The peptide named after deep sleep itself — Delta Sleep-Inducing Peptide. 10mg research vial.
DSIP (Delta Sleep–Inducing Peptide) is a naturally occurring nonapeptide studied since the 1970s for its role in sleep regulation, stress response, and neuroendocrine function.
What DSIP is
- A nonapeptide (9 amino acids), first isolated in the 1970s
- Found in the brain, pituitary and peripheral tissues
- Named for early research linking it to delta-wave (deep) sleep
Research suggests DSIP may help with
- Sleep modulation — especially deep (delta-wave) sleep phases
- Circadian rhythm regulation
- Stress and cortisol regulation — HPA-axis studies
- Pain perception — nociception research
- Hormonal balance — LH and GH interaction studies
Research areas at a glance
| Research area | What studies explore |
|---|---|
| Sleep architecture | Delta-wave sleep phases and sleep-cycle stability |
| Stress systems | Night-time cortisol patterns and HPA-axis activity |
| Neurotransmitters | GABA, glutamate and serotonin balance |
| Hormones | GH and LH release tied to deep sleep |
How DSIP is studied to work
DSIP doesn't behave like a sedative in research — it appears to act as a regulatory peptide, influencing brain signals tied to sleep, stress and hormones.
1. Brain signaling (sleep regulation)
- Studied for acting in the hypothalamus, which controls sleep cycles
- Researched for promoting delta-wave sleep — the deep, restorative stage
- May stabilize the sleep–wake cycle rather than forcing sedation
👉 Think: fine-tuning sleep quality, not just inducing sleep
2. Stress & cortisol control
- May influence the HPA axis — reducing cortisol spikes, especially at night
- Studied for calming nervous-system activity
3. Neurotransmitter interaction
- GABA → relaxation signaling
- Glutamate → balancing excitatory signals
- Serotonin → mood and sleep-cycle pathways
4. Hormonal effects
- Studied for influence on growth hormone (tied to deep sleep) and LH

Product specifications
| Specification | Detail |
|---|---|
| Vial size | 10mg DSIP |
| Form | Lyophilized (freeze-dried) powder |
| Storage | Cool, dry place away from light; refrigerate after reconstitution |
| Intended use | Laboratory research only — not for human consumption |
Summary
DSIP is studied for:
- Regulating sleep signals in the brain
- Lowering stress/cortisol in studies
- Balancing neurotransmitters
- Supporting deep-sleep cycles
DSIP is NOT a knockout drug — more of a sleep optimizer.
Poor sleep quietly wrecks every other system researchers measure. DSIP is how the field studies fixing it at the signal level.

Reconstitution / BAC Water
Reconstitution / BAC Water
All vial peptides are supplied in lyophilized powder form for research purposes. Reconstitution / BAC Water requires bacteriostatic (BAC) water, and the amount used depends on the concentration required for your research protocol.
Storage & Handling
Storage & Handling
Before reconstitution, keep sealed vials cool, dry, and away from direct light. For longer-term storage, freezing is recommended to preserve stability.
After reconstitution, store refrigerated and use within 30 days for best stability.
