So I bought dekang 24mg and liked it but it was a little to powerful for me so I would dilute it with VG to 18mg till I got some more. I ended up getting 18mg from another brand and the nicotine seems to not even compare to the dekang. I feel with the new stuff that's 18mgs gives me no nicotine feel. Are some companies, say, 18mg really equivalent to other brands idk lets say 12mg? Is that possible cause the new stuff really feel like there's no nicotine in them :/. Am I going to have to right a journal on what company does what! Oh if I buy from x seller use 24 mg if I buy from y seller use 36 mg? Seems unfair and confusing . Help please 
THANKS!
THANKS!
