❝ I guess you had also the same batch of the test? Was the AUC different as well?

Both the tests were different but Reference were same. AUC of Reference was similar for both the studies, only Cmax varied by 22%. What may be the reasons for this?

❝

❝ If long term storage was validated for this duration, no.

Ok. Thanks
