tweak you percentage even more, and perhaps try other mango as well and see which one you like the most.

Since 1% sucralose (NOT sucrose, which is granulated white table sugar) doesn't do it for you, try 2%.

And as u didn't state the brand of flavorings, percentages used, breathing/steeping times, I can only reply in general.

If u r a beginner to DIY, I recommend that u start off with single flavor juices until u r familiar enough with the nuances of the flavors u r using to make blended complimentary-flavor juices. Too little and u lack flavor. Too much and u also will lack flavor due to the muting effect. Wrong proportions of each complimentary flavor and it doesn't taste as good as it can be. Learn the flavorings and u will be able to easily make yr own recipes in due time.

However in terms of mango flavors, there are 2 things u can easily and safely (quite foolproof) add which can enhance the intensity and create a more realistic mango flavor: 0.9% saline solution and TFA Jackfruit flavor.

Saline makes fruit flavors appear more prominent, and Jackfruit is a supporting/reinforcing flavor for mango. If you're using 8-10% of whatever brand SINGLE mango flavor, add 0.5% of 0.9%saline, and 0.75% Jackfruit. Experiment with varying levels to see what suites yr tastebuds, but I recommend not going beyond 1.5% with the Jackfruit as it can adversely affect the mango flavor at higher levels.

I don't recommend using flavorings from cake shops because cake flavorings is not the same as eliquid flavorings because it is oil based flavorings IINM and you don't wanna inhale those.

Anywho Regarding your recipe, if you're just using TPA Mango and wanna make a single flavorings out of it here is some info

You probably can take it between 10%-15% of it, or probably even lower to suits your own palate and perhaps combine that with other mango such as CAP Sweet mango or TFA Philippine Mango to give your mango more depth to it.

and lastly, don't just take my word for it because I'm not an expert in mango department.

Lol, you stay around Sri Petaling? I bought my first raw there also. Rm 2.70 for 30ml flavorings but all tak boleh pakai. LoL

If u MUST use flavorings from a bakery supply shop, the only brand I dare recommend is Queen, made in Australia. They have max VG versions. Use at minimum 12%.

As for your Mango+Jamaican Rum juice, try upping the mango to 10% (and introduce supporting Jackfruit flavor @ 1% as I detailed earlier), add 0.5% distilled water/R.O. water/0.9% saline (your choice, but I'd go with the saline), and let it steep for 5 days to a week at least. Max VG juices need some lubricity to bring out the flavor (hence the 0.5% water), otherwise your tongue may be too dried out by the VG and that makes it hard to taste properly.
Here's an article on steeping e juices: http://vaping360.com/steeping-e-juice-e-liquid/

That's mostly because cake flavouring is already diluted and weak concentrate in general. Yes you could get a whole array of flavouring and stuff for pocket change but there's always a catch with cheap things.

Try this if you don't mind;
Strawberry milk
-Strawberry (ripe) 6%
-vbic 4%
- malted milk 2%
- sweet cream 1%

All TFA (The Flavor Apprentice) which cost 10 shmeckles per 10ml but at least you'll get your moneys worth. Or if you like simple Strawberry and Cream just look up Mustard Milk online. Super simple yet super great. And only 2 flavouring as well.

anyone knows where i can find 0mg nic e juice?
