If i take on cycle of deca durabolin ( steroids) for bodybuilding , is there a risk of death from over dose , if i have one kidney ? or its ok

Glad you're lifting: You don't die of direct toxicity. I've spent time around gyms and i'd encourage you to reconsider your involvement with anabolic steroids. Even if it's legal where you live, many people will consider it cheating, most women prefer a natural bodybuilder, and you're playing russian roulette with your mind. You may do something you'll regret for the rest of your life. Higher dose, greater danger.
