All research guides- What is DSIP? Delta sleep-inducing peptide in published researchDSIP is the nonapeptide Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu, isolated in 1977 from the cerebral venous blood of rabbits in which sleep had been induced by electrical stimulation. Infused into the brain of rabbits it increased slow-wave EEG activity. Later animal studies reported effects on stress hormones, seizures, pain and recovery of movement after stroke in rats. In a small double-blind study in 16 people with chronic insomnia, effects were weak and judged unlikely to be of major benefit. No gene, precursor protein or receptor for DSIP has been identified. Vitality Peps supplies DSIP for in vitro laboratory research only.8 min read
- How to Store and Handle Research PeptidesLyophilised research peptides are stored in the refrigerator at 2 to 8 °C, or frozen at -20 °C for longer storage, sealed and protected from light. After reconstitution with [bacteriostatic water](/product/bacteriostatic-water-10ml) the solution is kept refrigerated, never shaken, and never refrozen.5 min read
- How to Read a Peptide COA (Certificate of Analysis)A peptide certificate of analysis shows what an independent laboratory found in one specific batch: identity confirmed by mass spectrometry, purity measured by HPLC, and the measured quantity against the labelled amount. Read it by checking the identity result first, then the purity figure and the test date.6 min read
- Where to Buy Research Peptides in Europe: A 2026 Buyer's ChecklistThe safest way to buy research peptides in Europe is from a supplier that stocks in the EU, publishes an independent lab report for each batch, ships in discreet tracked packaging, accepts regulated payment methods and states clearly that the products are for research use only. Ordering inside the EU avoids customs handling entirely.7 min read
- What your vial should look likeA sealed research peptide vial normally holds a white to off-white lyophilized cake or powder under an intact stopper and crimp cap. Pre-filled pens and nasal spray kits arrive sealed, with their documented appearance on the product page. Appearance never proves identity or purity; the COA for the batch does.4 min read
