Hi Kellie and welcome to CT :smiley2: I use several different suppliers for fragrance oils, Peaks being one of them. IMO, Peaks oils seem stronger and more compatible with the wax that I use, which is the Golden Brands Wax. I try to keep variables to a minimum and don't use additives or color. Each individuals results will vary depending on the type of wax, fo, color, additives and wicks being used, heating/pouring temps, climate, etc... TEST, TEST, TEST until you find what works for best for you. Hang in there and have fun!
