The DSIP ladder in figures

DSIP is listed in 3 sizes, 2mg to 15mg a vial, every one a sealed box of 10 vials priced in GBP: £17.10 for DS2 (2mg x 10vials) up to £48.20 for DS15 (15mg x 10vials), which is £1.71 to £4.82 a vial.

Per mg the cheapest size is DS15 (15mg x 10vials) at £0.321 /mg and the dearest is DS2 (2mg x 10vials) at £0.855 /mg, 62 percent apart. The per-mg figure falls at every step up in vial size, so the largest vial, DS15, is also the best priced.

Every size is DAP, delivered in the United Kingdom, tracked, freight included on orders of £1,000.00 and over, quoted at checkout below that; the desk confirms the date for each size when it acknowledges the order.

What every batch of DSIP is released against

The 3 sizes share one specification; the size changes the fill, never the limits: purity: not less than 98.0 percent by RP-HPLC, area normalisation at 220 nm; identity: retention time by RP-HPLC against the reference standard, confirmed by ESI-MS; related substances: any single related substance not more than 1.0 percent; water: not more than 8.0 percent by Karl Fischer; content: labelled peptide content per vial, plus or minus 5 percent by weight. Every batch is tested against the whole list before release and its certificate carries each result beside its limit; the batch number on the certificate is the one on the vial label.

DSIP: what buyers ask

Which size of DSIP costs least per mg?

DS15, 15mg x 10vials, at £0.321 /mg; a box of it is £48.20, £4.82 a vial. It is also the largest vial listed.

What does the cheapest box of DSIP cost, and the dearest?

£17.10 for DS2 (2mg x 10vials), £1.71 a vial, and £48.20 for DS15 (15mg x 10vials), £4.82 a vial, in GBP per sealed box of 10. Freight included on orders of £1,000.00 and over, quoted at checkout below that.

When can DSIP be delivered?

Every size is DAP, delivered in the United Kingdom, tracked; the date for each size is confirmed when the order is acknowledged.

Do all 3 sizes of DSIP meet the same specification?

Yes. Each size is released against the one list on this page (purity, identity, related substances, water, content); the box size changes the fill per vial and nothing else. Each box carries its own batch number and the certificate for that batch is on file.

Can sizes of DSIP be mixed in one order?

Yes. One sealed box is the smallest quantity per size, the order as a whole must reach £300.00 GBP (£100.00 on a first order), and boxes of any size, or of any other compound, count toward it. A single order takes a volume discount on its goods: 5 percent from £5,000.00, 10 percent from £10,000.00, 15 percent from £20,000.00 and 20 percent from £50,000.00. Lifetime paid spend also moves the account up: Silver from £5,000.00 takes 3 percent off goods, Gold from £15,000.00 takes 6 percent off goods, Platinum from £50,000.00 takes 10 percent off goods, Diamond from £100,000.00 takes 15 percent off goods. Checkout takes the better of the two, never both.
