Delta Sleep-Inducing Peptide (DSIP)
 

Primary Functions

1. Sleep Regulation:
   DSIP is most well-known for its ability to influence sleep patterns, particularly slow-wave sleep (deep, restorative sleep). It does not appear to act like conventional sedatives; instead, it seems to modulate the body’s natural sleep-wake cycles by affecting neurotransmitter systems and possibly the hypothalamic-pituitary-adrenal (HPA) axis.
    

2. Stress Modulation:
   DSIP may help regulate the stress response by influencing cortisol levels. Some studies suggest it can reduce elevated cortisol, potentially contributing to relaxation and improved sleep quality in individuals experiencing stress-related sleep disturbances.
    

3. Pain and Analgesic Effects:
   Research indicates DSIP might have mild analgesic (pain-relieving) properties. It seems to interact with the body’s pain pathways, possibly by influencing endorphin release, though evidence is limited.
    

4. Endocrine Influence:
   DSIP has been linked to modulation of the endocrine system. There is some evidence that it can influence growth hormone release and possibly interact with the reproductive hormone axis, though these effects are less understood and inconsistent across studies.
    

5. Neuroprotective and Mood Effects:
   Preliminary animal studies suggest DSIP may have neuroprotective properties and could influence mood and anxiety, but human data are sparse.
    

Mechanism of Action:

DSIP’s exact mechanism is not fully understood. It appears to interact with multiple neurotransmitter systems, including GABA, serotonin, and melatonin pathways, which play key roles in sleep regulation. It may also affect the HPA axis, balancing stress hormones and stabilizing sleep patterns.
 

Administration and Research:

DSIP is typically studied in research settings, often administered intravenously or via intranasal routes in animals. Oral bioavailability is very low due to peptide degradation in the digestive tract. There is limited clinical data in humans, so usage is largely experimental or investigational.
 

Potential Uses:

• Improving sleep quality, particularly deep slow-wave sleep

• Reducing stress-induced sleep disturbances

• Supporting mild pain management or mood regulation (experimental)
   

Safety and Considerations:

• DSIP is generally considered low in toxicity in research models

• Effects in humans are not well-documented

• Long-term safety and optimal dosing are not established
   

DSIP is a sleep-modulating peptide with additional potential roles in stress regulation, pain modulation, and neuroprotection. Its research is still early, particularly in humans, but it remains a peptide of interest for sleep disorders and related conditions.

​

Delta Sleep-Inducing Peptide (DSIP) dosing is not well-established because human clinical research is very limited. Most dosing information comes from animal studies or anecdotal biohacker reports. 
 

Typical Experimental Dosing:(Human/Research Context)

• Intravenous (IV) or Subcutaneous (SC) Injection:
  Studies in humans and anecdotal reports suggest doses around 100–300 micrograms per day. Some protocols split the dose into multiple smaller injections.

• Timing:
  Because DSIP primarily affects slow-wave sleep, it’s usually administered 30–60 minutes before bedtime.
   

Other Considerations:

• Oral administration is ineffective, as the peptide is broken down in the digestive system.

• Short half-life: DSIP has a short half-life in the bloodstream, often only 10–15 minutes, so timing relative to sleep is important.

• Stacking: Some biohackers combine DSIP with melatonin, GABA, or other sleep-promoting peptides to enhance deep sleep effects, though this is experimental.
   

Safety Notes:

• Human data are sparse; start at the lower end of reported doses if experimenting in a research context.

• Long-term safety is unknown.

• Avoid concurrent use with sedatives unless under clinical supervision.

 

DSIP Sleep Stack Protocol:

1. Core Peptide: DSIP

• Dose: 100–200 mcg

• Route: Subcutaneous (SC) injection is preferred; intravenous (IV) is also used in research settings

• Timing: 30–60 minutes before bedtime

• Frequency: Once daily, typically in the evening

• Notes: Start at the lower end (100 mcg) to gauge response. DSIP has a short half-life (~10–15 minutes), so timing relative to sleep onset is critical.

 

2. Sleep Synergy Compounds:

Melatonin

• Dose: 0.5–3 mg

• Timing: 30–60 minutes before bedtime

• Purpose: Enhances sleep onset; can complement DSIP’s effect on deep sleep

GABA (Gamma-Aminobutyric Acid)

• Dose: 250–500 mg

• Timing: 30 minutes before bed

• Purpose: Supports relaxation and slows nervous system activity; may enhance DSIP’s sleep-promoting effects

Magnesium (Glycinate or Threonate)

• Dose: 200–400 mg

• Timing: Evening with food or 30 minutes before bed

• Purpose: Supports muscle relaxation, nervous system calm, and sleep quality

 

 Optional Stack Enhancers:

5-HTP (Serotonin Precursor)

• Dose: 50–100 mg

• Timing: 30–60 minutes before bed

• Purpose: Supports serotonin and melatonin production; may improve sleep depth
   

Cognitive/Recovery Support:

• Some biohackers add MOTS-C or GH secretagogues earlier in the evening to support recovery and hormonal balance, though these are optional and highly experimental

 

4. Suggested Protocol Example:

1. 7:00–8:00 PM – Light dinner, avoid caffeine

2. 9:30 PM – Take magnesium + optional 5-HTP

3. 10:00 PM – Subcutaneous DSIP injection + melatonin + GABA

4. 10:30–11:00 PM – Lights out; ensure dark, quiet environment

 

5. Safety Notes:

• Monitor for excessive drowsiness or unusual reactions

• Avoid combining with prescription sedatives without medical guidance

• Long-term human safety data are limited; use the lowest effective dose
   

Delta Sleep-Inducing Peptide (DSIP) is a naturally occurring neuropeptide that was first discovered in the 1970s in the brains of rabbits. It is a short peptide consisting of nine amino acids (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) and is primarily associated with regulating sleep, though research has suggested it may have additional physiological effects. Here’s a detailed breakdown:
