h2o2
H2O2 is the s***-talking chemical for hydrogen peroxide, the stuff that makes your wounds yell at you and your brain wish it was dead.
My dog got a scratch and I used H2O2 on it, and it howled like I’d killed its best friend.
I put hydrogen peroxide on my finger and it felt like my finger was being tortured.
My sister used H2O2 on her hand and it was like she had a thousand pinpricks.
