Yes I agree that Sustanon contains different esters that released over time. But isnt that a good thing? Why is that a pain?
For one, it's a pain because you have to hit it ED or EOD because of the short acting esters (prop). Where as with enanthate, you could get away with 1 or 2 shots a week. And second, it takes over 4 months to clear sust from your system, so recovery will be much more intense and difficult. You won't begin to recover natural HPTA function until months after your last shot with sustanon.
If you are going to be pinning ED/EOD I would much rather use prop. And for BB purposes, having 4 different esters is not to our advantage. How did you plan on using sustanon?
Take a look at this article, might shed some light.

Also, run a search about the "sustanon flu". Some may call it a myth, but it made me feel like shit at times. Men have reported: cases of impotence, chronic priapism, epididymitis, inhibition of testicular function, oligospermia, and bladder irritability. Some people that take Sustanon 250 have reported "flu like" symptoms as well. These symptoms include a higher than normal fever, stomach aches, being tired, etc.
When I tried sustanon on a heavy dose, I felt really groggy and I did get stomach pains. I would get "pumps" at random times, the pump feel you want at the gym, I would sometimes get it before bed. Not fun. I almost felt like I had an ulcer using this stuff. Some, have had no problems at all with it. We all react differently to different substances.
There are many articles floating around out there that can further explain why sust is not the best choice of test to use. It was even covered here on this board a few times, run a search.
