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 leans hardest into performance, with beta-alanine and creatine both individually disclosed at real doses.
Pumps and focus are both fairly light, and two named ingredients could not be credited at all -- the ginseng extract uses a less-researched plant part at a dose far below anything tested, and the CaloriBurn GP ingredient has real evidence for thermogenic effects, not the pump or performance categories this formula is actually being scored on.
Like every other ProSupps product reviewed here, every "matrix" total checks out exactly with full individual disclosure -- no proprietary blend guesswork needed.
Best for: People who want a simple, caffeine-free performance formula and don't need strong pumps.
