As has been posted here deca super saturates the progestin receptor leading to severe shutdown, plus because its metabolites are so long lasting, the effects can be seen for quite a while after, dostinex, or bromo are you best choices as dopamine agonists, just dont use either with nolva during pct as it can increase the amount of tamoxifen circulating in the blood, and as bromo is a cytotoxic agent that could increase the risk of blood clots quite dramaticly.
