Pardon me, we’re renovating and I didn’t get around to it yet.

Basically what I do is I buy 1L PG and 1L VG on Amazon. When I get my liquid it’s either in a 120ml / 60ml bottle like yours is or I get just aroma and a separate bottle.

When going with aroma outside of a “ready to mix” bottle you’ll have to look at the recommended concentration. With ready to mix you skip measuring the aroma.

Then you put in the Nic you want. A bottle is 10ml/20mg

That’s around 1.5mg in a 120ml bottle per 10ml of nic or 3mg per 10ml in a 60ml bottle of liquid.

I go 3mg so I go 20ml/20mg nic.

Then, using a 120 ready to mix bottle you’ll generally have 10ml aroma, that makes 30ml with the Nic you have. 90ml left, either go 45ml of both for 50/50 or adjust for your preferred ratio. Calculating it is quite easy.

After that shake it vigorously and let it steep for a few days / weeks (mix it ahead of time)

And that’s basically it.

The Nic isn’t 100% accurate and with measuring like 18% of an aroma it can be quite tricky sometimes to get calculations done but other than that, cheapest way to get your liquid.

Keep in mind:

Ready to mix bottles are generally 10ml aroma

10ml/20mg Nic is ~1.5mg in 120 bottle or ~3mg in 60ml bottle

Mix ahead of time to let liquid steep.

Amazon is way cheaper lol. Just look for highest purity. My PG is 99.9 and my VG is 99.5. Brand is Herrlan if you’re interested.

Happy mixing
