What You’ll Feel
Energy: 500mg total caffeine from a dual-source matrix (fast anhydrous + sustained Infinergy®) delivers relentless, long-lasting drive. Expect rapid onset followed by hours of controlled intensity — no sudden crash.
Focus: 4,000mg L-Tyrosine, 1,000mg CDP-Choline, and 200mg L-Theanine form one of the most potent nootropic stacks in any UK pre-workout. Tunnel-vision focus and elite mind-muscle connection from the very first set.
Pump: 10,000mg L-Citrulline with AmentoPump® and Himalayan salt delivers extreme, vascular pumps that last the entire session and beyond.
Endurance: 6,000mg Beta-Alanine — double the standard dose — drives serious lactic acid buffering so you can push further, harder, and longer every session.
Potential Effects to Expect
Rapid increase in energy and alertness, strong beta-alanine tingling sensation, enhanced tunnel focus and drive, and possible restlessness or disrupted sleep if taken too late in the day. This is a serious product for serious athletes.
How to Use Darkstims Ultra Pre
Mix 2 scoops (27g) with 400–600ml cold water and consume 20–30 minutes before training. New users: start with 1 scoop to assess tolerance before progressing. Do not exceed 1 serving (2 scoops) per 24 hours. Do not take within 6 hours of sleep.

If you need the strongest, most fully-dosed extreme high stim pre workout UK supplement stores carry — this is it. Available in Cherry and Red Apple, 500g per tub.
