RAD140 Suppresses Endogenous Androgens and Increases Estrogen: What You Need to Know

RAD140, commonly known as Testolone, is a selective androgen receptor modulator (SARM) developed to promote muscle growth and enhance performance. Its high affinity for androgen receptors in muscle and bone tissues makes it a popular choice among athletes and bodybuilders.

However, understanding its hormonal effects particularly the suppression of natural androgens and the potential increase in estrogen is crucial for safe and effective use.

RAD140 Suppresses Endogenous Androgens And Increases Estrogen

What is RAD140?

RAD140 is a potent, orally bioavailable nonsteroidal SARM that selectively targets androgen receptors in muscle and bone tissues. Unlike traditional anabolic steroids, RAD140 aims to provide anabolic benefits with reduced stimulation of prostate and other sex tissues. Its mechanism involves selective activation of androgen receptors, promoting muscle growth while minimizing androgenic side effects.

How RAD140 Suppresses Endogenous Androgens

The administration of RAD140 can disrupt the hypothalamic-pituitary-gonadal (HPG) axis, leading to a dose-dependent reduction in luteinizing hormone (LH), follicle-stimulating hormone (FSH), and natural testosterone production. Preclinical studies have shown that testosterone levels can be suppressed to 200−300 ng/dL after 28 days of RAD140 dosing.

This suppression occurs because the body perceives the exogenous activation of androgen receptors as sufficient, signaling a decrease in endogenous testosterone production.(steroids source talk)

RAD140 and Estrogen Levels: Indirect Increase Despite No Aromatization

RAD140 does not aromatize into estrogen directly, unlike anabolic steroids. However, the suppression of natural testosterone can lead to a hormonal imbalance, resulting in a relative increase in estrogenic activity.

This imbalance may cause side effects such as gynecomastia, water retention, and mood swings. Monitoring estrogen-related symptoms during and after RAD140 use is essential to mitigate these risks. (More Plates More Dates)

Tissue-Selective Effects of RAD140

RAD140 exhibits strong anabolic effects on muscle and bone while exerting minimal stimulation on androgen-sensitive tissues like the prostate. Additionally, it has demonstrated neuroprotective effects in brain tissue without activating estrogen pathways.

These tissue-selective properties suggest a reduced risk of androgenic and estrogenic side effects compared to traditional steroids.

Clinical and Preclinical Evidence on Hormonal Impact

Studies confirm that RAD140 suppresses endogenous testosterone and may indirectly increase estrogen levels. While it has shown minimal liver toxicity at effective doses, alterations in lipid profiles have been observed. Implementing post-cycle therapy (PCT) is necessary to restore hormonal balance and mitigate side effects. (Predator Nutrition)

Managing Hormonal Imbalance from RAD140 Use

Regular blood tests are crucial to monitor testosterone, estrogen, LH, and FSH levels during and after RAD140 use. If estrogen-related side effects occur, the use of selective estrogen receptor modulators (SERMs) and aromatase inhibitors (AIs) may be considered under medical supervision.

Recommended PCT protocols can aid in the recovery of natural hormone production and help maintain the gains achieved during the RAD140 cycle.

Potential Side Effects Related to Hormonal Changes

  • Gynecomastia: Due to estrogen imbalance.
  • Low Libido and Fatigue: Resulting from suppressed testosterone.
  • Mood Swings: Associated with hormonal fluctuations.
  • Cardiovascular Risks: Linked to altered lipid profiles.(Annals of Oncology)

Conclusion

RAD140 offers significant anabolic benefits with its selective androgen receptor activation. However, its impact on endogenous hormone levels specifically the suppression of natural testosterone and the potential increase in estrogen necessitates careful monitoring and management. Implementing appropriate PCT protocols and consulting healthcare professionals can help mitigate risks and ensure a safer experience with RAD140.
