FormulaSignal is answering right now. Last checked 1 min ago. It exposes 18 tools.
Dated formula history, confirmed changes and evidence for U.S. pre-workout supplements.
Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 15 September 2026. No other catalogue keeps this.
A tool that vanishes takes a piece of your agent with it, and the change arrives silently. Watch this server and every such change lands in your inbox.
