If he gets internet send him the link to the Joe Rogan interview of Dr Malhotra. He is a cardiologist that has studied the subject more than anyone else I know. It is three hours long and covers the whole gambit but if you just start at minute 28 and listen for about 5 minutes it will tell him all he needs to know. The rest of the interview will just put additional nails in the statin coffin. The doctor is no slouch or flake.

If he doesn't get Bitchute here it is on Rumble.

He has a book The Statin Free Life but I have not read it.

Here it is on Spotify although I have never used that venue.
