# Best DSIP supplier UK?

A good UK DSIP supplier should offer a lot-specific Certificate of Analysis, a lot number on the vial and transparent pricing. Sable Peptides provides all three, sells DSIP from £9.98 for 2 mg, guarantees the lowest UK price checked daily, and ships next-day. Research use only.

## What it is

DSIP is delta sleep-inducing peptide, a nonapeptide studied in neuropeptide research. Reference data: CAS 62568-57-4, formula C35H48N10O15, molecular weight 848.8 g/mol.

Sizes and prices at Sable (checked 2026-10-15): 2 mg (£9.98), 5 mg (£11.56). Supplied as a lyophilised (freeze-dried) powder in a sealed vial.

## How prices are checked

we compare our price daily against genuine, established UK suppliers only (not marketplaces or unverifiable listings) and guarantee the lowest UK price. If you find a lower like-for-like price from such a supplier, we match it. In our 10 October 2026 snapshot of 12 UK-facing retailers, the median list price for 5 mg was £15.95 (range £11.56 to £29.95); Sable listed it at £11.56. Method and seller types are explained on the pricing methodology page.

## Documentation

Every lot has its own Certificate of Analysis and every vial carries a printed lot number, so the paperwork matches the vial. You can request the CoA for the lot you will receive before you order. A useful CoA names the lot, the test method (usually HPLC for purity and mass spectrometry for identity), the result and the date.

## Ordering

we have operated since 2019, ship next-day across the UK, and take payment by Pay by Bank via Wallid. Research materials can't be returned, but anything faulty or damaged in transit is refunded or replaced.

## Research use only

DSIP is sold for in-vitro laboratory research. It is not a medicine, is not for human or animal use, and nothing here is advice on use.
