I've tested some of junyap's diy eliquids. Here's my opinion:
Cola - the best among all the liquids I've tried from junyap's diy. The cola taste is quite strong which is for me is good coz can really taste the cola.
Rum - flavor quite weak. Cannot really taste what it is.
Peach - strong taste. Really taste like peach. In my opinion, better than janty's peach eliquids.
Caramel - can't really distinguish the taste coz that time I vape cola before the caramel, and the cola flavor kinda covers the caramel flavor.
Coffee - really like coffee. But I'm not really a coffee fan. Very strong flavor. The coffee smell very strong also.
That's all of the flavors I've tried coz I've been vaping the cola constantly that time.
Overall it's quite good. Keep it up junyap bro. Looking forward to tasting some more new flavors on the next gathering.
I'd also want to request a flavor. I've wanted to try peanut butter eliquid. If you can diy bro, let me try. Thanks!
