DSIP (Acetate) 5mg: What You’re Actually Buying
DSIP (Acetate) 5mg is a standard vial size for this well-known synthetic nonapeptide, more formally known by its INN, emideltide. Before comparing listings, it’s worth understanding exactly what the compound is, why the salt form matters, and what separates a well-documented supplier from a thin one.
Research use only. DSIP is sold for laboratory research and analytical work. It is not a medicine, supplement or food, and it is not intended for human or veterinary use.
What Is DSIP?
DSIP, delta sleep-inducing peptide, is a synthetic linear nonapeptide with the sequence H-Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu-OH (one-letter: WAGGDASGE). It’s studied in laboratory research contexts including peptide characterisation, HPLC method development and mass-spectrometry workflows.
Key identifiers:
- Preferred substance name: Emideltide
- Sequence: H-Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu-OH (9 residues)
- CAS number: 62568-57-4
- PubChem CID: 68816
- Molecular formula: C35H48N10O15
- Average molecular weight: approximately 848.82 g/mol
- Form: lyophilised laboratory material, typically supplied in sealed vials
Why the Acetate Form Matters
A listing specifying DSIP (Acetate) 5mg is telling you something important: DSIP can be supplied bound to different counter-ions, most commonly as an acetate or trifluoroacetate salt, or unrelated to a specific counter-ion at all. Each form has a different formula weight, which means the “5mg” figure on the label can refer to different amounts of net peptide depending on which form you’re buying.
A credible listing should confirm:
- Whether the supplied material is uncountered DSIP, DSIP acetate, DSIP trifluoroacetate, or another form
- That the counter-ion content has been assessed, since it affects net peptide content versus total vial weight
- That chromatographic purity and net peptide content are presented as separate figures, not conflated into one
This is a genuinely easy thing for a weaker listing to gloss over, so treat any product page that states a bare “purity %” with no counter-ion detail as a page you should ask more questions of.
DSIP (Acetate) 5mg for Sale: What to Check Before You Buy
When comparing DSIP (Acetate) 5mg for sale listings, work through this checklist:
- Batch-specific Certificate of Analysis (COA), ideally accessible via a QR code or direct link tied to the specific vial you’re ordering, not a generic PDF reused across batches
- Purity specification of at least 98-99% chromatographic purity, confirmed by the stated analytical method
- Identity confirmation via mass spectrometry, consistent with the DSIP sequence and stated salt form
- Safety Data Sheet (SDS) available alongside the COA, to support correct laboratory handling
- Clear counter-ion documentation, distinguishing chromatographic purity from net peptide content
- Research-only labelling, explicitly stating the product isn’t for human or animal use, and referencing MHRA compliance where relevant
DSIP 5mg for Sale: Comparing Standard and Enhanced Specifications
Some UK suppliers offer tiered specifications for the same nominal size. When comparing DSIP 5mg for sale listings, you may find:
- Standard/regular grade: typically ≥99% chromatographic purity, suitable for most routine laboratory and analytical work
- Enhanced/premium grade: an additional preparative HPLC purification stage and a more stringent bacterial endotoxin (LPS) testing specification, aimed at more demanding laboratory workflows
Neither tier is inherently “better” for every use case; the right choice depends on your specific study requirements. What matters is that the supplier states plainly what differentiates the tiers, backed by documentation, rather than using “premium” as a marketing label with no analytical basis behind it.
Specifications Table
| Specification | What a credible listing should state |
|---|---|
| Sequence | WAGGDASGE (9 residues), free amino and carboxylic termini |
| CAS number | 62568-57-4 |
| Salt form | Acetate, trifluoroacetate, or uncountered, stated explicitly |
| Purity | ≥98-99% chromatographic purity, method specified |
| Identity | Mass spectrometry consistent with sequence and salt form |
| Documentation | Batch-specific COA and SDS, accessible per order |
| Labelling | “Research use only,” explicit MHRA-compliance language |
DSIP 5mg in UK: Sourcing and Delivery
Buying DSIP 5mg in UK from a domestic supplier reduces customs delay risk and keeps the material within a shorter, more temperature-controlled supply chain. Look for:
- Insulated or temperature-controlled packaging where the product specification calls for it
- Tracked delivery with dispatch times clearly stated
- A registered UK company name, company number and physical address in the footer, not just a storefront
- Direct links to the batch COA and SDS on the product page itself, rather than “available on request”
Storage and Handling
- Store lyophilised material as directed on the applicable COA or SDS, typically cold, dry and protected from light
- Follow the specific reconstitution solvent, buffer and concentration stated in your batch documentation rather than a generic instruction
- A credible research supplier will explicitly state it does not provide dosage, administration or human/animal use advice, since this isn’t its role
- Avoid repeated freeze-thaw cycles once reconstituted
Supplier Comparison at a Glance
| Factor | Strong supplier | Warning signs |
|---|---|---|
| Documentation | Batch-specific COA + SDS, linked per product | No documentation, or generic reused PDFs |
| Salt form clarity | States acetate/TFA/uncountered explicitly | No counter-ion information given |
| Purity reporting | Chromatographic purity and net peptide content shown separately | Single vague “purity” figure |
| Claims | Explicit “no dosage advice” and MHRA-compliance language | Dosing or administration guidance |
| Business | UK company number, address, phone support | Anonymous storefront |
Frequently Asked Questions
Is DSIP (Acetate) the same as plain DSIP?
They share the same peptide sequence, but the acetate form is bound to a different counter-ion, which changes the total molecular weight and how “5mg” should be interpreted. Always check the COA for the specific form supplied.
Why does purity percentage not tell the whole story?
Chromatographic purity measures how much of the material matches the intended peptide relative to impurities. It’s a separate measurement from net peptide content, which also accounts for water, residual solvents and counter-ion weight.
Is there a recommended dose for DSIP?
No. Reputable research suppliers explicitly state they don’t provide dosage, administration or human/animal use advice, since the product is not approved or intended for that purpose.
What should come with my order?
A labelled vial, plus direct access to that batch’s Certificate of Analysis and Safety Data Sheet.
Final Thoughts
DSIP (Acetate) 5mg is a well-characterised research peptide, but the details that actually differentiate a trustworthy supplier, salt form, net peptide content, and batch-linked documentation, are easy to overlook if a listing doesn’t spell them out. Choose a supplier that treats those details as standard practice, not an afterthought.
