Watch-outs

- You're sensitive to a high combined stimulant load, or want fully disclosed exact dosing
Effects Timeline
AI-estimated changes in effects over the first 3 hours after taking the recommended serving.
AI analysis
A real three-way stimulant stack -- 300mg caffeine paired with a conservative estimate of Dynamine and TeaCrine. Dynamine's fast onset and TeaCrine's longer duration are designed to smooth out caffeine's typical spike-and-crash, though exact amounts aren't disclosed on the can.
