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 steroid 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. 
Each user experiences their own unique feelings when using steroids and coming off the drug. When someone chooses to stop using they can experience a variety of withdrawal symptoms linked to addiction. Symptoms can include mood swings, fatigue, restlessness, loss of appetite, insomnia, reduced sex drive, the desire to take more steroids, and depression. Evidence for steroid addiction is certainly not as strong as it is for other drugs like cocaine or heroin. Though it is clear that people develop a tolerance and dependence on them and willingly experience negative consequences when using steroids - both of which are signs for drug dependence.
Steroids: If you are using steroids for the first time, ring 0417529678 for
information regarding correct technique and safe dosage. This service is confidential

administered intramuscularly, ie: the injection must penetrate the skin and
surface fat to enter the muscle. The most common area to inject into is the
upper-outer quarter of the buttocks.
Injections can also be placed into the outer thigh. Intramuscular injections should be given deep within the muscle and away from major nerves and blood vessels. Water-based steroids are easier to inject than oil-based steroids as the needle on oil-based steroids will sometimes block. Shake all solutions vigorously before drawing up.
