Donte Franklin

Donte Franklin
Donte Franklin is a genetic freak with his muscle-building DNA being 1 in million. If he were to take steroids and get shredded to the bone, Donte would give any Mr. Olympia competitor a run for their money because of how ripped natty arms are as well as thick pecs that many believe make up one’s midsection
Franklin also has an awesome chest upfront which makes him look even more muscular than what you see on TV or magazines where they usually only focus around your backside area.
Donte is one of the biggest natural bodybuilders in this industry. He competes at both INBA and NANBF, which are two federations that conduct thorough testing throughout their respective seasons to catch any potential steroid users.
At 18 years old, Donte was already a hefty size. Proving that he’s been born with the genetics to be huge!
Simeon Panda

Simeon Panda
Simeon Panda is one of the best natural bodybuilders on earth, and at 16 he already had a mighty physique. He doesn’t grow much after this though; it’s all about dieting for him now to get shredded! Consequently, Simeon has landed several lucrative sponsorship deals (including MyProtein).
He’s a natural bodybuilder who never reached new muscle mass through sudden increases in training. His gains have been slow and steady, which makes him even more believable as someone with exceptional genetics for building quality lean tissue!
Ron Williams

Ron Williams
Ron Williams is arguably the most decorated natural bodybuilder in history. He’s been on stage at more than 250 competitions, from being Mr. Natural World to Mr. Universe and everything else! Here are just a few titles:
- 7-time Mr. Natural Olympia
- 7-time Mr. Natural Universe
- 7-time Natural World
- Hall of Fame Inductee (2008)
Sadik Hadzovic

Sadik Hadzovic
Sadik is a big boy. Every year he gets shredded for the Mr. Olympia Men’s Physique category, showing one of the best V-tapers the world has seen. Before modeling, he was a model and was pretty much as big as he is now. If Sadik was taking steroids, surely he would have gained weight since switching to bodybuilding?
The proof that this person has not taken steroids is that he has not changed his body.
Jamie Alderton

Jamie Alderton
Jamie Alderton is a natural bodybuilder from England. He’s sponsored by Grenade, a supplement company. Jamie already had exceptional muscularity at 13 years old.
BNBF and Musclemania are the two federations that do natural bodybuilding. They test for drugs at random times so you might get caught if you take steroids.
Steve Cook

Steve Cook
Many natural bodybuilders do not look as good without a shirt. It is like they are swollen. But Steve Cook is an exception. He does not need a shirt to show his muscles off, and we can see how defined his biceps are even if he wears a loose t-shirt.
Steve was always very muscular in high school when he played American football, and he hasn’t gained any size since. Steve is good at dieting and can lower his body fat %, rather than adding muscle.
Mike Thurston

Mike Thurston
Mike started to build muscle before he even got to Grade 4. At 10 years old, he already had muscles and sizes that were bigger than most other kids his age. It was clear that if he kept developing at the same rate, he would become a strong person.
Without taking steroids, he grew bigger. This helped him become a successful natural bodybuilder.
Anton Antipov

Anton Antipov
Anton Antipov is a model and bodybuilder. He competed in competitions that have the letters “NPC” and “IFBB”. He’s won many of these. Anton started lifting weights when he was in 2004. He also began to eat more food.
Anton has genes that are good for packing on muscle. Even though he wasn’t eating much food, he was still more muscular than 99% of other people who work out.
Rob Riches

Rob Riches
Many people heard that Rob had failed a drug test. They thought that he was using steroids. But all the evidence says he is not.
At age 21, Rob signed up for LA Muscle. Now he is as big as before. He didn’t gain many sizes. One of the signs that someone is a natural bodybuilder is if they don’t grow much after their first growth spurt at the gym.
Rob is a dedicated and knowledgeable bodybuilder. He shares his workout routines on social media to help others.
Ryan Terry

Ryan Terry
Ryan Terry is a sponsored athlete for Gymshark, USN and the Arnold Classic Men’s Physique Champion.
He hasn’t failed any drug tests during his time with the UKBFF or any other organization.
Conclusion
Many people these days can build their muscles without the use of steroids. You need to work hard and train for many years, and then you can also get good results without using steroids.
If you want to have the same effects of bodybuilding, then use a steroid alternative called D-Bal. It gives the same effects as the steroid Dianabol but it does not give any negative side effects.
