They took it from the cerebral venous blood of rabbits kept in induced sleep and named it after the delta wave pattern it produced on the EEG of recipient animals. Through the late 1970s and 1980s it was examined in rats, rabbits, cats and humans, which makes it one of the earliest neuropeptides with a sleep literature of its own.\u003c\/p\u003e \u003cp\u003eThe human work is small and dated. Schneider-Helmert and colleagues ran a series of studies in the 1980s in people with chronic insomnia and reported improvements in sleep efficiency in some participants, while other groups found little or no effect. Separate lines of research looked at DSIP and stress, including its relationship with corticotropin and luteinising hormone release, and at withdrawal states. None of these programmes progressed to large controlled trials.\u003c\/p\u003e \u003cp\u003eThe central problem is mechanism. Kovalzon and Strekalova summarised it in the Journal of Neurochemistry in 2006 as a still unresolved riddle: no dedicated receptor and no gene encoding the peptide have been identified, and it is unclear how a peptide of this size crosses into the brain. That is why DSIP remains a research compound with a long history rather than a well characterised one, and why its evidence should be read with that caveat.\u003c\/p\u003e \u003ch2\u003eQuality and testing\u003c\/h2\u003e\n\u003cp\u003eOrigin Peptides vials are filled to a stated milligram content, lyophilised and sealed, with the batch number printed on every vial. Every batch is independently tested for identity and purity before release, and its certificate of analysis is published on the \u003ca href=\"\/pages\/lab-results\"\u003eLab Testing\u003c\/a\u003e page so the report can be matched to the number on your vial.

What is not lawful is selling or advertising it for human use, because the MHRA treats a product presented that way as an unlicensed medicine. That is why this listing, and every listing on this site, is worded for laboratory research and nothing else.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eWhat is the difference between the 5mg and 10mg DSIP vials?\u003c\/strong\u003e The compound, purity standard and testing are identical; the 10mg vial simply contains twice the material. At £59.99 it works out at £6.00 per mg against £10.00 per mg for the \u003ca href=\"\/products\/origin-peptides-dsip-5mg\"\u003eDSIP 5mg vial\u003c\/a\u003e, so it is the better value format for longer research programmes.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eHow does DSIP compare with Selank and Semax?\u003c\/strong\u003e All three sit in the Cognitive and Sleep series but come from different research traditions. DSIP is a naturally occurring sleep associated peptide; \u003ca href=\"\/products\/origin-peptides-selank-5mg\"\u003eSelank\u003c\/a\u003e is a synthetic analogue of the immune peptide tuftsin studied for anxiety related behaviour, and \u003ca href=\"\/products\/origin-peptides-semax-5mg\"\u003eSemax\u003c\/a\u003e is an ACTH 4-10 analogue studied for cognition.

On arrival keep it sealed, refrigerated at 2 to 8C and away from light, or at -20C for storage beyond a few months. Lyophilised peptides are reconstituted in the laboratory with a sterile diluent such as \u003ca href=\"\/products\/origin-peptides-bacteriostatic-water-10ml\"\u003eOrigin Peptides bacteriostatic water\u003c\/a\u003e; no reconstitution or usage guidance is given on this site.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eHow fast is delivery?\u003c\/strong\u003e Orders placed before the daily cut off are despatched the same working day by tracked delivery, usually arriving within two to three working days in the UK, with a next day upgrade at checkout. Parcels leave in plain outer packaging with no reference to the contents.
