Just as its fast to build up serum levels, its also fast to clear. Many guys swap out cyp/enth to prop on the tail end of pre-contest cycles for that reason.
There is more actual testosterone in 1mg of test prop than there is in test cyp/enth as well due to the weight of the esters, and the difference is pretty substantial... prop is ~83.72% test and cyp is ~69.9% test as the cyp ester is almost two and half times more massive than propionate.
Some experience less bloat with propionate, but I can't speak to the science behind it. Besides, if you hold water on either, an AI should alleviate it.
