Ken Shamrock was born on February 11, 1964 in the city of Macon, Georgia, USA. Exactly the origin of Ken is unknown, his real name is Kilpatrick. Shamrock was an orphan. He was influenced by the city streets, as a result, in 1979 the young boy was sent to a penitentiary for a petty crime. Soon he was adopted by the California philanthropist Robert Shamrock. It was he who advised Ken to go in for sports.

Shamrock’s debut in mixed martial arts took place in 1993 on the Japanese Pancrase series. After 14 fights, defeating such well-known fighters as Maurice Smith and Bas Rutten, Ken Shamrock, becomes the first Pancrase champion on December 17, 1994. In 1993, along with Pancrase Ken Shamrock performed at the UFC tournament, where in the battle for the title he lost to Royce Gracie. The revenge took place in the main battle of the 5th UFC tournament. After 36 minutes of battle, the referee announced a draw.

Ken Shamrock Admitted that He Used Steroids

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

“You know, I used steroids in my career, but I never used them before fights, I used them in the distant past,” Shamrock said. “I was involved with this, I know the purpose for which it is used,” he said.

Shamrock also shared his thoughts that he would also like to tighten the rules of doping testing and start with a random check for all fighters, rather than checking only those who don’t have money to bypass the testing process.

It should be noted that a few years ago, former welterweight champion Georges St-Pierre decided to retire for this reason, saying that the UFC does not have due doping control. (By the way, you might be interested in UFC steroids situation).

Ken Shamrock’s Possible Steroid Cycle

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

  • Deca Durabolin (nandrolone decanoate). The sportsman has used it to help with joints and protein synthesis. These days Ostarine could have been used for this purpose. Deca is a relatively safe steroid with high anabolic activity. Deca was synthesized in 1962 for medical use. The medication has perfectly proved itself in the treatment of the musculoskeletal system and other disorders of 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 in sports practice. This is the most universal medicine for building muscle mass and increasing aerobic abilities, so it is often used in MMA. It is also used in other sports to achieve physical activity and during cutting after strong steroid means. Its low androgenic activity allows women to use it without fear for the hormonal background. Of course, in such cases the dosages are minimal and differ from those for men.
  • Winstrol (stanozolol). The sportsman has used this drug to stay hard and get lean, while losing fat. Stanozolol was developed in 1960 by the American company Winthrop Laboratories for restorative postoperative therapy and 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 to form a beautiful and pronounced muscular definition, vascularization and normalization of the athlete’s weight. Pharmacokinetic properties of the drug can be used to remove excessive fat deposits. Winstrol does not aromatize and does not contribute to water retention in the body, which eliminates rollback phenomenon after the steroid cycle. The drug is also used in the stages of preparation for competitions. Winstrol increases appetite, increases the content of free testosterone in the blood and increases endurance. This drug is used by swimmers, runners, and MMA athletes.
  • Testosterone propionate (one of testosterone esters). This medication used to help recover from long 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 the active substance in the blood. If you compare it with other testosterones, then it has a number of advantages. Comparing it to such drugs as testosterone enanthate and testosterone cypionate, we can see that the duration of the action is very small and therefore when you make a shot, the active substance starts to work immediately, and this is an advantage if quick results are needed. This advantage is enjoyed by MMA fighters because a fast action time also means a fast time of the medication excretion from the body. This makes it possible to show their bodies clean on doping tests.
  • Cardarine (GW-501516). It is modern doping drug, originally developed as a treatment method for many metabolic and cardiovascular disorders. Officially, GW-501516 is classified as a PPAR receptor agonist. GW-1516 is neither an anabolic steroid nor a selective androgen receptor modulator, and therefore does not cause a noticeable increase in muscle mass. However, it enhances fat burning and improves sports performance.

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