You know that while sex is great and all, it's no way to live. He still has to make a living, or at least make his way out the door. Plus, if he's become addicted to sex, the possibility of moving from sexual domination to human domination via the pills doesn't seem too far-fetched. He said "just doin the shit, worshiping me, pleasuring me..." The more you think about it, the more uncomfortable you become. You have to intervene before it's too late.
The door's locked, but you decide you have to get in. The front door might attract too much attention, and you don't want a messy confrontation. The back door is a possible option...
You go around the building to the back door. Mike's building is a three-unit, two story apartment building, and while they all have different front doors, the back door leads to a utility and recycling room that has three different back doors for each unit. So you technically have to bust through two doors.
The first door is an external storm door and a thin wooden door that leads into the room from the back yard and parking area. You quietly go up to the storm and try to open it. It doesn't budge. With a little more strength, you pull on the little metal handle, and you hear a metal snap, the lock busting off and the door flying open. Luckily, you keep it from banging against the building and making too much noise. The wooden door has a standard brass doorknob, which is also locked. You pull on the knob to try and bust it, but it busts withing the door, meaning the door still won't budge. With a hope for not attracting too much attention, you pull back and punch through the wood above the door, and pull it out, freeing the broken lock and the door. You wait a moment to see if you've attracted attention, but it seems you're in the clear.
You walk into the utility room. Off to the side, you notice in a recycling bin a bottle that looks very similar to the ones Mike uses to store the pills. Mike's is the only rented unit at the moment right now, and the heightened possibility that he may be trying to reach titanic proportions spurs you on to his back door. Mike's back door is metal with a wood interior. This door is also unlocked. You quietly open the door and walk into the rear of his apartment.
You can hear Mike through the wall in the next room. "That's right ladies, keep stroking and sucking. Within a few hours, I'm going to more man than anyone can handle."
That confirms your suspicions, it seems. You walk into the entryway of the room. "Mike!", you shout. He looks at you with a look of annoyance and displeasure. "Moe, what are you doing here? I'm busy. Go away, we'll talk later."
You stay put. "What's this shit about 'being more man than anyone can handle?' ", you demand. He rolls his eyes as the girls, exhausted, slip off his body. He stands up. He's close to ten feet tall at this point, but you couldn't tell that through the door.
"Come on man, we're freaks now. We'll never fit into society. But we're not outcasts. We're super-strong, super-sized, super-horny gods. We should be on top dude. We can take all the stuff left, grow to be fucking monsters. No one will be able to stop us, we'll rule everything. Look, are you with me or are you not?
You stand at the doorway, thinking. He has a point, and the allure of being the strongest men to ever walk the planet is tempting. But, it doesn't seem right.
