SARMs are frequently presented online as a safer and more modern alternative to anabolic steroids. Videos and advertisements may promise increased muscle, improved strength and faster physical transformation—with fewer unwanted effects.
However, the reality is much more complicated.
SARMs are not simply “mild steroids”, and products sold online may not have been approved for human use. Before believing claims made by influencers or supplement sellers, it is important to understand what SARMs are, how they differ from anabolic steroids and what health risks may be involved.
This guide offers an impartial overview based on information from recognised health and anti-doping organisations.
What are anabolic steroids?
Anabolic-androgenic steroids are manufactured substances that produce effects similar to testosterone. The word “anabolic” refers to tissue and muscle building, while “androgenic” describes the development of male characteristics.
Some anabolic steroids have legitimate medical uses and may be prescribed under professional supervision. Non-medical use usually involves taking them to increase muscle mass, strength or athletic performance.
Anabolic steroids should not be confused with corticosteroids, such as prednisolone, which doctors prescribe for inflammatory conditions. Although both are described as steroids, they act differently in the body.
What are SARMs?
SARMs stands for selective androgen receptor modulators. They were initially researched as potential treatments for conditions including osteoporosis and muscle-wasting disorders.
They are designed to interact with androgen receptors, which influence muscle and bone tissue. The word “selective” has contributed to the belief that SARMs only affect particular parts of the body and therefore cause fewer side effects.
That does not mean they are risk-free.
Many SARMs promoted through social media or sold online have not been approved as medicines for bodybuilding or performance enhancement. A label stating “research use only” or “not for human consumption” does not make a product safe to take.
Why are SARMs becoming a major topic?
Social media has made performance-enhancing substances considerably more visible. Transformation videos, gym content and influencer promotions can make SARMs appear similar to ordinary sports supplements.
In May 2026, a UK Anti-Doping survey of 1,043 people aged 16 to 25 found that 33% reported buying SARMs online at some point after seeing them promoted or advertised on social media. UKAD also reported that 29% had seen SARM-related social content at least once a week during the previous 30 days.
These figures do not show that a third of every young person in Britain uses SARMs—the findings relate specifically to the people surveyed. They do, however, highlight growing exposure to these products and the importance of accurate information.
Are SARMs safer than anabolic steroids?
There is not enough reliable evidence to describe non-medical SARM use as safe.
SARMs and anabolic steroids are different types of substances, but both can interfere with the body’s hormonal systems. The effects will also depend on the actual substance, the amount taken, duration of use, the person’s health and whether the product contains what its label claims.
Possible risks associated with SARMs include:
Suppression of natural testosterone production
Changes in cholesterol levels
Liver injury
Reduced fertility
Acne or hair loss
Mood or sleep changes
Possible cardiovascular complications
Unknown long-term effects
Products purchased through unregulated sources create an additional concern. Their stated ingredients, purity and strength may not have been independently verified. A consumer may therefore be unable to know exactly what they are taking.
What are the risks of anabolic steroids?
The risks of anabolic steroids are better documented because they have been used and studied for longer.
The NHS guidance on anabolic steroid misuse lists possible physical and psychological effects including reduced sperm count, infertility, erectile dysfunction, hair loss, severe acne, high blood pressure, high cholesterol, liver or kidney problems, mood swings, aggression and paranoia.
Effects differ between individuals, and a person may not notice an internal health problem immediately. Changes involving blood pressure, cholesterol, hormone production or liver function can develop without clear early symptoms.
Does cycling or stacking make steroid use safe?
Two of the most common questions are whether “cycling” or “stacking” can prevent harm.
Cycling means using a substance for a set period before stopping. Steroid stacking means using more than one substance together. Pyramiding involves gradually increasing and then reducing the amount taken.
According to the NHS, there is no evidence that these practices reduce the harms and side effects associated with anabolic steroid misuse. Combining substances may also make adverse effects more difficult to identify.
Are SARMs the same as supplements?
No. A product being available through a website or presented alongside protein powders does not make it an ordinary food supplement.
Supplements generally provide nutritional ingredients such as protein, vitamins or minerals. SARMs act on androgen receptors and may affect natural hormone production. They should not be treated as equivalent to creatine, protein powder or a multivitamin.
Consumers should be particularly cautious when a product:
Promises extremely rapid muscle gain or fat loss
Uses dramatic before-and-after photographs
Relies mainly on influencer testimonials
Does not clearly identify its manufacturer
Makes medical claims without credible evidence
Says “not for human consumption” while promoting physical benefits
Are SARMs permitted in competitive sport?
Athletes should assume that SARMs present a serious anti-doping risk. UK Anti-Doping describes SARMs as image and performance-enhancing drugs, and prohibited substances can result in sanctions even when a product was incorrectly labelled or obtained without understanding its contents.
Competitive athletes remain responsible for substances found in their bodies. A product being described as a “research chemical” does not protect an athlete from an anti-doping violation.
What should someone do if they have used SARMs or steroids?
Anyone experiencing chest pain, difficulty breathing, fainting, severe abdominal pain, yellowing of the skin or eyes, or a serious change in mental health should seek urgent medical assistance.
For non-emergency concerns, speak honestly and confidentially with a GP or qualified healthcare professional. Useful information to share includes:
The name of the product or substance
How long it has been used
Any other medicines or substances involved
Physical or psychological symptoms
Photographs of the packaging or ingredient label
A healthcare professional may recommend an assessment based on the person’s symptoms, health history and potential risks. Medical advice should come from a qualified professional—not an influencer, anonymous forum or seller.
Frequently asked questions Are SARMs a type of steroid?
No. SARMs and anabolic steroids are chemically different, although both affect androgen-related processes and may interfere with hormones.
Can SARMs suppress natural testosterone?
Some SARMs may suppress natural testosterone production. The extent can vary depending on the substance, exposure and individual.
Are online SARM products accurately labelled?
There is no guarantee. Products obtained through unregulated sources may contain different quantities or ingredients from those shown on the label.
Do SARMs have fewer side effects than steroids?
Claims that SARMs are universally safer are not supported by enough high-quality long-term evidence. Different substances have different risks, but “selective” does not mean harmless.
Are anabolic steroids addictive?
The NHS states that anabolic steroids can be addictive. People may continue using them despite physical effects or experience withdrawal symptoms when stopping.
Is information from fitness influencers reliable?
Personal experience is not the same as medical evidence. Influencers may have commercial relationships with sellers and cannot determine how a substance will affect another person.
The bottom line
SARMs are often promoted as a convenient middle ground between supplements and anabolic steroids. That description can create a false sense of security.
Neither popularity nor online availability proves that a product is safe. SARMs may affect hormones, cholesterol, liver health, fertility and psychological wellbeing, while their long-term effects are not fully understood. Products from unregulated sources may also be incorrectly labelled or contaminated.
Anyone considering or already using a performance-enhancing substance should seek confidential advice from a qualified healthcare professional.
