IGF-1 LR3 (Insulin-like Growth Factor 1 Long R3) is a modified version of IGF-1 with prolonged half-life and greater anabolic activity. It is widely used experimentally in the bodybuilding community .

Main Expected Effects:
* Increase in protein synthesis and muscle growth .
* Muscle regeneration and accelerated recovery .
* Stimulation of hyperplasia (increase in the number of muscle cells) .
* Improvement in insulin sensitivity (in some cases) .

Risks (Important Cautions):
* Mild to moderate hypoglycemia (main concern) .
* Organ growth if poorly administered .
* Mitogenic potential (stimulates cell division – use with caution) .

Common Protocol (Experimental Use):
* Dose: 20 to 50 mcg per day .
* Route: Subcutaneous or intramuscular (some apply post-workout to the trained muscle) .
* Timing: Post-workout (ideal) or in the morning fasted .
* Duration: 4 to 6 weeks .

Tips:
* Combine with fast carbohydrates after application (prevents hypoglycemia and potentiates action) .
* Must pause after the cycle (continuous use is not recommended).
