Jeff Seid is a 23 year old Men's Physique competitor who made history when he became the youngest pro in IFBB history.

Jeff basically looks like a real-life Goku.

Long, spiky hair, jacked muscles and shredded to the bone. As a result he's become an icon for gym-rats worldwide who covet that ‘aesthetic look'.

These guys have no interest in looking like mass monsters, with 36 inch waists and pregnant-looking belly's.

This aesthetic v-taper look involves having a tiny waist, being shredded and having broad shoulders. This is a look that was originally inspired by ex-Mr Olympia champion – Frank Zane.

Jeff certainly isn't HUGE, but has good size and is ripped to shreds possessing near-perfect proportions.

Jeff's body is the dream-goal for many ectomorphs/hardgainers around the world, who previously idolized Aziz Shavershian aka Zyzz.

If you're familiar with Jeff you'll know that he embraces the YOLO lifestyle to the max. You'll often see videos of him randomly posing in public (with his top off)…

For no actual reason.

And he likes to give off the impression that he pulls more shluts than Barney Stinson.

With over 2 million fans on his Facebook page alone; it's clear that plenty of guys worldwide are ‘mirin Jeff.

However, the general consensus is that Jeff could be taking steroids, with brahs regularly calling him out on social media and even calling him a liar…

So is Jeff really natty? or is he just one boy in a generation that are trying to impress girls, no matter what the cost?

Evidence Jeff is Natty

. Genetics from the Gods

99% of the time when somebody juices, it's obvious because their muscles always blow up in a short space of time.

Adding muscle naturally is a very slow process, thus fast gains simply do not exist…except for when you're a newbie.

Although Jeff is young, he started lifting at 12 years old.

Thus he's been lifting for 9 years.

And from looking at his photos it's clear he hasn't gained much size since he was 17 (see below).

What he Looked Like at 17 Years Old

What does this tell us?

He's got insane genetics when it comes to building muscle and burning fat.

It's not like he was small after the first few years of lifting weights and then blew up all of a sudden…he's more or less the same size compared to when he was a teenager.

In the above picture Jeff was apparently weighing 195lbs at 5% body fat.

Here's Jeff's 9 year transformation from 12-21 years old…

You can see that the biggest jump for Jeff in terms of muscle growth was from 12 to 13 years old.

This makes perfect sense seeing as this was his first year of training, which is when you'll make most of your gains if you're natty.

2. No acne

Jeff admitted once in a interview that before he started lifting weights, he was a nerd addicted to World of Warcraft and suffered from acne.

What's this got to do with him taking steroids?

Many steroid-users experience acne – occurring mostly on the face, back and shoulders.

Other users can run multiple cycles and NEVER experience acne.

Why steroids can cause acne…

Steroids increase your body's androgenic hormones, which in turn stimulates the sebaceous glands to produce more oils.

However, acne from steroid-use is largely genetic. So if you haven't experienced acne growing up, there's a good chance you won't experience any when juicing.

But, if you DID have acne during childhood and you were to run a steroid cycle years later, you'll almost certainly have some breakouts.

However, Jeff's skin remains very clear, natural and consistent looking in all of his pictures. Therefore it's likely he's not taking steroids because his sebaceous glands aren't producing this excess oil that he is genetically prone to.

3. Steroids Are Against His Philosophy

Here's a video of Jeff talking about steroids…It gets good around the 51 minute mark.

So in the video Jeff basically says that he doesn't understand why guys going for that aesthetic look would take steroids, because his belief is that you can naturally get jacked/become aesthetic as fuark.

Makes sense.

However he does mention that he understands steroid-use for those with aspirations to look like Mr Olympia guys, such as Phil Heath and Ronnie Coleman etc. as that's a completely different goal.

Jeff goes on to say that the look and lifestyle he wants is a healthy one, and thus steroids will most certainly compromise that.

It's important to note here that anyone can lie in front of a camera, but he seems very genuine when speaking about this topic.

This is solid advice from Jeff, essentially encouraging young people to go down the natty route.

However, not everybody will have Jeff's world-class genetics.

I know dudes down my gym who are juicing their asses off and don't look half as good as Jeff.

This is because:

  1. They haven't got awesome genetics
  2. They don't have expert knowledge regarding nutrition/training

4. No physical signs of steroid-use

If he were to have juiced, it must've been from a young age…as he's only had small gains since the age of 17.

So if he HAD taken anabolic steroids, there'd be some visual steroid side effects.

…But none can be seen on Jeff.

  • He still has extremely thick hair. Taking steroids for several years would've thinned/receded his hair, especially when taking drugs before finishing puberty.
  • He has no case of gyno.
  • No flushed/red-looking skin, indicating higher body temperature/blood pressure as a result of taking anabolics.
  • Clear skin
  • He still has a baby face. Steroid-users often experience more wrinkles and ageing, because many anabolics decrease the amount of collagen that your body produces. A good example of how much your face can age is Zac Efron when he juiced for Baywatch.
  • No sign of bloat or water retention.


5. The Serge Nubret Comparison


Haters of Jeff Seid are saying there's no way he's natural because he has the same stats as Serge Nubret, one of the best Mr Olympia contestants of all time (who was known to be juicing).

Here's the approximate stats of Nubret and Seid (when competing):

  • Height: 6 foot
  • Weight: 200lbs
  • Body fat: 6%
  • Arm size: 18 inches

Here's the comment:

jeff seid same stats as serge nubret

Even sites like Natty or Not have said the same, stating there's no way Jeff is natural because he shares the same numbers as the black panther.

Anyone who thinks this claim has any credibility whatsoever needs to get their IQ tested.

Serge Nubret was A LOT bigger than Jeff Seid.

End of discussion.

We don't know if those numbers are 100% legit; and even if the stats were accurate – numbers are often deceiving.

What we do know for sure is how big these guys look in pictures and real life and Jeff Seid is nowhere near Serge Nubret, in terms of muscularity.

Verdict: Natty

There's no evidence whatsoever to suggest Jeff is juicing.

The main thing to take away from this analysis is that some people out there have insane genetics.

Many butt-hurt guys are posting stuff like “He's 100% on steroids”, with nothing to back up their claims other than…

“He's in too good shape to not be taking anything”.

The truth is, it's not a level playing field because every man has completely different genetics when it comes to building muscle.

For some guys all they have to do is lay eyes on a pair of dumbbells and they grow. For others they remain beanpoles no matter how hard they train.

Logic of the day: Just because somebody is jacked, doesn't mean they're 100% injecting.

    1. Hey, is it not possible jef seid is on a fat burning steroid cycle like anavar in order to keep his fat levels low as it seems ridiculous even with insane work to have such a shreded physique?
      Also its common belief that all pro bodybuilders use some sort of steroids in the weeks before the competitions otherwise they simply cannot reach such a level. maybe im wrong, perhaps too many uneducated haters out there that spread wrong information.
      super entertaining website !

      • @Erland – Hey, getting shredded naturally isn’t ridiculous – it’s a very attainable goal for pretty much any individual. If you really want to know if someone’s on steroids you have to ignore all “common beliefs” and simply listen to the facts 🙂

    2. “There’s no evidence whatsoever to suggest Jeff is juicing” what about the fact that his FFMI is around 27-28. This indicates that the chance of him actually being natural is very unlikely. There’s different types of steroids not all will make him look like a giant. Using science, it can be determined that there is a good chance he used something to assist him.

      • @Jahe – FFMI is flawed. It’s an outdated and inaccurate way of telling if someone’s on steroids. For 90% of people it’s probably correct, but we’re talking about some of the best physiques on the planet in 2017 – not a bodybuilder from almost 100 years ago (when the FFMI research took place). It’s very possible to build a physique like Jeff Seid naturally. You’d need great genetics, but he’s hardly a freak at 195lbs (6ft tall).

    3. Love you Jeff, I believe Jeff is 100 percent natty. Im with Jeff, and on the road to attain a physique just like him. Dedication, consistency and hardwork… along with a good diet. That’s it, good form… and Jeff does all of that. Stay shredded brah, Ill be up there soon 🙂 Ill prove them all wrong!

    4. I think his physique is definitely attainable for people with similar structures and genetics. Like you mentioned in the video he does have really good genetics for burning fat, he was never fat… And has been lifting since forever. If he is on something it’s gotta be like low dose of test, but I hardly doubt he’s taking anything. Good looking as he is I don’t think he’ll risk his health for bodybuilding when he can make so much more modeling for CK or something with a natural physique. He’s always been placing like dead last at the IFBB shows plus doesn’t look full when he diets down. He has no androgenic signs. It’s easier for me to diagnose this considering I have really good muscle building genes, living, Born and raised in NYC I’ve met lots of people who are users and non users. People say “eww he has stats like serge nubret”, so fucking what… He isn’t serge nubret, the weider Brothers painted a certain picture of serge nubret… Serge nubret was 6ft that means he didn’t take much shit if he was only 6ft,another thing you don’t know how consistent serge was, he probably wasn’t as dedicated as Jeff… No one know this” I hate when someone sees a black men that’s ripped, and because they are another ethnicity they think their level of muscularity isn’t attainable. That’s coming from someone who’s mulatto, I’m bi racial and tired of listening to ignorant, dumb shit.

      • yang, what are you implying? Many guys have gyno and have never taken steroids. Some guys simply get it during puberty and it never goes away.

    5. I used to use this website as a source when showing my friends proof that someone is on steroids, and you seem like a knowledgeable guy, but Jeff seid is 100% on growth hormone or some sort of anabolic. Nobody can achieve a body like that naturally and especially staying at sub digit bodyfat levels for too long decreases testosterone and fucks with your energy levels. You keep calling people butthurt and telling them to look at the facts when you haven’t listed any and you dont even seem to know there are hundreds of steroids out there and they all accomplish different goals, he could very well be taking ibutamoren to look like yoel Romero, having 0 side effects but all the benefits of steroids
