tough question to answer, cuz everyone will obviously respond differently. The benefit you will get with getting either Pro or Final is the 4AD along with 1 test. 4 AD is better for bulking based on the idea that you will hold more water while using it (please correct me if im wrong). But I think that you will be very happy with either of BDCs products. I'm just over a week into my T1 Final cycle of 4 weeks and having nothing but praise so far.
I'll be posting before and after pics and stats after my cycle is over.
