I was wondering the same thing. I got 100mg of PG and VG from them. PG seems about right. but VG is giving me way too strong TH even after diluted into 16mg.
so I have run test that was on this forum. I am not sure how accurate my test result is. but result says my 100mg is actually 245mg...!
now I am wondering if they made mistake to dilute nicotine...?
