Now: I have my own Estrogen and cake will make me fat, but let's hang out.
Past: Nah man, I'm cool being a guy. But we can still hang out. By the way, where do you keep the cake? Just so I don't accidentally eat any of it, you understand.
Of course! It's in a white box in the refrigerator. There's an ice cream cake in the freezer, but it's infused with spironolactone... which helps with gastrointestinal health!
It can cause blood clots which can kinda damage any organ they happen in, heart attacks and strokes are very likely. It can also cause liver toxicity, gall stones, and even kidney damage as well as a multitude of other awful things.
It also can cause the exact opposite effects that would be desired from Estrogen at high dosage, more estrogen ≠ more changes and more faster please.
In short, it's a bad idea. Can cause a lot of serious damage, and even negate the purpose for doing it in the first place. Stick to the acceptable dose if you want it or need it.
