02Lyophilized Product Format

Where applicable, Royal Peptides research materials are supplied in lyophilized form.

Lyophilization is a freeze-drying process used to remove moisture from material under controlled conditions.

Material appearance may differ between compounds and production lots
Lyophilized material may appear as a cake, film, or fragmented material
The quantity of visible material may appear small relative to vial size
Visual appearance alone does not establish identity or purity

03Storage & Laboratory Handling

Storage requirements may vary by compound, formulation, and production lot. Refer to the product label and available product-specific documentation.

Protect research materials from excessive heat
Limit unnecessary exposure to direct light and moisture
Keep containers securely closed when stored
Follow product-specific temperature requirements when provided
Use appropriate laboratory contamination-control procedures

04Packaging & Quality Documentation

Packaging components may vary slightly between production lots. This can include vial closures, cap styles, label positioning, and external packaging.

Check the product label and lot identifier before laboratory use
Inspect the vial and closure for visible shipping damage
Packaging design may differ between batches
Lot-specific analytical documentation may be available in our COA library

Compound Profile

What Is DSIP?

DSIP (delta sleep-inducing peptide) is a nine-residue neuropeptide, Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu, first isolated in 1977 from cerebral venous blood of rabbits in induced slow-wave sleep.

It remains a reference compound in research on sleep architecture, stress-hormone regulation and circadian signaling. Royal Peptides offers DSIP as a 5mg single vial or as 5mg and 10mg ten-vial kits.
