I'm pretty skeptical. While l-arginine appears to be of some benefit in increasing blood circulation if taken orally, similar to the effect of pure crystalline niacin or of Viagra, a healing effect for peripheral neuropathy has NOT been demonstrated. Even if oral administration would be helpful, I couldn't find anything on the web that a solution of l-arginine, applied to the skin is of any help at all. L-arginine is an amino acid. I doubt that any would be absorbed through the skin.

Neuro-Eze Neuropathy Cream would provide some relief to the weight of your purse or wallet. It's available on the internet for $29.95 plus shipping for 75cc (about 50 doses, 25 if applied to both feet).
There are lot of charlatans out there wanting to take our money. At least l-arginine would be safe, though I can't vouch for its purity or other ingredients in the product.
You would save a lot of money and probably do more good soaking your feet a few times a day in warm Epsom salts solution. A bit of the magnesium sulphate would be absorbed through the skin, relaxing and calming the local nerves. That’s probably part of the reason the Rebuilder works better in an Epsom salts water bath as opposed to direct electro stimulation using contact pads.
