Using NPP for better joint support

[pullcraft]

I've read that NPP can really help with joint support and it's a better option than deca because it's in your system a short amount of time. What do you think about 300 mg a week for 10 weeks of NPP? Do you think this would be a good setup or should I run something else? I'm 5'10", 230 lbs., and I'm looking to power lift at 40 years old.
