Description

For Research Use Only. This product is supplied exclusively for laboratory research and is not intended for human or veterinary use.

DSIP (Delta Sleep-Inducing Peptide) Research Material

Delta sleep-inducing peptide (DSIP) is a synthetic nonapeptide with the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu. It was originally described in sleep-related experiments and has since been used in exploratory neuroendocrine research.

The DSIP literature is old, limited and inconsistent. A specific precursor gene and a dedicated DSIP receptor have not been firmly established, and published sleep findings should not be presented as settled clinical evidence.

Technical Specifications

Independent Batch Testing

Every current ZENTRA DSIP batch is independently tested and records an HPLC purity result above 99%. Use the batch number printed on the product label to locate the corresponding third-party report in our Batch Verification and COA Centre. Researchers should consult the individual report for the exact analytical methods, result and testing date for their supplied batch.

DSIP Research Context

Early studies examined electroencephalographic sleep variables and neuroendocrine responses. Reviews noted variability between species, preparations and study designs, with no single mechanism accounting for all reported observations.

The responsible interpretation is that DSIP is a historical and exploratory research peptide. ZENTRA does not describe it as a proven sleep treatment and provides no dosing or human-use guidance.

Storage and Handling

Keep unopened lyophilised material at approximately -20°C for long-term storage or 2-8°C for short-term laboratory storage. Protect from light, moisture and repeated temperature changes.

DSIP Research FAQs

What is DSIP?

DSIP is a nine-amino-acid synthetic research peptide originally associated with delta-sleep experiments.

What is its sequence?

Its sequence is Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu, abbreviated WAGGDASGE.

Is there a confirmed DSIP receptor?

No dedicated receptor has been firmly established.

Does the research prove a sleep benefit?

No. Findings are limited, dated and inconsistent, so the evidence should be treated as exploratory.

How is purity verified?

The current batch is independently HPLC tested above 99%, with its report available through batch verification.

Is DSIP intended for human use?

No. It is supplied solely for laboratory research and analytical work.
