Ran 600 Deca wkly last spring and have gone back to 100/wk maintenance with my TRT to help with pain. Definitely helps at higher dose. We'll see about the low.
My TRT dose is only 200mg/wk and that by itself helped me huge, right now I'm running both my test/deca at 500mg, does seem to be helping a little bit more I'd say because I'm moving more weight around and the pain has been less than normal.
