4.0 out of 5 stars Great for Workout Endurance, May 15, 2009

I had originally bought a 10-packet box of a workout energy drink mix to try, not really knowing much about what was in it. Well, it seemed to work -- every time I drank the stuff before working out, I could easily get an extra 30 minutes in before I had to stop. So I looked at the contents, and among other things it contained 2500mg L-Arginine. After finishing the box and doing some research on L-Arginine, I searched around for a cheaper alternative source (the drink mix was almost $3 per single packet). This is where I landed, and I bought one of these 2-packs to try out. Doing the math in my head, the amount equivalent to the drink mix is about 30-35 cents, or less if you sign up for the auto-ship!!

I now take 3000mg about 30 minutes before I start working out, and I can feel a significant difference. Recovery time is much faster -- no matter how hard I work, once I stop to take a break I feel like I'm ready to start again in no more than a minute or two. I'm also there a lot longer, as I said earlier.

The only thing I'm not crazy about is the tablet itself. Personally, I prefer the capsule style, like the Vitamin Shoppe capsules. I think I might stick with those from now on (plus, they're 1250mg each instead of 1000mg). But that's not to say that these aren't great too. It's just a matter of preference for me.

5.0 out of 5 stars Does the job, October 15, 2010

I bought this to get my blood pressure down. I was in the 140's to 150's systolically speaking, and now, with no lifestyle change besides adding this supplement, I'm usually at about 124 over 74. That's not amazing, but it's pretty good, and I don't have to take Diovan anymore.

I expect to keep using this product indefinitely. It's an inexpensive way to help insure against having a stroke, aneurysm, or renal failure. And, yes, it's a big pill, but I haven't had any problem getting it down.

This stuff really gets the job done. I used to waste a lot of money on expensive nitric oxide pre-workout supplements. Look at the label on almost any of them and you will see the main ingredient is L-Arginine. I am using this to give me a boost for p90x. Did not notice much change for the first couple weeks, but since then there has been a noticeable improvement in endurance and muscle tone. I take 5 pills a day with gatorade for 4 weeks and then take 2 weeks off (mayo clinic website recommends 6 grams per day for four weeks to enhance athletic performance). I also have problems with circulation in my hands and feet and these pills have helped improve that as well. I have not experienced any bad side effects. Great value for the price
