The smartest thing to do is drop the tren before he gets real shut down and has to milk himself..
Tren will make you lactate if you don't know what your doing and the lactation does not go away unless you get more drugs to correct it which is not what he wants.. And it has one of the harshest shut downs of any of the steroids you could pick and a lot of guys hop on it and never fully recover their natty test or have to go to TRT..
When you say he has no business.. Is he out of shape? to young? both? I believe you when you say he has no business im just curious.
