As answered by people managing StackRates and FormulaSignal.
FormulaSignal's answer:
FormulaSignal keeps dated copies of supplement labels published by brands and compares declared amounts line by line, so you can see when a formula quietly changed. It tracks 1,249 products from 152 brands (and growing), and every check is shown, failed ones included.
FormulaSignal's answer:
Lab-testing and review sites tell you what a product contained when they tested or reviewed it. FormulaSignal watches the label over time and emails you when a confirmed change hits a product you take, so you know before you reorder. The Locker is free for 3 supplements.
FormulaSignal's answer:
People who take supplements regularly, like pre-workout, protein, fish oil and multivitamins, and want to know if the formula they rely on has changed before they buy again.
