When you run tren-a do you dose ED, EOD, or something else? No one loves sticking themselves ED but if you've done both ED and EOD did you see a big difference?
I think you always should aim for as stable bloodlevels as possible, and with the Acetate ester ED pinning is better way to go to reach this.
Some people might not notice the difference regarding gains or sides, but all sides are not shown as obvious symptoms. So I think the general health should be a higher priority than the subjective discomfort of pinning ED. If pinning is a problem, stay away from short esters - problem solved.
