Vitamin c? Lol .. I just made some injectable vitamin C, And that stuff is even more acidic than glutathione, I did some reading about it and I was able to get the pH up to 6, but it wasn't easy, way harder than glutathione, I actually passed it the first time and it all turned orange or brown I'm not sure which I'm color blind, but I oxidized it and destroyed it immediately. I got it down the second time, but you'll never raise the pH of anything with that stuff, It's acidic as hell. I also made Sampei's new recipe, but I used 12 g instead of 18 g, so it's 400mg instead of 600mg, I'm not sure why I guess I had a moment, lol It dawned on me as I was filtering it.
