DSIP

From: $50.00 +

DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring neuropeptide first identified in the 1970s. It has been researched for its roles in sleep regulation, stress response, and endocrine activity. Laboratory studies suggest DSIP may influence circadian rhythms and modulate hormone release. Its broad potential biological effects make it an active subject in neurobiology and peptide research.

Introduction

DSIP (Delta Sleep-Inducing Peptide) is a short-chain neuropeptide originally isolated from the brains of rabbits in 1974. Since its discovery, it has been the focus of research exploring its potential roles in sleep induction, stress modulation, and hormonal regulation. Found naturally in the hypothalamus and other brain regions, DSIP has become a well-known peptide in neuroendocrinology research.


Stability and Bioavailability

In laboratory studies, DSIP has demonstrated both rapid metabolism and a relatively short half-life. Its activity is believed to be mediated through interactions with the central nervous system, particularly regions responsible for circadian rhythm regulation and endocrine balance. Experimental analogs have been explored to enhance stability and extend its research utility.


Research Applications

Sleep and Circadian Rhythm Regulation

Early studies indicated DSIP may influence sleep architecture, particularly by promoting slow-wave sleep. While human trials have produced mixed results, animal studies continue to highlight its possible regulatory role in circadian rhythm and sleep cycles.

Endocrine and Hormonal Modulation

DSIP has been linked to modulation of hormonal secretion in research models. It has been observed to interact with the release of luteinizing hormone (LH), adrenocorticotropic hormone (ACTH), and growth hormone, suggesting potential involvement in neuroendocrine signaling pathways.

Stress and Adaptation Responses

DSIP has also been studied for its possible anti-stress properties. Research indicates it may help regulate responses to environmental or psychological stressors by influencing the hypothalamic-pituitary-adrenal (HPA) axis.


Summary

DSIP is a naturally occurring neuropeptide with documented roles in sleep regulation, hormonal activity, and stress response. Research continues to explore its mechanisms of action and potential implications for circadian biology and neuroendocrinology.

Storage Instructions

All peptides are manufactured using lyophilization (freeze-drying), a process that protects product integrity during shipping and storage. This ensures that peptides remain stable for 3–4 months while in their lyophilized form.

Once reconstituted (mixed with bacteriostatic water), peptides should be stored in the refrigerator and will remain stable for up to 30 days.

Lyophilized peptides (unmixed powder) can be kept at room temperature for short-term storage but should ideally be refrigerated under 4°C (39°F) to maintain stability. For long-term preservation (several months to years), peptides should be stored in a freezer at -20°C to -80°C (-4°F to -112°F).

Proper storage helps maintain purity and quality, ensuring your peptides are reliable for research use.

  • Packed and shipped within 3 business days.
  • Delivers within 2 weeks.
  • Carefully packaged in temperature controlled wrapping.
  • Leak and crack proof.
