thank you very much for your replies! I never used sweeteners cause i read that they destroy coils but i think its the time i must start using them.

They will require more frequent cotton changes and coil cleaning, that is true. If you do start to use them, start out low and work up fro there as you prefer, so you minimize the coil killin’ effects.

That’s where the SFT (single flavor testing) phase of DIY comes in. You can’t determine what percentage of a flavor you will like without sitting down and testing each one individually and taking notes as you go. Everyone has different taste buds. I don’t have links right now but advise you do a search on the topic for SFT methods that appeal to you.

People generally say that commercial juice is overloaded with sweeteners but I’ve seen a few recipes and I wasn’t impressed with the amount of additional sweetening. There are recipes that don’t even use additional sweeteners because they opt for flavors that are naturally sweet but the ones I’ve seen are a bit on par with what you see here on ELR.
If you look around in the recipes / clones threads, as well as on reddit, you’ll find a lot of recipes that have been discontinued and have been released to the public.
For example
https://www.reddit.com/r/DIY_eJuice/comments/3yzu1e/vicious_vanilla_happy_new_year_everyone/
etc etc
Studying those recipes might give you an idea of how other mixers (pro and diy) achieve certain things. Knowledge of flavors and their workable ranges is also very helpful so see how far you can push them… so find some small bottles and do some flavor testing. Initially a flavor will give very little flavor, it’ll build up the more concentrate you use and at a certain point it will start muting or give you off flavors (soapy, floral, burnt rubber, … depends on the concentrate).
This video is part of a series and shows how you can quickly guage what you can get out of a flavor. Once you get your range, let a few different bottles with different strengths steep to see how the flavor develops and maintains (or not).
(these techniques work across manufacturers, not only for flavorah)

As far as flavor percentages that also comes down to using a mouth to lung tank or sub ohm since you’re worried about coils I’m guessing you don’t build. Most of the 5 star rated recipes on ELR from 2015 2016 etc were made for mouth to lung tanks so maybe start there

im building of course! I had another problem as i was creating eliquids with very thick vg without knowing that i can dilute it with water for injection and my coils were holding 3 days maximum before rewicking. Now i solved this problem by diluting it.

How do you do that if I may ask?

i am buying vg from an online pharmacy. Its very thick and i buy also water for injection small bottles of 10 ml. I add 90ml of vg and 10 ml of water for injection and vg becomes the same consistency as pg!

Don’t be like me and try to vape cola. Stupid! It was a dripper or it would have simply leaked out of the tank. But it was terrible! Ah, dumb me.

A lot of commercial juices use more Additives than DIY does such as Sweeteners , Malic , etc they also push the flavors as high as possible…IMO the amount of sweetness is what you are comparing , and sucraose will make things stand out , give more mouthfeel etc

Agreed. I’ve had more than a few pro-mixers tell me that if they aren’t mixing above 15% they are cheating their customers.
