RAD 140<\/strong>, also known as\u00a0Testolone<\/strong>\u00a0and more recently, EP0062 (vosilasarm)<\/strong>, is a\u00a0non-steroidal selective androgen receptor modulator (SARM)<\/strong> that has gained significant popularity in the fitness and bodybuilding communities.<\/p>\n\n\n\n

Testolone was developed as a possible treatment for muscle wasting and breast cancer in 2011. Since research shows this SARM has possible neuroprotective properties, there is ongoing research on the role it could play in Alzheimer’s disease.<\/p>\n\n\n\n

Since Testolone is one of the newer SARMs<\/a>, it isn’t as well-researched as LGD-4033 or MK-2866. In fact, the first human trial of RAD-140<\/a> was only recently conducted and finished.<\/p>\n\n\n\n

What is RAD-140?<\/h2>\n\n\n\n

RAD-140 is classified as a SARM because it selectively binds to androgen receptors in muscle and bone tissues. Unlike traditional anabolic steroids, which can affect multiple tissues indiscriminately, RAD-140’s selective action aims to enhance muscle growth and strength<\/strong> while potentially reducing the risk of unwanted side effects<\/strong>. Developed by Radius Health, RAD-140 is currently undergoing clinical trials for various applications, including the treatment of muscle-wasting diseases and breast cancer.<\/p>\n\n\n\n

\n\n\n\n

Research on RAD-140<\/h2>\n\n\n\n

RAD-140 was developed in 2010 and was first described in the literature in 2011. It was originally developed by Radius Health and is now under development by Ellipses Pharma. The first clinical study of vosilasarm, a small (n=22) phase 1 study in women with metastatic breast cancer, was started in 2017 and completed in 2020, with results published in 2019, 2020, and 2022. As of March 2023, vosilasarm is in phase 1\/2 clinical trials for the treatment of breast cancer.<\/p>\n\n\n\n

Preclinical studies have demonstrated RAD-140’s effectiveness in promoting muscle growth and fat loss<\/strong>. In one study, male rats treated with RAD-140 showed significant increases in lean body mass and muscle strength compared to a control group. <\/p>\n\n\n\n

Despite these promising findings, it is essential to note that most of the research on RAD-140 has been conducted in animal models, and human clinical trials are limited. While anecdotal evidence from users reports positive results, such as increased muscle mass and strength, more research is needed to understand RAD-140’s effects in humans fully and to establish its safety and efficacy.<\/p>\n\n\n\n

Mechanism of Action<\/h2>\n\n\n\n

How Does RAD-140 Work?<\/h3>\n\n\n\n

The efficacy of RAD-140 lies in its ability to selectively activate androgen receptors<\/strong>. When RAD-140 binds to these receptors, it initiates a series of cellular responses that promote muscle hypertrophy, fat loss, and overall physical performance. This selective modulation enhances anabolic activity in muscle tissue while preserving the integrity oforgans that might be adversely affected by non-selective steroids.<\/p>\n\n\n\n

Moreover, RAD-140 does not convert into estrogen<\/strong>, which is a common problem with many anabolic agents. By avoiding this conversion, users are less likely to experience side effects such as gynecomastia or water retention, making RAD-140 a more appealing choice for individuals focused on performance enhancement without the unwanted estrogen-related consequences.<\/p>\n\n\n\n

\n\n\n\n

Benefits of RAD-140 (Testolone)<\/h2>\n\n\n\n

The primary benefits associated with RAD-140 include enhanced muscle growth<\/strong>, improved strength<\/strong>, and accelerated fat loss<\/strong>. Users often report significant gains in lean muscle mass during cycles, making it an attractive option for bodybuilders and athletes looking to enhance their performance. RAD-140 appears to promote protein synthesis more efficiently than many other anabolic agents because of its selective action on androgen receptors.<\/p>\n\n\n\n

Increased levels of lean muscle mass<\/h3>\n\n\n\n

As expected from a SARM like Testolone, it can increase lean muscle mass when combined with proper training, nutrition, and rest. Testolone will help your body increase the rate of protein synthesis, which is a process that aids in building and increasing muscle mass. When you push your body during a workout, you actually cause a little damage to the muscles, creating microtears in your muscle fibers. Your body uses proteins to repair those tears, which then builds up your lean muscle mass.<\/p>\n\n\n\n

Increased endurance<\/h3>\n\n\n\n

SARMs like Testolone can help increase your muscular endurance. This is because the anabolic effects of these SARMs boost your body\u2019s metabolism, allowing it to metabolize energy more effectively. As a result, you can spend more time in the gym and should experience shorter recovery time between workouts. This is beneficial because shorter recovery times mean you are less likely to lose muscle mass.<\/p>\n\n\n\n

Promotes fat loss<\/h3>\n\n\n\n

Increasing muscle mass has a beneficial side effect. Muscle weighs more than fat, but did you know that increasing muscle mass can also help decrease fat levels? Muscle maintenance burns more calories than fat. This means that having a higher level of muscle mass can help you burn more calories, leading to fat loss over time.<\/p>\n\n\n\n

Neuroprotective properties<\/h3>\n\n\n\n

One of the most unique benefits of RAD-140 is its potential neuroprotection<\/strong>. It has been shown to activate pathways associated with cell survival in the brain, possibly offering cognitive resilience during cycles. <\/p>\n\n\n\n

Animal studies have found that RAD-140 may help protect neurons from stress or damage, making it of interest in neurodegenerative research<\/a>. Further research into the neuroprotective properties of Testolone is underway. <\/p>\n\n\n\n

\n\n\n\n

Side effects of RAD-140 (Testolone)<\/h2>\n\n\n\n

While RAD-140 is generally considered to be well-tolerated, it is not without potential side effects and risks<\/strong>. As with any performance-enhancing substance, it is essential to be aware of these potential drawbacks before deciding to use the compound.<\/p>\n\n\n\n

Testosterone suppression<\/h3>\n\n\n\n

RAD-140 can suppress natural testosterone production<\/strong>, especially in higher doses or with long-term use. Although it does not convert to estrogen, decreased levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) can still lead to hypogonadism after a cycle.<\/p>\n\n\n\n

It is highly recommended to use proper post-cycle therapy (PCT)<\/a> after running a cycle of SARMs to restore hormone levels and prevent negative effects associated with low testosterone levels. <\/p>\n\n\n\n

Potential liver toxicity<\/h3>\n\n\n\n

While RAD-140 is not a 17\u03b1-alkylated compound like oral steroids, there are a few reports indicating potential increases in liver enzymes<\/strong>, particularly when used alongside other substances known to be toxic to the liver. It’s important to note that hepatotoxicity was not observed in clinical trials, where the administered doses were significantly higher than those typically used by bodybuilders.<\/p>\n\n\n\n

Hair loss and acne<\/h3>\n\n\n\n

As a potent androgen receptor agonist, RAD-140 may exacerbate androgenic side effects such as acne or male-pattern baldness in genetically predisposed individuals, despite its selectivity.<\/p>\n\n\n\n

Mood changes and aggression<\/h3>\n\n\n\n

Some users report feelings of irritability, aggression, or anxiety while using RAD-140. These effects are likely linked to its significant influence on the central nervous system and its activity on androgen receptors in the brain.<\/p>\n\n\n\n

Lipid profile disruption<\/h3>\n\n\n\n

Preliminary studies and anecdotal evidence indicate that RAD-140 may negatively impact HDL cholesterol levels<\/strong> and increase LDL cholesterol, similar to other\u00a0SARMs\u00a0and anabolic agents<\/p>\n\n\n\n

Common side effects<\/h3>\n\n\n\n

In addition to the specific side-effects mentioned, RAD-140 may also cause more general adverse reactions, such as:<\/p>\n\n\n\n
