What are SARMs?

SARMs, or Selective Androgen Receptor Modulators, are a class of compounds designed to target and interact with androgen receptors in the body. Androgens are a group of hormones, including testosterone, that play a crucial role in various physiological processes, such as muscle growth, bone density, and the development of secondary sexual characteristics. Unlike anabolic steroids, which often result in widespread androgenic effects, SARMs aim to provide selective targeting. This means they are intended to focus on specific tissues, primarily muscle, and bone, while minimizing the androgenic impact on other parts of the body.

How to Use SARMs

SARMs are available in various forms, including pills, capsules, and liquid solutions. They are typically taken orally, making them convenient for users. The dosages may vary depending on the specific SARM, but it is crucial to follow the manufacturer’s instructions or consult with a healthcare professional to determine the appropriate dosage for your goals. Cycling SARMs, which involves taking them for a set period and then taking a break, is a common practice to prevent potential side effects and maintain the effectiveness of these compounds.

Benefits of SARMs

  1. Muscle Growth: SARMs have gained popularity for their ability to promote muscle growth. They work by binding to androgen receptors in muscle tissues, which can lead to increased protein synthesis and muscle hypertrophy.
  2. Bone Health: Some SARMs have shown promise in enhancing bone density, making them potentially valuable for those dealing with conditions like osteoporosis.
  3. Fat Loss: Certain SARMs may aid in reducing body fat while preserving lean muscle mass. This can be particularly appealing for individuals looking to achieve a lean and toned physique.
  4. Improved Athletic Performance: SARMs can boost endurance and strength, which may be advantageous for athletes and fitness enthusiasts.
  5. Selective Action: Unlike anabolic steroids, SARMs are designed to minimize the androgenic effects on other body tissues, reducing the risk of unwanted side effects.

Side Effects of SARMs

While SARMs are generally considered to be safer than traditional anabolic steroids, they are not entirely free from potential side effects. Some common side effects associated with SARM use may include:

  1. Hormone Imbalance: Even though SARMs are selective, they can still influence hormone levels. This can lead to temporary imbalances, especially in testosterone.
  2. Liver Toxicity: Some SARMs can put a strain on the liver, so monitoring liver health is important during use.
  3. Cardiovascular Risks: Long-term use of SARMs may affect lipid profiles and increase the risk of cardiovascular issues.
  4. Suppression of Natural Testosterone Production: Prolonged use of SARMs can lead to suppression of endogenous testosterone production. Post-cycle therapy (PCT) may be necessary to restore hormonal balance after discontinuing SARMs.

What are SERMs?

SERMs, or Selective Estrogen Receptor Modulators, are a class of compounds that interact with estrogen receptors in the body. Estrogen is a key hormone in both males and females, playing a role in various physiological functions. SERMs have the ability to selectively modulate estrogen activity, which can be beneficial in certain contexts.

Benefits of SERMs

  1. Breast Cancer Treatment: SERMs, like Tamoxifen, have been widely used in the treatment of breast cancer. They work by blocking estrogen receptors in breast tissue, preventing estrogen-driven tumor growth.
  2. Osteoporosis Prevention: Some SERMs can enhance bone density, making them valuable in preventing and treating osteoporosis.
  3. Menopausal Symptom Relief: SERMs are sometimes prescribed to alleviate menopausal symptoms in women, such as hot flashes and vaginal dryness.
  4. PCT After Steroid Use: SERMs like Clomiphene are commonly used during post-cycle therapy to help restore natural testosterone production after a steroid cycle.

Side Effects of SERMs

SERMs are generally well-tolerated, but they may still have potential side effects, including:

  1. Hot Flashes: A common side effect in women, hot flashes can occur with SERM use.
  2. Blood Clots: Some SERMs may increase the risk of blood clot formation, particularly in individuals with a history of clotting disorders.
  3. Uterine Cancer: Long-term use of SERMs may slightly elevate the risk of uterine cancer, so careful monitoring is necessary.
  4. Mood Swings and Depression: Some users may experience mood swings and depression while taking SERMs.

Should I Use SERMs When Using SARMs?

One of the most common questions in the world of performance-enhancing compounds is whether one should use SERMs alongside SARMs. The answer to this question depends on several factors, including the specific SARM being used, the dosage, the duration of use, and the individual’s goals.

SARMs Only

In many cases, individuals using SARMs for short cycles at moderate dosages may not need to use SERMs. SARMs are less likely to suppress natural testosterone production compared to traditional anabolic steroids. However, it is essential to monitor hormone levels and be prepared for the possibility of temporary suppression.

SARMs with SERMs

For more extended SARM cycles or higher dosages, or if an individual is particularly concerned about hormonal imbalances, the addition of SERMs during or after the SARM cycle may be considered. SERMs can help mitigate the potential suppression of natural testosterone production.

It’s crucial to remember that combining these compounds should be approached with caution, and medical supervision is advisable. Regular blood work and consultation with a healthcare professional can provide valuable insights into whether SERMs are necessary for your specific circumstances.


The choice between SARMs and SERMs depends on your fitness goals, health considerations, and individual circumstances. SARMs offer the promise of muscle growth, enhanced athletic performance, and body recomposition, with fewer androgenic side effects than traditional steroids. SERMs, on the other hand, have well-established roles in breast cancer treatment, osteoporosis prevention, and post-cycle therapy after anabolic steroid use.

Before incorporating SARMs, SERMs, or any other performance-enhancing compounds into your regimen, it is crucial to conduct thorough research, consult with a healthcare professional, and prioritize safety. Always be mindful of potential side effects, monitor your health throughout the cycle, and consider post-cycle therapy when necessary.

In the pursuit of physical excellence, education, and informed decision-making are your most potent allies. Remember that health should always be the top priority, and any substance you choose to use should align with your health and fitness goals while minimizing potential risks. Here are some key takeaways to consider when navigating the world of SARMs and SERMs:
