Yes, atleast that been my experience. Even on a shity diet I noticed a dramatic change. Thats what I like about Tren is that (I shouldn't be saying this but its true) your diet doenst have to be as strict, its so effective that it will still cut you up, give a little size, alot of strenght and a chizzled look depending on your existing physique.
I'm sure some will disagree but thats been my experience.
