PNBA multi-media athlete Adrian Pietrariu shared his 21-year natural bodybuilding transformation. 

You can build an incredible physique with a lot of muscle mass and low body fat completely naturally after years of training efficiently and consistently. Professional Natural Bodybuilding Association (PNBA) 2018 Athlete of the Year, Adrian Pietrariu, shared an astounding transformation on social media, displaying the possibilities of transforming your physique through natural bodybuilding. 

Adrian Pietrariu has a multi-media contract with Generation Iron, INBA PNBA, and Iron Man Magazine. He’s also a 2020 INBA PNBA Hall of Fame Inductee. Pietrariu expressed the following statement below about his transformation:

“21 Years Transformation. The trick is to never stop! Don’t be afraid to work. Be consistent. Understand that you are doing it for yourself. Don’t be afraid to try things and fail. It’s a process that you can’t stop learning. Don’t look for a quick fix. Because a quick fix is exactly what it sounds like. Learn to Love Yourself. Invest in yourself.”

You can see his transformation photo on Instagram below:

Natural Bodybuilding Vs. Bodybuilding

We recently covered everything you need to know about natural bodybuilders’ diets and training lifestyles. Natural bodybuilders must build a top-tier physique without performance-enhancing drugs (PEDs) like steroids. That’s not to say all bodybuilders aren’t natural. However, bodybuilding leagues such as the Internationational Federation of Bodybuilding and Fitness (IFBB) Pro don’t drug test their athletes. Therefore, doping is rampant. 

The INBA PNBA (the most prominent natural bodybuilding organization) vets its athletes through the most rigorous drug testing standards, the World Anti-Doping Agency (WADA). WADA has a complete 2022 list of banned substances. And any INBA PNBA athlete who fails to adhere to their guidelines will be banned from competing and uploaded to the Hall of Shame. 

Therefore, natural bodybuilders follow strict nutrition and training protocols, especially since they can’t use anabolic steroids. Moreover, it takes natural bodybuilders more time to build their physique than steroid users. For example, Adrian Pietrariu’s picture he uploaded is a 21-year transformation. On the other hand, steroids make building lean muscle and losing body fat much easier and faster. 

Many natural bodybuilders will take years off from entering a competition. So they can spend that time building as much muscle as possible before cutting their body fat low for shows. 

Supplements 

Natural bodybuilders also need to be cautious of the supplements they take. Some products have ingredients that are WADA-banned. And these ingredients may be in protein powders, fat burners, creatine, and pre-workouts. For example, former 2021 Natural Olympia Women’s Bodybuilding champ, Jill Kolivoski, failed a drug test administered at the show after taking a supplement she claims had ingredients she was unaware were banned substances. 

So it’s the INBA PNBA athletes’ job to do their due diligence to ensure the supplements they take are WADA compliant. Nevertheless, many natural bodybuilders supplement with vitamin D since often people are deficient in this mineral. And it’s vital for testosterone, energy, and immune support.
