The liquid volume of the injection was also cut in half. This is because the anti-aggregation excipient hydroxypropyl betadex (a form of cyclodextrin) not only extends the time Tesa can be reconstituted without aggregating, it also prevents the aggregation that occurs when peptide concentrations are too high.
"The old formulation contains histidine, mannitol, polysorbate 20 and sucrose as excipients, whereas the “super-originator” product comprises hydrochloric acid, hydroxypropyl betadex (HPBCD), mannitol and sodium hydroxide"
"The new formulation, EGRIFTA WR, is set to replace EGRIFTA SV®, well exemplifying how a cyclodextrin can enhance the life-cycle of a valuable active pharmaceutical ingredient."

Unfortunately in this scene very few vendors ever disclose the excipients in their peptides, and most users think the volume they choose to reconstitute peptides with doesn't matter.
