mcg per unit |
| 1 mg | 1 mg/mL · 10 mcg per unit | 0.5 mg/mL · 5 mcg per unit | 0.33 mg/mL · 3.3 mcg per unit |

Why there is no dose table
No human dose of IGF-1 LR3 is established by a published trial, so this page shows concentrations only. The dosage section of the IGF-1 LR3 profile lists what the literature does and does not report, with sources.
Common questions
How much bacteriostatic water do you add to a 1 mg IGF-1 LR3 vial?
There is no single correct volume: the amount of peptide is fixed and the water only sets the concentration. For 1 mg, 1 mL gives 1 mg/mL (10 mcg per unit), 2 mL gives 0.5 mg/mL (5 mcg per unit) and 3 mL gives 0.33 mg/mL (3.3 mcg per unit). More water makes each syringe mark hold less, which makes small amounts easier to measure accurately.
What dose does the IGF-1 LR3 calculator use?
None. No human dose of IGF-1 LR3 is established, so the calculator does not suggest one. It converts a vial size, a water volume and an amount you enter into a volume and syringe units; the tables on this page show concentrations only.
What does one unit on an insulin syringe mean?
A unit is a volume mark, not an amount of drug. On a U-100 syringe 100 units fill 1 mL, so 10 units is always 0.1 mL; how much peptide those 10 units hold depends only on the concentration you mixed. U-40 syringes use 40 marks per mL, so the same volume reads as a different number of units.
