There seems to be some debate as to whether this increases or decreases soreness when combined with test prop, perhaps depending on source. My thought is that NPP is a better choice than Deca Durabolin if you want to run a short (8-10 week) cycle test prop (say 150mg Test Prop/75mg NPP EOD). Deca needs to be run a minimum of 10 weeks and the test 2 weeks after ending deca, that would end the cycle at 12 weeks, in which case you might as well just run test E or something... In any case it would be a worthless advantage if you cant walk or lift your arms because of soreness.
Thoughts?
