The P.O1 Performance Shot has a shelf life of 24 months from the production date. The exact expiration date can be found on the packaging, typically printed on the bottom or side of the bottle.

For best results, store the shot in a cool, dry place, away from direct sunlight. While refrigeration is not required, consuming it chilled can enhance the experience.

Taking a P.O1 Performance Shot can be beneficial for enhancing performance, increasing alertness, and improving focus during training sessions or competitions. However, its suitability depends on your specific goal—in this case, maintaining a low heart rate.

What to Consider:

• Caffeine, a common ingredient in performance shots, temporarily increases heart rate by stimulating the sympathetic nervous system. Typically, caffeine doses between 3-6 mg/kg body weight elevate heart rate and blood pressure modestly during exercise (Astorino et al., 2012). However, habitual caffeine users often experience a lower increase due to tolerance.

• Other ingredients, like beta-alanine or L-citrulline, generally don’t raise heart rate significantly. Instead, they support performance through muscular endurance and improved blood flow (Trexler et al., 2015; Suzuki et al., 2016).

When a P.O1 Performance Shot Could Still Fit:

• If you’re used to caffeine: Regular caffeine consumers usually experience smaller increases in heart rate, making a performance shot manageable, especially during moderate-intensity exercise.

• Higher-intensity sessions: For workouts where performance and focus are priorities rather than strict heart-rate control (interval training, competitions, strength workouts), the benefits of a performance shot clearly outweigh minor heart-rate elevations.

• Dose and Timing: Using smaller doses or consuming your performance shot earlier (45-60 min before exercise) can reduce unwanted heart-rate spikes.

Realistic Recommendation:

• If strict control of your heart rate is essential (like zone-based aerobic sessions or specific endurance training phases), a caffeinated performance shot may slightly elevate your heart rate. In those cases, opt for stimulant-free alternatives.

• However, for most other training scenarios—especially higher-intensity or competitive efforts—the modest elevation in heart rate is typically manageable and outweighed by improved performance and focus provided by the P.O1 Performance Shot.
  

• In short, it’s about aligning your goals with how you use it: smart timing, appropriate dosage, and the right session type can make the P.O1 Performance Shot a beneficial addition to your regimen.

If you’re considering combining the Hyrox competition—a high-intensity functional fitness event—with the P.O1 Performance Shot, this could be an excellent pairing. Hyrox demands a combination of cardiovascular endurance, strength, and sustained mental focus, precisely the conditions under which a performance shot can make a real difference.
