About DSIP
DSIP (delta sleep-inducing peptide) is a nonapeptide first characterized in neuroscience research examining delta-wave sleep activity in preclinical models.
Research interest centers on its interaction with neuroendocrine signaling, circadian rhythm modeling, and stress-response pathway investigation in laboratory systems.
This lot is inbound; the listing is published now for reference and will be marked in stock once the shipment arrives and independent testing clears.

Storage & Handling
- Store lyophilized vials at -20°C for long-term laboratory storage; short-term storage at 2–8°C is acceptable for materials in active use.
- Protect vials from light and repeated freeze-thaw cycles; aliquot before freezing where practical.
- Once a vial has been opened in a laboratory setting, use within the timeframe recommended by your institution's SOPs and document handling in your lab notebook.
- Keep sealed vials in a desiccated environment; humidity exposure can degrade lyophilized peptide material over time.
