Dr. Jekyll Signature (V2) Review
- Caffeine-free, take it any time
- Solid performance support
- Fully disclosed, no proprietary blends
- Pumps are a real weak point
- Ginseng dosed far below any tested amount
- One ingredient has no relevant evidence here
Effects Timeline
AI-estimated changes in effects over the first 3 hours after taking the recommended serving.
Dr. Jekyll Signature is built mainly for strength and performance, with real, solid doses of beta-alanine and creatine doing the heavy lifting.
Don't expect much of a pump or a focus boost here — both are light.
Two of the label ingredients, a ginseng extract and CaloriBurn GP, are dosed too low to expect anything from them.
Honest take: A narrow, one-dimensional formula that doesn't justify choosing it over stronger options at a similar price.
