Great for Workout Endurance by Jeff Kraus (Orlando, FL USA)  4 Stars
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 (available on the pack when purchased from Amazon)!
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. Since they end up being nearly the same price when you buy the 300-count bottle, 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.

Does the job! by K. McAllister (Tehachapi, CA USA) 4 Stars
February 26, 2009
I take one of these before my workout, and definitely notice an increase in circulation. The effect lasts about 2 to 3 hours, which is plenty of time for my workout.
The pill itself is not coated, and is medium-large (not as big as TwinLab's Amino Fuel Mass) so if you're not accustomed to swallowing pretty big chalky supplements, they might be difficult for you.
The price is right, too--Amazon is much cheaper than the health food store on these sorts of supplements.

It does work! by Chris  5 Stars
February 12, 2009
I started using this product to enhance the benefits of workouts. I have been pleasantly surprised by other affects. After using the product for 4 months, my flacid penis length has increased from 4" to 4.5" and erect length from 6.5" to 7.20". It is easier to gain an erection. I can also last longer (over an hour on a second go round).

The Arginine Effect by Bronx 5 Stars
September 18, 2007
I was curious & skeptical about this product and if it would really have any noticeable effects with regard to male virility. I have read a lot of medical articles and done a good amount of internet research on this amino acid and everything I've read points to a positive result regarding sexual wellness when Arginine is used as a supplement. The standard dose of L-Arginine for erectile dysfunction is 5000MG (5G), so used that dosage for my own bio-assay results and sexual experimentation. I have taken daily 5000MG doses every morning for the past 4 weeks and have noticed a few things:
1. Semen level increased SIGNIFICANTLY upon reaching orgasm.
2. Orgasm lasts a bit longer. Probably because of the increased amount of semen.
3. Orgasm feels a bit more intense (sometimes very intense).
All in all, I would have to say that I definitely notice positive results when using this supplement for sexual wellness. I plan to keep using this supplement for extended study.
Please keep in mind that many "male enhancement products" (including Enzyte) contain the amino acid L-Arginine and falsely promote incredible results. These product claims are used as a gimmick and appear to be erroneous. My observations:
1. Arginine did not increase my libido or stamina.
2. Arginine did not increase the size of my penis.
3. Arginine did not produce a firmer or longer lasting erection.
Research of Arginine suggests the following to be true:
1. Increases sperm count and motility.
2. Improves erections.
3. Shows promise in the treatment of male infertility.
4. Preliminary evidence shows that Arginine could be helpful in men with erectile dysfunction.
