DSIP

DSIP is supplied as a catalogued research material in 5mg.

The literature identity of DSIP maps to the free nonapeptide shown here. That mapping does not establish the salt, counter-ion, net peptide content or purity of the catalogue vial; those attributes require a matching batch CoA [1].

Chemical properties and registry information

Registry values apply only to the specific molecular entity, sequence, termini and material form. Batch records take precedence over family-level literature identifiers.

Major databases (PubChem, ChEMBL, DrugBank) list a molecular formula of C35H49N9O15 and MW of ~847.85 g/mol. However, the sequence WAGGDASGE contains 10 nitrogen atoms, and first-principles calculation for the neutral molecule yields C35H48N10O15 (MW ~848.83 g/mol), which is more consistent with the original literature (MW ~849 Da).

Research background and published evidence

Published research

DSIP has been examined in historical physiological and sleep-research models. Small controlled studies reported limited or inconsistent observations, making the literature suitable for research context rather than a product-performance claim [2,3].

Current scientific understanding

The cited human studies were small and did not establish a reliable therapeutic effect. They do not demonstrate safety, efficacy, dosage, administration, suitability, or medicine status for this catalogue batch [2,3].

No medicinal authorization is inferred from the DSIP name or literature record. Research-use labelling does not replace the purchaser’s substance- and jurisdiction-specific legal review.

Technical comparison

Quality and testing

Quality information is batch- and presentation-specific. Use only the report linked to the exact size and lot. A report listed for another size, lot or similarly named material must not be treated as evidence for this product.

Chromatographic area purity, identity, net peptide or analyte content, water or counter-ion content, sterility, endotoxin and elemental impurities are different measurements. One result does not establish the others. Only tests supported by a visible, matching report should be regarded as available.

Laboratory handling and storage

Store and handle only under the conditions stated on the product label, batch CoA and SDS. Keep the container secured, correctly identified and protected from contamination. Do not infer storage, solvent compatibility or stability from a related compound.

Laboratory preparation, analytical-method selection, risk assessment, personal protective equipment and waste disposal should follow the applicable SDS and the institution’s approved procedures.

Frequently Asked Questions

Do the CAS number and PubChem CID apply to every batch form?

Only when the exact sequence or structure, termini, conjugation, salt or counter-ion and hydration state match. The batch CoA and SDS govern; a related-compound identifier must not be substituted.

What does an analytical purity result mean?

It is method- and report-specific. For example, an HPLC area percentage is not automatically the same as identity, net content, sterility, endotoxin status or absence of elemental impurities.

How should the material be stored and handled?

Follow the exact label, batch CoA and SDS together with the institution’s risk assessment. Use only storage and stability information linked to the exact material form and batch.
