Why Loading PeakO2 Matters

To maximize the benefits of PeakO2, your body requires a "loading phase." This is because the active compounds need to accumulate in your system to deliver peak performance benefits.

How to Load PeakO2:

Daily Dosage: To "load" PeakO2 effectively, take 4 grams daily for the first two weeks.

Why 4 Grams? This dosage ensures that PeakO2 saturates your system, enabling faster and more noticeable results.

When to Take It: You can take it all at once or split the dose. Mix it into your pre-workout, intra-workout, post-workout shake, or even in your morning coffee!

What Happens After Loading?

After the initial loading phase, you can switch to a maintenance dose of 1–2 grams daily to sustain the benefits. At this point, your performance levels will remain optimized, and your endurance will stay enhanced with consistent use.*

    Noticeable

    This is my first time using this supplement & I noticed changes immediately. Not only does it help with endurance, it tastes good.

    Endurance!!

    I was really looking for a non stim pre workout but their bloodshot was out so I went with this in hopes to carry me over until they restock. So far so good! I never taken pre workout or any other supplements not even protein. But I thought after 9 months of busting ass in the gym it was time to get to the next level. I’ve noticed quicker recovery between sets and I’ve been able to push out an extra set or two on later exercises. Basically, I don’t seem to be busting my load on the first couple of exercises any longer lol

    Great Product

    So for me personally I found this product to be highly effective at raising one’s energy level way above normal to perform hard workouts. I use this product on leg days or heavy lifting days. Word of caution for people who do not weigh much ( I am 157 pounds ) it does keep your heart rate up for a long time so I use only a quarter scoop with the scooper that was supplied in container.
