Product Summary:

IGF-1 LR3 is the next generation in performance enhancement for muscle building. It is the most important growth factor that our bodies produce, even more so than HGH.

IGF1-LR3 Insulin Growth factor Long LR3. IGF-1 is a polypeptide hormone that has some of the same properties as insulin.

Responsible for long bone growth in children, IGF-1 has anabolic effects on the muscle growth, repair and recovery of adults.

Key Benefits:

  • Increased muscle cells
  • Enhanced pumps
  • Bigger reps
  • Increased strength
  • Phenominal increased lifts
  • Faster recovery times


IGF-1 is sold in vials containing 1MG of lyophilised powder which should be stored under refrigeration.

(It is acceptable however for them to be mailed unrefrigerated). The contents can be reconstituted by adding a convenient amount of sterile or bacteriostatic water.

For example:

1mg of powder

1ml of bacteriostatic water

equals 1,000 mcg/ml

equals x 10 doses of 100mcgs

IGF-1 LR3 can be taken up to 7 days a week at a dose of 50 – 150mcg a day. Desensitization has been shown to occur at around 40 days or roughly 4 weeks.

At time of dosing, an insulin syringe is used to draw and then inject the desired amount. In the above example, a 100 mcg dose would require only 0.10 mL, or “10 IU” as marked on an insulin syringe.
