Looking at this, it seems like the drugs used to make someone look like Tzuyang aren't far off

To be honest, there are a few drugs used among bodybuilders that cause insane weight loss.
As seen in the video, one of them constantly raises body temperature, making it a life-threatening drug.
Then there's that animal-related medication. That also causes extreme weight loss, and it even destroys body fat itself.
The downside is constant diarrhea, so you have to stock up on toilet paper for a while.
They have developed things in the GLP-1 area, and since this market has infinite expansion potential,
it seems possible to take those substances bodybuilders used to risk their lives for and make them viable by just diluting or removing the toxicity, right?
