Today marks Bodybuilding.com’s 15th year in the business, so like every other year they are celebrating with a massive sale. To fit in with the decade and a half birthday bash, the online retailer are offering 15% off more than 100 of their top brands for one day only. Some of the big names on the list include Cellucor, Muscle Pharm, Optimum Nutrition, Muscletech, and Dymatize. Another one taking part in the celebration is BSN, a brand that have actually gone one step further and produced a limited edition shaker with Bodybuilding.com. Which is in fact being given away with every order placed today, while stocks last. There is no coupon code required, just be sure to get in before the countdown timer hits zero at the end of today, and purchase something from one of the brands on the store’s 100+ list of names.
