Why is it that Acetate/ Propionate (Short acting) esters, seem to contain 100mg/ml, 150mg/ml max, and that longer esters (Enanthate, Cyponiate) contain 200-250mg/ml (Meaning they contain more active substances per cc)?
It is also strange it seems that the shorter estes (Prop) seems to be a lot more painful than the test enanthate. This seems illogical, since test enanthate hurts less but contains 200-250mg/ml, for the most part depending on your gear
