Mood Changes on Steroids: Roid Rage and Real Risks

PED SIDE EFFECTS · MOOD

ROID RAGE: IS IT REAL? WHAT TRIALS AND CRIME DATA ACTUALLY SHOW

Roid rage is the idea that steroids make people aggressive or violent. It is real for some people, but rarer and smaller than the name suggests. In a controlled trial at 600 mg a week, 84% of men showed minimal mood effects (PMID 10665615).

This guide covers mood changes on steroids: aggression, mania, depression after a cycle, and what the violence data mean. For the wider picture, see the PED side effects hub.

What this roid rage guide covers

Covered

Is roid rage real, from randomized trials and large population studies.

Mood changes on steroids: aggression, irritability, mania and depression after stopping.

Who is most at risk and what helps.

Not covered

Corticosteroids. Prednisone mood swings are a different drug class. This page is about anabolic steroids.

A diagnosis. Mood problems need a doctor or mental health professional.

What is roid rage?

Roid rage is a popular name for anger, irritability or violence blamed on anabolic steroids. It is not a medical diagnosis.

Researchers usually measure it as aggression scores, manic symptoms or violent acts. Those are different things, and the data differ for each.

Steroid users often take very high doses, combine several drugs and use other substances. That makes the cause hard to pin down, the Endocrine Society notes (PMID 24423981).

YouWhat this means for you. When someone says roid rage, ask which part: feeling irritable, a manic episode, or actual violence. The evidence is strongest for the first two.

Is roid rage real?

Yes, for some people, and usually mild. A meta analysis of 12 randomized trials in 562 healthy men found steroids raised self reported aggression a little. The effect size was 0.171 (PMID 33745011).

That rise was not seen in observer reported aggression. It also did not show in the analysis of higher doses over 500 mg or longer use (PMID 33745011).

In a 1996 trial, 600 mg of testosterone a week for 10 weeks did not alter mood or behavior in any group (PMID 8637535).

YouWhat this means for you. Is roid rage real? In trials, steroids nudge aggression up slightly on average. A few people react strongly; most do not.

The key roid rage trial: 600 mg a week

In 2000, 56 men took testosterone cypionate rising to 600 mg a week for 6 weeks, and placebo for 6 weeks (PMID 10665615).

Testosterone raised manic scores and aggressive responses on a provocation test (PMID 10665615).

But reactions varied a lot. Of 50 men, 42 had minimal effects, 6 became mildly hypomanic and 2 markedly hypomanic (PMID 10665615).

The 8 men who reacted did not differ at baseline from the 42 who did not. Nothing predicted who would react (PMID 10665615).

YouWhat this means for you. Real world doses are often higher than 600 mg and mixed with other drugs. The trial shows the effect exists but cannot say how big it gets at those doses.

Steroids and violence: what the crime data show

A small link. A meta analysis of 14 studies and 137,055 people found a significant but small link between steroid use and violence, r = 0.21 (PMID 37467456).

Most studies could not show which came first, the steroids or the violence (PMID 37467456).

Other drugs explain much of it. In 10,365 Swedish men, steroid use raised the odds of a violent conviction 5.0 times. After accounting for other drug use, it fell to 1.6 times, not significant (PMID 25170826).

Steroids and violence: drugs explain mostOdds of a violent crime conviction with lifetime steroid use, 10,365 men.Raw odds5.0xAfter other drug use1.6xAdjusted result not significant. PMID 25170826.
Steroids and violence:drugs explain mostOdds of violent crime,10,365 men.Raw odds5.0xAfter other drug use1.6xAdjusted: not significant.PMID 25170826.

But the gap stays in some data. In Denmark, 20.6% of 545 men caught with steroids in gyms already had a prison sentence, vs 3.7% of controls (PMID 31421475).

Over follow up it rose to 29.5% vs 4.9%. The risk stayed high after adjusting for drug abuse and psychiatric illness (PMID 31421475).

In US young adults, steroid users reported more violence even after adjusting for past violence and other drugs (PMID 18923108).

YouWhat this means for you. Steroid users commit more crime on average, and many already did before. Steroids may add to it, but they are rarely the only cause.

Who is most at risk of roid rage?

Dependent users. In 139 weightlifters, men who met dependence criteria reported the most aggression. Antisocial personality traits were an important link (PMID 33621808).

Polydrug users. Other substance use explained most of the violence link in Sweden (PMID 25170826).

High doses and stacks. Users often take far above medical doses and combine drugs, which raises every risk (PMID 24423981).

An unpredictable few. In the trial, nothing at baseline flagged the men who became hypomanic (PMID 10665615).

YouWhat this means for you. Risk climbs with dependence, other drugs and an aggressive baseline. If you already struggle with anger, steroids are a bad match.

Roid rage symptoms and mood changes on steroids

Mood changes reported on and after steroids.
ChangeWhenEvidence
Irritability, short temperOn cycleSmall rise in self reported aggression (PMID 33745011)
Mania or hypomania: less sleep, racing thoughts, grandiosityOn high doses8 of 50 men at 600 mg a week (PMID 10665615)
Feeling good, liking the drugOn cycleHigher drug liking scores (PMID 10665615)

ViolenceRareSmall link, often explained by other drugs (PMID 37467456, 25170826)

People close to you often notice changes before you do. In the trial, partners also kept weekly diaries (PMID 10665615).

YouWhat this means for you. Less sleep, more energy, faster speech and big plans can be early signs of hypomania. Take them seriously.

Depression after a steroid cycle

The bigger mood problem is often after the cycle, not during it.

In 24 former long term users, 7 (29%) had major depression during withdrawal. Four had never had depression before (PMID 25598171).

About 2.5 years after stopping, 24.2% of former users had depressive symptoms, more than controls. 40.1% reported low libido (PMID 27532478).

This tracks with low testosterone after cycles. Former users had lower testosterone than controls years later (PMID 27532478).

YouWhat this means for you. Plan for the end of a cycle as much as the start. See hormonal recovery after steroids and post cycle therapy.

Does TRT cause mood swings?

TRT targets normal testosterone levels, far below cycle doses. See is TRT a steroid.

In 790 men aged 65 or older, testosterone gel raised levels to mid normal for a year. Men reported slightly better mood and fewer depressive symptoms than on placebo (PMID 26886521).

YouWhat this means for you. At replacement doses, mood tends to improve slightly, not worsen. Mood swings on TRT are worth checking against your blood levels. See TRT side effects.

What helps with mood changes on steroids

Read this first

This is not treatment advice. Thoughts of harming yourself or others need urgent help from a doctor or emergency service.

1

Tell someone close

Partners noticed changes in the trial; ask them to say if you seem different (PMID 10665615).

2

Avoid other drugs and alcohol

Other substance use explained most of the violence link (PMID 25170826).

3

Lower the dose or stop

Effects in trials came from high doses; there is no safe roid rage dose for a reactive person (PMID 10665615).

4

Plan the exit

Depression often hits after stopping (PMID 25598171). Talk to a doctor about recovery.

5

Get help for dependence

Dependent users reported the most aggression (PMID 33621808).

YouWhat this means for you. Mood changes on steroids are a reason to reassess, not to push through. See PED side effects and libido on steroids.

Verdict: 5 facts about roid rage

1. It is real but uncommon. 8 of 50 men reacted at 600 mg a week (PMID 10665615).

2. The average effect is small. Aggression effect size 0.171 in 12 trials (PMID 33745011).

3. Violence is mostly about other drugs. Odds fell from 5.0 to 1.6 (PMID 25170826).

4. Dependence raises the risk. Most aggression in dependent users (PMID 33621808).

5. Depression after cycles is common. 29% during withdrawal (PMID 25598171).

Roid rage: frequently asked questions

What is roid rage?

A popular name for anger or aggression blamed on anabolic steroids. Trials show a small average rise in self reported aggression (PMID 33745011).

Is roid rage real?

Yes, for some. At 600 mg a week, 6 of 50 men became mildly and 2 markedly hypomanic; 42 had minimal effects (PMID 10665615).

There is a small link, r = 0.21 across 14 studies (PMID 37467456). In Sweden, other drug use explained most of it (PMID 25170826).

What are roid rage symptoms?

Irritability, short temper, less need for sleep and racing thoughts. These can signal hypomania (PMID 10665615).

Can you get roid rage on TRT?

Unlikely at replacement doses. In 790 older men, testosterone gel slightly improved mood (PMID 26886521).
