IGF-1 LR3 (insulin-like growth factor-1 long arginine 3) is a synthetic, modified construct of insulin-like growth factor-1. Because IGF-1 LR3 does not bind to IGF-1 binding proteins very well, it remains active up to 120 times longer than standard IGF-1. IGF-1 LR3 enhances cell division and growth, boosts fat metabolism, and increases muscle repair and hypertrophy by inhibiting myostatin. IGF-1 LR3 promotes tissue repair and maintenance throughout the body, making it a protective molecule against cell damage and the effects of aging.

The recommended dosage for men of IGF-1 LR3 is 40 – 50 mcg each day and 20mcg/day for women. All dosing is subcutaneous or intra muscular injection. You should take your dosage once or twice per day, preferable just before training or after your workout. On non-training days, doses should be with a meal in the morning. IGF-1 LR3 is dosed for 30 days and requires 2 weeks off before starting another cycle. You can expect some of the following with IGF-1LR3;

  • Regulates cellular DNA
  • Helps reverse aging
  • Reduces fat storage in the body
  • Increases pure muscle weight
  • Improves athletic performance
  • Boosts muscle protein synthesis
  • Speeds up metabolism
