DSIP

Delta sleep-inducing peptide — nonapeptide originally identified in rabbit thalamus. Investigated in neurophysiology research for its putative role in sleep cycle modulation.

Peptides China supplies DSIP as lyophilized powder in sealed vials synthesized at ≥98% purity and verified by HPLC and mass spectrometry. Every batch is tested by the manufacturer for purity and concentration as part of routine quality control. Sourcing is direct — no intermediaries. Free shipping + customs clearance from $500 via specialist courier lanes.

Research Areas

BDNF & Neuroplasticity

Neuropeptide research in this area tracks BDNF expression, synaptic plasticity, and neuroprotective signaling in preclinical cognition and memory-formation models.

Sleep, Stress & Anxiety Models

Experimental protocols examine GABA-ergic modulation, stress-axis response, and sleep architecture in rodent models of anxiety and circadian disruption.

Quality & Testing

Testing methods include HPLC, LC-MS, endotoxins, heavy metals, sterility, water content, visible particulates, assay, impurities, and microbiology panels where applicable. Products are supplied against the specification shown on the applicable product page. The standard catalog purity specification is ≥98% unless otherwise stated. Product-specific specifications and quality-control information may vary by compound and batch. Batch documentation is available on request.
