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.
