Don't Take Arginine Pre-workout ?!?
I know a lot of people (including myself) like to take Arginine 'pre'-workout for the pumps, but it appears pre-workout oral Arginine may be counterproductive, as it may actually reduce the GH (growth hormone) response to exercise... some are suggesting that it should only be taken on off days or 'post'-workout...
(see "Oral arginine attenuates the growth hormone response to resistance exercise" - [url]http://forum.bodybuilding.com/showthread.php?t=1655191[/url])
However, I haven't found this discussed in the context of a full pre-WO supplement stack. I suspect that studying the performance of a pre-workout stack such as Creatine-Mono/Arginine/BCAA as a whole may be different than looking at the effects or Arg alone (since Arg is a Creatine precursor, etc.)
[b]Should we not be taking Arginine pre-workout... should we not take it at all???[/b] Can anyone provide any further technical insight? Scientific references? (no product info or sales pitches please).
Thanks...
