Just made this up. I liked all ingredients so I made 120 ml. Normally a new recipe I will make 30 ml if I've I liked the ingredients and 10 ml if newer flavors. I vape about 5 ml and it is great. In 3 days I bet I like it even more when banana settles and everything comes together. Low flavor %'s make it so it's not over bearing and easily an adv. Thanks!
