Research Overview
IGF-1 LR3
IGF-1 LR3 has extensive in vitro and animal data. Its role in muscle hyperplasia is well-documented. The extended half-life modification provides practical advantages over native IGF-1.
DSIP
DSIP has moderate clinical evidence from European studies. Human trials show improved sleep quality and normalized sleep-wake cycles. Also studied for alcohol and opiate withdrawal. Unique mechanism distinct from traditional sleep aids.
