Jelqing Lube

I got a lube to use for when Jelqing. I got the Palmers cocoa butter with vitamin e,I really like it, making the skin smooth and soft and lasts pretty long. I was wondering if there was anything I could mix in to make a better lube for Jelqing and improve the process of PE? I will try water i’m assuming would work but any other ingredients that would work to improve blood flow. and just benefit Penis.
