synthetic is made to be "bio-identical"...
so in other words, bio-identical used in the sense you are describing, is more of a marketing statement used to make people who dont know any better, think that a "bio-identical" is more natural some how, which is not true.
I guess I am a little confused.... So let me ask this. Is Testosterone Cypionate or Testosterone Enanthate Bio-identical or man made? Or can they be both?
