Another thing: You are not Jay Cutler or Ronnie Coleman or Arnold Schwarzenegger or anyone else. The things that some of those men do to their bodies in training would destroy yours. Why is that so? Because they are taking/took enough drugs in a month that they'd be 250 pounds and ripped if they never lifted anything much heavier than their pill bottles (an exaggeration perhaps, but if you'd seen some of these top pros train you might be surprised to find that they don't train as hard as you do - steroids make the muscles stronger but don't do much for the joints, so some of these men actually can't train heavy anymore ...the weights they use in photoshoots are made of styrofoam and plastic). You have about as much in common with the average pro bodybuilder as you do with a lowland Gorilla. Seem a bit far-fetched? Well, I've heard of competitors spending upwards of $90,000 a year in drugs. Think that your body, with it's natural hormone levels, can compare to that? If you do you're dreaming. Sorry if I'm bursting your bubble here, but you had to find out sooner or later. So WAKE UP NOW, before it's too late and you've spent years wasting your time following Jay Cutler's biceps routine. It happened to me. I wasted almost 10 years on their drug-dependent routines. If you don't be careful you may too.
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.
Heavy consumption of the essential amino acid lysine (as indicated in the treatment of cold sores) has allegedly shown false positives in some and was cited by American shotputter C. J. Hunter as the reason for his positive test, though in 2004 he admitted to a federal grand jury that he had injected nandrolone.  A possible cause of incorrect urine test results is the presence of metabolites from other AAS, though modern urinalysis can usually determine the exact AAS used by analyzing the ratio of the two remaining nandrolone metabolites. As a result of the numerous overturned verdicts, the testing procedure was reviewed by UK Sport . On October 5, 2007, three-time Olympic gold medalist for track and field Marion Jones admitted to use of the drug, and was sentenced to six months in jail for lying to a federal grand jury in 2000.
