I’m extremely new to diy vape juice and I have only been making recipes for a couple days now but all of the mixes I have made wether it uses regular nic or salt nic I don’t really get any nicotine from any of the mixes. With store bought juice I drip 3mg on my box with an rda and that was enough and I would still feel the nicotine at the back of my throat every hit. The first mix I made was at 3mg and it just didn’t feel right. It felt like I was at 0mg then I bumped it up to 6mg still nothing and then I tried 9mg still nothing so I assume that my nicotine has gone bad. Any help would be great I’m probably just overthinking it.
