Product Description

This is the advanced stack. Built for athletes who've outgrown the basics.

Dr. Jekyll Nightmare delivers stim-free precision—clean focus, powerful pumps, and total control, with zero caffeine standing in the way. Mr. Hyde Nightmare delivers the opposite extreme—300mg of caffeine, relentless drive, and performance built for the athlete who trains through excessive physical and mental stress.

Neither one holds back. Together, neither one competes.

Jekyll's L-Citrulline and Betaine Anhydrous drive nutrient delivery and pumps. Hyde's electrolytes and nootropics keep you locked in through the crash points other pre-workouts can't touch. Stack them and you get full-spectrum coverage—precision and power, running at the same time, in the same session.

Control meets chaos. Nightmare meets Nightmare.

Fully disclosed formulas. Clinically dosed. Banned substance tested.

Run Jekyll alone for stim-free training days. Run Hyde alone when you need to dominate. Stack both when the session demands everything you've got.

This is what Master Both looks like at the highest level.
