Vaping off the shelf e-liquids for 7yrs now as a cigarette survivor. in a previous post I talked about how I was thinking I was going to have to quit vaping because any and all branded/off the shelf juices seem to be affecting my health (tight chest, coughing, nausea, etc every single time I vape) lately. First I would like to apologize to the amazingly kind people that posted in response to my last thread. I never replied to any of your very thoughtful suggestions because of the chaos in my personal life these last several months, but be assured! I read, appreciated, and took into consideration ALL of them and can't thank you enough. It really showed me how awesome and caring this community truly is. I just never got around to saying it at the time because I'm working with an android and still in the process of getting a good computer on top of all thats been going on with me. Thank you Now on to what I need help with desperately this time! I need suggestions on how to make my own DIY juice from home. I seem to be very very sensitive to certain flavorings, kinds/potency of nicotine, pg/vg brands and I want to make very low dose nicotine mixtures (like maybe 1/1.5mg) (I use 3mg now but want to go down in strength anyway) So.. 1. What is an excellent high quality nicotine concentrate i can get online? 2. What and where is an excellent high quality, tried and trusted site for concentrated flavorings? 3. What is an excellent high quality PG available online? 4. And same for VG And how do I make my own juice correctly? I'm assuming I will need bottles to mix in but what sizes do you think will be best for testing mixtures while I try to find the perfect blend? How do I not waste supplies too badly in the trial and error process? What is the best pg/vg ratio for diy? I need to get all of the necessary supplies ordered like NOW before I have to order another name brand bottle online and potentially suffer for another week with a $25 120ml name brand that I'm starting to suspect almost definitely has cheaper ingredients in its makeup that could for sure be the problem. I'm also concerned its vaping in general thats bothering me cause I'm just super sensitive (a common case in several aspects of my body/health) but I have to find out and making my own seems like a great way to really know what I'm vaping and figure out what exactly is hurting me. (Ps: had extensive allergy testing done for more than one reason recently and it turns out I'm not even slightly allergic to PG so thats ruled out. Was thinking that could be the culprit for a good while but nope.) My vape setup for years: 25mm Terk V2 RDA with dual fused claptons (2x26/36 full kanthal) 3mm @ .25ohm 75-85watt on an Aegis Legend. CB prime.
