Previously GNC only had two sizes of BPI’s isolate protein ISO HD, a 1.6lb and 4.9lb. It didn’t have a trial or sample size like Bodybuilding.com, however this week that has all changed. BPI fans can now grab a 10 sachet ISO HD box from GNC for a lot less than either of the tubs. The cost of the convenient solution is $29.99 or $25.99 for Gold Card members, with three flavors to choose from in Vanilla Cookie, Banana Cream Pie, and Chocolate Brownie. The 10 sachet ISO HD obviously isn’t as cost-effective as the 1.6 or 4.9lb, but it does give GNC shoppers a chance to purchase something smaller before investing in either of the tubs.
