Description
What is DSIP?
Delta-sleep-inducing peptide is one of the oldest characterized neuropeptides — isolated in 1977 from the cerebral venous blood of rabbits in induced slow-wave sleep. The nonapeptide has been studied for nearly five decades for its association with delta-wave (deep) sleep promotion, giving it one of the longest continuous research histories in the catalogue.
Beyond sleep architecture, the literature connects DSIP to stress-hormone modulation (it blunts corticotropin release), pain threshold studies, and circadian research. Its mechanisms remain genuinely open questions — part of why it continues to attract new attention.

Why buy DSIP as a 10-pack
Single-vial retail pricing punishes people who actually use volume. Our 10-pack format works out to $35.00 per vial — up to 30% below typical single-vial retail in Canada — and because every vial ships from one production lot, a single certificate of analysis covers your entire supply. One order, one batch, zero between-vial variance.
Quality & testing
Every lot is independently tested for identity (mass spectrometry) and purity (HPLC) before release. Packs ship cold-packed with tracking from our Canadian facility, and each order automatically includes one free vial of bacteriostatic water.
