BOMT is a selective competitive antagonist of the androgen receptor (AR),      although it is described as an "only relatively weak competitor."  The drug shows no androgenic , estrogenic , or progestogenic activity even at high doses, nor any inhibition of 5α-reductase ,  though it does show weak antigonadotropic effects.     Due to its selectivity for and competitive inhibition of the AR, BOMT has been described as a "true" antiandrogen, similarly to benorterone, cyproterone, and flutamide.  Like other steroidal antiandrogens, BOMT may actually be a weak partial agonist of the AR, as it appears to have the potential for weak androgenic effects in specific situations.  On the basis of animal research , BOMT does not appear to act as an AR antagonist in central nervous system tissues, and in relation to this, does not disinhibit the hypothalamic–pituitary–gonadal axis or increase testosterone levels. 
There are possible side effects of Testosterone Enanthate use, but we will find they are extremely easy to avoid for the healthy adult male. When we refer to the healthy adult male we are excluding the issue of low testosterone. For the low level patient, the probability of side effects will be extremely low. In such a case, the individual is merely replacing what he’s lacking and nothing more. For the performance athlete, the side effects of Testosterone Enanthate will carry a greater probability, but should still be very controllable. Most men can tolerate high levels of testosterone very well. However, as with many things in life individual response and sensitivity issues will play a role. This is not unique to Testosterone Enanthate but holds true with all things we put in our body. In order to understand the possible side effects of Testosterone Enanthate, we have broken them down into their separate categories along with all the information you’ll need.
