Don't cut your cycle short man, you haven't even taken the ASVAB yet and your considering ending your cycle that you just started..not a very smart move. As others have stated you will not be tested for any steroids or any of your common PCT items. The only thing they are testing for is usually your common street drugs and also your commonly abused prescription drugs. If you were suspected of steroid use they could order a special test on you but no one at MEPS or your basic training is going to give a shit what you did before you came into the military. Plus ordering a special test to have you tested for steroids would require paperwork and take awhile to complete, everyone in the military has enough paperwork to fill out they damn sure don't want to add more. I am just saying that you finish the cycle and look for a ship date that gives you time for proper pct, don't let the recruiter tell you that your only opening for Basic is a certain date...that's bullshit because they start new cycles all the damn time. Best of luck to you and whatever you decide to do.
