Tested Athlete Performance Stack
Tested Athlete Performance Stack
Train clean. Recover hard. Compete with confidence.
The Tested Athlete Performance Stack combines Klean Pre-Workout, Klean Creatine, and Klean Isolate to support the three things serious athletes need most: clean energy, proven strength support, and fast post-workout recovery. Every product in this stack is NSF Certified for Sport®, giving you a cleaner path to performance with third-party testing for purity, label accuracy, and banned substances.
Why This Stack Works
Klean Pre-Workout supports focused training, endurance, and steady performance with TruBeet™ beet root extract, PurCaf® organic caffeine, and vitamin C. Each serving delivers 75 mg caffeine for smoother energy without the harsh overstimulated feel many athletes want to avoid.
Klean Creatine delivers pure creatine monohydrate to support strength, power output, repeated high-intensity effort, training volume, and lean mass goals. It gives athletes one of the most proven foundations in sports nutrition without extra fluff.
Klean Isolate provides 20 g whey protein isolate per scoop in a fast-digesting, low-carb, easy-mixing formula designed to support lean muscle, recovery, and post-workout repair.
Together, this stack helps support:
- Clean pre-workout energy and focus

FAQ
FAQ
The Tested Athlete Performance Stack is designed to cover three core performance needs without building an oversized supplement routine: pre-workout energy, strength and power support, and post-workout protein. Klean Pre-Workout supports focused training and endurance, Klean Creatine supports strength and repeated high-intensity performance, and Klean Isolate provides fast-digesting whey protein isolate for recovery and lean muscle support.
The stack includes Klean Pre-Workout, Klean Creatine, and Klean Isolate. Klean Pre-Workout provides 75 mg of caffeine along with TruBeet™ beet root extract and vitamin C. Klean Creatine provides pure creatine monohydrate. Klean Isolate delivers 20 grams of whey protein isolate per scoop. Each product has a clear job, so you are buying a coordinated performance system rather than three random supplements.
For athletes who may be subject to drug testing, knowing what is in a supplement matters just as much as knowing what it is supposed to do. Every product in this stack is NSF Certified for Sport®, which adds third-party testing for label accuracy, product quality, and substances prohibited in sport. No certification eliminates every responsibility for an athlete, but it gives athletes, parents, and coaches an important additional level of confidence when choosing supplements.
The stack is specifically built around products selected for athletes who care about third-party testing and cleaner performance support. That can make it especially relevant for competitive athletes and families who do not want to guess about supplement quality. However, athletes under 18 should use supplements only with appropriate parent, coach, healthcare, and organizational guidance, and every athlete should follow the rules of their school, team, league, or governing body.
Potentially. Klean Pre-Workout provides 75 mg of caffeine per serving, which is considerably more moderate than many high-stimulant pre-workouts. It is designed to support energy, focus, endurance, and training performance without making an extreme stimulant dose the centerpiece of the formula. Caffeine tolerance varies, so athletes should still consider their total daily caffeine intake and follow the label directions.
No. Creatine does not directly cause body-fat gain. It supports strength, power output, repeated high-intensity effort, and productive training volume. Some people may notice an increase in scale weight because creatine can increase water stored within muscle tissue. That is different from gaining body fat. For athletes, the bigger question is whether improved strength and training capacity support the demands of their sport and goals.
Maybe not—and that depends on whether you are consistently reaching your daily protein needs through food. Klean Isolate provides 20 grams of whey protein isolate per scoop, making it a convenient option after practice, lifting, games, or whenever a full protein-rich meal is not practical. The value is convenience and consistency. Protein powder should help fill a real nutrition gap, not replace quality meals unnecessarily.
You get the same three performance essentials in one coordinated bundle while saving money. Purchased separately, the current value is $144.99. The Tested Athlete Performance Stack is currently $130.49, saving you $14.50. More importantly, the products already cover distinct roles—pre-workout support, creatine, and recovery protein—so you do not have to guess which products belong together.
No supplement stack can replace the work. This stack is designed to support better training, strength and power development, adequate protein intake, and recovery. Your results still depend on structured training, enough calories and protein, hydration, sleep, recovery, and consistency. The reason to buy the stack is not because it promises shortcuts—it gives serious athletes well-chosen tools that support the work they are already putting in.
