Ordering at volume

Requests for this line arrive under three names, retatrutide, RETA and DP3-R, and a purchase order that uses one while the quote uses another invites a query on a first order. Whatever name the buyer uses, the quote restates the catalog name, the fill weight and the SKU code, and the carton label carries that same code. Confirm the three agree before the order is released; it is a two-minute check that removes the one ambiguity this line has.

Retatrutide is held as a high-volume staple, so a typical order is filled from stock rather than from a synthesis run, and a confirmed order ships within days of the written quote. Where a quantity can be met from stock on one fill weight sooner than on another, the quote says so, and a buyer who can accept 30 mg vials in place of 60 mg, or the other way round, keeps the shorter date.

Per-vial rates on the three fills scale with the peptide mass in the vial, as they do for any lipidated peptide of this length, and each fill is quoted as its own line against the breaks at 1,000 and 2,500 vials. Retatrutide vials do not pool with tirzepatide or semaglutide vials toward a break; an incretin order spread over three compounds is three separate ladders. Per-vial figures are being confirmed against the current sheet, and the written quote governs until they are; the pricing page explains the ladder.

What the material is

Retatrutide is a synthetic peptide built as one continuous chain on a glucagon-family backbone. It belongs with tirzepatide and semaglutide in the group of long, modified peptides this catalog files under the incretin family, rather than with the short unmodified sequences elsewhere in the list. The residue count and the exact set of substitutions are not stated on this page because they have not been confirmed against our own documentation; the certificate for a given lot records what was tested and found.

The chain is lipidated: it carries a fatty acid-derived side chain. That lipid group is why the material behaves like the other acylated peptides here in the vial and in solution, wetting slowly and foaming when shaken, and it is the feature a buyer moving from a short peptide to this one will notice first.

It arrives as a lyophilized powder or cake, white to off-white, under a stoppered and crimped seal, at 10, 30 or 60 mg of peptide per vial. The vial contains dry solid and nothing else. The cake should sit as one porous piece; a cake that has shrunk, cracked into a glassy layer or left a ring on the glass has seen moisture or heat.

Storage and reconstitution

Sealed vials keep best at −20 °C, in the dark and away from moisture, and refrigeration is fine for short holding. The solid tolerates the ambient excursions of a courier journey; what it does not tolerate is a breached seal, so any vial with a lifted crimp or a stopper that has moved should be set aside and reported rather than used.

Lipidated peptides of this size go into sterile water or a neutral aqueous buffer slowly, and with foaming if shaken, so the vial is left to stand and then swirled; the finished solution should be clear. Persistent haze means the peptide has aggregated, and aggregated material does not redissolve on warming.

Once dissolved, keep the solution refrigerated and dark and use it promptly. Freezing a solution is possible, but each freeze-thaw event loses some material to aggregation, so divide before freezing and thaw each portion once.
