OK, so I have to ask. Is this real, or is this a joke?

It may be good for the system but probably not.
But to inform OP, those who think it is are paying $880,739.32 per US gallon and the supplier is laughing his guts up.

No end of fools.  There's a dozen born every half minute.

Ho hum.

Since we're on the subject, can anyone offer their experience with Mad Scientists Audio Graphene contact enhancer.

So, I’m not all the way a believer…but can definitely appreciate the potential for benefit. Now…is there any other type of product that can still at least/almost meet the benefits of this product half-way at about 1/8 the cost? Or even less? Hopefully without detrimental side effects to connectors and contact points. 
Forgive the question…I realize this is (already) a well-beaten path 🙏🏼

This stuff is  GREAT go back to bed.

Thanks, Early Bowel Movement. That really helped. Jump on that ASAP!
