§ About DSIP

DSIP is a nine-amino-acid peptide historically identified in neuropeptide research. It has been investigated in sleep-state / electrophysiological, circadian, neuroendocrine and signalling research across a heterogeneous experimental literature, much of it historical / preclinical.

PepDirect does not represent DSIP as an established treatment for sleep or any other condition. This product is supplied exclusively for laboratory research use.

§ What does the evidence show?

DSIP has a long experimental research history across cellular, animal and some human research contexts. Reported findings across the literature are not equivalent to established clinical efficacy, and research should be interpreted according to model type and study design. PepDirect does not represent DSIP as an approved treatment for sleep or any other condition.

§ FAQ

What is DSIP?: DSIP is a nine-amino-acid peptide historically identified in neuropeptide research and investigated across sleep-state, circadian and neuroendocrine research contexts.
What does DSIP stand for?: Delta Sleep-Inducing Peptide, a descriptor from its historical research nomenclature. The name reflects the context in which it was first identified rather than an established treatment claim.
How many amino acids are in DSIP?: Nine amino acids (sequence WAGGDASGE).
What areas of research involve DSIP?: Reported research areas include sleep-state / electrophysiological research, circadian research, neuroendocrine signalling and neurotransmitter-related experimental models. The literature is heterogeneous and largely historical / preclinical.
Is DSIP an established sleep treatment?: No. This PepDirect material is laboratory research material only and the page does not represent DSIP as an approved treatment for sleep or any other condition.
How is PepDirect DSIP tested?: Every lot is supplied with lot-specific documentation. HPLC purity is reported on the product hero and full identity information is captured in the lot Certificate of Analysis.
