ive nevr had deca dick, and the deca i just got im not using until next cycle whenever that will be. but i saw a video on youtube saying that the reason deca dick occurs is because nandrolone converts to dihydronandrolone like how test goes to dihydrotest, and the nandrolone binds harder but is less androgenic or something like that. never seen anyone bring this up and thought it was interesting to share.. whatabout like dihydrotrenbolone lol
