AI analysis
Pulse Stim-Free delivers real performance support without any caffeine, but energy and mental focus both drop out almost entirely without it — a good reminder of how much of the original Pulse's strength comes from its stimulants.
This is Legion's caffeine-free version of their much stronger, caffeinated flagship.
Honest take: A pale shadow of the caffeinated Pulse, hard to justify the price for what's left without the stimulants.
