Two formulas. Zero overlap. One complete performance system.

Dr. Jekyll Signature brings the control—stim-free strength, endurance, and pumps that lock you in without a single milligram of caffeine. Mr. Hyde Signature brings the chaos—doubled-down energy, razor-sharp focus, and hydration built for the long haul.

Alone, they're both a full workout's worth of results. Together, they're something else entirely.

Run Jekyll's Beta-Alanine and Creatine underneath Hyde's energy and you're not just fueling intensity—you're fueling intensity that lasts. Jekyll's Choline and L-Tyrosine keep your mind locked in exactly where Hyde's focus peaks. Nothing fights for the same job. Everything stacks.

Precision. Power. Both, at the same time.

Beta-Alanine for endurance. Creatine for power. nooLVL for pumps. 2X actives for energy. Built-in hydration. Banned substance tested.

This is what happens when control meets chaos and neither backs down.

Master both. Stack the Signature Series.

Emma ★★★★★

The stim-free Jekyll formula is a game-changer for evening training sessions—I get the pumps without lying awake at three in the morning. Stacked together, they cover everything I need in one go, and the zero-overlap setup means no wasted scoops.

Hannah ★★★★★

I was skeptical about a stim-free pre-workout, but the endurance I get from the Dr. Jekyll side is legit—I’m hitting extra reps without any jitters. The two formulas stack cleanly, so I never feel like I’m double-dosing on anything.

Isabella M. ★★★★★

The pump from Dr. Jekyll keeps my arms feeling full through the whole session, and I like that it’s stim-free so I can stack it without jitters. The two-in-one system covers everything I need in one go.
