From their website:
Our ingredients contain USP Grade Propylene Glycol and USP Grade Glycerin along with a proprietary blend of USP Grade Natural and Artificial flavorings. All ingredients are FDA and FEMA approved food additives, and we use only the highest quality USP Grade Nicotine with a Certificate of Analysis. Our nicotine is tested and documented to be a minimum of 99% pure before our e-liquid is created in our US facility.
So they do use VG but their ratios are proprietary.
Thanks for that clarification..... I did see it said Glycerin but I did not put 2 and 2 together that it was VG ..... my bad still if I had to guess it is a smaller ratio of VG to PG hence the light viscosity of Halo juices..... Personally I can not only taste in a good way the difference but actually feel the difference.. Personally I think Halo is the standard for all others but, that is my humble opinion. Another good juice I have been tooting lately and I have never heard of them before is a brand called Qualit E Juice... I have been vaping their honeywood tobacco and at first I didn't like it but after a week and a half of steeping it is much much better. Not Halo good but good none the less and I can get it at my B&M and support them a bit a well.
