About DSIP
DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring neuropeptide first identified in the 1970s for its role in promoting slow-wave (deep) sleep. It consists of a short chain of amino acids that may act on the hypothalamus and pituitary gland, thereby influencing how the body handles sleep, recovery and hormonal stress responses.

Important questions answered by professionals
*Answered by independent medical researchers and licensed physicians
What is DSIP as a research peptide?
DSIP (Delta Sleep-Inducing Peptide) is a nonapeptide with the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu, first isolated in 1974 from the cerebral blood of rabbits in an induced sleep state. It is studied in laboratory and in vitro research for its role in sleep- and stress-related processes. DSIP is sold by MyPeptidesLab strictly for in vitro research and is not approved by the EMA, FDA or any national medicines authority.
What is DSIP being researched for?
In preclinical and in vitro studies, DSIP is being researched in relation to sleep regulation, stress resilience and pain perception, and additionally to possible antioxidant and immunomodulatory properties. Research findings are preliminary and require further validation.
What does the Certificate of Analysis (CoA) for DSIP contain?
The batch-specific CoA for DSIP shows an HPLC purity of 99% or higher, identity confirmation via mass spectrometry, the batch number and the net peptide content in milligrams per vial. The CoA is published on the product page, so you can review it before ordering.
How do you verify the purity of peptides?
Every batch is HPLC-tested by an independent external laboratory to a purity of 99% or higher, with identity confirmation via mass spectrometry. The batch-specific Certificate of Analysis is published on every product page.
How quickly is my order delivered and which carriers do you use?
Orders placed before 15:00 CET are shipped the same working day from the Netherlands via PostNL, including on Saturdays. Delivery within the EU typically takes 2-5 working days, fully tracked. Every package is shipped in neutral, unbranded packaging with no visible references to peptides.
Does MyPeptidesLab offer bulk or wholesale orders for peptides?
Yes, we supply bulk and wholesale quantities to verified research facilities. For inquiries, you can email support@mypeptideslab.com with your specifications.
