Brazilian “bodybuilder” Valdir Segato, more commonly known as Valdir Synthol, has passed away at 55 years old.

Brazilian synthol user Valdir Segato has passed away at age 55, according to initial reports from Brazilian news outlet UOL News. Better known on social media as Valdir Synthol, the man was an aspiring bodybuilder who used extremely large doses of site injection oils to transform his body into a shockingly bulbous physique of fake muscle. The news comes after various reports that medical professionals warned Segato that his synthol use could lead to limb amputation and serious health risks.

UOL News reports that family directly confirmed Valdir Segato passed away on Tuesday, July 26, 2022. Tragically, this was also the same date as his 55th birthday. The cause of death has not yet been revealed. Family indicated that Segato felt sick at his home and eventually called emergency services. He was rushed to the hospital and shortly after passed away.

Valdir Segato’s physique gained attention over social media in recent years due to the shocking and deformed nature of his fake muscles. As of this writing, he had 1.7 million followers on his TikTok. Segato claimed to have been inspired by bodybuilders Arnold Schwarzenegger and Lou Ferrigno in his journey to transform his physique.

Beyond his internet fame, Segato has also been seen as controversial in the bodybuilding community for giving the sport negative attention – and not representative of the true nature of bodybuilding.

Valdir Segato was also featured in the Generation Iron Network feature documentary, Bigorexia. The film followed a variety of individuals who suffer from muscle dysmorphia – a need to gain extremely large muscle mass for aesthetic purposes. You can see Segato featured in the trailer below:

Valdir Segato was one of many labeled “synthol freaks” who use site injection oils to shape their muscles. While there has been some rumor of slight use among actual competitive bodybuilders, Segato abused synthol so much as to fully distort his body in an inhuman way.

Unlike steroids, synthol does not actually help with muscle protein synthesis or muscle recovery. The oil solidifies under the skin as a sort of body modification. In large amounts, site injection oils like synthol can cause serious health risks.

Generation Iron previously sat down with Dr. Thomas O’Connor, also known as the Anabolic Doc, to discus the grim medical truth behind synthol use and abuse. You can watch it below:

While there is no confirmation that Valdir Segato’s synthol use was directly related to his passing, Segato was repeatedly warned by doctors to stop using.

After being told to stop using synthol by his doctor, Segato insisted that he would still potentially use the site injection oil in the future. Despite having “doubled his biceps” he still wanted to be bigger.

“The doctors tell me to stop it, the advice they give me is to stop using. But it’s my decision to use it because I want to, because I like to.”
