Whether or not you are a fan of shopping at GNC. You have to admit the retail giant do a great job at luring in those who may sometimes shop at more competitive stockists. GNC do tend to actually get a helping hand in this department, with their long list of exclusive or special edition products. The latest of which comes by way of Top Secret Nutrition with a set of 20% extra tubs of the brand’s pre-workout Pump Igniter. In most places the supplement is available in three sizes, 8, 14 and 30 servings, with the GNC exclusive going six more than the largest with 36. The Top Secret formula has of course been kept the same, and given a value of $46.99, or $37.99 with a Gold Card. Aside from the slightly higher cost per serving, the only other catch with GNC’s exclusive Pump Igniters are the flavors. As fans of Top Secret’s recent additions pink lemonade and fruit punch, will have to settle for the original selection of red raspberry, cherry limeade and grape.
