Mocha 8 mg, I bought is at a Vap store here in Huntsville Al, but Im sure if you go online you can find it. It has a good tobacco taste and a good TH. I mix it with my 8mg menthol but I find it has a non menthol flavor
I could swear I read somewhere a while back when I got into DIY juices that adding everclear/grain alcohol can increase the TH.
This is a hard topic...call me crazy but me and my buddy have noticed that even the drip tips will give more of a throat hit than others. And one day my juice will give a good throat hit the whole day then the next day it does nothing. So i think so long as you always switch up the juice and don't give your throat time to get used to one flavor you should get good TH results.
nicotine does factor in a lot in the TH but the other thing that gives you that punch is the amount of PG. Higher PG maybe the reason your juice is low in nic but high in TH. Higher PG like 60pg or higher will give you more throat hit but the higher in PG you get less vapour. Its all what satisfies you and thats what vaping is all about. Funny how all of us differ so much. For me its all about the taste and clouds and clouds of vapour. TH is the least that I care about. I am a vape hound, I vape a lot( 3-9ml a day) so I have had to lower my nic content because I was over- nic-ing. I was getting nauseous and shaky and getting head aches. So I vape at 12mg or less, usually 6mg.
I was also remembering that some companies add certain flavors to their juice to get TH, ingredients like a touch of clove, coffee, cinnamon replicate TH. Your juice deliver also affects the heat and the TH. I get more TH with the same juice when I use my Phoenix RA and I think I remember that the Ikenvape 306 and the 901s 1.7 atty were too harsh for me so you might like them. You have to get and adapter for those to work with you 501 devices.
