Thank you for all, guys, especially Susan~S, you help me a lot !
Because of very limited supplies (especially chemical like food flavour, PG, VG - they ussually are the fake things that come from China, and very poison. And of couse, no nicotine liquid at all, it is impossible to find it in my country), I have to find my own way to DIY e-liquid. And after several nights os thinking, this is really my journal.
1.
PG and VG: I have found out one Vietnam chemical company sell it, but they do not retail, they sell for every 10 liters once. After 30 minutes of convincing, they agree to sell for me a bottle of 500ml VG and another is PG. (cheap)
2.
Nicotine liquid: I bought some Liqua liquid at 24mg nicotine (70/30 PG/VG) (it's quite expensive) with bright tobacco flavour, and I will calculate to reduce it later. Bright tobacco flavour is light, so it do not affect my mix much.
3.
Flavour: Some of Vietnam company sell it, they can be trusted, but they do not retail. They just sell for every 1kg each flavour, and I can not convince them

. I can not buy 1kg of one flavour and use it to the rest of my life, right?

. There is my solution: I bought 10ml of grapefruit oil (this oil use for making lipstick). Mixing things together, and here my 30ml "
first successful" DIY e-juice :

(wao a lot of vapor

)
- 40/60 (PG/VG)
- 6mg of nicotine
- 5% of grapefruit oil
@Susan~S: by the way, I have already purchased a lot of things including e-juice from
Electronic Cigarette, E-Cigarette, E-Liquid | Heaven Gifts . They are on their way to my hand. Feel so excited. Hope they pass through Vietnam customs
