I've put some serious time into figuring out that i can tolerate up to a 40% pg liquid. More than 40% and within I'll a few hours I have a sore throat and have what feels like a head cold. This will last for a few days then go away. Ok so halo offered me free samples. Great. So I ask, what's the pg/vg ratio? Their response...they can't release what their pg/vg ratios are! Seems its a secret. You gotta be kidding me. Check halo off that list of vendors for me to try.
