"It hasn't hurt me, but I can't really say it has helped, either. I was hoping to get something with a little HGH punch to it, but this has fallen short of my expectations. Probably won't buy it again."
"I was using L-arginine in powder form mixed with water...gross and bitter. I like the capsule because I know that I am getting all I pay for. I don't really trust a compressed tablet. L-Arginine mixed with Pycnogenol seems to be helping out fairly well."
"I bought this L-arginine during a BOGO sale. I usually purchase NOW brand - a 250 capsule bottle, because I get the best price for it but this was less expensive and I notice no difference than the NOW brand. I'm pleased."
"I switched from 1000mg once daily because the doctor that recommended L-Arginine for me said our bodies can utilize only about half that amount at one time. Splitting the dose into two makes for less waste and a more prolonged availability of the amino acid. Makes sense to me! Of course, I have no idea whether or not this product "works," but I have been pleased with the cost and simplicity of the Vitacost brand. I trust that their products are tested and verified, and so will continue to use them unless I find out otherwise."
