Are Moustafa Ismail’s arms natural or not?

The Egyptian bodybuilder Moustafa Ismail has the largest biceps in the world. His name was recorded in the Guinness book of the world records. This person says that his large arms are natural. Moustafa Ismail affirms that he has the largest biceps in the world because he has too strict nutrition and trainings. The Egyptian bodybuilder eats chickens, almonds and fish each day. The bodybuilder also consumes much water and protein shakes.
However it is obvious that nutrition and trainings play great role, numerous individuals doubt about natural arms of Moustafa Ismail. It is hard to believe that suitable trainings and diets can lead to such increase in arms. Which conditions are responsible for the large arms of the Egyptian bodybuilder?
When it was announced that Moustafa Ismail’s arms were 32 inches, accusations connected with application of steroids appeared soon. Some people suggest that steroids are responsible for the large arms of this guy. What did Moustafa Ismail affirm about application administration of steroids? He said that he had administered anabolic steroids while living in Egypt. Purchase and application of these medicines are legal under laws of this country. These medications are available at any drug store in Egypt. Furthermore, steroids are cheap there. But Moustafa Ismail said that he had to discontinue taking these medications, when he moved to the USA. It is know that purchase and usage of these medicines without a prescription are considered to be illegal under laws of the US. These medicines are bought on the black market by those that administer them in the US illegally. So, Moustafa Ismail stopped administering these medicines after he moved to the USA.
But if even Moustafa Ismail takes anabolic steroids, it doesn’t matter because these medications don’t enhance arms. They are not responsible for Moustafa Ismail’s massive arms.
There are other remedies that can enhance arms. They are named “site enhancement oils” (SEO). Synthol is one of the most often administered SEO. This preparation is administered by bodybuilders. It is taken in order to enhance muscles in circumference. So, it is supposed that the Egyptian bodybuilder administers Synthol. However, Moustafa Ismail says that he doesn’t use this product.
The bodybuilder notes that he is hurt by accusations linked with steroids and Synthol. He has submitted to examination conducted by an independent doctor that hasn’t found  any abnormality in the arms of this guy. So, it is not clear whether the bodybuilder’s arms are natural or not.
