Thank you all for your messages!
My stomach, liver, etc. can cope with a small amount of PG, but my skin does not tolerate any PG, so I also have to be very carefull with things like shampoo, soap, etc.
To have to use gloves for each filling of clearomizers when there is a bit of PG in the liquid, I find horrible, but when I don't, I get itchy red bubbles on my hands.
I've been DIYing since November 2012. And I have read tons of information of which a lot was incorrect.
F.e. Strawberry VG and Sticky Bun VG turn out to both contain PG.
In the beginning I used the microwave for a few seconds for steeping, then my ultrasone machine for 30 minutes, cause I read what a flavorshop wrote about steeping (sorry, don't remember the name of that webshop; it was something like: a couple of minutes at noon under a pino in Albuquerque).
I make 20ml bottles of my own mixes and if it were true that the flavor gets better after steeping, the taste of my flavors should become better/stronger after a few days, but I can't notice much (if any) difference.
Yep, I think I'm going to use nicotine again. Don't like the idea, but that would be wiser than back to smoking.
Those of you who use TFA are meaning that they use triacetin-based flavors? Triacetin softens plastic, so I think it can't be healthy for our lungs.
TFA has only:
Absinthe - I have got VG-absinthe from ecblend, and mix it with a bit of liquorice and/or menthol (from Hangsen)
Clove - I did not try this yet, think it reminds me of old fashioned tooth painkiller
Cola - I did not try this yet
Cherry Blossom - don't know what this PG-based flavor has to do in this section!
Blueberry - I have thrown away my Blueberry-liquid by Virginvapor... yuk, don't like fruit as vape.
Root Beer - don't know what kind of taste that is, but I don't like beer anyway
BTW: here they write that you can go up to 20%:
