Our verdict
GLP-2T Vial is the value pick. The molecule has 72-week data in more than 2,500 people and a head-to-head win over the first-generation compound, and the 40 mg vial works out to $4.13 per mg, the lowest in the catalog. It gives up a few points of average effect to the triple agonist in separate trials.
