what is dsip?
DSIP is a synthetic nine-amino-acid peptide (a nonapeptide) known as delta sleep-inducing peptide, a name that reflects the waveform observed in the animal model where it was first characterized. Verve supplies it as a research compound for laboratory use only, not for human or veterinary use.
DSIP (delta sleep-inducing peptide) is a synthetic nonapeptide, a nine-amino-acid sequence first isolated during neuropeptide fractionation studies and named for the electroencephalographic waveform observed in the animal model where it was characterized. Verve supplies it as a high-purity research compound for laboratory neuromodulation research.
In research use, DSIP serves as a reference nonapeptide in studies of neuromodulatory signaling, blood-brain-barrier peptide transport, and neuroendocrine pathway regulation in cellular and pre-clinical models. Verve's DSIP is manufactured in the United States, screened by HPLC to a 99%+ purity standard, and shipped with a published batch-level certificate of analysis.

how pure is dsip?
purity, third-party testing & the certificate of analysis
Every batch of verve DSIPis synthesized and vial-filled in the United States and screened by an independent, accredited laboratory. Chromatographic purity and quantity are measured by HPLC-UV/VIS; where the panel includes them, endotoxin is screened by LAL and sterility by USP <71>, with the sterility result reported as no growth detected or as pending while the culture is still running. Products are manufactured to a 99%+ purity standard where stated.
Published certificates for the lots currently in our COA library cover part of the range; a published report for this compound is not in the library yet. Orders placed Monday–Friday ship by 2pm CT, free over $100, with damage protection in transit and full US tracking.
