I found a few commercial juices that I like, but some have very low nic.  I am two months into non-smoking and require more nic.  At a vape shop, they sell 'nicotine packs' that are pre-measured 1ml or 2ml nicotine to add to commercial juice.  The price is high. 
I have found one or two online, but I have no idea if they are decent. I don't want to ruin my juice with bad nic. I went to nicotine river and other web sites, but have no idea what nicotine I should buy, so the nic packs seem safest.
Can anyone recommend good pre-measured nic packs?
