Personally, I think it is a good habit to get into using short esters, unless you are older and willing to take the risk. Long esters linger for a long time and cause long-term suppression. Test E is not so bad, but there is an art to learning how to inject EOD in all your major muscle groups. You might as learn early. Eventually, you will want to move on to masteron, trenbolone, and possibly nandrolone (not recommended).
I'd prefer nandrolone over trenbolone for mass building over the longer term, especially in the first few years..
