DSIP

Intended Use:
DSIP is intended for research purposes only. It is commonly studied in models involving sleep regulation, stress response, and neurological balance.

Storage:
Store in a cool, dry place away from direct light. After reconstitution, refrigerate at 2–8°C.

Solubility:
Reconstitute with bacteriostatic water (BAC water) for optimal stability.

Vial Size:
Standard 3ml vial (can hold up to 3ml BAC water).

Shelf Life:

  • Lyophilized: Stable up to 24 months
  • Reconstituted: Recommended use within 4–6 weeks

 

Handling:
Use sterile techniques during preparation and handling.

Sleep Regulation Studies
DSIP has been investigated for its role in promoting delta wave sleep, which is associated with deep, restorative sleep phases.

Stress & Cortisol Modulation
Research suggests DSIP may influence stress-related hormones such as cortisol, potentially helping regulate stress responses.

Neuroendocrine Balance
Studies indicate DSIP may interact with the hypothalamic-pituitary axis, affecting hormonal signaling and balance.

 

Pain & Recovery Research
Some experimental models show DSIP may have effects on pain perception and recovery, especially under stress-related conditions.

DSIP is believed to act on the central nervous system, particularly in regions responsible for sleep and hormonal regulation.

Its proposed actions include:

  • Modulating delta brain wave activity (deep sleep phase)
  • Regulating stress hormone release (such as cortisol)
  • Supporting neurotransmitter balance
  • Influencing the hypothalamic-pituitary axis
  • BAC Water Sold Separately
  • Syringes Not Included
  • Peptides sold in powdered form

DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring neuropeptide originally identified for its potential role in sleep regulation. It is widely studied in research related to circadian rhythm, stress response, and neuroendocrine balance. DSIP is often explored for its calming and regulatory effects on the central nervous system.

Why is my tracking not updating?
Tracking information may take 1–3 days to activate after shipment.
This is normal — once it updates, you’ll be able to see the full tracking progress.
How should peptides be stored?
Lyophilized (powder) peptides can be stored at room temperature before mixing.
After reconstitution, they should be refrigerated (2–8°C) and used within 4–6 weeks.
Unmixed (lyophilized) peptides can remain stable for up to 24 months when stored properly.
