yes. It is a property of nandrolone, not the ester. The guess part is why nandrolones "lube the joints". The going theory is something about joint cortisol and intracapsular fluid, but this is very iffy. Also, testosterones or anything that retains a lot of water will also have a similar effect. The interesting part is why nandrolones seems to provide this relief with lesser overall water retention. Personally, I don't dig to far into why, I just enjoy it
