What is — DSIP
DSIP (delta sleep-inducing peptide) is a small endogenous nonapeptide first isolated from mammalian brain material and widely used as a reference compound in neuroscience and physiology laboratories. Peptworks supplies it as a lyophilised research reagent, 5 mg per vial, at >=98% HPLC purity with an independent per-batch Certificate of Analysis. It is offered for Research Use Only (RUO) and is not a medicine, supplement, cosmetic or medical device, and is not intended for human or animal consumption.
In preclinical and in-vitro research models, DSIP is studied as a signalling peptide associated with the modulation of central nervous system activity, with particular research attention on electroencephalographic (EEG) delta-wave patterns. Investigators also examine its interaction with neuroendocrine pathways, including the hypothalamic-pituitary-adrenal (HPA) axis, and its possible role in stress-response and thermoregulatory signalling. Its precise molecular targets remain an open research question, which is part of why it is used as a tool compound rather than a characterised agonist of a single receptor.
Research
- Sleep architecture and EEG delta-wave research in animal models
- Neuroendocrine and HPA-axis / stress-response studies (preclinical)
- Thermoregulation and circadian signalling research
- Nociception and analgesia models (in-vitro / animal)
- Oxidative-stress and cellular-protection assays
- Peptide stability, formulation and analytical method development
Advantages
- Serves as a well-known reference peptide for standardising sleep- and EEG-focused laboratory protocols
- Used as a tool compound to probe delta-wave activity in rodent electrophysiology research
- Applied in preclinical studies of stress-response and neuroendocrine signalling pathways
- Supports comparative research on thermoregulatory and circadian model systems
- >=98% HPLC purity and per-batch CoA reduce lot-to-lot variability in experimental design
- Lyophilised 5 mg format offers stable, reconstitution-flexible handling for bench workflows
Safety
- As a laboratory reagent, DSIP is not administered to humans, so no human safety profile is claimed
- Preclinical literature generally reports low acute toxicity in animal models, though findings vary by study design
- Handle as a research chemical: avoid inhalation, ingestion and skin/eye contact, and use appropriate PPE
- Reconstituted peptide is subject to degradation; observe cold-chain and stability handling to preserve assay integrity
- Not evaluated for and not to be used in any diagnostic or therapeutic context
Ideal for
- Academic and private neuroscience or physiology laboratories running preclinical studies
- Resellers and distributors building a bulk or white-label research-peptide catalogue in the EU
- Contract research organisations (CROs) needing consistent, CoA-backed lots
- Analytical and formulation teams developing peptide assay or stability methods
- Buyers requiring EU-stocked inventory with fast intra-community delivery and no customs
This product is a laboratory reagent supplied strictly for research. It is not a medicine, food or supplement and is not for human or veterinary use. It must be handled by qualified professionals under laboratory conditions.
Frequently asked questions
Where can I buy DSIP in bulk in the EU?
Peptworks is a B2B wholesale and white-label supplier with DSIP 5 mg vials already stocked inside the EU. Orders ship intra-community in 3-5 business days with no customs. Orders start from a 4-vial pack per reference. This is a research reagent sold for Research Use Only, not to end consumers.
What is the wholesale DSIP price per vial?
DSIP 5mg has two public per-vial prices: €28.90 in a 4-vial pack and €18.00 from 10 vials of this reference (box price). There are no volume tiers. Shipping is free on orders from €500 (€24.90 below), inside the EU with no customs.
Do you offer DSIP as white-label?
Yes, in the white-label sense: DSIP comes in unbranded vials, with no brand on the vial, so you can resell it under your own label. Peptworks does not print or apply labels. Every batch is tested by an independent lab and ships from EU stock with no customs.
What is the minimum order for DSIP?
The minimum is a 4-vial pack per reference; from 10 vials of a reference the lower box price applies. Vials ship in boxes of 10. There are no volume tiers, and orders from €500 ship free.
How is the DSIP CoA verified?
Every batch has an independent Certificate of Analysis covering HPLC purity (>=98%) and heavy metals. Each box carries a unique QR that links directly to that batch's CoA, verifiable through Peptworks, so your customers can authenticate the exact lot they received.
How do I pay and how fast does DSIP ship?
Payment is in crypto: USDC or USDT (Polygon or Base) or Bitcoin — paying in crypto is what keeps our prices this tight, with no card or bank fees. there is no card checkout on the site. Because stock sits inside the EU, DSIP ships intra-community in 3-5 business days with no customs clearance. The site is available in 10 languages (ES, EN, DE, FR, PT, IT, NL, PL, CS, EL).
