The fusion peptide demonstrated sleep-promoting effects, influenced neurotransmitter levels (5-HT, glutamate, dopamine, melatonin), and confirmed that the Tat cell-penetrating sequence was the more effective BBB carrier of two tested candidates establishing DSIP as a validated active scaffold for BBB-crossing fusion peptide sleep research and supporting the development of next-generation DSIP-based neuromodulatory tools
These companies sell peptides labeled for research purposes only or not for human consumption. Quality varies significantly between suppliers, making vendor selection critical
