My best advice for a deca cycle:
0mg nandrolone
500mg test
Xmg of whatever oral
16 weeks of the hardest training and best dieting you can handle.
The more we learn about nandrolone the less appealing it is. The more guys use it the more they report how much it fucks with their heads. Yes, it’s a great mass builder. But so is a little more testosterone and a perfect diet. And testosterone—ever higher doses—don’t pose the risk of mental issues and a broken dick the way nandrolone does.
