Peak O2 has short and long term benefits although long term benefits are way better. After about 2 weeks of taking 2 grams per day you have more strength and a lot more endurance since your body uses oxygen more efficiently.

you can defenetly feel the effect of this product! just drink it 20min before your workout sesh and you would not feel the hipoxia, especially if you are working out in a gym inside, where is very warm and o2 deficit.

Nice one, it helps me to be more efficient in study and training, helps deliver more oxygen to your cells. I use 1 scoop before training 3 times a week

The endurance you get from this thing is just great. All my friends love it. After a couple of weeks they can do much more in their workouts and feel less fatigue not just in the gym but throughout the day in general.

I thought this product might taste odd, but to my surprise it’s not bad. I did notice though that about 15 minutes after taking this product with water I had to go to the loo. I couldn’t really say if I noticed a big change in my work out performance.

Great supplement that improves the way your body uses oxygen. More power and endurance. Great for all athletes.

Great for recovery between sets and anaerobic endurance during my weight training

Simple ingredient list without anything added or extra. Great results with my cardio regimen.

It's a really good supps for endurance and perfomance!!!

Great product - helps with endurance during a workout. Need to replenish my stock as I'm almost through this bottle.
