According to the bodyspace page of J.R. Barthel, he is 6’1″  – 185 cm, 240 lbs – 110 kg at 12% BF. This means that at 5-8% body fat (contest condition) he will have the following stats:



185 cm


215 lbs*

97.7 kg

Body fat:


*There isn’t a bulletproof formula that can reveal how heavy J.R. Barthel will be in contest condition, but if he diets down correctly, there isn’t a reason for him to be under 215lbs either.

Let’s compare J.R. Barthel to bodybuilders who have used anabolic steroids during their prime as IFBB professionals. The references of choice will be the legendary bodybuilder from France Serge Nubret. In his prime, he had the following stats:


Off-season weight:

212 lbs (96.6kg)

Competition weight:

200lbs (91kg)


6′ (182cm)

Body fat


Conclusion: On paper, J.R. Barthel has more muscle mass than former IFBB pros such as Serge Nubret.

How is this even possible? What are modern natural bodybuilders doing to surpass the bodybuilding legends from the past? Back in the day, training was training, and nutrition was nutrition. Not much has changed in that regard since the so-called Golden Era Of Bodybuilding.

2.J.R. Barthel has the Photoshop look.

Just like other suspicious natural bodybuilders, J.R Barthel has the so-called Photoshop look. He looks dry, shredded and synthetic – traits never seen among real natural bodybuilders.

Conclusion: J.R. Barthel is too big. It is highly unlikely that he is a lifetime drug-free bodybuilder.
