Well blood work is the only true way to tell if you are ready. If your gear is bunk, there is a reason for it. Especially if you have multiple cycles under your belt and you have personal experience to compare to. 3 lbs on m-drol alone is even pathetic. With a good diet 12-15 isn't unreasonable.
However, if you don't feel shut down, your libido is good, you don't have a problem getting it up and you aren't depressed and pathetic I'd say go for it. Test E will take at least 4 weeks to kick in but can and will shut you down naturally nonetheless.
