It was decades later that the secret behind this spectacular success became known. The East German Sports Federation had, with the help of the Stasi, used Performance Enhancing Drugs or PEDs to ensure that their athletes gained international recognition by winning the Olympic events. This systematic plan had been initiated in 1974 as a means to guarantee international glory through the achievement of gold medals at the prestigious sporting event. Oral- Turinabol , a testosterone derivative was used extensively to improve muscle mass and cut down recovery time. This allowed the German athletes to train harder and longer than other world athletes.
The most commonly used AAS in medicine are testosterone and its various esters (but most commonly testosterone undecanoate , testosterone enanthate , testosterone cypionate , and testosterone propionate ),  nandrolone esters (most commonly nandrolone decanoate and nandrolone phenylpropionate ), stanozolol , and metandienone (methandrostenolone).  Others also available and used commonly but to a lesser extent include methyltestosterone , oxandrolone , mesterolone , and oxymetholone , as well as drostanolone propionate , metenolone (methylandrostenolone), and fluoxymesterone .  Dihydrotestosterone (DHT; androstanolone, stanolone) and its esters are also notable, although they are not widely used in medicine.  Boldenone undecylenate and trenbolone acetate are used in veterinary medicine . 
The HGH benefits are many, and this leads many people to abuse the compound. They believe if they use more, they’ll experience better results, but this is not at all the case. In fact, this is another similarity between HGH and anabolic steroids – both can cause severe side effects when used in high doses or for long periods of time. Per Dr. Alan Rogol, a representative of The Endocrine Society, HGH can weaken the muscles and cause heart disease when abused. He also notes that the bioavailability of oral HGH is too low for it to be effective, so those purchasing so-called HGH pills online are likely throwing their money away. Finally, per the FDA, excessive use can lead to a variety of cancers. This is why the use of exogenous HGH is so heavily regulated.
