Bodybuilder Jay McGwire Details Brother Mark McGwire’s Use of Deca Durabolin and HGH

January 22, 2009 by Millard 4 Comments

Jay McGwire claimed Mark McGwire used anabolic steroids, Deca Durabolin, and human growth hormone (hGH)

Former amateur bodybuilder Jay McGwire, the youngest brother of baseball player Mark McGwire, is fighting for the honor of being the first person to have introduced and injected Mark McGwire with anabolic steroids. The younger McGwire is trying to sell a manuscript entitled “The McGwire Family Secret: The Truth about Steroids, a Slugger, and Ultimate Redemption” that details Mark McGwire’s use of performance enhancing drugs (“Mark McGwire’s One-Eyed Baby Brother Reveals The Not-So-Startling Truth,” January 21).

“Shortly after I won the Contra Costa Bodybuilding Championships in May of 1994, Mark took the plunge. I accompanied him to Sacramento where we met with my supplier and trainer, who explained to him how the different drugs would work on his body and answered a myriad of questions from Mark. Given Mark’s curiosity and lack of knowledge about steroids I saw from Mark, I would be shocked if Mark did something like what Jose Canseco claimed happened back in the early years….[M]ark began to use, but in low dosages so he wouldn’t lift his way out of baseball. Deca-Durabolin helped with his joint problems and recovery, while growth hormone helped his strength, making him leaner in the process. I became the first person to inject him, like most first-timers he couldn’t plunge in the needle himself. Later a girlfriend injected him.”

Jay McGwire seeks to take credit for designing Big Mac’s first steroid cycle that incorporated Deca Durabolin as well as human growth hormone (HGH). Jay McGwire also took credit for introducing his brother to androstenedione shortly after Associated Press reporter Steve Wilstein published the story “Drug OK in Baseball, Not Olympics” announcing the discovery of the legal anabolic steroid supplement in Mark McGwire’s locker in July 1998 (“Great Chase Turns Into Great Debate,” August 25, 1998).

The McGwires, often mistaken for twins, lived together in Northern California while Mark recovered from the heel and lower back injuries that sidelined him for virtually the entire 1993 and ˜94 seasons, and it was Jay, into bodybuilding since high school, who helped redesign the supplement-aided weightlifting program that helped his brother return bigger and better than ever. […]

The key to anything is moderation, but that’s not to say he’s taking steroids because he isn’t.”

Jay McGwire faces stiff competition from others who claim to have provided Mark McGwire with anabolic steroids. Jose Canseco talked about using Deca Durabolin and Winstrol when he and McGwire played with the Oakland A’s as the “Bash Brothers” in 1998 (“Jay McGwire pitching book detailing brother Mark McGwire’s steroid use,” January 21).

In his 2005 book “Juiced,” Jose Canseco wrote that he began injecting Mark McGwire with steroids in 1988, when they were teammates with the Oakland A’s. “I injected Mark in the bathrooms at the (Oakland) Coliseum more times than I can remember,” Canseco said. “Sometimes we did it before batting practice, sometimes afterward. It was no big deal.”

Convicted steroid dealer Curtis Wenzlaff admitted to providing Mark McGwire with Winstrol V, Equipoise and testosterone after he was arrested by Special Agent Greg Stejskal arrested him as part of the FBI Operation Equine (“Who Knew?,” November 9, 2005).

He says he soon picked up McGwire as a client, too. Wenzlaff’s training-session notes show he put McGwire on a mix of Winstrol V, testosterone and the veterinary steroid Equipoise. (McGwire, through a spokesman, declined comment.)

Sources in the Operation Equine steroid investigation even provided specific cycles allegedly used by Mark McGwire (“Hitting the Mark: FBI informants say McGwire was juiced,” March 13, 2005).

The recipe called for 1/2 cc of testosterone cypionate every three days; one cc of testosterone enanthate per week; equipoise and winstrol v, 1/4 cc every three days, injected into the buttocks, one in one cheek, one in the other.

It was the cocktail of a hardcore steroids user, and it is one of the “arrays,” or steroid recipes, Mark McGwire used to become the biggest thing in baseball in the 1990s, sources have told the Daily News.

“My bringing the truth to surface about Mark is out of love,” according to Jay McGwire, “I want Mark to live in truth to see the light, to come to repentance so he can live in freedom”which is the only way to live.” Jay McGwire’s motivations for writing a book about his brother’s steroid and performance-enhancing drug use are highly suspect. Both of his brothers had considerable success in sports – Mark McGwire in Major League Baseball (MLB) and Dan McGwire in the National Football League (NFL) whereas Jay McGwire’s greatest athletic achievement was winning a bodybuilding trophy.

Apparently, Jay McGwire is a born-again Christian who rediscovered God and is doing it out of the goodness of his heart. But it is difficult to believe his motivations arise “out of love” for his brother.

Ex-Fiancee Corroborates McGwire Steroid Claims Made In Book Proposal

Lauren Brown was engaged to Jay McGwire in 1996, the same time he was consistently supplying the former home run king with steroids. She's relieved the truth about Mark's steroid use is finally out.

Lauren Brown contacted us exclusively to share some of the incidents she'd witnessed first hand while she was dating Mark's younger brother. She called off her engagement to Jay in 1996 due to his steroid use specifically "roid rage" incidents. But, even though she has bad memories of their engagement and the person Jay was at that time, she claims he is absolutely telling the truth. [...]

She says that while she was at Mark's house, she claims she saw steroids in Mark's refrigerator or actually "Several tubes of an injectible substance."

She says that she knew well enough that Jay was Mark's supplier at the time and that he also tried to get her to take steroids as well as part of her own training regiment. She did not. Brown also says that the fact Mark so carelessly left his steroids in plain view makes her believe that "he didn't think what they [Mark and Jay] were doing was wrong." [...]

But why is Jay doing this now? Brown said, yes, there is a financial reason for him to do it, but that Jay's born again Christianity has changed him in so many ways that she doesn't think his intentions are malicious.

"Jay should be the one to tell the truth about what transpired. He was a first hand witness. Jay's faith catapulted him to stop steroids and live an honest life. Mark could learn a lot from his baby brother. After all, he was a better athlete with an unfortunate handicap that prevented him from going pro, " Brown said.

Mark McGwire is Thrown Under the Bus Again and Again

Mark McGwire was considered for election to the National Baseball Hall of Fame by the Baseball Writers’ Association of America (BBWAA) in his third year of eligibility. Membership to the Hall of Fame requires seventy-five percent (75%) of the votes. McGwire did not even come close; only receiving votes on 21.9% of the ballots. It appears unlikely that McGwire will make it to Cooperstown after his noteworthy career was tarnished by suspicions of anabolic steroid use. Sports writers have clearly turned on McGwire, as have former teammates, and most recently his own brother. Steroid hysteria has tarnished the career of perhaps one of the nicest baseball players and certainly one of the most philanthropic.
Mark McGwire has become reclusive since retiring from baseball; he has actively avoided the media spotlight while living in a gated community in Irvine, California. His family has been a source of strength during the steroid witch-hunt. McGwire is most certainly deeply hurt that his younger brother is shopping around a book where he claims to have introduced his older brother to anabolic steroids in 1994. Jay McGwire, a former amateur bodybuilder and winner of the 2004 Contra Costa Bodybuilding Championships, writes that his older brother used steroids, such as Deca Durabolin, and human growth hormone (HGH) in a book written “out of love” for Mark McGwire. The book is called “The Mark McGwire Family Secret: The Truth about Steroids, a Slugger, and Ultimate Redemption.”

“Shortly after I won the Contra Costa Bodybuilding Championships in May of 1994, Mark took the plunge. I accompanied him to Sacramento where we met with my supplier and trainer, who explained to him how the different drugs would work on his body and answered a myriad of questions from Mark. Given Mark’s curiosity and lack of knowledge about steroids I saw from Mark, I would be shocked if Mark did something like what Jose Canseco claimed happened back in the early years....[M]ark began to use, but in low dosages so he wouldn’t lift his way out of baseball. Deca-Durabolin helped with his joint problems and recovery, while growth hormone helped his strength, making him leaner in the process. I became the first person to inject him, like most first-timers he couldn’t plunge in the needle himself. Later a girlfriend injected him.”

Steve Wilstein, the Associated Press reporter who discovered a bottle of androstenedione in McGwire’s locker during the thrilling Mark McGwire-Sammy Sosa home run chase in 1998, was the person that made the use of performance-enhancing drugs by Mark McGwire a topic of national discussion in spite of the fact that androstenedione was legal and not prohibited by MLB at the time; McGwire’s baby brother Jay introduced him to androstenedione. But it was Jose Canseco, the main whistleblower in Major League Baseball’s steroid era, who threw his former teammate under the bus and outed him as a user of anabolic steroids in the tell-all book, “Juiced: Wild Times, Rampant ‘Roids, Smash Hits, and How Baseball Got Big.”

”What we did, more times than I can count, was go into a bathroom stall together to shoot up steroids.

“That’s right: After batting practice or right before the game, Mark and I would duck into a stall in the men’s room, load up our syringes, and inject ourselves. I always injected myself, because I had practiced enough to know just what I was doing, but often I would inject Mark as well.”

The accusations in Jose Canseco’s book led to a 2005 Congressional hearing investigating steroids in baseball called “Restoring Faith in America’s Pastime: Evaluating Major League Baseball’s Efforts to Eradicate Steroid Use.” Mark McGwire was subpoenaed to discuss steroids at the hearing along with Jose Canseco and five other MLB players. McGwire did what most defense attorney would advise which is not to admit the use of performance-enhancing drugs, even if true, under oath.

“Asking me or any other player to answer questions about who took steroids in front of television cameras will not solve the problem. If a player answers ‘No,’ he simply will not be believed; if he answers ‘Yes,’ he risks public scorn and endless government investigations.... My lawyers have advised me that I cannot answer these questions without jeopardizing my friends, my family, and myself. I will say, however, that it remains a fact in this country that a man, any man, should be regarded as innocent unless proven guilty.” [...]

“I’m not here to talk about the past. I’m here to be positive about this subject.”

Mark McGwire’s decision to exercise his constitutional rights to avoid incriminating himself may have been a wise legal strategy but it was disastrous as a public relations strategy. McGwire’s refusal to admit (or deny) the use of performance-enhancing drugs disappointed everyone and may have permanently closed the door to the Hall of Fame.

Mark McGwire is one of the most sympathetic victims of contemporary steroid hysteria. Prior to the suspicions of steroid use, McGwire was one of the most well-respected, gentlemanly, and polite baseball players in the league. McGwire was certainly one of the most philanthropic; he founded the Mark McGwire Foundation for Children which awards grants to shelters and programs for physically and sexually abused children. McGwire makes a charitable donation to the foundation in the amount of $1 million every year.

“We catch a glimpse of the future when we look into the faces of our nation’s children...tomorrow’s generation is being shaped today by the environment in which they live,” Mark McGwire says about the goals of his foundation, “Whether or not this environment nurtures them to become caring and productive citizens rests in our hands.”

Sadly, Mark McGwire’s accomplishments as a baseball players and his generosity as a philanthropist will be overshadowed by the question of whether he used anabolic steroids.

Jay McGwire shares steroids secrets by Mike Fish

According to Jay, while Mark was sitting out with a heel injury late in the strike-shortened 1994 season, he talked him into trying a combination of human growth hormone (HGH) and Deca-Durabolin. Jay describes the smorgasbord of drugs as expanding over the next two years to include Primobolan, Winstrol (the steroid that cost Ben Johnson a gold medal at the Seoul Olympics in 1988), Dianabol (Dbol) and Clenbuterol.[/SIZE]

Jay McGwire writes that the offseason regimen featured, as an example, "Dbol [oral, 50 up to 70 mgs/day], Winstrol [oral, 50 up to 80 mgs every other day] and Primobolan [oral, 60 up to 80 mgs/day] for a minimum of 12 weeks." He told ESPN that Primobolan and Dbol were not used as healing agents, rather for "strength, size." He further suggests the doses -- measured in milligrams -- were low for a competitive bodybuilder, though others familiar with anabolic steroids describe them as significant for a baseball player.

"If he was doing growth [hormone] by itself, I would say, 'OK, he is looking for healing,'" says Kirk Radomski, a former amateur bodybuilder who pleaded guilty in 2007 to distributing steroids to dozens of current and former baseball players. "But now he is mixing with anabolics and stuff, and he is looking for strength and size. And to build more muscle."[

Victor Conte, the Bay Area Laboratory Co-Operative founder who pleaded guilty in 2005 to distributing what were then undetectable steroids to a cadre of world-class athletes, said the doping regimen sounds like what might be expected of a bodybuilder. He also said the doses and a 12-week cycle are serious stuff.

"Obviously you're going to enhance performance if he is doing that in conjunction with an effective weight training program," Conte said. "The first thing you are going to see is size. You are using Dbol and this stuff at this dosage, you're going to look like Hercules, if he is doing the weight training.

At 12 weeks and those dosages, this is not baby food."
