Product details
Overview
DSIP (Delta Sleep-Inducing Peptide) is a nonapeptide investigated in neurophysiology. The proposed format contains 10 mg per vial as lyophilized powder. Its name originates from experimental studies of slow-wave EEG activity.
Structure and technical data
Technical data
The reference sequence contains nine amino acids: Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu (WAGGDASGE). The 10 mg format denotes nominal mass per vial rather than a solution concentration.

Research context
Early publications describe isolation, synthesis and EEG evaluation in animal models. They establish the compound’s historical research context, without demonstrating that this commercial material treats insomnia or improves sleep in people.

Origins and experimental context
DSIP was characterized in the 1970s through sleep experiments in rabbits. Early work compared isolated peptide, synthetic material and sequence fragments using electroencephalographic recordings, connecting a defined chemical identity with observable neurophysiological measurements.
What EEG studies measure
Delta activity is a low-frequency component of the EEG signal. Experiments describe recording and behavioural changes in the model studied. Increased delta activity alone is not a measure of sleep quality, and the peptide’s name does not establish a single demonstrated receptor mechanism.
Stability and peptide fragments
Enzymatic degradation is distinct from biological activity. In-vitro studies examined DSIP and analogues in brain extracts. Comparing samples therefore benefits from documenting sequence integrity, possible degradation products and experimental conditions rather than attributing every signal to intact peptide.
Identity and sequence comparison
DSIP should be distinguished from modified analogues and sequence fragments. Analytical planning separates sequence, chemical form and the mass actually measured in a batch.
Batch documentation
Molecular data describe the reference compound. Identity, content and purity of the supplied material must be checked against its batch certificate. This page does not attribute another supplier’s tests or results to this product. For laboratory research only; not for human or veterinary use.
Characterization and synthesis
Isolation of the nonapeptide and EEG comparison with synthetic forms in an animal model.
In-vitro degradation
Study of peptide and analogues in brain extracts, relevant to experimental stability.
What does the mg format mean?
It indicates nominal mass per vial, not an mg/ml concentration or an instruction for use. In the blend, 10+3 mg identifies the two components separately.
Does the structure represent the supplied batch?
The PubChem figure depicts the reference compound. Identity, chemical form, content and purity of actual material require documentation for the corresponding batch.
How are storage and stability checked?
Consult the label, safety data sheet and batch-specific instructions. Molecular properties alone do not establish an expiry date or an after-opening lifetime for this product.
