I have been making my own juice, almost as long as I have been vaping. I use 100 mg concentrate from both wizard labs, and NN. My latest purchases have been mainly NN, because they offer the Nude Armour, and I am hording! lol I have 500 ml of the Armour, and 500 ml of the plain 100 mg. Now browsing I found the nicotine salts concentrate, and I was interested because of the claim of even longer freezer life, more so than the "hit" aspect. Like always when I have a question, I come to ECF, but there doesn't seem to be very much info on the topic of NN nicotine salts, and if it is more stable, and stores longer, unless I am missing it. Links would be appreciated if I missed them, and opinions are solicited from anyone who has any knowledge on the subject. Thanks.
