Great Formula!

Posted by Reviewer2009889 on Mar 11, 2011 | Verified Purchase

I have used Jarrow for several years and this product has been my favorite. I can feel a difference within 30 minutes. I workout regularly and feel this formula has been a big help to my stamina.

Thanks for your feedback!

I have taking this for a week or so, 2 tablets at bedtime with no side effects like headaches though in general I get them easily. This arginine + ornithine gives me nice dreams too as surely it does relax my muscles. During the day I have been also taking Arginine tablets 2 times1 gram for 20 days now and still take them, also from Jarrow. I am under the impression that since I have started these 2 supplements my muscles can take more day after day endurance wise. I-herb is seriously a great company, good packaging, fresh products and fast delivery even for Europe. While Jarrow produces great stuff.

Excellent brand and excellent quality, but the best part is, it's much cheaper than all those NoS concoctions the bodybuilding supplement companies try to sell you. Throw back a couple of these before working out and you will get that pump you are seeking.

The "burning" pill

I have a iron gut, but whenever I take this pill(after meals, of course) it irritates my stomach.
