I get the first part: I don't think higher BP leads to fatigue and ED, I actually get harder boners when BP is high, fatigue maybe but that would probably be from secondary effect from the high BP.
The second part I don't fully get. Tren activates the progesterone receptor and the estrogen receptor, it doesn't "magnify estrogen conversion" but it may act as a co-binding factor for E2 if it doesn't activate the ER itself. It doesn't matter if you use tren and test together or just test, estrogen will be a problem either way. As for prolactin, I don't get that either, tren doesn't increase prolactin, it either activates the prolactin receptor OR it acts as a cobinding factor for prolactin. However, lowering E2 or prolactin may alleviate side effects from tren, and can introduce other side effects.
Tren is basically a SERM, a SARM, and an SProgestinRM
