Richard Eugene Piana (September 26, 1970 – August 25, 2017) was an American bodybuilder, businessman, and YouTuber.

In his videos, he often spoke of the mentality and drive of "the 5%", which he said is the percentage of people who are willing to do whatever it takes to achieve their goals.

According to his autopsy report, both his heart and liver weighed twice the average amount for an adult male; it was also noted that he had "mild atherosclerotic disease".

[6][7] However, the autopsy report was ultimately inconclusive on the cause and manner of his death due to the hospital's disposal of all toxicology specimens.

[12] At the age of 18, Piana started a common steroid cycle practice known as "test and deca" that combines testosterone and Deca-Durabolin.

[17] In 2014, Piana asserted that he had experienced some side effects from his use of steroids, including hair loss, gynecomastia (enlarged breasts, which he had treated with medication), and signs of liver toxicity.

[13] He said that when he was competing at the national level, he was taking 20 international units per day of Serostim, a synthetic form of human growth hormone, which would cost about $8,000 per month at ordinary prescription prices (although he was sometimes getting it for free or for about $2,000 through connections with people who had prescriptions for it to fight HIV infection).

[22][23] Their marriage was annulled for having occurred under false pretenses,[24] and he resumed his relationship with Jansen, who was his partner at the time of his death.

His heartbeat was eventually restored, but so much time had passed that brain damage had set in from lack of oxygen.

[27] After the discovery of crushed white powder along with a straw and a credit card on the table in his home, paramedics administered naloxone, a medication used to counteract a possible opiate overdose.

[20] She also said that in the last few days before his collapse, he had exhibited some unusual symptoms including shortness of breath and nausea, and said she was later told these may have been warning signs of an impending cardiac arrest.

[20] After spending two weeks in an induced coma to try to reduce swelling to the brain, Piana died on August 25 at the age of 46.

[29] The autopsy report said there was no evidence of recent injury, appearing to rule out physical trauma as a significant factor in his death.
