Consider you never see a a champion boxer come from a rich back ground. Growing up with nothing makes you tough. Kids from decent house holds try boxing then after getting hit several times realize it's not a sport but a fight. Same with many MMA guys.
Bodybuilding attracts a lot of insecure guys who need validation that they are a man. To achieve that means they will risk health taking drugs. Then they are walking around getting compliments from the clueless about their manliness. On cycle they are aggressive, confident and steroids work as an antidepressant as a feeling of well being becomes addictive. Once off cycle and months have passed then meekness, nervousness and feeling of depression sets in. Then the muscles leave and working out seems like a waste of time. To add insult any gym time has a negative mental effect because weights that were used every workout seem impossible to lift. The addiction to feel "right" again becomes an obsession. Soon like a heroin addict the craving overwhelms and soon they are at the gym at the trunk of a car of the local gym drug dealer buying their new cycle. After craving for a fix they rush home and fill their syringe and jab their ass. They pop a couple of pills and they know in the morning they are in the come back phase in the gym. In a short two weeks they can feel them self getting stronger, bigger and more confident. Muscle memory along with the chemical assist is working. In just two weeks they can see the change. In six weeks it will be drastic. Welcome to the monkey on your back.
They keep telling them self there is nothing to worry about. Your dealer only gets the legit stuff, right? No counterfeit contaminated testosterone derivatives from China. Who has the technology to fake labels and inserts, right? Now you cycle on and off for about a decade or more. No real career because your sole focus is chasing the syringe life style. Your friends now have houses, families and a career but hell you have muscles. Soon being the popular muscle guy in the club gets old. It becomes embarrassing picking up the 22 year old girl at her house when you're 36 meeting the parents. Your job bouncing, selling juice and the three clients you have personal training isn't a career path. Your aging parents are talking about down sizing and moving to Florida. I guess no more basement for free anymore. The thought of getting an apartment in a hell hole apartment complex fills your thoughts. Now if only you had any savings? Steroids, gas, insurance, clubbing, and life takes every penny. You think if I only learned a trade but at the time it would have interfered with contest prep for that third place engraved metal plate you hang so proudly next to your framed picture of yourself. Maybe you will get back with that divorced older mom. She had a house you could live in. Welcome to bodybuilding.
