Mechanism of Action

DSIP is an endogenous neuropeptide that crosses the blood-brain barrier and modulates delta-wave sleep, hypothalamic-pituitary-adrenal (HPA) axis output, and stress-hormone regulation in research models. Its precise receptor target remains incompletely defined.

Modulates delta-wave sleep in research models.
🔬
HPA-Axis Modulation
Influences stress-hormone regulation.
🧬
Neuroendocrine Signalling
Broad neuromodulatory activity documented across research groups.

Research Evidence

DATA = directly reported in cited study · INFERENCE = derived · SPECULATION = hypothesis

Graf MV & Kastin AJ (1984) Neurosci Biobehav Rev 8(1)DATA
Reviewed DSIP occurrence, distribution, and neuroendocrine effects in research models (DATA).
Kovalzon VM & Strekalova TV (2006) reviewDATA
Summarised DSIP effects on sleep and stress resistance in research models (DATA).
Mechanistic synthesis · sleep / HPA axisDATA
Sleep and stress-axis modulation is the rationale for research interest; the receptor target is not fully defined (SPECULATION).

Certificate of Analysis

Every Mindtek batch is independently tested before release. We were among the first peptide suppliers in Southeast Asia to implement mandatory third-party HPLC verification — a standard, not an exception.

Research Protocol Reference

For laboratory research use only — not for human or veterinary use.

💧
Reconstitution
Add sterile bacteriostatic water (0.9% benzyl alcohol) slowly against the vial wall. Gently swirl — do not vortex. Allow 5 min for complete dissolution.
🧊
Storage
Store solution-phase at -20°C. Post-reconstitution: maintain at 2–8°C, use within 28 days. Protect from light. Avoid repeated freeze-thaw cycles.
📐
Administration
SubQ or IM administration in standard research protocols. Insulin syringe recommended for precise dosing. Refer to published literature for compound-specific protocols.

Frequently Asked Questions

What is DSIP?
DSIP is a 9-amino-acid neuropeptide (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) an endogenous delta sleep-inducing neuropeptide. Research applications: sleep, stress-axis, and neuroendocrine studies. Research use only.
How is Mindtek DSIP produced?
Synthesised via solid-phase peptide synthesis (SPPS). Each batch: HPLC purity verification (≥99.3%), mass spectrometry identity, endotoxin testing prior to release.
Storage requirements?
Store solution-phase DSIP at -20°C. Post-reconstitution with sterile BAC water: 2–8°C, use within 28 days. Avoid repeated freeze-thaw cycles.
