Yes I think finishinig on the prop is an excellent way to end a cycle. Like you state really prevents the drop off and gets you recovering ASAP when used with proper PCT, which is the ultimate goal. People must realize controlling E while on is also very important.
Prop is such a versitle AAS....if someone could pick one juice i think that should be it, yeah, yeah the frequent injects suck. But it is the easiest to control, and this is important, especially if you ever have to bale out of a cycle.
