Tirzepatide 20mg x 10 vials

TR20 is Tirzepatide at 20mg a vial: 10 sealed vials to the box, 200 mg in total, £48.98 the box or £0.245 /mg. Of the 12 Tirzepatide sizes on the list it ranks 9th by price per mg; TR120 (120mg x 10vials) costs least at £0.207 /mg, 16 percent under this line. Across the range the per-mg figure runs from £0.207 /mg on TR120 to £0.389 /mg on TR5, a gap of 47 percent: the larger the vial, the less each mg costs.

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. 3 of the 12 sizes are held in stock now, 3 made to order and 6 special orders on a 50-box minimum; 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 £48.98 a box, 7 boxes of TR20 reach the £300.00 GBP minimum, £342.86 of goods, and 3 boxes clear the £100.00 first-order floor. Any mix of lines counts toward it, so TR20 can make up part of it. Below it on the ladder is TR15 (15mg x 10vials) at £0.259 /mg, 6 percent over this size. Above it on the ladder is TR30 (30mg x 10vials) at £0.231 /mg, 6 percent under this size.

A recent batch of TR20 was released by an independent laboratory at 99.8% purity by RP-HPLC. This is that certificate; every box ships against a batch certificate you can pull by its number in the certificate lookup.

Each box of TR20 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 4814.5 for 1+, m/z 2407.8 for 2+, m/z 1605.5 for 3+, m/z 1204.4 for 4+, against a calculated average mass of 4813.5 (C225H348N48O68); the measured mass should agree to within a unit.
• Related substances. Any single related substance not more than 1.0 percent. On this sequence the ones to look for are light products of the tryptophan (kynurenine and hydroxytryptophan) and the deamidated chain, one mass unit up, from 2 glutamines.
• Main peak position. On C18 the main peak comes late in the gradient because of the C20 fatty diacid on lysine 20; the backbone’s Kyte-Doolittle average is -0.11 over 39 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.
