Psychological Impact Analysis

What this page covers

The psychological side of performance drugs gets less attention than muscle and blood work, though it shapes who starts using and why some people find it hard to stop. This overview covers what research and user reports say about it for anabolic steroids and SARMs, with peptides compared wherever data exist.

Two related pages go deeper. Our page on muscle dysmorphia and performance drugs covers body image in detail, and the comparison of mood effects by drug class covers what each class does to mood through its pharmacology.

Why people start

Most people who use these drugs aren't competitive athletes. A 2014 meta-analysis of 187 studies estimated the global lifetime prevalence of steroid use at 3.3%, with 6.4% for men and 1.6% for women. A 2019 review in the Journal of Clinical Endocrinology & Metabolism concluded that most users are non-athlete young men who want to look leaner and more muscular.

Surveys of users point the same way. In the UK's 2016 national IPEDinfo survey, 56% of participants rated aesthetic reasons (changing their body image) as a very important motivation. Non-competitive bodybuilding came next at 45%. Among those who injected, two in five combined steroids with peptides or growth hormone.

Speed matters too. A 2017 survey of 800 young exercisers and amateur athletes in five European countries found that almost one in five had used a controlled performance or appearance drug. The reason they gave most often was getting the results they wanted faster. People who abstained most often cited worry about health effects, or wanting to see what they could achieve naturally.

Body image and muscle dysmorphia

Muscle dysmorphia is a preoccupation with being too small or not muscular enough, often in people who are already very muscular. Harvard psychiatrist Harrison Pope and colleagues proposed the term in 1997. They described men and women whose preoccupation caused severe distress and disrupted work and social life, and who often misused steroids. Since 2013 the DSM-5 has listed it as a specifier of body dysmorphic disorder, according to a 2025 clinical review in The Lancet Child & Adolescent Health.

The link with steroids keeps turning up. In a 2006 study of 89 men who lifted weights regularly, steroid users differed little from non-users on most measures but had more muscle dysmorphia symptoms, such as avoiding being seen in public because of how they looked. Short-term users looked much like non-users, while long-term users showed marked symptoms. A 2025 meta-analysis of ten studies found higher muscle dysmorphia scores in steroid users than in non-users, a moderate difference (Cohen's d of about 0.45).

These studies took a snapshot at one point in time, so they can't show which comes first. Muscle dysmorphia may push people toward steroids, or steroid use may feed the preoccupation. The 2006 authors called a causal role plausible but untested.

As of October 2026, we found no study that measured muscle dysmorphia in SARM or peptide users. The 2025 review treats muscle dysmorphia as a risk factor for using steroids and related substances such as SARMs, which are easy to buy online without a prescription. It names cognitive behavioural therapy as the main treatment, adapted from body dysmorphic disorder, and notes that drug treatments have barely been tested in muscle dysmorphia itself.

Mood, withdrawal and dependence

Steroids act directly on androgen receptors in the brain. In a 2000 placebo-controlled trial of 56 men, high-dose testosterone raised manic symptom scores, though most men showed little change and only 8 of 50 at the top dose became hypomanic. SARMs bind the same receptor but have far less mood data, and most peptides work through other pathways.

The stronger evidence concerns what happens after stopping. Steroids suppress the body's own testosterone production. In a 2015 study of 24 former long-term steroid users, 7 (29%) had a major depressive episode during withdrawal, and 4 of them never had one at any other time. Five untreated former users still had testosterone below 200 ng/dL after 3-26 months off.

A 2010 review by the same Harvard group described several routes into steroid dependence. People with muscle dysmorphia may come to rely on the drugs for their effect on muscle. Low mood from suppressed hormones after stopping can push people to restart. The drugs may also be rewarding in their own right: in animal studies, the opioid blocker naltrexone blocked steroid dependence.

Dependence is common among steroid users. A 2023 meta-analysis of 18 studies covering 1,782 users put lifetime androgen dependence at 34.4%, or about one in three. Men and women had similar rates.

SARMs have almost no formal data here. In a survey of 343 SARM users recruited through Reddit, published in 2021, more than half reported side effects such as mood swings and acne. Over 90% of the men still said their muscle mass increased and they were satisfied. The sample was self-selected and the survey didn't measure dependence, and we found no study that did.

For research peptides such as BPC-157 or the growth hormone secretagogues, we found no study of dependence or post-use mood as of October 2026. They don't act on the androgen receptor, so the withdrawal route described above isn't expected to apply. That's an inference from mechanism, not a measured result.

The psychology of chasing results

Social media is the best-studied pressure. In a 2024 survey of 1,553 boys and men in Canada and the US, those who more often viewed content about muscular bodies or muscle-building drugs were more likely to have probable muscle dysmorphia. That held regardless of total screen time, though a snapshot can't show which way the effect runs.

An experiment gets closer to cause. In a 2026 Australian study, 282 men aged 17 to 30 were randomly assigned to watch idealized fitness or supplement videos on TikTok, or travel videos as a control. The idealized content lowered their satisfaction with their own diet and raised their intention to use creatine. In men with a stronger drive for muscularity, it also shifted intentions to use steroids. Comparing their own appearance with others' explained the effects.

Peptides have their own version of this. A 2024 study of a large UK fitness forum (493 threads, almost 15,000 posts) found people turning to peptides mainly for injury repair and everyday wellbeing, often older men returning to the gym. Some said they tried peptides after feeling let down by doctors or physiotherapists. A significant minority reported no benefit. Experienced members blamed part of that on poor-quality products and part on newcomers expecting a quick cure rather than an aid to recovery.

That expectation gap matters because most performance peptides have never been tested for muscle gain in people, as our comparison of peptides with traditional anabolics explains. According to University of Queensland researchers, peptide content had passed 130,000 Instagram posts and 230 million TikTok views as of May 2026. They argue that influencer marketing normalizes use while making the risks look smaller.

How the classes compare

Physical side effects and legal status are covered on the main hub comparing peptides with steroids and SARMs.

What we still don't know

Almost all of this evidence is cross-sectional or self-reported. Only studies that follow people from before they start using could show whether body image problems lead to drug use or the reverse, and few exist.

The only SARM user survey we found was recruited through Reddit, and peptide users have been studied mostly through forum posts. Nobody has measured muscle dysmorphia or dependence in peptide users. In June 2026, the researchers quoted by the University of Queensland called for more work on how and why people use peptides.
