DSIP
DSIP is delta sleep-inducing peptide, the nonapeptide Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu. VaultLabs supplies a 5 mg lyophilized vial as reference material. The historical name does not make the vial a sedative drug. It is not an approved medicine.

Key facts
- Nine residues. Sequence WAGGDASGE.
- CAS 62568-57-4. Formula C35H48N10O15. Molecular weight 848.81 g/mol.
- Catalogue fill is 5 mg.
- The name is historical. The vial is a research peptide, not a sleep medicine.
- Reviews of DSIP disagree about the original observations. That disagreement is why the lot record matters more than the nickname.
- Supplied for laboratory research. Not for human use.

What DSIP is
DSIP is a short peptide with a long nickname. The sequence is nine residues, CAS 62568-57-4, about 849 Da. A review titled as an unresolved riddle is useful context and a warning: do not treat the name as a function. The VaultLabs unit is lyophilized reference material at 5 mg.

How VaultLabs catalogues it
One fill: DSIP 5mg. It is not Semax and not Epithalon. The monograph is /compounds/dsip. Confirm the nonapeptide sequence on the lot record before the unit leaves quarantine.
Short peptides with similar masses are easy to swap on a crowded shelf. Write DSIP, 5 mg and the sequence shorthand WAGGDASGE on the inventory row.
Lots and receiving
Each sealed unit carries its own lot number. The current catalogue certificate for that lot is published on the batch page and states purity of at least 99.8 percent on the same VaultLabs template used for the rest of the lyophilized catalogue. A certificate for one fill does not qualify another fill. A certificate for a blend does not qualify a single-sequence vial that happens to share part of a name. Do not copy a purity figure from a different product, from a photograph of another vial, or from a paper into the receiving file. Match the printed name, the nominal mass and the lot number on the vial to the published record. If those three do not agree, hold the unit and ask for the document that belongs to that unit before it leaves quarantine. Enter the printed lot at batch verification.
Storage and research-use boundary
Keep the sealed lyophilized vial at 2 to 8 degrees Celsius, protected from light and from moisture, until it is opened under the laboratory's own procedure. Allow the closed vial to reach room temperature before the seal is broken, so water from humid coastal air does not condense on the dry cake. Bacteriostatic water and sterile water are separate catalogue lines. They are not packed inside the peptide box, because the receiving laboratory chooses the medium in its own procedure. VaultLabs does not publish a preparation method on this page. After the seal is opened, solution age, container and freeze cycles are controlled by the laboratory, not by the catalogue page.
The material is supplied for in vitro laboratory research only. It is not for human or animal consumption. It is not an approved medicine, not a finished cosmetic, and not a personal-use item. Papers cited on the compound monograph describe other people's experiments. Those papers are not a description of what this vial will do, and they are not instructions for any person or animal. A buyer who needs a registered medicine should use a licensed pharmacy channel. This page exists so a procurement officer in the UAE can identify the catalogue line, the fill, the price band and the paperwork before raising an order.
