Precum! Best lube so what's the composition?

I have always had an abundance of precum and whether solo or with a partner it was the best lubricant bar none. Yes, if I needed more, then commercial lubricants were used. But, precum is natural, tasteles and very slippery. One thing, perhaps someone here can answer for me. What is the chemical composition of precum? Can it be made artificially?

Your post had me curious so I Googled the chemical composition of precum.

This was what appeared. Too funny not to copy and past.

When someone with a penis is sexually excited, these glands churn out precum, which is a mix of components such as proteins, enzymes, and mucus. “Pre-ejaculate primes the urethra for sperm to come through,” Amin Herati, M.D., a urologist at John's Hopkins University, tells SELF.

For me, J Lube is the best but it does not taste as good as pre-cum. It comes in a powder form and I can mix is strong into a jelly like substance or weak as a watery substance.

I suspect its the mucus component that makes pre-cum slippery.
