nandrolone metabolizes into DHN in the body. that swamps DHT. DHT is our sex hormone so when you get an imbalance of too much DHN vs. DHT you get the dreaded 'deca dick' issues. to offset this i came up with the idea years ago to use a dht derivative which will give you a proper balance so you avoid deca dick. i can say that people who have followed my strategy have a 100% success rate avoiding dick issues on nandroloneswhy ? i never used with nandrolone,
I always keep an eye on estradiol and prolactin
you can also use other dht derivatives but proviron is safe, not liver toxic, and low sides overall. 25-50mg a day is all you need
