Another way of looking at it is that some adults who understand the steroid use in the NCAA choose to compete on a level playing field with the many others who are doing the same, rather than the many others who are not. It's how it is.
Sure, anyone can choose not to use and see how that goes for them in football, including college.
There are plenty of colleges who have players who seem to be not athletes at all (judging from speed, agility, or even obviously careless appearance) and so it's not as if a truly talented player who chooses to stay natural can't get a spot somewhere. Probably at a school that still offers a fine education, if that's what it's about?
If the NCAA actually wanted steroids out of college football, then with the billions of dollars they bring in, they could afford random drug testing during the year, just as baseball has always been able to afford but deliberately chose not to do.
This isn't my basis for the above, but for illustration: http://espn.go.com/gen/s/2000/1207/929862.html
As personal opinion, worth nothing more than that, it's somewhat like drivers entering a coast-to-coast car race with a rule that the speed limit can't be exceeded at any time. But in fact, most of the drivers choose to do what they can when they don't see a cop. Yup, it's unfair to those drivers who want to follow the rule. They'll still get to be in the race but sure won't be hoisting trophies for going 70. How mad is it reasonable to get at the faster drivers who don't get caught by the cops?
To further the analogy with sports, we'd have decades of the drivers crossing the country in 30 hours or so, and then somehow everybody being in shock and feeling personally betrayed when learning these blurringly fast drivers weren't following the speed limit the whole time.
It's competitive sports in the real world rather than an ideal world.
Just personal opinion and worth nothing more than everyone else's, for sure.
The only study (that I know of) on Halotestin and fast-twitch muscle fibers didn't show that it does anything unique among anabolic steroids. Rather, Halotestin and mestanolone were the only two steroids tested, and both gave the same effect. I don't think you'll get a special benefit from including Halotestin.
In terms of effectiveness and working well together, there's nothing wrong with combining the three you have in mind.
