A lot of our readers have requested us to do a steroid analysis for the famous Rocky Actor, therefore today we’re researching if Sylvester Stallone has used anabolic steroids.

Firstly, I’d like to mention that other blogs already have accused Sylvester of using Human Growth Hormone amongst other performance-enhancing drugs, however, we’re going to do our own research on the topic.

Nobody can deny that Sylvester Stallone had an amazing physique throughout his career. Rocky and Rambo have inspired thousands to hit the gym and start working on their bodies. This also explains the great interest in Stallone’s possible help from steroids.

Sylvester Stallone Stats

Let’s start by looking at Mr Stallone his stats and measurements in his Rambo days.

Height: 5”5

Weight: 163-180 pounds

Body fat percentage: 4-8 percent

Chest size: 50 inches

Waist size: 30 inches

Arm size: 17 inches

When we look at these measurements we must state that they’re attainable by natural bodybuilders that have good genetics. Of course, this doesn’t mean that he has not used steroids. However, one thing is clear, in order to build such a physique a lot of work is required for which we have to give probs to Sylvester.

The most prominent aspect of Sylvester physique is his muscle tone, he definitely had the shrink wrap effect going for him. Let there be no misunderstanding, cutting steroids do help achieve this look easier.

Time to dig into the main question: Are Sylvester Stallone his gains natural or did he have some help from steroids?

His Gains Throughout the Years

The best way to determine if someone has used anabolic steroids is to look at their muscle development throughout the years. When someone has built a suspicious amount of muscle in a short period of time or if typical steroid symptoms such as Gynecomastia suddenly appear a case for steroid use can be made. In other words, natural bodybuilders progress in a relatively slow manner compared to steroid users who often suddenly start packing on pounds of muscle.

’75 – Farewell My Lovely

If we look at Sylver Stallone at the beginning of his career we notice that he’s already in great shape and nothing suspicious is going on.

’76 – Rocky

This movie was his big breakthrough and introduced Stallone to the general public. His physique hadn’t really changed, his muscle mass and fat percentage seemed to be pretty much similar. This physique is easily attainable by lifting regularly, so the chances that he has used any steroids here are nihil. His physique didn’t change much for  Rocky 2 as well.

’82 – Rocky 3

Fast forward six years to Rocky 3 and we see a somewhat more shredded Sylvester. We estimate that his fat percentage dropped from about ten percent to eight percent. Due to this weight-loss, this Rocky has better abs and vascularity. He definitely got a fitter physique at this point, but nothing raises a red flag.

’85 – Rocky 4

10 years after Farewell my lovely we see Sylvester Stallone in better shape than ever before. In the 3 years since Rocky 3, the actor has made some serious gains, his muscles appear much fuller and more defined. At this time Sylvester weighed 163 pounds, so he had become super lean for this movie.

We estimate that he reduced his body-fat percentage from around eight percent to four percent for this movie. In the low single digits, every percentage will drastically change your appearance. At this point, Rocky could’ve participated in a bodybuilding competition.

It’s worth mentioning that his cutting progress could’ve been naturally given the three-year time frame. However, it’s questionable.

Sylvester Stallone is known to have hired former Mr Olympia Franco Columbo to help him get in shape for this movie. It’s common knowledge that during this era well-known bodybuilders such as Franco, Schwarzenegger and Ferrigno used steroids to build their signature physiques.

If we look at pictures from both Sylvester Stallone and his trainer during the 70’s we notice that they share a similarity, namely flushed skin. This is a common effect of cutting steroids such as Clenbuterol.

This raises a question, did Franco put Rocky on cutting steroids? We think that’s a likely possibility.

’88 – Rambo 3

At this time Stallone was 42 and he looked better than ever! Playing the legendary character Rambo Sylvester had even fuller muscles than before and appeared to be even more cut.

Something else that’s definitely noticeable is that his skin turned even more flushed as during Rocky 4, which contributes to the idea that the actor had started taking cutting steroids.

’93 – Demolition Man

It’s 1993 and our favourite action movie actor stars in the blockbuster Demolition Man together with Wesley Snipes. In this movie Sylvester Stallone doesn’t look “just fit”, he looks like an absolute beast! Since Rambo, he has made enormous muscle gains, which raises another flag.

The thing is, people are able to pack on the most significant amount of muscle mass in the first few years of lifting, because of the new stimulus the muscles experience. Significant gains during a later stage of a bodybuilders life often are the result of steroid use, especially if they’re as significant as those of Sylvester.

On the other hand, say Sylvester had taken a bulking steroid such as Dianabol then he would’ve probably become even bigger and less defined. So my first guess is that he has taken steroids which help to pack on lean muscle mass, such as HGH.

And that’s not everything, there are more signs that he has used HGH.

HGH Symptoms

After appearing in Demolition Man Stallone acted in several more movies including Rocky and Rambo spins-offs and TheExpendables. At this time the actor was 60 and still was in great shape! But the case for HGH usage got stronger, his waist had become bigger and the actor appeared to be somewhat bloated, which are common HGH effects. Additionally, his head appeared to bigger and not due to a bad diet, because he was still in great shape. This also points towards HGH use.

In ’08 NBC interviewed Sylvester Stallone and he admitted to using HGH after being arrested with nearly 50 bottles of HGH during travels. Sylvester goes on to deny having used HGH for bodybuilding purposes, which we find questionable. However, there’s one thing we do agree on, he mentions that HGH is not going to get you in shape, it’s years and years of training that does. This is 100% true, but we can’t deny that HGH does help in the process of getting more muscular.

So Did Sylvester Stallone use Steroids?

It’s clear that Stallone has used HGH, although he claims to have used it for different purposes than bodybuilding, which many people find hard to believe. Human Growth Hormone use could’ve played a big part in building his physique later during his career.

Furthermore, we think he may have used Clenbutrol around the time Rocky 4 came out due to his very cut and dry appearance at the time.

To conclude, this actor might’ve had some help from performance-enhancing drugs such as HGH and Clenbutrol. Both products help bodybuilders pack on lease muscle mass and get shredded. However, we must give him huge props for being in such great shape throughout his career and at his current age. People all over the world use these products, but not often they look as fit as Sylvester.
