Deads are where i notice the biggest gain as well.....and lower back is also what pumps the most painfully too. If you guys wanna try something fun......take some niacinamide b4 you go to the gym while on this stuff and work something that pumps up easily,like bi's .....it's absolutely crazy. Glad to see Bfold is trying it....outside of my mothers test results the 2 people i would be most anxious to see feedback from on it is B and Spatts.
