Just as an update from my poking around about what's been posted, and to offer some information:
Summary for
Juice Mafia:
Not all juices have reports. PG/VG ratio varies, with some having up to 100% VG. As to the juices with reports published, each juice page with a report will have a "Click here to see report" link. That makes a
custom Google search quite handy.
NicVape:
NicVape doesn't publish reports in advance, but each bottle arrives with a Lot Number, which can then be checked online to see the actual report. Not sure I'm sold on that, but to each his/her own. At any rate, most of their juices are a 50/50 blend, though they do have a
Wild Side line that's a 30 PG / 70 VG ratio.
Vapor Bar:
Vapor Bar published
a big report on all of their juices, and identified what's diketone free and what isn't. However, that test is over six months old. Most of their juice is in a 50/50 blend, though their
Forbidden Custard line is in a 40 PG / 60 VG blend.
The Clean Vape:
So far, Clean Vape has
only posted results on two of their juices. I'll try reaching out to see if they additional testing planned. At any rate, they offer a 30 PG / 70 VG for their juices.
Mountain Oak Vapors:
Mountain Oak offers test results for each juice, which will be a link on the individual juice page. Some are broken links, sadly enough, but their diligent efforts in this regard leave me pretty comfortable with the links (they just need to work out some kinks in their system, IMO). At any rate, most of MOV is a 50/50 blend, though they do have an
Enthusiast Series with higher VG (their
Chai Tea Latte, for example, states "at least 70% VG").
