Having tried long and short ester stuff.. ive realized short ester stuff costs less, you get more mg per mg from ml, it is faster in results, harder hitting, etc... i tend to bloat less on this stuff too vs the longer esters... the only down side is more common pinning. The only exception for me is deca and npp, i rather run high dose of deca for stupid size, otherwise tren-a, test-p, mast-p all the way.
