- Waking up rested
What the studies say so far
Peptide sleep research is at an early stage. Most studies are small, short, or done in animals. Good sleep habits and care for problems like sleep apnea have far more evidence behind them. When you open a study linked on this page, check how many people were in it and how long it ran.

DSIP
Small early studies in peopleObservational study in people · 1 study
Study note. A small, older study (1987) followed 24-hour sleep-wake patterns in people with severe chronic insomnia. It has not been repeated in large modern trials.

MK-677
Small early studies in peopleRandomized trial in people · 1 study
Study note. A small 1997 controlled trial measured sleep quality in young and older men. MK-677 is an oral growth hormone secretagogue, not a peptide.
