i am imagine you'd blow up quick, but it would be a whole lot of water, and the gains might be hard to keep....i'd also be a little afraid of the speed of mass gain, in terms of joint heath, stretch marks, etc....remember, faster compounds shut you down faster than do slower, longer esters. after 4 weeks you will be suppressed, but recovery will certainly be quicker. i did 15 days of test base TD and superdrol, gained 10lbs, and never felt like i wasnt producing plenty of my own test. the whole PCT i had good libido and mood. give it a shot, it's only a short commitment after all.
