i am currently on NPP w/ test prop.... I shoot NPP @ 200mg eod and Prop @ 30mg eod and I am having amazing results..... Npp can be shot anywhere from ed up to e4d... Ideally you want to shoot no later than e3d because you dont want to have declining blood levels, you want to keep your blood levels continually stable.... Also, a simple trt dose of test is all that is needed to keep your sex drive up and running.... it is a myth that you need to run test at an equal or higher level to the 19nor's....
another benefit to the phenylpropionate ester over the deconate is that you will have less to minimal bloating.. NPP is awesome s h i t!!!!!!! have fun....
