Sergi Constance is a twenty-seven-year-old professional bodybuilder from Spain. The athlete shines on the covers of several leading fitness magazines including ‘Muscle & Fitness.’

The bodybuilder also is a successful entrepreneur that runs his own clothing company and works with supplement manufacturers such as MyProtein.

Some of our readers have requested us to find out if this Spanish bodybuilder has used steroids. That’s what we’re going to find out today.

His Measurements

First, let’s have a look at Sergi Constance his stats.

Height: Six foot one

Weight: 207 pounds

Body Fat: 5%

Gains Timeline

By looking at one’s gains throughout the years, we’re capable of pinpointing suspicious progress. For example, if someone has steadily gained muscle for a long time, but then all of the sudden packs on a humungous amount of muscle steroid use is likely.

The picture below shows Sergi Constance his transformation. The left part was him in 2010, and the right part was the bodybuilder in 2015. What we can conclude is that throughout these 5-years the bodybuilder didn’t pack on a lot of muscle mass. However, he did burn some body fat, to our estimation, he went from 8% to 5%.

Earlier Days

A question that arises is, did Sergi Constance use steroids before 2010? Unfortunately, we couldn’t find a picture of the bodybuilder this far back. Therefore we can’t determine if Sergi has built muscle with steroids earlier in his career.

The amount of muscle the Spanish athlete had in 2010 is attainable without steroid use, although it isn’t easy and genetics play a big part.

We don’t think the bodybuilder has used any performance-enhancing drugs. Because there are no other transformation pictures, it’s likely Sergi Constance has been this size for many years. Natural bodybuilders make their significant gains in the first few years that they work out. The more years you’ve been lifting, the less impact it will have on your muscle tissue. In other words, newbs can grow muscle at a quicker rate than people who’ve been bodybuilding for a longer time.

Enhanced Vascularity

The one thing that’s noticeable in Constance’s transformation picture is how vascular he is. His veins pop now.

Enhanced vascularity can be a result of steroid use, as some steroids, like Dianabol increase red blood cell production and thin skin.

However, it’s also a likely result of fat-loss. Many bodybuilders don’t get vascular until their body-fat percentage drops below 6%. Sergi went from 8% to 5% in 5-years which is a logical explanation for his improved vascularity.

Trenbolone Shoulders

Some people on bodybuilding forums have pointed out that Sergi Constance his shoulder muscle are exceptionally well developed. Some people even go as far as suggesting that he has ‘tren shoulders’.

Broad and huge shoulders can be the result of using an androgenic bulking steroid such as Trenbolone. That’s because the shoulders have a lot of androgen receptors, which means steroids have can have more effect on the muscles.

In our opinion, Sergi’s traps are entirely in proportion to his body and not that humungous as on typical steroids users. Therefore, we think that his big shoulders are a result of proper training and genetics rather than steroid use.

If he’d taken Trenbolone or a similar product his traps would likely be as impressive as his delts.

Bodybuilding Competitions

Some bodybuilders compete in competitions exclusive to natural bodybuilders. The federations behind such contests often conduct strict drug tests. Therefore if a bodybuilder has recently competed in such an environment the likeliness of steroid use is nihil.

Sergi, however, has only competed with federations that don’t do drug tests, including the NPC and IFBB. Therefore we can’t use any testing records to determine that he’s natural.


We’ve decided on this because the Spanish bodybuilder has not shown any steroid tells between 2010 and 2015. He doesn’t suffer from any side effects such as dry skin, male boobs, roid gut, lousy skin or artificial traps.

Sergi Constance is a big guy, but everyone (with good genetics) can achieve his physique naturally. However, this definitely won’t be easy. As shown it takes years of dedication and hard work.
