The Story Behind 3RDphix
3RDphix was created to solve a problem most shaker bottles ignore — protein and supplements sticking to the bottom, creating clumps, waste, and frustration for daily users. Rather than adding more parts or gimmicks, we redesigned the bottle itself. The result is a patented round-shaped design that mixes more completely, with less effort and less waste. Built for daily use and designed to last, The Round Base Shaker 2.0 is made to replace disposable bottles over the long term — without compromising performance, durability, or simplicity.
