i am not able to find any USP grade VG because.. duh i dont live in the US.
the best and after much hunting VG i can find is the one in the pic attached.
can i use this?
please see the % values of the items
Sulphated ash 0.005%
chloride (CI) 0.0001%
Suphate (SO 4) 0.0005%
Arsenic (As) 0.0001%
now. these are very low numbers and the bottle clearly shows "Minimum assay" as being "99.5%". Purity.
would you mix with this?
