Im new to vaping (6 months) but I got a bottle of 555 juice about 4 months ago. Best taste I had tried to date. Went through 3&5- not any where near as good. I decided to start mixing myself. I think I finally got it right. 3 ml-36 mg vg, 1.5 ml-36mg pg, 1.5 ml-Alvin ecigs 555 flavoring. So close I can't tell the difference.
