I am 34, and have been out of shape since leaving the military seven years ago. I started using Testatropinol in September after about two months of no-supplement weight training, and noticed a slight increase in performance almost right away. Cycling on and off the product since then, I can say that my ability to pack on muscle weight has improved noticeably. My energy levels didn't really change much, but there was an increase in strength within a few weeks use. I prefer the pills to the liquid version of this product due to taste and ease of use, though my best customer-service experience with illpumpyouup.com came about due to ordering the liquid. One of the 2 bottles I ordered arrived broken, and a quick email to illpumpyouup.com had a free replacement bottle in the mail within days.
