DSIP
Also known as: DSIP, Delta Sleep-Inducing Peptide
Delta Sleep-Inducing Peptide is a small neuromodulatory nonapeptide studied for its effects on sleep architecture, stress hormones, and pain modulation.
Last updated
Mechanism of Action
DSIP is a nine-amino-acid peptide that crosses the blood-brain barrier and is thought to act as a neuromodulator influencing delta-wave (slow-wave) sleep. It appears to modulate the hypothalamic-pituitary-adrenal axis, lowering circulating corticotropin and cortisol while affecting somatostatin and other neuroendocrine outputs. Research also implicates interactions with opioidergic and GABAergic signaling, contributing to its reported antinociceptive and stress-buffering effects, though its precise receptor target remains undefined.
- Half-life
- Very short; roughly 7-15 minutes in circulation
- Administration Routes
- subcutaneous, intranasal
- Research Status
- Research Chemical
Reported Benefits
- Studied for improving slow-wave sleep quality
- May reduce stress-related cortisol elevation
- Reported antinociceptive (pain-dampening) effects in models
- Investigated for normalizing disrupted circadian rhythm
- May ease symptoms during opioid or alcohol withdrawal in studies
Potential Side Effects
- Headache or grogginess
- Dizziness
- Transient changes in mood or alertness
- Injection-site irritation
Common Dosing
Research literature commonly references subcutaneous doses of about 100-300 mcg before sleep. For research use only; not personal medical advice.
The dosing information above is aggregated from research literature and anecdotal community reports for educational purposes only. It is not a recommendation, prescription, or medical advice. Peptides are sold as research chemicals only and are not intended for human use.
Contraindications
- Known hypersensitivity to the peptide
- Pregnancy or breastfeeding
- Concurrent use of strong sedatives without oversight
Epitalon
A synthetic tetrapeptide (Ala-Glu-Asp-Gly) based on the pineal peptide epithalamin, studied for telomerase activation, circadian regulation, and longevity in animal and limited human research.
N-Acetyl Epitalon Amidate
A modified, more stable form of the tetrapeptide Epitalon studied for telomerase activation and pineal-mediated circadian and longevity effects.
Melatonin
Melatonin is the body's primary circadian hormone, secreted by the pineal gland to signal darkness and regulate sleep timing. It is widely studied as a chronobiotic and antioxidant research compound. Note: Melatonin is a small-molecule hormone, not a peptide, though it appears in some research-compound catalogs.
Pinealon
Pinealon is a synthetic tripeptide (Glu-Asp-Arg) studied in Russian research as a brain-targeted peptide bioregulator with proposed neuroprotective and cognition-supporting effects. It is part of the Khavinson short-peptide bioregulator family.
