Neuromodulatorisches 9-AS-Peptid
Aliases: Delta Sleep-Inducing Peptide
DSIP means Delta Sleep-Inducing Peptide, a historical research name for a nonapeptide. The published sequence is Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu.
Each box contains 10 unlabelled vials with 10 mg of DSIP each, 100 mg total per box. Product identification appears only on the outer kit packaging.
The labelled single vial in the product image is illustrative. The selected variant and outer kit packaging determine product identification.
The cited primary paper reports DSIP amino-acid analysis, sequence, and synthesis. It supports molecular identity, not an intended use, dosage, or expected biological outcome. PubMed: Primary source.
Further products for catalog context: Selank. For research use only, not for human or animal use.
Every batch is analyzed by an independent laboratory via HPLC before shipment. We document purity (avg. 99.41% in 2026), mass spectrometry identity, and sterility. Production follows GMP standards in ISO-certified laboratories.
