yeah, this can be done easily by everyone who has once been in good shape, esp with gear.
the guy has a very good media pr guy behind him, was featured from usa to uk to mainland europe in many newspapers from the getgo.
and now he has a book to sell.
Easy to fool the masses, and then he can make a few bucks out of it, might as well enjoy it.
I bet he even stayed on most of the time, so that he puts on fat but keeps his muscle mass. Then go on a cycle of tren, hgh, eca, cardio and a good diet and you'll be in shape in a matter of weeks.
Now fatty thinks he can do it too and buys your book, but it will not work for him.
