Could someone please give me a simple formula (Drops please) to make a 5ml bottle of carmel(20% flavor) 50/50 at 15% so I can compare with mine. My base is 1000 ml 48 mg (4.8% nic mixed with 100% pg) and flavor is PG from PA. What i mix tastes like crap and not sure if I'm using the calc. right. Using juice me up. Thanx in advance! Getting very frustrated and need a pro to help. -Nate
