Yeah probably Chinese - was it 100% PG? If so, it was almost definitely the Chinese stuff.
Did it have a flavor name?
You can get the Chinese Dekang PG stuff cheap at LiteCigUSA.net and elsewhere
and Liberty-flights.com might have a different kind of PG - not sure
Personally, I like juices around 70pg/30vg. The nicotine makes my tongue sore in 100% PG - I need it smoothed out with some VG.
