About this line

DR20 is Dermorphin(dp) at 20mg a vial: 10 sealed vials to the box, 200 mg in total, $177.01 the box or $0.885 /mg. Of the 4 Dermorphin(dp) sizes on the list it is the one that costs least per mg. Across the range the per-mg figure runs from $0.885 /mg on DR20 to $1.70 /mg on DR2, a gap of 48 percent: the larger the vial, the less each mg costs.

DR20 is a special order: it is brought in on a 50-box minimum and not held in stock. None of the 4 sizes is in stock now: 4 special orders on a 50-box minimum. Every vial label repeats the code and the batch number, so the certificate can be pulled from the label alone.

At $177.01 a box, the 50-box minimum on DR20 comes to $8,850.50 of goods, past the $300.00 CAD order minimum on its own. Below it on the ladder is DR10 (10mg x 10vials) at $0.974 /mg, 10 percent over this size.

What the certificate for DR20 must show

Each box of DR20 comes from one batch, and that batch’s certificate carries the lines below before it is released. The limits are the release specification; the sequence notes are worked out from the chain on the sheet.

Purity. Not less than 98.0 percent by RP-HPLC, area normalisation at 220 nm, with the main peak named on the chromatogram.
Identity. Retention time by RP-HPLC against the reference standard, confirmed by ESI-MS. The spectrometer should place the protonated molecule at m/z 803.9 for 1+, m/z 402.5 for 2+, against a calculated average mass of 802.9 (C40H50N8O10); the measured mass should agree to within a unit.
Related substances. Any single related substance not more than 1.0 percent. This chain has no methionine, tryptophan, cysteine, asparagine or glutamine, so what remains is deletion sequences from synthesis, one residue short.
Main peak position. On C18 the main peak comes about mid-gradient; the backbone’s Kyte-Doolittle average is -0.11 over 7 residues and the net charge near neutral is about +1.
Terminus. The chain ends in an amide, and the mass on the certificate includes it.
Water. Not more than 8.0 percent by Karl Fischer.
Fill. Labelled peptide content per vial, plus or minus 5 percent by weight.
Endotoxin. Reported on the certificate by LAL where the line is tested.
Batch, dates, signature. The batch number as printed on the vial label and the packing list, the date of manufacture, the retest date (24 months from manufacture at minus 20 degrees Celsius, retest date on every certificate), and the release signature.

Look up a batch number to pull the certificate on file; the signed copy travels with the shipment.

$177.01 in CAD for the sealed box of 10 vials, which is $17.70 a vial and $0.885 /mg. Freight included on orders of $1,000.00 and over, quoted at checkout below that.

Is DR20 the cheapest Dermorphin(dp) per mg?

Yes. At $0.885 /mg it is the lowest of the 4 sizes; the next is DR10 at $0.974 /mg.

Can DR20 ship today?

Not from stock. DR20 is a special order: it is brought in on a 50-box minimum and not held in stock, and the date is confirmed when the order is acknowledged.

What is in a box of DR20?

10 sealed vials, each holding 20mg of Dermorphin(dp), 200 mg in the box, packed as a lyophilised powder with the code, the strength and the batch number on every label. The box is the unit of sale and is not opened.

What is on the certificate for a batch of DR20?

In order: purity, identity, related substances, main peak position, terminus, water, fill, endotoxin, batch, dates, signature. Each line carries its limit and the batch’s result; the list above is the whole of it, and the batch number on it matches the vial label.

How is DR20 stored after delivery?

Minus 20 degrees Celsius, protected from light and moisture. Short transit at ambient is tolerated. Shelf life is 24 months from manufacture at minus 20 degrees Celsius, retest date on every certificate.

What is the smallest order of DR20?

50 sealed boxes: DR20 is a special order, brought in on a 50-box minimum. The order as a whole must reach $300.00 CAD ($100.00 on a first order), and any mix of lines counts toward it.

Does the DR20 price come down with volume?

Yes, by the order and by the account, and checkout takes the better of the two, never both. 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. On DR20 that runs from $177.01 at list to $141.61 a box at 20 percent off.
