As pgerardone stated, anti-e's are required to have on hand, just like clomid, if you are taking an aromatizing AAS then you need anti-e's on hand. If your just taking 250mg test a week for labido, you wont necessarily need anit-e's, but if you happen to react harshly, you will be wishing you had them. The point is, some like a little bloat, its helps with strength, others like to stay lean, dose needs to be adjusted according to your goals and how you respond. Having them is equally important no matter weather you front load or not.
