Neighbours ask
Is FormulaSignal free?
Yes. The Locker holds up to 24 products free, with no card. Signal Pro monitoring is optional; plans are on the Pricing page.
Does FormulaSignal lab-test supplements?
No. It records what a brand declares on its label and product page, with the date and the source. A label is not proof of what is in your container.
How do you know a formula changed?
A changed page is only a lead. A change is confirmed when two comparable dated sources show different declared values and the finding passes review.
Which supplements do you cover?
Coverage is U.S. pre-workouts, electrolyte and hydration products, creatine products, and protein products, plus some adjacent products. Anything else can be requested free, with no promised date.
Can a brand pay to change what you publish?
No. Paying brands get no better treatment, no earlier notice of a finding and no right to review it first. Product pages link to the product's own Amazon listing where one exists, and FormulaSignal earns from qualifying purchases. Every product is treated the same way, and nothing that ranks or compares can read those links.
