Does Defy use compounded test from different compounding pharmacies or pharmaceutical grade test? Also, what is the difference? I have the option of getting pharmaceutical name brand test from a local md who is A4M certified and specializes in hormonal replacement. There are also several local anti aging clinics that use compounded test from a compounding pharmacy. My questions are: What does Defy use? Is there a better choice or difference between pharmaceutical grade and compounded testosterone?
