Why
The Ultimate Performance Stack combines three high-impact formulas to create a unified system for explosive energy, muscular endurance, and rapid recovery. This is not just a “stim bomb” combo — it’s a purpose-driven stack that allows you to train hard, recover fast, and return stronger each time. Doomsday delivers clean, potent energy and focus, perfect for athletes tired of jitter-heavy pre-workouts that kill appetite or ruin sleep. One More Rep, the evolved version of BPI’s iconic 1MR, backs this up with science-backed ingredients to increase muscular endurance and vascularity — ideal for pump lovers and volume trainers. Best BCAA Pump rounds it all out, offering intra-workout hydration, muscle recovery, and pump-enhancing ingredients like MCTs and hesperidin. Together, these three products cover every stage of training — from pre-session energy and focus, to intra-workout endurance and hydration, to post-workout muscle support and repair.
When
Use Doomsday and One More Rep together 20–30 minutes before your workout for a synergistic blend of clean energy and nitric oxide-boosting performance. Best BCAA Pump can be taken intra-workout to maintain hydration and pump or used post-workout for faster recovery. On non-training days, it can also be used between meals to prevent muscle breakdown and stay anabolic.
Who
This stack is ideal for intermediate to advanced athletes who are serious about performance. Whether you’re pushing for strength, hypertrophy, or endurance, it supports every angle of training. Suitable for men and women, it’s best for users who want sustainable energy, solid focus, vascularity, and muscle recovery without excessive stimulation. Ideal for those who want full-phase workout support without feeling “wired” or crashing later in the day.

Directions
Doomsday - Shake the product before use and mix 1 scoop with 250ml of water 20 minutes before exercise, ideally on an empty stomach. BCAA Pump - Mix one scoop (10.4g) with 250-300ml of water and consume before, during, or after training for optimal muscle recovery and hydration. Suitable for daily use. One More Rep - Take one (1) serving (1 scoop) approximately 15-30 minutes prior to training, blended with 200-250ml of cold water or beverage, or as suggested by a qualified healthcare practitioner. Do not exceed 1 serving per training day. Avoid eating food or drinking a protein shake within an hour after consuming ONE MORE REP. To avoid sleeplessness, do not take within four (4) hours of bedtime. Taking ONE MORE REP with food, or on full stomach, may diminish its effects.
