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.*

    Peak O2 Review

    5 stars, I've been using Peak O2 on my ride (cycling) days in my water bottle when I'm doing endurance rides, its definitely made a difference to performance compared to when I wasn't using it. Usage with Citrulline, and Beta-Alanine.

    Solid Functional Mushroom Sup

    If you are into functional mushrooms, this product is for you. I added this to my no-stim stack, which also contains beta alanine, creatine, and citrulline for my pre. I feel it adds a little boost.

    The most prominent effect of this is actually mood for me. I feel way less of a baseline stress level and I am a bit more relaxed I find. I also have a pretty mentally demanding job, and I feel a little more mental stamina.

    Overall I like it a lot.

    Noticeable

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