Peptidology has the lowest single-vial DSIP price at $3.93/mg among 33 COA-verified vendors on Disclosed Labs. Bulk or multi-vial deals may be lower. That's 65% less per mg than the most expensive option.
What is the price range for DSIP?
Research-grade DSIP ranges from $3.93/mg to $11.19/mg across 22 verified sources, a 65% spread per mg.
How are DSIP prices verified on Disclosed Labs?
Every listed vendor holds a Grade C or better trust score, computed independently from lab Certificates of Analysis — not from payments or sponsorships. Prices are scraped and fact-checked daily. Vendors cannot pay to improve their ranking.
DSIP is among peptides under FDA review; if added to the Category 1 (503A)list it would require a prescription. In April 2026 the FDA removed 12 peptides from Category 2, but removal does not place them on the Category 1 list or authorize compounding — they remain in a regulatory gray zone. The FDA's Pharmacy Compounding Advisory Committee is advisory and meets July 23–24, 2026 to review nominations and make recommendations to the FDA; the FDA issues any final rule later.
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. Use the Full safety panel filter to require endotoxin, sterility, and heavy-metals testing on the current batch — 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.
