:cough: scam :cough:

here's a supplement that works AND it's free! It's called 'breathing'. You inhale oxigen and exhale carbondioxide.

lol

fruits and vegetables help carry oxygen to the blood. so i dont know if it would be a TOTAL scam but likely not worth the money

I tried Oxydrene and that stuff is incredible! My stamina and strength was through the freaking roof and never ran out of breath or had to do deep breathing. Give it four days before you notice a definite improvement. Follow the directions to the letter and you WILL see results. No joke guys if any of you doubt deep tissue oxygenators I DARE YOU to try this one.
