With the exception of Ether2010,, and Formula HT, I think I have used every other single product by Get Diesel.
NOS Precursor was pretty decent, IMO. I have not used NOS Precursor since probably July 2007. I used it more as a nitric oxide product, however it is also good for nutrient repartitioning
I enjoyed R4W (6.0 powder) and Diesel Test over NOS Precursor.
