Sleep is where peptide claims outrun peptide evidence by the widest margin. Only one compound on the site targets sleep directly, and its human data is old and small. The others help sleep as a side effect of what they actually do, which is worth knowing before you buy anything specifically for sleep.

The only direct sleep peptide. Delta sleep-inducing peptide, discovered in the 1970s, modest human trials, mixed results. Works for some people, does nothing for others.

Not a sleep peptide, but the anxiolytic effect helps people whose problem is a racing mind at bedtime.

Regulates melatonin rhythm in animal studies. Usually run as a short course and reported to deepen sleep during and after.
Dosage5 to 10 mgFrequencyonce dailyRouteSubcutaneous, Intramuscular, Intranasal, Oral - 4Full guideIpamorelinWell researched
A nightly GH pulse before bed. Many users report deeper sleep as the first noticeable effect, which fits the biology of slow-wave sleep and GH release.
Dosage100 to 300 mcgFrequency1 to 3 times dailyRouteSubcutaneous
If sleep is the goal and nothing else, try DSIP first and give it two weeks. If anxiety is the real problem, Selank. If you were already considering a GH secretagogue for other reasons, ipamorelin at night covers both. Fix light, caffeine, and schedule before spending money on any of these.

Best peptides for sleep: frequently asked
What is the best peptide for sleep?
DSIP is the only one designed for it, and its human data is old, small and mixed. It works for some people and does nothing for others, commonly reported at 100 to 300 mcg before bed. If a racing mind is the problem, Selank; if you were already considering a GH secretagogue, ipamorelin at night covers both.
Does ipamorelin help you sleep?
Many users report deeper sleep within 1 to 2 weeks as the first noticeable effect, which fits the link between slow wave sleep and GH release. There is no sleep trial of ipamorelin; the reports are community experience. It is dosed before bed on an empty stomach, commonly 100 to 300 mcg.
Is DSIP safe?
The small 1980s human studies reported no serious effects, which is limited reassurance. Common complaints are headache, next morning grogginess, vivid dreams, and in some people feeling more wired rather than sleepy. It degrades quickly once reconstituted, so old solution may be inactive.
Which peptide helps with anxiety at bedtime?
Selank. It is a Russian prescription anxiolytic with small trials against benzodiazepines, and it calms without sedation, so it suits people whose insomnia is driven by overthinking. Some pair daytime Selank with evening DSIP. See Semax vs Selank for how it differs from its activating cousin.
Can you take DSIP and ipamorelin together?
Yes, and some people do, on the theory that DSIP supports deep sleep when GH release peaks. There is no combined data. Both are injected before bed; ipamorelin needs an empty stomach to work, DSIP does not care.
