Deca Dick 

The inability to achieve an erection even when sexually stimulated caused by prolonged use of the anabolic steroid "Nandrolone Decanoate," better known in bodybuilding circles as "Deca Durabolin." Deca Dick is featured in the movie "Pain & Gain" (starring Mark Wahlberg, Dwayne Johnson, and Anthony Mackie) in which Anthony Mackie's character, Adrian, is seen masturbating his flaccid penis to a pornographic film but is unable to achieve an erection. Deca Durabolin is one of the most popular anabolic steroids due to its effectiveness in promoting size and muscle growth quickly with relatively mild side effects at medium and high doses compared to other steroids. Nandrolone Decanoate breaks down into dihydronandrolone in the body which acts as an inhibitor of penile erectile function. Bodybuilders experience Deca Dick at dosages in excess of 400 mg per week after 3 - 4 weeks. While Deca Dick is supposed to be reversible (by stopping or reducing the dosage of Deca Durabolin) some bodybuilders have reported a "permanent" effect of both lack of libido and erectile dysfunction that cannot be cured with Viagra or Cialis as well as permanently making a man sterile (unable to produce children).

I had several failures with a couple chicks, it was crazy embarrassing! I then found out what deca dick was and was advised to alter my dosages and get Cialis or Viagra.
