- Needs 2 scoops for a real effect
Effects Timeline
AI-estimated changes in effects over the first 3 hours after taking the recommended serving.
The Curse! Stim-Free Pump leans toward pumps and performance, with no caffeine and nothing for focus in the formula at all.
At the standard single-scoop serving, most ingredients are dosed too low to do much — the label's own two-scoop option gets you a lot closer to a real effect.
Honest take: Underdosed and overpriced at the standard scoop — you'll need the full two scoops just to feel it.
