Also known as: IGF1 DES, DES 1-3 IGF-1
IGF-1 DES is a truncated version of Insulin-like Growth Factor 1, a naturally occurring peptide involved in growth and development. It acts by binding to IGF-1 receptors with higher affinity than the full-length IGF-1, enhancing cellular processes such as proliferation and differentiation. Research on IGF-1 DES began with its potential to stimulate muscle growth and repair, given its potent anabolic properties. The peptide's ability to bypass the IGF-binding proteins that typically inhibit IGF-1 activity has made it a subject of interest in studies focusing on tissue regeneration. Today, it is primarily studied for its effects on:
- Muscle growth and repair
- Tissue regeneration
- Cellular differentiation
- Proliferation pathways
