Except for Rodriguez, it will never be over. His steroid-stained past will probably keep him out of the Hall of Fame. Rather than accept responsibility, he consistently shifted blame over the years or lied about PED use. When the end of his career was near, however, he finally changed his tune, telling reporters last week at his locker in the Citi Field visiting clubhouse that, “I’ve made more mistakes than anybody.” He also invoked a version of Lou Gehrig’s famous speech when asked if he felt he had been put in a bad position for the 2016 season. “I’m one of the luckiest human beings on the planet,” said Rodriguez.
Testosterone can be administered parenterally , but it has more irregular prolonged absorption time and greater activity in muscle in enanthate , undecanoate , or cypionate ester form. These derivatives are hydrolyzed to release free testosterone at the site of injection; absorption rate (and thus injection schedule) varies among different esters, but medical injections are normally done anywhere between semi-weekly to once every 12 weeks. A more frequent schedule may be desirable in order to maintain a more constant level of hormone in the system.  Injectable steroids are typically administered into the muscle, not into the vein, to avoid sudden changes in the amount of the drug in the bloodstream. In addition, because estered testosterone is dissolved in oil, intravenous injection has the potential to cause a dangerous embolism (clot) in the bloodstream.
Rodriguez wasn’t on Bosch’s regimen yet. But even as he circled the bases, and after the game as his colleagues were praising him for succeeding without steroids -- “That’s a chapter of his life I think he’s turned the page on,” said hitting coach Kevin Long -- Rodriguez knew he’d found the man who would help energize the latter stage of his career. He was one week past his 35th birthday, and he was determined to collect every one of those milestone bonuses in his contract. He wanted to be the lone member of the 800 home run club, Bosch would later say. To do that would take a nature-defying power surge in his late 30s of the sort Barry Bonds had pioneered.
