DSIP FAQ
Where can I buy DSIP peptide?
Blank Peptides has DSIP for sale in 10mg vials, made in our cGMP labs in the USA. A lot-matched certificate of analysis is published before you order. We sell research material directly to researchers with no prescription step, and processing time is within 1 business day.
What is DSIP?
DSIP stands for delta sleep-inducing peptide, a nonapeptide first isolated from rabbit cerebral venous blood in 1977. Research has examined its influence on delta wave activity in EEG studies, along with corticotropin and somatostatin interactions. Despite nearly fifty years of work, its endogenous receptor has never been definitively identified, which keeps it interesting to researchers.
What purity is your DSIP, and who verifies it?
Greater than 99%. Every lot is assayed by HPLC and mass spectrometry in our own laboratory, then confirmed independently at Freedom Diagnostics or Horizon Analytical. Bacterial endotoxin testing runs at batch release. The COA corresponds to the lot number printed on your vial, not a representative sample.
How do I reconstitute DSIP 10mg?
Add 1mL of bacteriostatic water for a 10mg/mL solution, matching our catalogue standard of 1mL per 10mg. Introduce the solvent against the glass wall rather than onto the powder, then swirl slowly until clear. Do not shake the vial; foaming shears peptide and makes accurate withdrawal harder.
How should DSIP be stored?
Sealed lyophilized vials at -20C, dark and dry. Freeze-dried material tolerates ambient shipping temperatures without degradation. After reconstitution, keep it refrigerated at 2 to 8C and use within a few weeks. DSIP does not hold up especially well in solution, so aliquoting is worth the extra minute if the protocol runs long.
How is DSIP shipped and packaged?
From inside the USA in plain outer packaging with no compound names printed on it. Processing time is within 1 business day and tracking is emailed at label creation. Vials ship padded against impact rather than temperature. Cracked glass or a disturbed cake gets replaced once support sees photos.
DSIP vs epithalon for circadian research?
Different angles on overlapping territory. DSIP research focuses on sleep architecture and delta wave activity directly. Epithalon work centres on pineal function and melatonin regulation, which touches circadian rhythm from the hormonal side. Studies modelling both tend to be looking at where the two intersect.
Is DSIP approved for human use?
No. DSIP has no FDA approval, is not a drug or supplement, and is not intended for human or veterinary use. It is supplied as a research chemical for laboratory work only. Placing an order confirms you are a qualified researcher and the material will be handled in a research setting.
