Mr. Hyde Signature is a straightforward, no-frills formula — every ingredient is right there on the label, nothing hidden.
Performance and pumps are both solid at the standard single scoop, with focus the comparative weak point.
Stepping up to two scoops takes performance to an exceptional level and meaningfully improves everything else, at the cost of a genuinely high 400mg caffeine dose.
Honest take: Excellent value — real pumps and performance at one of the lowest prices here.
