Test Cyp or E

I know we say that Test is Test and that Cyp and E are the same except for 1 molecule. However, has anyone used both of them at one time or another and noticed any appreciable difference?

Hard to answer as most manufactures make only 1 or the other, so most that have tried both have been different brands anyways.

However that said, I do prefer enanthate.

same here

Thanks for answering, BUT, why E over Cyp
