Selective Androgen Receptor Modulators (SARMs) have become increasingly popular in the fitness and bodybuilding communities due to their ability to enhance muscle growth, fat loss, and improve performance with fewer side effects compared to anabolic steroids. However, while SARMs promise quick results, they remain largely unregulated and their long-term safety is still unknown. In this blog, we’ll take a closer look at the most commonly used SARMs, their benefits, potential side effects, and why they’re so popular among athletes and bodybuilders.
What Are SARMs?
SARMs are synthetic compounds designed to selectively target androgen receptors in specific tissues, such as muscles and bones. When SARMs bind to these receptors, they stimulate anabolic processes that promote muscle growth and bone density. Unlike anabolic steroids, which affect androgen receptors throughout the body, SARMs are designed to specifically target muscle and bone tissue, potentially reducing the risk of side effects such as liver damage, heart disease, and hair loss.
Although SARMs are popular among bodybuilders and athletes looking to enhance their physical performance, they are not approved for general use or medical purposes in many countries, including Australia. In Australia, SARMs are classified as prescription-only substances, meaning they can only be legally obtained through a prescription from a doctor.
The Most Common Types of SARMs
1. Ostarine (MK-2866)
Ostarine is one of the most well-known and widely used SARMs in the fitness community. It is primarily used for muscle preservation and fat loss. Ostarine is often seen as a more beginner-friendly SARM due to its relatively mild effects compared to stronger SARMs.
Uses and Benefits:
Ostarine helps increase lean muscle mass while simultaneously promoting fat loss, making it popular for both bulking and cutting cycles. It’s often used by athletes and bodybuilders who want to improve their muscle definition without putting on significant weight.
Popular Among:
Athletes and bodybuilders who want to build muscle while minimising fat gain, or those in need of maintaining muscle during a cutting phase.
Side Effects:
Although it’s considered one of the safest SARMs, Ostarine can still cause testosterone suppression. Users may experience mild side effects like headaches, joint pain, or nausea, but these are generally less severe than those of anabolic steroids.
2. Ligandrol (LGD-4033)
Ligandrol is known for its potent anabolic effects and is often used by individuals looking for significant muscle gains. It’s considered one of the more powerful SARMs available on the market.
Uses and Benefits:
Ligandrol is primarily used for promoting muscle growth and increasing strength. It can be particularly useful for those looking to bulk up or gain strength quickly.
Popular Among:
Bodybuilders and athletes who want to pack on muscle mass and strength during a bulking phase.
Side Effects:
Ligandrol can cause side effects such as water retention, increased appetite, and testosterone suppression. Users may experience a decrease in natural testosterone production, which could lead to the need for post-cycle therapy (PCT).
3. Andarine (S4)
Andarine, often referred to as S4, is a unique SARM with both fat-burning and muscle-preserving properties. It’s commonly used during cutting cycles for fat loss while maintaining lean muscle mass.
Uses and Benefits:
Andarine is favored for its ability to promote fat loss while enhancing muscle definition. It also boosts endurance, making it a popular choice for athletes who want to improve performance without sacrificing muscle mass.
Popular Among:
Bodybuilders and fitness enthusiasts who are in the cutting phase and want to retain muscle while shedding fat.
Side Effects:
Andarine is known to cause visual disturbances, which may include a yellow tint to vision or reduced night vision. Other side effects can include mild testosterone suppression, fatigue, and joint pain.
4. RAD140 (Testolone)
RAD140, also known as Testolone, is one of the most potent SARMs available, known for its powerful anabolic effects. It is particularly effective in boosting muscle size, strength, and endurance.
Uses and Benefits:
RAD140 is popular for its muscle-building capabilities, often producing rapid gains in muscle mass and strength. It’s commonly used by athletes looking to improve endurance and increase strength.
Popular Among:
Bodybuilders and athletes looking for enhanced performance, muscle growth, and strength gains.
Side Effects:
Like other SARMs, RAD140 can suppress testosterone production. Other potential side effects include increased aggression, irritability, and potential liver strain if used for prolonged periods.
5. Cardarine (GW-501516)
Although not technically a SARM, Cardarine is often included in discussions about SARMs due to its popularity and similar effects. It’s a PPARδ receptor agonist that’s primarily used to boost endurance and promote fat loss.
Uses and Benefits:
Cardarine is commonly used for its ability to increase stamina, endurance, and fat loss. It’s often included in cutting cycles to help athletes improve their cardiovascular performance and burn fat more effectively.
Popular Among:
Endurance athletes and individuals looking to lose fat while preserving muscle mass.
Side Effects:
Cardarine has raised concerns due to animal studies showing a potential link to cancer with long-term use. While the evidence in humans is still inconclusive, it’s important to exercise caution with this substance.
6. MK-677 (Ibutamoren)
MK-677, often referred to as Ibutamoren, is not technically a SARM but a growth hormone secretagogue. It’s used to increase the release of growth hormone and insulin-like growth factor 1 (IGF-1).
Uses and Benefits:
MK-677 is often used to promote muscle growth, improve fat loss, and provide anti-aging benefits. It’s particularly beneficial for improving muscle mass and recovery while promoting overall well-being.
Popular Among:
Individuals looking for anti-aging benefits or those wanting to improve muscle mass and recovery.
Side Effects:
MK-677 may cause increased appetite, water retention, and potential insulin resistance. Other side effects include lethargy or fatigue and possible joint pain.
How SARMs Are Used
SARMs are typically used in cycles, often ranging from 6 to 12 weeks, depending on the specific goals of the user. These cycles are designed to maximise muscle growth or fat loss while minimising side effects. Some athletes and bodybuilders stack different SARMs Australia to enhance their effects, but stacking increases the risk of side effects.
Risks and Side Effects of Using SARMs
While SARMs are marketed as having fewer side effects than anabolic steroids, they are still not without risks. Potential side effects include testosterone suppression, liver toxicity, and cardiovascular issues. Additionally, the long-term effects of SARMs are not well-known due to a lack of comprehensive clinical research.
Final Thoughts
SARMs are becoming increasingly popular for muscle growth, fat loss, and performance enhancement, but they come with both potential benefits and significant risks. Understanding the different types of SARMs, their effects, and potential side effects is crucial for anyone considering their use. While SARMs may offer quicker results compared to other supplements or methods, users should be aware of the legal, health, and ethical concerns surrounding them. Always consult with a healthcare professional before using any performance-enhancing substance.
