Because my dood its safe to test your nicotine from what I've read people get stronger stuff then what they pay for...
A few more questions if I may..
1)Is the percent of flavoring you put in your juice generally the same? Between 15%-20%?
2)what if I add vitamins? if you use vitamins how much do you add?
3) And my original question if anyone has ever tested their nicotine...Is there a limit to how many drops of bromothymol I should use? the video didn't give a definite answer and he wasn't testing 100mg nicotine.
Also for whatever its worth I appreciate the advice everyones giving me, its helped, thank you!
