But is this true? Is Jeff Seid on juice?

Is Jeff Seid Natty?

Whenever you are looking at whether or not someone is natural, there are a lot of things to consider. First, let’s look at how this person actually looks.

Jeff Seid - Is he on Steroids?
Figure 1: Jeff Seid flexing in a gym

Jeff is obviously a really ripped and aesthetic person. There is no doubt that he does work hard, he diets, and he does put in the work. So, are there signs we should look out for to see if someone is on gear?

  • Massive change in muscularity over a short time period. This will also usually coincide with a drop in body fat and the person tends to get a lot stronger and more confident as well
  • Acne development particularly on the back
  • Hair loss but this can also happen due to aging. That said, Steroids do accelerate hair loss
  • Visual pinning sites are very hard to notice, but sometimes a bad shot will leave a bit of inflammation on the shoulders, buttocks, or other pinning sites
  • Ability to stay in condition for a long time much easier than others. Those on Steroids can stay leaner and muscular for longer and at an easier pace than the rest of us

Technically, Jeff Seid does not really ‘hit’ any of these symptoms or signs… So, does that mean he is natty? Perhaps not…

  • He is incredibly muscular for someone who is ‘natural’. He is quite tall and has a massive amount of muscle for someone that tall. Is this possible natural? Probably not…
  • He stays in great condition for a long time which is almost impossible for a natural person. To retain that amount of muscle mass while remaining quite lean is not only hard but downright unhealthy
  • He makes money off how he looks which is a bit of a copout, but when your livelihood depends on your looks, you probably will end up doing anything and everything you can to keep making money

Which Steroids does (Person) take? 

First off, we have no proof of Jeff actually using Steroids. He has not admitted using them, so, we are not about to make a claim that he has been using them… That said, if we were to guess which Steroids Jeff would be using, it’d be the following:

  • Testosterone as the base of his cycle
  • Masteron or Primobolan as a means to increase muscle size, strength, and vascularity without gaining fat
  • Anavar or Winstrol prior to events or photoshoots to help him gain fullness
  • HGH because everyone in the fitness industry (and sports) uses HGH
  • (Perhaps) Trenbolone when he was at his biggest and most ripped. Trenbolone is known to make people a lot bigger, leaner, and stronger

Why do we think Jeff Seid is Not Natty

Jeff Seid has changed the face of the fitness world, and while there are some that do not like him, the fact remains he has impacted many people positively. Even if he wasn’t natural, he’s done good. But, why do we even think he is taking Steroids?

  • He remains incredibly lean year round
  • He is quite large for someone as tall as he is
  • He is incredibly vascular and carries way more muscle than the average human being
  • He is also able to retain his muscle mass without lifting stupidly heavy

How to see if someone is using Steroids?

How do you know if someone is using Steroids? How do you know if your boyfriend is using Steroids? Here are 5 things to look out for:

  • A sudden change in muscularity or fat mass
  • A sudden change in emotional state, often the results will show themselves as being slightly less patient
  • Hair loss, acne, and other androgenic side effects
  • Obvious signs of injection, like a swollen shoulder
  • Great increase in strength without the addition of fat mass

Jeff Seid Workout & Diet Plan

Let’s be honest, Jeff Seid has been out of the fitness world for quite some time, and finding current content on him is really hard… That said, here are some things we found out about his training:

  • Jeff Seid prefers a Bro-Split training style
  • Just like other bodybuilders, Jeff also uses various types of equipment and training styles
  • His diet is incredibly simple and he prefers natural and healthy food over processed ones

Conclusion: Is Jeff Seid Natty?

Probably not… There are a bunch of signs that show that he is natural, however, the overwhelming size and shape he brings makes you believe he certainly is not natty.

Jeff just remains in too-good-of-a condition year round, and even when he blows up (see above) he still doesn’t look that fat… He looks jacked.

Is Jeff certainly on gear? We’ll never know for sure, but we’re guessing he probably is.
