EQ is created by chemically bonding the Boldenone hormone structure to a undecylenate ester, making the Boldenone into a raw material like syrup. The oily Boldenone Undecylenate can be mixed with sterile oil or a solvent like benzyl alcohol. This creates an oil based suspension that is then injectable directly into the muscle. EQ is versatile enough to be used for both bulking and cutting cycles. With cutting the EQ is stacked with Winstrol and Trenbolone and during bulking is stacked with testosterone and Dianabol (Enanthate or Cypionate). It is recommended that you use cycle aids during an EQ run, both N2Guard and Cardarine. Additionally, Arimidex or Aromasin, both Aromatase inhibitors, are necessary with Boldenone Undecylenate. Either, but not both Arimidex or Aromasin.
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 .
