When Shia LaBeouf stepped into the ring for his latest role in the boxing drama “Salvable,” he did more than just act — he transformed physically, adding a staggering 25kg to his frame.
But behind the dramatic body change lies a troubling truth: the use of selective androgen receptor modulators, or SARMs.
In a rare candid moment, LaBeouf admitted to using these controversial substances, bringing Hollywood’s steroid culture into the spotlight once again.
His transparency brings much-needed attention to the extreme methods celebrities use to meet unrealistic physique standards — and the very real dangers that can come with it.
Let’s break down what his confession means, why it matters, and the risks that surround SARMs and rapid body transformations.

Shia LaBeouf’s 25kg Weight Gain: Breaking Down the Transformation
To convincingly portray a fighter in “Salvable,” LaBeouf went from 75kg to just under 100kg — a gain of over 55 pounds. He accomplished this in weeks, not months, relying on SARMs to accelerate muscle growth and physical size.
“I was on all kinds of weird steroids, called SARMs,” LaBeouf admitted during a press event. “Some weird new steroid they gave me so that I got big.”
The actor also revealed the toll it took on his health. “They told me I was about to die. I had a cardiologist tell me, ‘You’ve got to stop.’”
What Are SARMs — and Are They Safer Than Steroids?
Selective androgen receptor modulators (SARMs) are often marketed as a “safer” alternative to anabolic steroids, but their safety profile remains highly questionable.
Unlike traditional steroids, SARMs target specific tissues, like muscles and bones, with the goal of minimizing side effects elsewhere in the body.
However, experts have raised serious concerns:
- Hormonal suppression: SARMs can significantly reduce your body’s natural testosterone production.
- Fertility issues: Reduced sperm count and libido are commonly reported side effects.
- Liver toxicity: Some SARMs are metabolized by the liver and may cause long-term damage.
- Cardiovascular risks: Increased risk of heart attack and strokes has been observed in early research.
- Mood disorders: Users have documented episodes of aggression, depression, and anxiety.
According to a comprehensive review published in the journal Drug Testing and Analysis, the majority of SARMs circulating online are either mislabelled or contaminated, making their use even riskier.
Gaining Mass Fast: The Problem With Radical Transformations
Rapid weight gain, especially when aiming for a muscular physique, is almost never a purely healthy endeavor. While LaBeouf didn’t claim his entire 25kg gain was lean muscle, his approach to nutrition also came into question.
“I had to eat a lot,” he admitted. But once filming ended, the excess weight was no longer sustainable. “I stopped doing SARMs and then stopped eating.”
In a matter of months, he dropped back down to his starting point at 75kg, stating, “I was 220 pounds, and now I’m 165 pounds.”
Such dramatic shifts in weight — especially when assisted by hormone-altering substances — can strain the heart, destabilize metabolism, and damage organ function.
Why Shia’s Honesty Matters
For years, Hollywood actors have been the subject of steroid rumors — often brushed off with claims of extreme training and super-strict diets. Few stars publicly acknowledge the truth. LaBeouf’s admission breaks that trend.
His comment, “I’m so tiny, so small,” underscores the psychological pressure actors face when preparing for physically demanding roles. For someone in the spotlight, particularly in physically imposing roles, the pressure to deliver a certain on-screen appearance can lead to extreme decisions with real-life consequences.
Men’s Health UK praised LaBeouf’s openness, stating that honesty like his “shouldn’t encourage others to follow suit; instead, it should underline that similar transformations aren’t always achievable without drugs.”
Hollywood’s Growing Transparency Around Performance Enhancers
LaBeouf isn’t the only actor who’s recently lifted the curtain on performance-enhancing drug use. In a separate interview, actor Frank Grillo bluntly said: “None of those are natural bodies… We all know what they’re doing. Everybody.”
He highlighted the rising normalcy of testosterone replacement therapy (TRT) in entertainment, adding that many actors take prescribed steroids to achieve short-term muscle gains for roles.
As more celebrities speak out, the conversation is shifting. The long-standing narrative that any physique is achievable with just hard work is being challenged, offering a more realistic — and hopefully more responsible — view of fitness goals.
Takeaways for Everyday Lifters
If you’re looking to build muscle or improve your physique, LaBeouf’s transformation shouldn’t serve as a benchmark or goalpost. Instead, it should be seen as a cautionary tale.
Here are safe, sustainable alternatives to shortcut culture:
1. Prioritize Progressive Overload
Steady strength gains over time are far more effective — and healthier — than rapid bulking through substances.
2. Dial In Your Nutrition
Focus on whole, nutrient-dense foods rich in protein, healthy fats, and complex carbs. Gaining weight should support muscle growth, not just scale numbers.
3. Be Patient With Your Progress
Real, lasting muscle takes time — often years. Set short-term goals and track improvements over weeks, not days.
Ultimately, shortcuts like SARMs and steroids come with significant risks and often temporary rewards.
Final Thoughts: Honesty Over Hype
LaBeouf’s story resonates not because of his dramatic transformation, but because of his candid reflection. He emphasized that even with chemical support, the stress, side effects, and health complications made it unsustainable.
By speaking openly about the measures he took — and the damage they caused — he’s helped dismantle the illusion that visible results are always healthy ones.
It’s a timely reminder that in fitness, as in life, integrity lasts longer than aesthetics. Your health isn’t worth sacrificing for someone else’s ideal body standard — or even your own, if it’s based on unrealistic comparisons.
