Does anybody have any additional information on this ingredient? I've been using TwinLabs Na-PCA spray for over 10 years but I believe it's been discontinued. I personally think it works great but it's more of an aging prevention product as opposed to a aging reversing product. I found a company that sells the ingredient so I can make my own spray. They recommend up to 4% usage but that seems so little. The concoction I've put together doesn't seem as potent as the Twinlabs spray. Is there any way to find out what percentage of Na-PCA they used?
Thanks in advance
