Simply not total true. Let's talk specifics. Taking dbol and testE with or without a severe increase of calories will bloat you and put weigh on you and if nothing else the scale is going to move and you are going to move a heavier bar.
If we are talking literal terms of "no gain" then what your stating is wrong but if you were simply talking in terms of "worth" then you are definitely correct. Without a caloric surplus his gains will not be nearly as great, no where close. But definitely beyond "no gain".
As far as the dhea is concerned, can we quit with the bashing of people whom have no results from a supplement. This has always happened since I can remember. If a person has no results from the supplement, okay, they just didnt. It gives no reason for bashing or discredit.
