Hello, I hope someone will give me some advice, please. I am happily and so far successfully (beginners luck) making DIY liquid for myself and friends. My preferred vape is a pod vape, MTL with 50:50 salt nic (Voopoo Drag Nano and Finic Fish) amongst others. I do also make 60:40 & 70:30 for friends. I have no way of testing small batches as I cannot buy a new pod for every 50:50 (or 60:40 depending on pod/coil Ω) salt nic recipe I try, and even if I did I still cannot test the 70:40 liquids in my pods. I presume I need some kind of drip(?) device, especially for testing. While I am a fast learner I only started vaping in Feb this year so when it comes to hardware you can see I am pretty clueless. I am not a cloud chaser, stealth vaping is more my thing, but somehow I need the best of both worlds for testing to try and please all the people all the time. Thanks so much 
Are you look8ng for a RDA to test with ??? Sorry but I read twice and don’t see what your asking for… Yes Rdas are the easiest thi g to test recipes on , however you really need to test MTL or Pod Recipes in a similar device in my opinion …I dnot vape MTL.or Pods . I do mix for other people that use them and I have used RDAs by closing off airflow and taking the Power down. This is probably not the best way to test butbit has worked lol
Just like what @fidalgo_vapes said there, if you want to mix for pod, it would be much better to use pod to test it. If you could get the RBA for such pod, that’d be better. Furthermore, each pod vapes differently. Most lacks flavour, while some are on par with most sub ohm tanks. If you know what your friend’s using, If possible, you could borrow it to test.
Same here.
Reading the thread title, my first thought was testing the amount of nic (read as: titration), in which case, the last I knew was there currently is no way to titrate nic salts.
Now if the OP is talking about flavor testing… Are we talking about FLAVORS or testing the VG/PG ratio for a device type?

What you need is a rebuildable pod system. I like the Jester by Vapefly. It’s one coil and you could easily replace cotten. For testing you wouldn’d fill the resevoir but just get the cotten soaked.
Or you could go with a MTL RDA (Mouth to Lung Rebuildable Dripping Atamizer) like the Boomstick Reaper.

Flavour testing
@Gina6 sending you a warm welcome your in the best place to learn everything you need to know about mixing your own juice
Ahh ok. 
Sounds like you’re a fellow perfectionist!
I know there are few folks here who mix for others as a matter of routine… But I think even they will tell you that you’re asking the impossible “to try and please all the people all the time.”
It simply is not possible.
They are going to have to work with you (with enough feedback, and helpful information) as you try and work with them, on finding what flavors they prefer as well as the percentages for their devices.
There’s simply no simple “quick fix”.
It’s going to take more trial and error mixing for others than what it will take for just mixing for yourself. And that’s a tall enough order!
I’m not saying don’t do it (or even, that you shouldn’t be doing it), I’m saying that you are increasing your workload exponentially. (And that’s fine, as long as you understand that, and are willing to do it!)
Thanks, I just thought it would be really nice to at least try and taste test as I go along - it means I get to taste things I would not have bothered to make for myself - if for no other reason than to find out what makes them so popular. A good example is this rebel everyone wants - thanks to friends here I have a recipe that everyone loves - but I have still never tasted it - not even the original - I don’t like Red Bull so I doubt I would like this but you never know… I have made enquiries about that Vapefly Jester but can only import and the cost of delivery is more than the device! Also, they do not intend to restock - so how great a seller could it have been? Maybe there is a new one coming. Were it not for COVID 19 I could just taste on their devices - but the world has changed…
I primarily get berries and fruits from it (the actual soda [original blue can], not a flavor). The most interesting thing to me about it, is that it’s a whole different experience between when it’s ice cold, and room temp!
I love the stuff when it’s ice cold, but I almost won’t touch the stuff when it’s warm/room temp.
So there’s another little added bit of complexity (just for that one mix) for you. 
Do they like it warm, ice cold, or somewhere in between? 
And then there’s the whole “do I need to add WS-23” (or other cooling agent) if they answer ice cold?
As long as you can find what makes them “happy enough” to stay off the cigs, you’ve done a good job IMO!
This hobby (like any) can devour you. Or it can be an enjoyable and continuing learning experience!
You choose, and you have the control! 
Juices will definitely taste different in a pod vs an rda. But that shouldn’t matter because store bought juices are not specifically formulated for pod devices or rda devices. So I wouldn’t sweat the small stuff like this. Buy yourself a decent rda device to test with. Go by what the rda tells ya from testing. If anything, maybe up the flavor percentages ever so slightly since pods don’t deliver flavor as well as rda’s do. But you don’t have to test in a pod to mix good recipes. And what I found with rda testing that made it so easy was that you don’t even need cotton. Just add a drop to each coil and vape. That way you just burn the coil clean to try the next flavor. No need to keep changing cotton.
I started doing single flavor testing when I first got started accumulating flavors. But over time I quit doing that and started researching other recipes using the flavors and coming up with an average number to start with.
Single flavor testing will get you close, but mixing flavors changes things. So for me, my single flavor testing didn’t really tell me what a flavor will do when put up against another flavor.
Once you start using flavors over and over in various recipes, it will just come natural to you how much of your individual flavors to use, because you will have compared them in various recipes. You kinda get to know your flavors the more you use them.
And test your recipes without nicotine 
Hope this helps
This is so true…I do test SF as much as I feel i need to …These days I usually test the more complex flavors ( something like Crumble Topping ) but you still wont know how that flavor will perform until you start vlending it with other Bakery types , creams , fruits etc…I do like the way @Chrispdx test flavors. .Chris adds a flavor to FA MM or FA cream fresh or both .
Yeah, that is a good idea. I am more of a research kinda mixer, and like to look at other recipes using a flavor I want to try. Based on a few recipes and comments I can usually gather enough info on what it might do, along with the amount to use, snd just mix a sample recipe on that. Then if I need to adjust, I do so on second mix.
I have WS-23 will ask if she wants it cooler now - thank you.
Oh wow that is great advice, thank you so much xx
Thank you xx
Battling to get one of these, I have put myself on waiting lists, no luck so far…
I make DIY MTL juices for myself. I test using a Ammit RDA on a cheap adjustable wattage internal battery mod. Either buy or make coils at around the same ohms as a pod, adjust the wattage to the same output as the pod is and play with airflow control to mimic the pods.
Put a new bit of cotton in for each mix you are testing. Remove the drip tip and drip your juice directly onto the cotton until saturated. Remember to test enough to let the flavour come through properly as it will change ad the cotton wears in.
