Happy mixing
I have 20 years of experience calculating chemotherapy doses and was distracted and mixed 100 mg nic as if it were 24 mg.(while cooking,caring for a 3 year old and watching Oprah) .....DO NOT USE 100 MG e-liquid unless you are experienced and not distracted. This is embarrassing to admit but worth it to bring serious nature to attention of new DIYers. I caught the error as I always recheck each bottle like I did the meds. Check twice, calculate twice, place each ingredient aside together and recheck bottles after mixing. Good quality assurance= safety.
Happy SAFE mixing
Great OP...been following since start...thanks!
I too, was concerned about using 100mg nic. What I did was to mix up 24mg batches in 30ml amber glass dropper bottles. That way, I never have to directly use from the 100mg bottles.
I find that this method is safer and easier to work with as I always know that I'm starting with 24mg of nic.
BTW - I use amber (or any colored bottle will do) to slow down any degradation of the nic and then store the bottles in a dark case.
