Check formulation: Lyophilized powder requires reconstitution before use. Pre-mixed solutions are more convenient but may have a shorter shelf life and higher prices.
Compare per-mg cost: Different strengths and quantities make direct price comparison difficult. Calculate the per-milligram cost to find the true best value.
Verify COAs: Look for vendors that publish per-batch Certificates of Analysis from named, accredited labs. Every vendor on this page is verified for endotoxin testing — not just HPLC purity.
Schoenenberger & Monnier first isolated and characterized DSIP in 1977 (PNAS 74(3):1282-6, PMID 265572). Graf & Kastin's 1984 review (Neurosci Biobehav Rev, PMID 6145137) summarized the first decade of work, noting reported effects on sleep, pain, and stress but also substantial inconsistency across labs and species. Schneider-Helmert (Eur Neurol 1986, PMID 3792404) reported sleep normalization in 18 middle-aged and elderly chronic insomniacs given DSIP over one week — small, open, and never replicated at scale. Schneider-Helmert et al. (Dtsch Med Wochenschr 1987, PMID 3582201) explored phase-shifted insomnia. Kovalzon & Strekalova (J Neurochem 2006, PMID 16539679) summarized the field as a 'still unresolved riddle,' noting that no DSIP receptor or gene has been identified. No Phase 3 trials, no FDA approval, no modern controlled replication.
