This guy on this video at 13:51 says Trenbolone causes Alzheimer's through an accumulation of a type of protein (beta amaloid 42 and TAU) in the brain. that's scary. im currently on it.
i have no studies, and can't really understand them very well. mostly because i don't have the patience to read that dry stuff. he said this was found through animal testing, but he did not link the study.
