How was the Test boost on the 550? I'm 39 turning 40 soon, and libido has been slowly diminishing over the past couple of years. Really don't want to deal with bumps or zits at this age, if it's back bumps I can deal, but not the moneymaker. I've heard ABE makes u quick tempered too, no time in my life for much of that.
Rise and Swell by mind and muscle has many people on the forum swearing by its test boosting properties. It's worth checking out and it's super cheap!
