How pHastr Took My VO2 from 52 to 78 — And Why I’ll Never Play Without It Again

My dad has worked in high-performance sports nutrition for years. When he started formulating pHastr, I’ll admit — I was skeptical.

I’ve played for the Toronto FC Academy for 7 years, then transitioned to D1 soccer. I’ve used creatine, beetroot, and hydration powders.
But nothing ever made me feel noticeably different on the pitch.

Then I tried pHastr.
After a trial V02-MAX Toronto, my VO2 max went from 52 to 78 in a week.

The Protocol That Changed the Game
Here’s exactly what I did:

I took 7 capsules 3 hours before the test

Then 6 more capsules 2 hours before

I ate a banana and some crackers with the doses to help absorption

That’s 13 enteric-coated sodium bicarbonate capsules — the pHastr formula designed to buffer lactic acid without gut issues or bloat.

This follows the 0.2–0.3g/kg research-backed dosing model used in most VO₂ and buffering studies.

Before without pHastr: VO₂ Max = 52

After with pHastr: VO₂ Max = 78

Peak Test: Touched 82

What changed wasn’t just the number — it was how I felt during training and in games:

I didn’t fade after 70 minutes
I was still sprinting at minute 90+
No soreness the next morning
My legs recovered faster between sessions

 What It Felt Like On the Field
The difference was night and day.

Normally, I feel my legs slow down late-game. With pHastr, I felt light, explosive, and mentally sharp deep into the match.

I could recover faster between sprints. I didn’t gas out. And I stopped feeling sore the day after high-intensity games.

After seeing the numbers and feeling the difference in-game?

I’m never training, playing, or recovering without it again.
