8.81g
I tried five. They all weigh differently. Between 8.75 and 8.81g

Your scales seem ok, so that just leaves the 10ml bottles not being full. Or they were mis-labelled as VG.

I work on volume rather than weight and must confess that I take a 10ml bottle to contain …… 10ml.
If you were aiming for a 6mg nic content and added more that 2 x 10ml bottles of nic, (which you did) your finished product would be greater than 6mg.
Does this mix require steeping? That, and the additional nic, may well be influencing the current flavour.

When i used 10ml bottles of nic, i often found they contained different amounts.

That’s interesting - I’ll maybe measure out next time I use a bottle.
But, I’m not sure my palette would detect much difference between, say, 9.5 or 10.5ml

1ml isn't a big difference in a 100ml bottle, but in a 10ml bottle it is 10% less nicotine.

So, are you saying you’ve found 10ml bottles to contain as little as 9ml?
That would be quite shocking
Will definitely get the syringes out next time.

I never measured it, but i've noticed different levels visually in 10ml nic bottles.

Maybe your nic shots are 20mg, not 18, could be a mislabel or a production error resulting in a higher nic mg than intended, might be higher than 20mg, it probably happens, but rarely

Perhaps knock up some nic free liquid and combine with the suspicious blend.

 

[Rickster]

It doesn't though. 20ml weighed less on my scales when I added it. So it can't weigh that.

You don't ever get all the full amount out of a 10ml bottle more so with vg.

what use by dates are on the nic nic bottles.
around 6 years ago i was reviewing a very well known dinner person new range and all the nicshots supplied ruined all 8 bottles 480ml. turned out the whole pallet was bad and over 10,000 bottles had to be recalled and dumped.
also as mentioned by John above, when did you mix it and have you let it steep for a good few days. i know custards need months steep but not sure on backy flavours. im guessing a good week or two with multiple daily shakes.
