Clinically validated energy that delivers when it matters most – during your workout.
In sports nutrition, timing is everything. Pre-workout carbs and post-workout protein get plenty of attention, but what about during your workout? As athletes demand more from their bodies, intra-workout supplementation has become essential for maximizing performance in real time.
That’s where PEAK ATP® delivers.
PEAK ATP® is TSI Group’s patented form of Adenosine 5-Triphosphate (ATP) – your body’s primary energy currency. Unlike many ingredients that require a loading phase, PEAK ATP® works immediately with a single 400 mg dose, supplying functional cellular energy exactly when your muscles need it most.
Intra-Workout Support That Goes Beyond the Basics
During exercise, muscles require more oxygen and energy – while blood flow is redirected away from the gut. That makes fast-absorbing, GI-friendly nutrients critical for real-time performance.
Traditional intra-workout formulas often include carbs, electrolytes, and amino acids. PEAK ATP® takes it further, offering direct support for muscle ATP levels, which helps:
- Increase blood flow
- Enhance muscle endurance
- Improve recovery
- Reduce fatigue during exercise

What the Science Says: Clinically Proven Benefits
A single dose of PEAK ATP® has been shown to:
- Increase total work output by 24%¹
- Boost repetitions during resistance training¹
- Improve blood flow and oxygen delivery²
- Delay muscle fatigue and enhance endurance³
- Support post-exercise recovery and heart rate variability⁴
And with long-term use, the results are even more impressive:
- 147% increase in strength⁵
- 100% increase in lean body mass⁵
- 30% increase in vertical jump power⁵
- Better cognitive function post-exercise⁶

Formulation-Ready. Consumer-Approved.
PEAK ATP® is low-dose (400 mg), requires no loading phase, and delivers dual physical and mental performance benefits – making it an ideal addition to any intra-workout formula.
Whether you’re targeting elite athletes, gym-goers, or weekend warriors, PEAK ATP® gives your product a proven edge where it counts most: during the workout.
