Ok I have used both "Angus" and chinese nitros

there is much debate about these two products being from the same scource in china

In the 3 years i have been making fuels professionally for RC i have to say the Chinese stuff wins hands down. it has more poke and the purity level is higher generally speaking

Angus nitro as stated on the Dow chemichal site is 98% pure, it is cut by 2 % with something , but as of the 18th Jan this year the US stopped supply of Angus nitro to australia

Chinese nirto depending on its sourse is anywhere from 99 to 99.9 pure

Interesting thing i have experienced, I bought Angus and Chinese nitro and had both tested and they were the exact same produt.

So either way its all good.

Anly stuff to watch out for is if the nitro has a chlorine smell, if it does id recommend not using it, i have and with little side effects and dang it has some poke but its not recommended for engine use

hope this helps !

Cheers MM
