Although some testimonials complained about the orange flavor, almost all report a big increase in lean mass of the arms using their normal workout routine about 30 minutes after taking the product. These testimonials seem to be in step with the manufacturer's claims. Other testimonials report an overall gain in size and strength as well as more noticeable pumps and increased energy.
Two important things that users pointed out were (1) don't take the stuff within four hours of bedtime and (2) don't take any additional stimulants while taking SuperPump 250. Also, they said that your water intake will rise substantially, many users reporting that a gallon a day was pretty normal.
While the benefits of SuperPump 250 need to be evaluated by the individual bodybuilder based upon his or her specific goals, SuperPump 250 does appear to be worth checking out in your effort to gain muscle.
