But the most similar in its properties to boldenone, as oddly enough, turned out to nandrolone. Despite the dissimilarity of the structure of the molecules of the two drugs, and equipoise, nandrolone, and have approximately the same propensity for aromatization (though, of course, unlike that of nandrolone to estradiol conversion takes place without the participation of the aromatase enzyme). Moreover, the androgen receptor stabilization time of these drugs is approximately the same. Nandrolone and equipoise many experts recommend as interchangeable, and believe not entirely appropriate to their one-time use. In my opinion, this is not entirely justified, and that's why.
Tibolone has tissue -selective estrogenic effects, with desirable effects in bone , the brain , and the vagina , and lack of undesirable action in the endometrium and breasts .  Its tissue selectivity is the result of metabolism , enzyme modulation (., of estrogen sulfatase and estrogen sulfotransferase ), and receptor modulation that vary in different target tissues, and differs mechanistically from that of selective estrogen receptor modulators (SERMs) such as tamoxifen , which produce their tissue selectivity via means of modulation of the ER.   As such, to distinguish it from SERMs, tibolone has been described as a "selective tissue estrogenic activity regulator" (STEAR),  and also as a "selective estrogen enzyme modulator" (SEEM). 
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.
