DS5 vs Dulaglutide
Side-by-side comparison of key properties, dosing, and research.
Sleep Optimization
DS5GLP-1 / Weight Loss Agonists
Dulaglutide- Summary
- DS5 is a synthetic variant of the delta sleep-inducing peptide (DSIP), a nonapeptide originally isolated from rabbit cerebrospinal fluid during slow-wave sleep. Like DSIP, DS5 is explored for sleep optimization, stress modulation, and circadian rhythm normalization, with proposed improvements in potency or stability over the parent molecule.
- Dulaglutide (brand name Trulicity) is a once-weekly GLP-1 receptor agonist approved by the FDA for type 2 diabetes management and cardiovascular risk reduction. It consists of two GLP-1 analog chains fused to a modified IgG4 Fc fragment, extending its half-life to approximately 5 days. While primarily a diabetes medication, it produces meaningful weight loss and has established cardiovascular outcomes data from the REWIND trial.
