From what I've read, seen, and heard, testosterone is the king. Only problem with test is excessive aromatization. How do people solve that? Usually with either an AI, lowering test and leveraging other things like nandrolone or recently the infamous high masteron low test cycles (great on paper but pretty mediocre in practice), or using good ol' primobolan to keep estrogen at bay. But what about Boldenone? You can also control E2 with Boldenone seemingly. Now it seems that the main problem with Boldenone is its looooong ester that is usually always attached to which makes it harder to plan around, takes a while to build up and clear up, the main reason a lot of people get anxiety from it is very likely that they are lowering their E2 too much and due to having a long ester it takes a while for the dose adjustment to be felt in practice. The main issues with Boldenone are fixed by having it in a shorter ester like Cyp. Now some other may bring up the nephro-toxic nature of Boldenone; however, that is a problem that is no inherent from Boldenone use since that is a branching issue from having chronically elevated blood pressure (which all steroids cause). Probably the reason why Boldenone stands out as more neptho-toxic than other compounds is its inherently better ability to elevate red blood count which thickens your blood, thus increasing blood pressure. If you do your due diligence and control BP as you should if you're using and AAS anyway, then something like Boldenone cyp seems like a really good cost-effective alternative to primo.
