Why does the vial look empty?

That’s normal. The peptide is supplied lyophilised (freeze-dried) — often a thin film or a few milligrams at the base of the vial, easy to mistake for empty. It’s all there; reconstitute with bacteriostatic water before use.

Research handling note

Reconstitute with bacteriostatic water and store the lyophilised vial at −20 °C until use; once reconstituted, refrigerate and use within the documented window.

Neuropeptide Research

DSIP — research profile

For research purposes only — not for human consumption

DSIP (Delta Sleep-Inducing Peptide) is a nonapeptide — a nine-amino-acid neuropeptide — first isolated from the cerebral venous blood of animals during induced sleep. It is studied for its association with delta-wave (slow-wave) sleep and for a range of neuroendocrine effects.

Research reports involvement in sleep architecture, modulation of the stress-response and hypothalamic–pituitary–adrenal (HPA) axis, and interaction with several neurotransmitter and hormone systems — though its exact mechanism remains an active research question.

How it’s studied

Sleep architecture: delta/slow-wave sleep patterns in EEG models.
Stress response: modulation of the HPA axis and stress hormones.
Neuroendocrine signalling: interaction with hormone and neurotransmitter systems.
Thermoregulation: reported effects in temperature-regulation models.

Areas under investigation

Area	Reported research focus
Sleep regulation	Slow-wave sleep and circadian models.
Stress & HPA axis	Neuroendocrine stress-response pathways.
Neuroprotection	Oxidative-stress and neuromodulation studies.

Verifiability

Batch Testing & COA

Every production batch is sent for independent, third-party analysis at Janoshik Analytical. When results return, the full Certificate of Analysis for the exact batch you receive is published here and in our COA library, carrying its SHA-256 checksum and the lot number printed on your vial, so you can confirm the document is genuine and untampered. We publish every certificate, including any that fail.
