According to Decrypt, billionaire biohacker Bryan Johnson announced on Twitter that he injected Botox into his penis, claiming it increased its length by one centimeter and improved erection hardness, peak systolic velocity, end-diastolic velocity, and sexual health satisfaction. Johnson described the procedure as 'therapy' and part of a 'double-blind, randomized, placebo-controlled prospective comparative study' involving 70 patients with erectile dysfunction unresponsive to standard treatments like Viagra. Johnson's tweet received mixed responses, with some followers questioning the connection between the injections and his quest for longevity. Johnson has invested over $4 million in his pursuit of a longer life and considers the Botox injections as his latest treatment for better erections.
