IGF-LR3 is the most potent muscle-building peptide I've used. Hypertrophy is noticeable within 2 weeks. Recovery between workouts is dramatically faster. The extended half-life of LR3 makes it superior to regular IGF-1. Handle with respect - this is powerful.
IGF-LR3 delivers on muscle growth. Pump is incredible, recovery is fast. The LR3 variant lasts 20-30 hours which is much better than DES. Need to be careful with blood sugar - can cause hypoglycemia. Not for beginners.
