Seems to me that all Endorox is, is L Glutamine !

I like Gaspari Nutritions Super Pump 250,
http://www.supplements101.com/SuperP...perpump250.htm it has about 1g of Creatine per serving, an energy blend (caffine, ginsing etc), with a huge amount of Magnesium for latic acid! I find it gives great energy pre ride, and explosive energy for sprinting... all while getting you very vascular and pumped! just my .02$
I tried it last week pre ride, rode about 40miles @ 18mph avg., my legs were PUMPED, and I saw veins in my quads ive never seen b4.
by the way great forum! Nice to be here.
