Limb-girdle muscular dystrophy (LGMD) is a general term for a group of rare progressive genetic disorders that are characterized by wasting (atrophy) and weakness of the voluntary muscles of the hip and shoulder areas (limb-girdle area). Muscle weakness and atrophy are progressive and may spread to affect other muscles of the body. Approximately 15 different subtypes have been identified based upon abnormal changes (mutations) of certain genes. The age of onset, severity, and progression of symptoms of these subtypes varies greatly even among individuals in the same family. Some individuals may have a mild, slowly progressive form of the disease; other may have a rapidly progressive form that may cause severe disability. The various forms of LGMDs can now be distinguished by genetic and/or protein analysis. The various forms of LGMD may be inherited as an autosomal dominant or recessive trait. Autosomal dominant LGMD is known as LGMD1 and has five subtypes ( LGMDA-E ). Autosomal recessive LGMD is known as LGMD2 and has 10 subtypes ( LGMDA-J ).

Pharmacom Labs Oxandrolonos is presented in a 100 tablet box with 2 blister packs of 50 tablets each. Each tablet reportedly contains 10 milligrams of oxandrolone according to the label and packaging. Samples of this product were purchased from a North American-based authorized distributor between the dates of June 1, 2015 and June 30, 2015. The samples were forwarded and received by the analytical laboratory SIMEC AG for HPLC-UV testing on July 20, 2015. The quantitative dosage testing report was completed on August 10, 2015. The product was identified with an expiration date of October 15, 2018 and a batch number of MBMN1. There was no verification code printed on the box.
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.
