About this line

ET50 is Epithalon at 50mg a vial: 10 sealed vials to the box, 500 mg in total, £164.82 the box or £0.330 /mg. Of the 2 Epithalon sizes on the list it is the one that costs least per mg.

DAP, delivered in the United Kingdom, tracked, freight included on orders of £1,000.00 and over, quoted at checkout below that; delivery timing is confirmed when the order is acknowledged. 1 of the 2 sizes is held in stock now, 1 made to order; the ladder above marks each one. Every vial label repeats the code and the batch number, so the certificate can be pulled from the label alone.

At £164.82 a box, 2 boxes of ET50 reach the £300.00 GBP minimum, £329.64 of goods, and 1 box clears the £100.00 first-order floor. Any mix of lines counts toward it, so ET50 can make up part of it. Below it on the ladder is ET10 (10mg x 10vials) at £0.404 /mg, 23 percent over this size.

What the certificate for ET50 must show

Each box of ET50 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.
Related substances. Any single related substance not more than 1.0 percent. On this sequence the ones to look for are isoaspartate at the Asp-Gly pair.
Main peak position. On C18 the main peak comes early, on a shallow starting gradient; the backbone’s Kyte-Doolittle average is -1.40 over 4 residues and the net charge near neutral is about -2.
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.
