Testosterone cream was what gave Charlie Sheen “tiger blood.” The star reveals that his bizarre behavior — including coining his infamous tagline “Duh, winning!” — after getting fired from CBS’ “Two and a Half Men” in 2011 was from taking too much testosterone.

“That was a very specific period of time that did feel very out-of-body and very just detached from all things real,” he tells Dr. Mehmet Oz in an interview to air Wednesday on “The Dr. Oz Show.” “I felt superhuman during some of that.”

After getting canned, Sheen publicly went to war with his old show and its creator Chuck Lorre, quipping in interviews, “They picked a fight with a warlock,” “You can’t process me with a normal brain” and “I am on a drug. It’s called Charlie Sheen. It’s not available, because if you try it once, you will die.”

In hindsight, the star, now battling HIV, tells Oz: “It was a lot of highs and lows. I was taking a lot of testosterone cream, and I think I went too far with it. It was kind of like a borderline . . . not a ’roid rage, but a ’roid disengage.”

Sheen, who even took his act on the road in a train-wreck live tour called “My Violent Torpedo of Truth/Defeat Is Not an Option,” now says, “That’s the stuff that I do look at [and] cringe a little . . . It was nice to give people a bunch of slogans and T-shirts and all that. [But] the rest of it was a lot of work.” And, “There were things about that person that were empowering, that were vibrant . . . but I didn’t like the anger. I tend to be victimized by my anger at times.” At the time Sheen also filed a $100 million suit against Lorre and Warner Bros. Television, which was settled.

On Oz’s show on Wednesday, Sheen also opens up about his relationships with exes Brooke Mueller and Denise Richards, the latter of whom is suing him for selling a house he gifted daughters Sam and Lola in a trust. “I’m basically being punished for giving her a house. It doesn’t make any sense,” Sheen claims. He added of the bombshell lawsuit Richards filed against him in January for $1.2 million, “My thought was, ‘She’s burning down the bank and then trying to rob it.’”
