Cutting Pre-Made Juice

[atroph]

Hello I am looking to cut my premade juice 1. to reduce the PG ratio and 2. to reduce the nic as I have a stockpile of 12mg/mL that is way too much for me.

I did some experimenting and found that 2 parts of VG to 3 parts of premade yielded a decent vape.

I was more concerned about the nic content and if my math is correct if the premade juice is 12mg/mL and I cut it like above then I will have a yield of 7.2mg/mL.

Cutting Recipe:
2 parts VG
3 parts premade @ 12 mg/mL

Batch total of 10 mL for simplicity.

4 mL VG
6mL premade @ 12mg/mL
= 12mg/mL strength diluted by 40% or retaining 60% of its potency = 12 * 0.60=7.2 mg/mL

Does my math jive??

Thanks!

Yup. The full computational process is:
C1V1+C2V2=C3V3

So,
(12 mg/ml)*(6 ml)+(0 mg/ml)*(4 ml)=C3V3
V3=V1+V2=6 ml+4 ml=10 ml

Solving for C3:
C3=[C1V1+C2V2]/V3
=[(12 mg/ml)*(6 ml)+(0 mg/ml)*(4 ml)]/(10 ml)
=[72 mg + 0 mg]/(10 ml)
=7.2 mg/ml

The math jives but the flavor will also be cut by that amount so you will loose flavor potency. So Start with a small test batch of let say 5ml and see if the flavor loss is acceptable.

and that leads to this thought... now how about adding flavor to your cutting liquid? Are you talking about vendor ejuice when you way "pre made"?

I have been "diluting" my favorite vendor juice with something DIY that compliments it well. Not so easy to do with complex vendor juices, but I got lucky, and I also vape mostly fruit flavors which are not hard to do.

I actually make a batch of DIY and add about 10 to 25% of the vendor juice.... I go through a hell of a lot of juice a day, and most of it is either DIY or DIY+vendor juice.
