DSIP
SleepCircadian
Delta sleep-inducing peptide is a naturally occurring neuropeptide investigated for possible relationships with sleep regulation, stress response, and circadian biology.
What does it do?
- Studied for deeper, more restorative delta-wave sleep
- May help reset disrupted circadian rhythms
How does it work?
- Modulates delta-wave sleep and circadian rhythm signaling
- Interacts with stress-response and neuroendocrine systems
How it's typically administered
- Subcutaneous injectionmost common route in research
- Nasal sprayused occasionally; limited absorption data
- Topical serum or creamnot effective systemically
- Oral capsulesnot bioavailable orally
- Intramuscular injectionunnecessary and higher risk
How it's typically dosed
- Most common dose100–300 mcg
- Frequency5 nights on / 2 off
- Cycle duration2–4 weeks
