When discussing performance enhancement options in fitness and bodybuilding, two terms often emerge: SARMs and steroids. These substances have gained significant attention for their ability to enhance muscle growth and athletic performance, but they differ greatly in their mechanisms, effects, and safety profiles.
SARMs (Selective Androgen Receptor Modulators) offer a potentially safer alternative to traditional anabolic steroids by targeting specific tissues while minimising unwanted side effects. Unlike steroids, which affect multiple systems throughout the body, SARMs work by selectively binding to androgen receptors in muscle and bone tissue, potentially reducing the systemic impact that makes steroids controversial.
Anabolic steroids have a longer history in bodybuilding and sports, with decades of both documented results and well-established risks. These synthetic versions of testosterone have powerful effects on muscle growth and recovery but come with significant concerns about liver toxicity, cardiovascular strain, and hormonal disruption that SARMs aim to address through their more targeted approach.
Quick Summary
- SARMs selectively target muscle and bone tissues, while steroids affect multiple body systems simultaneously.
- Traditional anabolic steroids typically produce more dramatic results but carry greater risk of serious side effects.
- Both substances remain controversial with varying legal status and require careful consideration of health implications.
Understanding the Basics
Before diving into the comparison between SARMs and steroids, it’s crucial to understand what these compounds are and how they function within the human body. Both substances target androgen receptors but do so through different mechanisms, leading to varying effects and potential risks.
What Are SARMs?
Selective Androgen Receptor Modulators (SARMs) are a class of therapeutic compounds that have anabolic properties similar to anabolic steroids but with reduced androgenic properties. First developed in the 1990s, SARMs were initially created to treat muscle-wasting conditions and hormonal disorders.
Unlike traditional anabolic steroids, SARMs selectively bind to androgen receptors in specific tissues, primarily muscle and bone. This selectivity is what makes them appealing to athletes and bodybuilders.
Common types of SARMs include:
- Ostarine (MK-2866) – Often used for lean muscle gains and recovery
- Ligandrol (LGD-4033) – Known for significant strength and mass increases
- Andarine (S4) – Popular for cutting cycles and fat loss
- Testolone (RAD-140) – Regarded for its potent anabolic effects
SARMs are typically taken orally and don’t require injections, making them more accessible to users.
What Are Steroids?
Anabolic steroids, or anabolic-androgenic steroids (AAS), are synthetic derivatives of testosterone. They were first developed in the 1930s to treat hypogonadism, a condition in which the testes don’t produce sufficient testosterone.
These compounds promote protein synthesis within cells, resulting in the buildup of cellular tissue, especially in muscles. Anabolic steroids have both anabolic (muscle-building) and androgenic (masculinising) effects.
Common anabolic steroids include:
- Testosterone (various esters)
- Dianabol (methandrostenolone)
- Trenbolone
- Winstrol (stanozolol)
- Deca-Durabolin (nandrolone decanoate)
Steroids are available in various forms including oral tablets, injectable solutions, patches, creams, and gels. They’re controlled substances in most countries due to their potential for abuse and health risks.
Mechanisms of Action
The primary difference between SARMs and steroids lies in their mechanism of action and tissue selectivity. This distinction has important implications for both efficacy and side effects.
Steroids function by binding to androgen receptors throughout the body indiscriminately. Once bound, they enter the cell nucleus and directly influence DNA, increasing protein synthesis. This non-selective binding affects multiple tissues and organs, including muscles, bones, hair follicles, sebaceous glands, and reproductive organs.
SARMs, in contrast, selectively target androgen receptors primarily in muscle and bone tissue. They have a unique chemical structure that allows them to:
- Bind specifically to certain androgen receptors
- Trigger anabolic effects in muscle and bone
- Minimise activity in organs like prostate, liver, and sebaceous glands
This selective activity theoretically reduces unwanted side effects while maintaining desired muscle-building properties. However, research on long-term effects remains limited compared to steroids.
Comparing Effects and Benefits
Both SARMs and steroids affect the body’s hormonal systems, but they do so through different mechanisms and with varying results. These compounds impact muscle growth, fat distribution, and recovery in distinct ways that athletes and bodybuilders should carefully consider.
Muscle Growth and Strength
SARMs (Selective Androgen Receptor Modulators) target specific androgen receptors primarily in muscle and bone tissue. They typically produce moderate gains in muscle mass and strength compared to steroids. Users might expect a 3-7 kg increase in lean muscle over an 8-12 week cycle.
Research indicates:
- SARMs increase protein synthesis by 30-50%
- They provide less dramatic but more sustainable gains
- Recovery between workouts is improved moderately
Anabolic steroids, by contrast, flood the body with synthetic testosterone or testosterone derivatives. They create significantly larger gains in shorter timeframes, with some users reporting 7-15 kg of muscle gain during similar cycle lengths.
Key steroid effects include:
- Protein synthesis increases up to 200%
- Dramatic strength improvements (sometimes 20-30% on major lifts)
- Enhanced nitrogen retention in muscle tissue
Fat Loss and Body Composition
SARMs demonstrate notable fat-cutting properties while preserving muscle tissue. Many SARMs like Ostarine and Cardarine are specifically valued for their ability to improve body composition without excessive water retention.
SARMs for fat loss typically:
- Reduce body fat by 3-7% during an 8-week cycle
- Maintain or slightly increase lean muscle mass
- Produce minimal water retention
Steroids vary significantly in their fat-loss capabilities. Compounds like Trenbolone and Winstrol excel at creating a dry, hard physique, while others like Dianabol might cause substantial water retention.
| Compound Type | Fat Loss Potential | Water Retention | Muscle Preservation |
|---|---|---|---|
| SARMs | Moderate to Good | Minimal | Very Good |
| Cutting Steroids | Excellent | Low | Excellent |
| Bulking Steroids | Poor to Moderate | High | Excellent |
Bone Density and Recovery
Both SARMs and steroids positively impact bone mineral density, though through different pathways. SARMs selectively bind to bone tissue receptors, stimulating osteoblast activity without the systemic effects of steroids.
SARMs demonstrate:
- Increased bone healing rates by 30-50%
- Reduced recovery time between intense training sessions
- Lower risk of stress fractures in athletes
Anabolic steroids provide more pronounced recovery benefits, with some users reporting:
- 40-60% faster recovery between training sessions
- Significant increases in bone density across all skeletal areas
- Enhanced collagen synthesis for improved joint and tendon strength
Research suggests steroids may initially strengthen bones but could potentially weaken them through long-term suppression of natural hormone production. SARMs generally offer a milder but safer approach to enhancing bone health.
Potential Risks and Side Effects
Both SARMs and steroids carry significant health and legal risks that users should understand fully before considering their use. These substances impact the body differently but share many concerning side effects.
Adverse Effects on Health
SARMs generally have fewer side effects than anabolic steroids, but they still pose serious health risks. Common side effects include testosterone suppression, liver toxicity, and cardiovascular problems.
Steroid Side Effects:
- Cardiovascular Issues: Increased risk of heart attack, stroke, and elevated blood pressure
- Hormonal Imbalance: Gynecomastia (male breast development), testicular atrophy
- Skin Problems: Severe acne, oily skin, hair loss
- Mood Disturbances: Aggression (“roid rage”), mood swings, depression
SARMs Side Effects:
- Liver Damage: Elevated liver enzymes indicating potential toxicity
- Testosterone Suppression: Natural hormone production can decrease
- Vision Problems: Some users report vision issues with specific SARMs
Blood work monitoring is essential for users of either substance. Both can negatively impact cholesterol levels and may increase risk of osteoporosis with long-term use.
Regulatory and Legal Issues
In the UK, anabolic steroids are classified as Class C controlled substances under the Misuse of Drugs Act 1971. This means possession for personal use is legal, but manufacturing, supplying or selling steroids can result in up to 14 years imprisonment.
SARMs exist in a legal grey area in the UK. They are not approved for human consumption and are technically legal only for research purposes. However, they cannot be marketed for human use.
Purchasing these substances often involves navigating murky legal waters. Many products sold online are:
- Mislabelled
- Contaminated
- Not containing the advertised ingredients
- Containing dangerous additives
The lack of regulation means quality control is essentially non-existent for both substances, creating significant health risks beyond their inherent side effects.

Practical Considerations and Usage
When considering performance enhancement options, proper administration methods, recovery protocols, and selection criteria are essential aspects that significantly impact results and health outcomes.
Dosage and Administration
Proper dosing and administration methods vary significantly between SARMs and steroids. This difference affects how these compounds are used in practice.
For SARMs, dosages are typically much lower than steroids. Most SARMs require 5-30mg daily, depending on the specific compound. Ostarine might be taken at 10-25mg daily, while Ligandrol often ranges from 5-10mg daily.
Steroids generally require more complex administration protocols:
- Injectable steroids: Typically administered 1-3 times weekly
- Oral steroids: Usually taken daily, split into multiple doses
- Dosage ranges: Vary widely based on experience and goals
Administration cycles also differ significantly:
- SARMs cycles: Usually 8-12 weeks
- Steroid cycles: Typically 8-16 weeks
Bodybuilders often stack multiple compounds together, but this increases risk. First-time users should start with minimal effective doses and shorter cycles.
Post-Cycle Therapy and Recovery
Post-cycle therapy (PCT) is crucial for helping the body recover natural hormone production after using performance enhancers.
Steroid PCT requirements:
- Typically more intensive due to stronger suppression of natural testosterone
- Often includes SERMs like Nolvadex (tamoxifen) or Clomid (clomiphene)
- HCG may be used to stimulate testicular function
- Duration: Usually 4-6 weeks
SARMs PCT considerations:
- Lighter compounds like Ostarine may require minimal PCT
- Stronger SARMs like RAD140 often need similar PCT to mild steroids
- Over-the-counter options may be sufficient for milder cycles
Support supplements can aid recovery for both:
- NAC (N-Acetyl Cysteine) for liver support
- Fish oil for lipid balance
- Cardiovascular supplements for heart health
Blood work before, during and after cycles is essential to monitor health markers and ensure proper recovery.
Choosing the Right Option
Selecting between SARMs and steroids should be based on individual goals, risk tolerance and experience level.
For beginners:
- SARMs generally offer a milder introduction to performance enhancement
- Lower risk of severe side effects
- Less complex administration and recovery protocols
- Better option for those concerned about tissue-selective effects
For competitive athletes:
- Both substances are prohibited in most sports
- Testing detection periods vary (steroids: weeks to months; SARMs: days to weeks)
- Risk vs. reward must be carefully evaluated
For TRT patients:
- Medically supervised testosterone replacement therapy differs from recreational use
- Some may consider SARMs as adjuncts to prescribed TRT
- Should always consult physicians before combining approaches
Decision factors should include health history, age, specific fitness goals and legal considerations. Research compounds thoroughly before use, as quality and purity vary widely in unregulated markets.
Frequently Asked Questions
People often have specific questions about SARMs and steroids regarding their mechanisms, safety profiles, and effectiveness. These compounds differ significantly in how they work and their potential side effects.
What are the primary differences in the mechanisms of action between SARMs and anabolic steroids?
SARMs (Selective Androgen Receptor Modulators) bind selectively to androgen receptors in muscle and bone tissue. This selective targeting allows them to promote anabolic effects without significantly affecting other tissues.
Anabolic steroids, conversely, bind to androgen receptors throughout the body. They affect not only muscle tissue but also organs, skin, hair follicles, and the cardiovascular system, which explains their broader range of side effects.
The molecular structure of SARMs allows them to be tissue-selective, while traditional steroids create systemic effects due to their non-selective binding properties.
Can SARMs be safely utilised as an alternative to steroids for muscle building without causing liver damage?
SARMs generally show reduced hepatotoxicity compared to oral anabolic steroids. Research indicates most SARMs do not require liver metabolism through the “first pass” process that makes oral steroids particularly harmful to the liver.
However, SARMs are not completely free from liver concerns. Compounds like RAD-140 and LGD-4033 have shown elevated liver enzymes in some users, particularly at higher doses or with extended use.
Clinical trials remain limited, and long-term safety data is insufficient to declare SARMs completely safe alternatives for liver health. Regular blood work is advised for any SARM user.
What are the potential side effects associated with long-term SARM usage in females, particularly Ostarine?
Females using Ostarine may experience hormonal disruptions, including menstrual irregularities and potential virilisation effects. These can include deepening voice, facial hair growth, and clitoral enlargement, though typically less severe than with anabolic steroids.
Ostarine can suppress natural testosterone production, which may affect female hormone balance despite women having lower testosterone levels. This disruption can impact mood, libido, and energy levels.
Long-term use raises concerns about potential effects on fertility and reproductive health, though research in this area remains limited for female users.
How do the results and side effects of using SARM MK-677 compare with traditional anabolic steroids?
MK-677 (Ibutamoren) technically isn’t a SARM but a growth hormone secretagogue. It stimulates growth hormone and IGF-1 production, offering benefits in muscle growth, recovery, and fat loss, but typically less dramatic than anabolic steroids.
Side effects of MK-677 include increased appetite, water retention, temporary insulin resistance, and potential numbness in extremities. These differ from steroid side effects, which include cardiovascular strain, testicular atrophy, and more severe hormonal imbalances.
MK-677 doesn’t suppress testosterone, unlike steroids, making post-cycle therapy unnecessary. However, it may affect blood glucose levels and insulin sensitivity.
Does the utilisation of SARMs carry a risk of promoting hair loss similarly to anabolic steroids?
SARMs generally pose a reduced risk of hair loss compared to most anabolic steroids. Their selective action means they typically have less impact on scalp DHT levels, the primary hormone responsible for male pattern baldness.
Individual genetic predisposition to androgenic alopecia remains the key factor in determining hair loss risk with any compound. Those with strong family histories of male pattern baldness may still experience accelerated hair thinning with certain SARMs.
Compounds like RAD-140 and S-23 appear more likely to contribute to hair loss than others like Ostarine (MK-2866), which is considered one of the milder options regarding hair loss potential.
To what extent does RAD 140 differ from steroids in terms of efficacy and safety profiles?
RAD-140 (Testolone) demonstrates significant anabolic activity with a 90:1 anabolic-to-androgenic ratio, theoretically offering muscle-building effects with fewer androgenic side effects than testosterone.
Clinical research shows RAD-140 produces measurable lean muscle gains, though typically less dramatic than powerful steroids like trenbolone or dianabol. Users report 3-5 kg of lean mass gain during an 8-week cycle at research dosages.
RAD-140 still causes testosterone suppression requiring post-cycle therapy, despite being marketed as “safer.” It also may impact cholesterol levels and liver enzymes, though preliminary research suggests these effects are less severe than with traditional oral steroids.
