Ken Shamrock (AKA “The World’s Most Dangerous Man”) was probably one of the most famous mixed martial arts (MMA) athletes. Ken was a superstar in the Ultimate Fighting Championship, and now he’s in the UFC’s hall of fame. However, similar to a lot of famous fighters, there were speculations about his use of steroids.

Ken Shamrock’s Bio and MMA Career


Ken Shamrock, a “military brat,” was born on February 11th, 1964 in the city of Macon, Georgia, USA. His dad, Richard Kilpatrick, was a US Air Force enlistee. His mom Diane worked as a waitress and dancer.

At age 10, he became an orphan. The city streets influenced him and, as a result, in 1979 they sent the young boy to a penitentiary for petty crime. Soon he was adopted by the Californian philanthropist Robert (Bob) Shamrock (1942-2010). He advised Ken to get into sports.

At school, Ken Shamrock practiced freestyle wrestling. After graduating, was carried away with pro wrestling and became more active in the industry. From 1990 to 2009, Ken was a regular participant. Ken Shamrock acts under the auspices of such organizations as SAPW (South Atlantic Pro Wrestling), TNAW (Total Nonstop Action Wrestling), and WWF. In this field, he was victorious and prosperous.

Shamrock’s debut in mixed martial arts took place in 1993 on the Japanese Pancrase series. After 14 fights, defeating well-known fighters Maurice Smith and Bas Rutten, Ken Shamrock, becomes the first Pancrase champion on December 17th, 1994.

In 1993, along with Pancrase, Ken Shamrock performed at the UFC tournament. In the battle for the title, he lost to Royce Gracie. Revenge took place in the form of the 5th UFC tournament’s main battle. After 36 minutes, the referee announced a draw so Shamrock wasn’t vindicated then.

But three months later, in a fight against Dan Severn, Ken stepped up to the plate and won the belt. However, Dan Severn regained his title in a year. After this short-lived victory, Ken performed in both the UFC and PRIDE. Unfortunately, despite several serious wins, he could not repeat his success. For merit and contribution to the development of mixed martial arts, Ken Shamrock is included in the UFC Hall of Fame.

Ken Shamrock is also a coach. In 1994 the fighter established his “Lion’s Den” club where UFC champions Oleg Taktarov, Maurice Smithy, and Frank Shamrock trained. The club was based in Lodi, California but has recently transferred its headquarters to Reno, Nevada. The club also features the fighters Guy “The Sandman” Mezger, Vernon “Tiger” White, Jerry Bohlander, Tra “Trauma” Telligman, Pete Williams, and Mikey “The Eastside Assassin” Burnett.

Ken Shamrock got married twice. He’s actively involved in bringing up seven children with his second wife Tonya. Ken has a younger half-brother Frank Shamrock (a UFC champion in the light heavyweight category).

Ken Shamrock Admitted He Used Steroids

Ken Shamrock was often accused of using steroids when doping control in the MMA was not developed, and sometimes, this control was completely absent. In 2014, during the Inside MMA program, Shamrock admitted that it was true, he used steroids throughout his career. But he was cautious enough and used them before performances in the MMA.

Shamrock also shared his thoughts on how he would also like to tighten the dope-testing rules and start with random checks for all fighters, rather than checking those who don’t have the money to bypass the testing process. Rather ironic considering his own confessed use.

In 2016, Bellator 149, featuring Ken Shamrock, Royce Gracie, Kimbo Slice and Dhafir Harris (Dada 5000) as headliners, was mired in controversy. Kimbo and Ken both failed post-battle doping tests, however, the banned molecules weren’t revealed.

A few years ago, former welterweight champion Georges St-Pierre retired for this reason, saying that the UFC does not have due doping controls in place to cope with rampant use.

Ken Shamrock’s Possible Steroid Cycle

According to the Evolutionary website, Ken has probably used the following anabolic drugs and PEDs:

Deca Durabolin (nandrolone decanoate). The sportsman may have used it to help with joints and protein synthesis. These days, Ostarine (Enobosarm), an investigational selective AR modulator developed by GTX, could be used for this purpose. Deca is a relatively safe steroid with high anabolic activity. Researchers synthesized it in 1962 for medical use. The medication has proved itself in the treatment of musculoskeletal system disorders and other issues with the bone system. Over time, the drug began to be used in maintenance therapy for HIV patients. Noticing the positive properties of the hormone, athletes began to use it in sports. Today, it’s one of the most universal medicines to build muscle mass and increase aerobic abilities, so they often use it in MMA. They also use it in other sports to achieve physical activity and during cutting after strong steroid cycles. Its low androgenic activity allows women to use it without fear of hormonal reprisals. The dosages should be minimal.

Winstrol (stanozolol). The sportsman might have used this drug to stay hard and get lean, while losing fat. Stanozolol was developed in 1960 by the American company Winthrop Laboratories. Its initial applications were restorative postoperative therapy and the treatment of anemia. It was also used in veterinary medicine to treat weakened animals. In the middle of 1980 this medicine became widely used in power sports thanks to the fact that it enables fighters and bodybuilders to craft a beautiful and pronounced muscular definition. It assists with vascularization and normalization of the athlete’s weight, too. Its pharmacokinetic properties can be used to remove excessive fat deposits. Winstrol does not aromatize and does not contribute to water retention in the body, which eliminates the rollback phenomenon risk after a steroid cycle. The pharmaceutical is also used in competition preparation stages. Winstrol boosts appetite, increases the content of free testosterone in the blood, and elevates endurance. This drug is used by swimmers, runners, and MMA athletes among others.

Testosterone propionate (testosterone ester). This medication is used to help sports persons recover from exhausting workouts and build muscle mass. Testosterone propionate is an injectable solution that is an esterified form of a hormone with a reduced period of action. This means that injections during the cycle should be made daily, or at most, every other day to maintain the right concentration of active substances in the blood. If you compare it with other testosterones, then it has several advantages. Comparing it to such drugs as testosterone enanthate and testosterone cypionate, its duration of the action is small and therefore when you take a shot, the active substance works immediately, and this is an advantage when quick results are needed. This plus point is valued by MMA fighters because a fast action time also means a fast medication excretion time from the body, making it possible to use this med and then display clear test results.

Cardarine (GW-501516). This modern doping medicine was originally developed as a treatment method for many metabolic and cardiovascular disorders. Officially, GW-501516 is classed as a PPAR receptor agonist. GW-1516 is neither an anabolic steroid nor a selective androgen receptor modulator. Hence, it doesn’t cause a noticeable surge in muscle mass. However, it enhances fat burning and improves overall sports performance.

Disclaimer: This steroid cycle is our opinion. We aren’t claiming that Ken used anabolic steroids and other performance-enhancing meds.
