according to the research that ive read that best time to take arginine or citrulline is before bed
DO NOT TAKE ARGANINE WITHIN 4 HOURS OF YOUR TRAINING!
Use it before bed! (Not NO's with astimulants though!)
L-Arganine (the main constituent of your NO) supresses the growth hormone spike you should get from just good hard training!
That is the latest real research on it. No BS.
Effect on Growth hormones of pre or post workout arganine:
Just training Gives the highest
Just arganine gives the next highest
Arganine + training gives the lowest
Apparently the body has a feedback loop so it will take only 1 GH spiking event and the next event causes a negative feedback.
Training alone causes the highest spike!
L-Arganine before bed will give you all the NO benefits you want for the next day+
Most NOs on the market are really too low in dose (4-6 grams L-Arganine) to obtain the proper training effect, they are mostly stimulants (caffeine) and really, that is not what you want when bulking! Even though it feels good, it is counter productive for optimal growth!
Save the stims for the cutting when you will really want them!
