Summary of Customer Ratings & Reviews

Customer Ratings & Reviews

AjiPure L-Arginine (Pharmaceutical Grade) with Ornithine is rated 4.6 out of 5 by 16.
Rated 5 out of 5 by from Yes and no? I was using the Swanson Premium 500/250 combo for quite a while. They seemed to work as anticipated. The AjiPure went on sale, so I bought some. Did not really notice the difference, and, as someone else mentioned, for a "99-100% pure" product, they seem to contain a lot of other stuff. Not sure these are a great value. With 500/250, I have to pop 2 to get the full effect during a 2-3 hour workout. I ran out a while back and paid a fortune at GNC for some 1500/1000. They have a real bang, but seem to be over-priced and too high a dosage. I think 1000/500 is about right for workouts and ...other strenuous activities ;-)

Rated 5 out of 5 by from Big pills, small mg I've been using L-Arginine for training purposes for a while, but on and off. Started reading about Ornithine and wanted to give it a try. Only issue is, I don't get enough L-Arginine in one normal dose because they're 500mg instead of 1000mg... Not really sure the orthinine is making a difference either.

Rated 5 out of 5 by from correct ratio and combination of ingredients The Swanson L-Arginine combines with ornithine to make this a more complete amino acid complex. It is almost half the price of other combinations of these two amino acids. And there are not that many companies that combine these two close relately amino's. It is a tremendous value.

Rated 5 out of 5 by from Great product to boost natural growth hormone. Growth hormone production diminishes with age. Arginine/Ornithine help stimulate the brain to produce growth hormone during the first 90 minutes of sleep. I take this product before bed on an empty stomach to boost my growth hormone production which burns fat and builds muscle. I highly recommend this product!

Rated 2 out of 5 by from OK product otherwise. Would be great if this product came in an excipient free version. it may cost more and we would gladly pay to have the option of having supplements that only contained the substance we desire. OK product otherwise.

Rated 5 out of 5 by from Take the Long term View Like with any supplement there is almost no way to determine its total effectiveness. After googling and and reading, I feel this is a worth while addition to the my regiment. While I really do not feel different taking it I feel that there will be long term benefits from it so it is on my list! This form is suppose to have excellent absorption proprieties and I feel its a good value. Do your homework and if you wish this combo you see its on the money for price and potency.
