IGF-1 LR3
In people
People using LR3 after training describe a strong, full pump, then faster recovery and denser muscle over three to four weeks. Old soft-tissue strains often ease. Blood sugar can dip within an hour of a dose, so people take it near a carbohydrate meal. Some notice hunger, mild headache or water in the hands. Gains hold best when training and protein stay high after the cycle ends.
