What is IGF-1 DES used for?
IGF-1 DES is most commonly used for users wanting localized muscle anabolism without LR3-level systemic exposure; site-specific injection users; short anabolism windows. A muscle-growth compound that works more on the local muscle than the whole body. A truncated IGF-1 variant (missing the first 3 amino acids) that acts more locally than IGF-1 LR3, with shorter duration and (in theory) less systemic exposure. Human evidence for IGF-1 DES is limited, so these are the goals people pursue with it, not guaranteed outcomes.
