QUESTIONS. ANSWERED.
What is Mr. HYDE® NIghtmare Dual-Tub?
One tub, two full-size formulas. Sweet Candy on one side, Sour Candy on the other. Run them separate or mix both scoops for a third flavor: Sweet & Sour Candy.
How is Mr. HYDE Nightmare different from other pre-workouts?
Nightmare is built on three systems — Perform, Energize, Replenish. L-Citrulline and Beta-Alanine support performance and blood flow, a 300mg triple-source caffeine matrix and Alpha GPC drive sustained energy and focus, and Himalayan Rock Salt replenishes electrolytes.† Fully disclosed. Clinically dosed. Nothing hidden.
Can I mix the flavors together?
Yes! Each side contains a different flavor, but you can also combine them for a third
option: Sweet & Sour Candy.
How much caffeine is in Mr. Hyde Nightmare?
300mg per full 2-scoop serving, from three caffeine sources for fast onset and sustained energy.
I’m feeling a tingling or warm sensation, is that normal?
Totally normal. That’s the beta-alanine at work, it helps with endurance and can cause a slight tingle that fades after a few
minutes.
Is Mr. Hyde® Nightmare suitable for everyday use?
Mr. Hyde Nightmare is a high-stim formula built for training days that demand maximum output — not an everyday staple. We recommend cycling use around your hardest sessions and giving your body regular breaks from stimulants.
When should I take Mr. Hyde® Nightmare?
Take it 20–30 minutes before training. Because of the 300mg caffeine dose, avoid taking it within 6 hours of bedtime so it doesn't compete with your recovery.
Can Mr. Hyde® Nightmare be used by beginners?
Mr. Hyde Nightmare runs hot — 300mg of caffeine per full serving. If you're new to pre-workout or sensitive to stimulants, start with half a scoop (one flavor side) to assess your tolerance before working up to a full 2-scoop serving.
Does Mr.Hyde® Nightmare contain any banned substances?
No, Mr. Hyde® Nightmare does not contain any banned substances. It undergoes rigorous testing through Informed Choice to ensure safety and compliance.
Does Mr. Hyde Nightmare contain creatine?
No. Nightmare is built around energy, focus, and hydration — not creatine. Want a full dose of creatine too? Stack it with Dr. JEKYLL®.
