The Retatrutide 20mg listing, also referred to as Reta 20mg, supplies a single vial of lyophilised powder under the compound identifier LY3437943. The 20mg quantity is the labelled mass in that vial; it is not a concentration or an administration instruction.
This format differs from both the 10mg single vial and the Retatrutide Bundle Kit. The kit divides its listed Retatrutide quantity between two 10mg vials and includes a separate water vial. The 20mg product here contains one peptide vial only.
Choose a laboratory purchasing specification by comparing container count, labelled mass, current price and the documentation attached to the individual listing. A larger labelled mass does not establish a different purity result or equivalence between lots.

Yes. This listing is one vial labelled as 20mg of lyophilised Retatrutide, rather than two 10mg vials. It is supplied as dry laboratory material.
No. The bundle contains two separately packaged 10mg Retatrutide vials and a 3mL water vial. This listing contains one 20mg Retatrutide vial, with no separate diluent included.
Compare the labelled mass per vial, current price and the documentation on each page. A price per milligram is a purchasing comparison, not a measure of purity, a prepared concentration or evidence that two batches are identical.
Reta and R3TA are shorthand used for Retatrutide in peptide listings. RT3 may be used in the same context but is ambiguous, so confirm the full Retatrutide (LY3437943) identity and 20mg quantity. These short names do not change the supplied format: one dry vial, not a ready-made solution.
