Hwung Chul Soon is a professional bodybuilder from Korea. He’s popularly known for winning Muscle Mania their ‘Natural’ championship.

In Korea Chul Soon is a huge celebrity thanks to his acting and modelling jobs.

Natural Claim

On his official website, Chul Soon claims to be natural. However, if you go to any bodybuilding forum, you’ll find people questioning if he is. Fact is, he’s incredibly buff and his muscles look nearly photoshopped.

Frequent readers of our blog will know that just appearance is often not enough to determine steroid use. Therefore we must look at different types of evidence.

In this article, we’re going to find out if the Korean bodybuilder is, in fact, natural, or if he has used steroids.

Drug Testing History

The federation a bodybuilder competes with often says a lot about the bodybuilder. Some are known to be popular amongst steroids users. Other leagues test thoroughly for drugs and only attract real natural bodybuilders.

Muscle Mania, the federation Chul Soon competes with drug tests their top 5 contestants when they come off stage. If any traces of steroids are in the bloodstream, an athlete cannot participate for 24 months.

What’s suspicious about this testing policy is that the tests are not at random; this means a bodybuilder can stop using steroids just in time for it not to show up in the tests.

The federations that are known to attract real natural bodybuilders will perform several tests at random moments making it nearly impossible to use steroids.

To conclude, steroid users can pass Muscle Mania its tests, but this doesn’t automatically mean that Chul Soon uses steroids.

His Transformation

They’re huge!

A natural bodybuilder can develop big shoulders, but this 3-d effect as we can see in Chul Soon is something we usually see in steroid users and rarely in natural bodybuilders.
