Bulk Juice

Chapter 1: The First Bulk

I push open the door to the apartment and step inside. My tank top is wet with my sweat as I am still cooling down from my evening work out. I toss my gym bag on the couch and go to the bathroom.
Checking myself out in the mirror, I admire the physique I earned through 4 years of baseball. My arms were toned and impressively muscled. I sported respectable back and pec muscles, giving a fair bit of width to my frame. My legs were well defined and strong, accentuated by two firm buttocks. I smiled in the mirror as I flexed. I recognized that this was the body many men strived for, but it was missing something for me: I wanted to be bigger.
All throughout high school, I had to stay light in order to maintain my speed. Now that I was out of baseball, I decided to pivot to bodybuilding, with the goal of packing on as much mass as possible. For as long as I could remember, I envied bodybuilders for the huge amounts of muscle they had. I knew that I was destined to be as big as them one day.
Today, hopefully, was when that would happen. I left the bathroom and went into the kitchen. On the counter was a large container of what appeared to be protein powder labeled "Bulk Juice". According to the not-so-legal website I ordered the stuff from, this drink had the incredible ability to cause instant and extreme muscle growth. It all sounded too good to be true, but I caved into curiosity and ordered it.
I read the directions on the container, which say to take one scoop mixed with water. There was a warning directly under the serving directions as well: "WARNING: DO NOT EXCEED ONE DOSE" I wonder what the consequences possibly could be. I decide not to take any chances and carefully measure one scoop of the mixture into my shake bottle. After mixing the drink with water as directed, I begin to tip the shake into my mouth.
I am immediately hit by the sweet taste of vanilla. It felt strange for a drink made only from a powder, but the texture was similar to melted ice cream. Before I realize what I am doing, I let out a moan as I tip the cup further up, starting to chug the creamy mixture. Damn... this stuff is good...
The shake is gone shortly after I began to chug, going down in just a few huge gulps. I belch loudly as I set the cup down, surprised by how fast I drank it. Shortly after setting the empty shake down, I feel a deep gurgle in my stomach accompanied by a warmth in my entire body. The warmth is followed by an aching pain, as if I had just woken up the day after a full-body workout.
I groan as my muscles grow hotter and instinctively look down at my body. My jaw nearly drops from what I see. Before my eyes, I see my arms swelling up. My biceps fill out like baseballs turning into softballs. My shoulders are broadening as my upper body swells with new muscle. My pecs balloon out and stretch my already tight tank top, revealing the firm nipples under the wet fabric. My hands move towards my legs, which thicken like tree trunks. Fuuuck... I'm getting huge... I peel of my tank top to reveal my gigantic chest. My once bare torso seems to have grown a heavy dusting of brown hair, forming a lush carpet across my pecs and a thick treasure trail down my stomach. My abs were extremely well defined, cutting a striking v shape into my torso.
Once the feeling of growth stopped I go back to the bathroom. According to the scale, I am now a monstrous 250 pounds, a nearly 70 pound gain from my previous weight of 182. I look into the mirror and barely recognize myself. I absolutely tower over everything in the bathroom and notice that I must have grown at least 3 inches taller from my original six foot even. I scratch my face and notice a thick stubble dusting my square jaw. I flex in the mirror and assume the stance of a world champion bodybuilder.
Almost by instinct, I return to the kitchen and prepare another dose of the shake. I need more... I have to get bigger... I chug the shake in its entirety before remembering the warning on the label. I slowly set the shake down in a moment of clarity and check the label again. Under the warning, there is another block of text in a smaller text: "Consuming additional doses may result in unwanted fat gain. Bulk Juice is not responsible for adverse effects from improper use of product."
As I read the message, I set the tub down. I feel the familiar growling in my stomach, only much, much louder.
Fuck...
