Let @janoshik know so he can quit the research. @BigNoOne already know that -ene impurities of Testosterone esters missing a proton on two adjacent carbon atoms in the gonane ring are properly resolved on his HPLC setup and not counted in the API peak. You could have saved him 200 USD on the reference standard he just purchased. He could use an analytical chemistry guru such as yourself.How are compounds tested for purity that go to the compounding pharmacies. Do the same.
It’s HPLC testing.
All "HPLC" is the same. Got it.
