You must have a good nose for nicotine, nicselect is pretty clean. However, CNT nic from liquidbarn is regarded as the best. CNT is so neutral and clean that's its almost hard to Vape unflavoured as I do. I tried some flavor in it, it was very good, it popped lol. Try CNT.
Based on
@Vapntime 's suggestion from another thread, I just received my CNT from Liquid Barn (100mg in 500mL PG).
Totally clear, odorless, tasteless as far as I can tell.
I mixed a 60mL bottle at 36mg to use in recipes - using 21.60mL nic and 38.40mL Liquid Barn PG.
Using e-liquid-recipes calculator with Max VG option, 6mg final strength, and total flavor at about 13%, final ratio comes out to be - PG/VG-ratio: 30/70 for 10-15mL recipes.
So far, I'm very pleased with the few recipes that I've tried.
