He just told me that ALL enzymes are bi-directional. Crazy, since the "bro lore" is that there are one way enzymes. How funny, he commonly schools me on "bro-lore" topics and I just have to laugh since all of the "respected" experts seem to think that they know so much. He said "this is basic textbook biochemistry that all enzymes are bi-directional"
So, if you take aromatase and put a bunch of estrogen in with it, some will back convert to testosterone! Weird since the common belief is that is not the case. Who knew!
He has a PHD in micro-biology with a specialization in Microbial Physiology. Pretty interesting guy!
