Prepare yourself for the most intense, the most muscle engorging and satisfying insane pumps possible! O2 positive by Biorhythm is not just any nitric oxide pre workout supplement it is the most savage and ultimate supplement if one of your main priorities is to feel pumped to the extreme!!!
The problem with other pre-workout drinks is that all though they may offer a decent pump during training this sensation of feeling huge usually fades shortly after training. With O2 positive's unique blend of compounds and patented time release formula, it literally re-cycles the nitrix oxide leaving you pumped several hours.
Using citruline malate, AAKG (arginine) as well as Biorhythms unique patented time release formula O2 positive is the ultimate NO2 supplement for those seeking the most long lasting pumps possible. By preventing the inhibition of nitrix oxide, O2 positive maintains elevated NO2 levels for hours enabling nitrix oxide to regenerate at increasing levels.
If you are sensitive to stimulants you will be happy to know that this is a non-stimulant formula, O2 positive is designed to give you the best possible workout possible without the use of compounds that can cause a jittery sensation.
