Great question. I know everyone is different but my experience with test is less than favorable. I have never ran over 500mg a week but it seems to thin my hair pretty quickly and and i am growing back hair and arm hair. I do not like this. My first experience with nandrolone was in a deca/test cycle. I have 3 buldging discs in my back and about 2 weeks after my first deca shot, the inflammation decreased. I loved that! about 8 weeks into the cycle, I started gaining strength and mass like nothing else! I have ran several cycles since but I have even ran nandrolone higher than test (having to run test higher is bro science. nandrolone doesn't affect everyone the same). Right now I am running 400mg NPP and 200 test cyp. I can avoid the androgenic side effects plus put the mass and strength on I want. Out of all my cycles, the ones with nandrolone in them have been by far the most successful.
Enough of the good stuff, now for the bad. The bad isn't that bad at all, but I need to be clear about all of it. Nandrolone gives me major calf pumps. Sometimes bad enough that I can't do any cardio at all! Also, I do bloat quite a bit on it. More than test. And the last thing is that it makes me smell a little funny when I sweat. I don't have the dreaded deca dick. I don't have a low sex drive or a mood crash from running it higher than test.
