IGF-1 LR3 calculator

IGF-1 LR3 reconstitution & dosage calculator

Pre-loaded with the IGF-1 LR3 defaults from the literature. Adjust vial size, diluent, target dose, and syringe to fit your protocol. Supports mg, mcg, and IU.

Common research range for IGF-1 LR3: 20–100 mcg, 1× daily, subcutaneous. Cycle: 4 weeks on / 4 off.

About IGF-1 LR3

A long-acting analogue of IGF-1 with 83 amino acids, studied for tissue growth, muscle protein synthesis, and cellular recovery.

Research dose ranges

  • Dose: 20–100 mcg per administration
  • Frequency: 1× per day
  • Route: subcutaneous
  • Half-life: ~25 hours
  • Cycle: 4 weeks on / 4 off

Research protocols report doses of 20–100 mcg subcutaneously or intramuscularly once daily, typically post-exercise in muscle-focused studies. Short cycles (4 weeks on, 4 weeks off) are common due to concerns about receptor desensitization.

Storage

Store lyophilized vials at -20°C for long-term stability; short-term storage at 2–8°C is acceptable. Reconstituted solution should be refrigerated and used within 14–21 days.

IGF-1 LR3 calculator FAQ

How do I use the IGF-1 LR3 calculator?+

Confirm your vial size in mg (default 1), set the diluent volume in mL (default 2), enter your target dose, and the calculator returns the concentration, the exact insulin-syringe units to draw, and how many doses your vial yields.

What's the standard IGF-1 LR3 reconstitution?+

Most IGF-1 LR3 research protocols reconstitute a 1 mg vial with 2 mL of bacteriostatic water, yielding 500 mcg/mL.

What syringe should I use for IGF-1 LR3?+

U-100 insulin syringes are standard for IGF-1 LR3 subcutaneous administration. 0.5 mL barrels have clearer unit markings for typical research doses.

Does the IGF-1 LR3 calculator support mg and IU?+

Yes. Enter your dose in mcg, mg, or IU. For IU, set the mcg-per-IU ratio (333 for HGH is a common default).
