This guy worked his way up to 46.2G, the "highest known acceleration voluntarily encountered by a human": https://en.wikipedia.org/wiki/John_Stapp https://en.wikipedia.org/wiki/John_Stapp Not without problems though. He "sustained a fracture of his right wrist during the runs on two separate occasions, also broke ribs, lost fillings from his teeth and bleeding into his retinas that caused temporary vision loss". This is during short periods (of deceleration), so very different from SpinLaunch's launches.
