I started a prop/tren A cycle last week and I’m concerned about prolactin caused gyno. This is my first time using tren. I’m currently taking vit B and arimidex at .25 ed. In past cycle’s I’ve taken letro because I thought my small existing gyno was caused by estrogen. I feel that letro may have limited my gains so I wanted to try and monitor a weaker AI. My main concern here is to evaluate the effectiveness of the arimidex. I’m going to have regular blood test during this cycle and I’m wondering if I should have my prolactin, progesterone, and estrogen levels checked or just my estrogen and prolactin levels checked?
