Questions about MK-0773 testing

Can MK-0773 be confused with finasteride or dutasteride?

Not in testing. All three are 4-azasteroids, but they differ in mass and separate by HPLC.

What does the purity result include?

The main peak's share of the total peak area by HPLC-UV. Related compounds above the reporting limit show as separate peaks, and LC-MS can identify them on request.
