IGF-1 DES (Insulin-like Growth Factor 1 DES) is a truncated form of IGF-1 that has been modified for increased potency. It plays a crucial role in promoting muscle growth, tissue repair, and overall cellular regeneration. IGF-1 DES is known for its enhanced ability to stimulate muscle cell proliferation and enhance recovery, making it popular in research related to muscle hypertrophy and regeneration. It works by mimicking the effects of growth hormone, promoting anabolic processes in the body.
