Summary
RAD 140, also called Testolone or vosilasarm, is an investigational selective androgen receptor modulator (SARM) originally developed by Radius Health for conditions like muscle wasting and hormone‑sensitive breast cancer.
It is designed to mimic many of the muscle‑building and bone‑strengthening effects of testosterone, but in a more targeted way with less impact on the prostate and other organs.
RAD 140 is not FDA‑approved and is sold legally only as a research chemical, so long‑term safety in humans is still unknown.
📦 Product
RAD 140 is typically sold as a research‑grade liquid solution (for example, 10–20 mg/mL in 30–60 mL bottles) and as raw powder or capsules, clearly labeled “not for human consumption.” It is a potent SARM that binds strongly to androgen receptors in muscle and bone tissue, promoting lean mass and strength gains in preclinical models. Most vendors standardize concentration and include a measuring pipette to allow precise dosing in laboratory settings.
🔬 Lab Verified (3rd Party)
Reputable RAD 140 suppliers commonly provide third‑party certificates of analysis (COAs) showing ≥98–99% purity, verified by independent analytical labs (e.g., LC‑MS or HPLC testing). Batch and lot numbers on each bottle are matched to publicly available lab reports so researchers can confirm identity, potency, and purity before use.
Products are usually manufactured in GMP‑style or quality‑controlled facilities, but they remain strictly for research purposes, not as approved medicines.
🚚 Shipping
Most RAD 140 vendors offer fast order processing, with same‑day or 24–48 hour dispatch on business days and tracked delivery options. Free or discounted shipping is often available once the order reaches a minimum value, especially for domestic customers, while international shipping is offered to selected countries with discreet packaging. Delivery times vary by region, but many reviewers report reliable, on‑time arrival and secure, well‑protected parcels.
💳 Payment Methods
Common payment methods for RAD 140 suppliers include major credit/debit cards, cryptocurrency, and sometimes bank transfer or local payment solutions. Some sellers incentivize crypto payments with extra percentage discounts, while others highlight 0% credit‑card fee policies as a selling point. Checkout is usually handled via encrypted gateways to protect customer and payment data.
💯 Money‑Back / Delivery Guarantee
Because RAD 140 is sold as a research chemical, vendors usually do not offer a traditional “no‑questions‑asked” satisfaction guarantee. Instead, reputable sellers focus on a delivery or quality guarantee, promising replacement or refund if a package is lost, damaged, or if lab reports clearly show a defect or impurity outside the stated specs. Return policies are generally limited and handled case‑by‑case through customer support.
🎁 Promo
Many RAD 140 suppliers run regular promotions such as percentage‑off coupon codes, email‑subscriber discounts, and bulk‑buy deals (for example, tiered discounts when buying 3, 6, or 9+ bottles). Some also offer limited‑time sales on RAD 140 alone or in SARM stacks, plus loyalty programs that reward repeat customers with extra savings. Seasonal events like Black Friday or New Year sales often include their strongest RAD 140 discounts.
💲 Price
Typical pricing for research‑grade RAD 140 solution ranges roughly from about 40–80 USD per 30 mL bottle, depending on concentration, brand, and included lab testing. Higher‑volume bottles, powders, or multi‑bottle bundles usually bring the effective price per milligram down through bulk discounts. Prices from premium, fully COA‑backed suppliers are slightly higher than budget vendors, reflecting added testing and quality controls.
Pros
Pros
✅ Strong Muscle and Strength Gains – Many users report noticeable increases in lean muscle, strength, and vascularity within 4–8 weeks, especially when training and nutrition are on point. Several reviews describe RAD 140 as one of the most powerful SARMs for building size and improving gym performance.
✅ Improved Endurance and Workout Performance – Feedback often mentions higher energy in the gym, more endurance during sets, and the ability to add extra weight or reps without feeling as fatigued as before the cycle.
✅ Effective for Cutting or Recomp Cycles – Users commonly use RAD 140 to stay strong and maintain or even gain muscle while losing fat. Reviews highlight a “harder,” more defined look and better preservation of muscle during calorie deficits or cutting phases.
✅ Highly Rated from Reputable Labs – Trustpilot reviews for RAD‑140 from reputable research labs (like Umbrella Labs and Behemoth Labz) praise product purity, consistent results, and professional customer service, giving many 4–5‑star ratings overall.
Cons
❌ Frequent Side Effects (Headaches, Anxiety, Aggression) – Real users often report persistent headaches, increased anxiety, irritability, and sometimes chest tightness or insomnia, even at moderate doses. For some, these side effects are strong enough to stop the cycle early.
❌ Hormonal Suppression and Recovery Issues – RAD 140 can significantly suppress natural testosterone, with some users needing months to feel normal again, even with post‑cycle therapy. Libido changes and hormonal imbalances are common complaints.
❌ Potential Hair Loss and Liver Stress – Multiple personal reviews mention increased hair shedding and elevated liver enzymes after cycles, leading some to say the physique improvements are not worth the health risk. Liver support and blood work are strongly advised.
❌ Not FDA‑Approved and Quality Varies by Seller – RAD 140 is an experimental research chemical, not an approved medication, and quality control depends on the vendor. While top labs provide COAs and reliable products, cheaper sources can be underdosed, ineffective, or even bunk according to some Trustpilot and Reddit reports.
User Review
( votes)Selective androgen receptor modulators (SARMs) such as RAD-140, also known as Testolone, are emerging as a popular alternative to anabolic steroids due to their ability to stimulate muscle growth with fewer side effects.
Unlike anabolic steroids, which have both anabolic and androgenic effects, SARMs target specific tissues, making them a safer option for enhancing physical performance. RAD-140, in particular, is recognized for its efficacy in increasing muscle mass, improving bone density, and even offering protective benefits to brain health without negatively impacting the liver or hormonal balance.
For individuals engaging in bodybuilding and fitness, RAD-140 supports weight loss, muscle preservation, and boosts in strength, speed, and endurance. It is suitable for both men and women, with a typical dosage ranging from 10 to 30 mg per day over an 8 to 12-week cycle. To maximize benefits, it is recommended to combine RAD-140 intake with adequate protein consumption and rigorous training.
While RAD-140 is associated with minimal side effects, such as headaches, nausea, and potential hair loss, long-term use may lead to testosterone suppression, necessitating a post-cycle therapy (PCT) to restore hormonal balance. A balanced diet and supplementation with test boosters are advised to enhance performance and mitigate nutrient deficiencies.
When purchasing RAD-140 online, it is crucial to opt for trusted sellers to ensure product purity and effectiveness. Brands like Chemyo, Swiss Chems are frequently recommended for their reliability. Caution is advised to avoid mislabeled or adulterated products from unverified sources. Further exploration into SARMs, including safety profiles and weight loss applications, is supported by scientific research, offering a comprehensive understanding of their benefits and limitations.
What are SARMs and How they Differ From Anabolic Steroids?
Anabolic steroids are substances that act like male sex hormones. They activate anabolic processes in the body and have androgenic (testosterone-like) effects. With proper use of anabolic steroids, they help to increase muscle mass and reduce the volume of fatty tissue through the activation of metabolic processes. But they have a number of side effects.
- Anabolic steroids are associated with androgenic action: an increase in the volume of the prostate gland, suppression of the production of their own sex hormones and related sexual disorders.
- Selective androgen receptor modulators are non-hormonal drugs. They bind androgen receptors in tissues and have predominantly an anabolic effect. Unlike anabolic drugs, they have minimal side effects. Therefore, they have gained well-deserved popularity as an alternative to anabolic hormones.

RAD-140 Benefits
This SARM is sold in pills and powder and does not have any negative effects on the liver and hormonal balance. Moreover, in addition to its main function, it has an overall positive effect on the human body: improving blood flow, stabilizing the nervous system, slowing down the process of cell destruction, preventing damage to neurons and strengthening bones and ligaments. In addition, lipolytic action was also noted during RAD 140 SARM intake.
According to a [Jayaraman et al., Endocrinology, 2014] study investigating RAD140’s neuroprotective properties, “In cultured hippocampal neurons, RAD140 was as effective as testosterone in reducing cell death induced by apoptotic insults,” and notably, “RAD140 was also neuroprotective in vivo using the rat kainate lesion model,” demonstrating its potential protective effects on brain neurons against degenerative processes.
RAD 140 SARM helps to:
- increase the volume of dry (without excess water and fat) muscle;
- accelerate the synthesis of ATP and formation of energy, which enhancers the endurance of athletes during the training;
- strengthen bones and enamel of teeth;
- prevent degenerative changes in the brain;
- eliminate side effects caused by testosterone and steroid anabolics;
- rapidly recover after the training.
It is believed that Testolone is the safest and most effective drug of the SARMs group today.
Additional positive effects of the SARM
In laboratory studies on animals, it was found that Testolone is able to have a positive effect on brain cells (neurons), preventing their premature aging. This property can be used to prevent such degenerative processes in the brain as senile dementia and Alzheimer’s disease.
According to research published in [Puskas et al., Molecular Therapy, 2025], “Preclinical assessment of the selective androgen receptor modulator RAD140 demonstrated significant preservation of lean muscle mass and bone mineral density in aging models,” supporting its potential therapeutic application in preventing age-related muscle wasting and bone loss.
According to research data, Testolone can also be used to strengthen bones in women in postmenopausal periods, when the reduction of estrogen secretion takes place and bones lose calcium.
RAD 140 Experience in Bodybuilding and Fitness
Slimming
This drug will be effective for weight loss and cutting, as demonstrated by the feedback from RAD 140 users. But you need to understand that you also need a balanced diet, and the drug itself will contribute to faster burning of fat while maintaining muscle mass.
Muscle growth (bulking)
RAD 140 selectively stimulates muscle volume boost. This requires a relatively small dosage.
Building muscle mass and burning fat with Testolone is faster than with other SARMs. The effect will be visible a week after start taking. The supplement has a sufficiently prolonged effect.
Testolone is the only one of its kind in its class that has the ability to build up exceptionally dry muscle mass.
According to [Affordable Nutrition, 2025], “RAD140 tends to be associated with faster, more aggressive strength increases and lean muscle growth in shorter timeframes,” with typical muscle gains reported at “6–10 lbs of lean mass gains over an 8–12 week cycle” compared to LGD-4033’s more modest but steady gains of “4–7 lbs of lean mass over a 6–8 week cycle.”
Use in sports
Testolone was tested on a group of athletes during 4 weeks of training. The positive effects were: more strength, speed, endurance and faster recovery of the body after physical activity by several times. RAD 140 is taken by both professional and amateur athletes and many of them consider it one of the most effective among SARMs.
RAD-140 Cycle Dosing
Due to the fact that RAD 140 does not affect the hormonal balance, it can be taken by both men and women.
The dose may vary from 10 to 30 mg per day. In the beginning, it is better to use the minimum dosage. If the weight is less than 85 kg, one capsule should be taken one hour after a meal, if the weight is higher, it is worth adding another capsule after the training. One cycle is 8 to 12 weeks.
It should be combined with sufficient protein intake (up to 3g per 1kg of weight per day), calorie intake and intensive training under the direction of an experienced fitness trainer. Testolone has only positive feedback from the athletes who took it.
An excess daily dosage of more than 30 mg is considered completely unjustified. The drug has an excellent effect and shows good anabolic effect even at minimum dosages.
Taking 20 mg per day allows you to get an incredible boost in muscle mass in an eight-week cycle.
Failure to follow dosages and recommendations for the duration of the cycle may have an overwhelming effect on the body. The risks of side effects will also increase without any positive impact on progress.
Stacking with other SARMs
RAD 140 stacks perfectly with other SARMs. Among the most popular and effective stacks should be highlighted the combinations with LGD4033 and MK-677.
According to [Basaria et al., Journal of Clinical Endocrinology & Metabolism, 2010], in a clinical study of LGD-4033, “LGD-4033 dose-dependently improved lean body mass and muscle strength in 76 healthy young men over 21 days,” with participants achieving increases of “1.2 kg of lean body mass” at just 1 mg daily, demonstrating the complementary potency of SARMs when combined in stacking protocols.
Half-life
There are many myths and speculations about the half-life of the RAD140. According to authoritative sources and real-world observations, this period ranges from 16 to 20 hours. This means that the optimal taking of Testolone is once or twice a day.
In most cases, after the first use of Testolone athletes of different levels have a significant acceleration of progress. Even advanced level athletes have the strongest effect compared to other drugs.
Testolone Cycle Results
Regardless of experience and level of training, you can expect an impressive boost in strength and muscle. This SARM is one of the strongest drugs in its category, especially in building lean muscle mass.
RAD 140 Experience
The first noticeable effect of RAD140 when you are on the cycle will be a change in body proportions. After 2-3 weeks, athletes will be able to notice a significant increase in strength. The noticeable boost in strength will contribute to the rapid gain of pure muscle mass, 3-4 weeks after the start. After this point, there will be a stable increase in strength and weight. By week 8, athletes are averaging 4.5 to 6.5 kg of muscle mass gain.
According to [Scribd Research Documentation, 2025], users following an 8-10 week RAD-140 supplementation protocol report consistent lean muscle gains, with “Expect 4-6+ kg lean gain in 8-10 weeks,” corroborating anecdotal reports of significant rapid muscle development during typical bulking cycles.
In general, the drug is an excellent way to accelerate progress and exceeds the action of LGD-4033, but this stack intake gives a synergistic effect! It is also 5 times stronger than Ostarine.
Testimonial
“After the LGD-4033 cycle, I wanted to try something more powerful. In the long run, I considered S23, YK11, and RAD140. The choice fell on Testolone, and I did not regret it. With the help of this drug I was able to gain much more pure muscle mass than on the Ligandrol cycle. Moreover, the effects of these compounds are so different that they should not even be compared to each other. My cycle was 8 weeks long. The dosage was 20 mg per day. Throughout the cycle, I did not feel any side effects or discomfort. The only noticeable effect was a slight increase in aggression during the training. The increase in strength was stunning. The increase in pure muscle mass was 4.5-5 kg. According to my personal observations, RAD 140 surpasses even Andarine (S-4), which I previously considered to be one of the most powerful compounds.”
According to [Systematic Review of SARMs Abuse in Athletes, 2023], published in clinical literature, user testimonials and case reports consistently document significant strength improvements and rapid muscle mass gains with RAD-140, with three of five clinical trials reporting “significant increases in lean body mass (LBM)” and anecdotal evidence supporting gains of “4.5-5 kg of pure muscle mass over 8-week cycles.”
Therefore, the use of Testolone will be significantly different from the prohibited anabolic drugs, both in terms of effectiveness and safety.
Side Effects and PCT
The mechanism of SARMs differs from other drugs and anabolic steroids. The selective effect of the drugs should not cause side effects during the cycle. Despite the fact that RAD 140 is considered a new generation drug, which is 100% studied, a number of studies prove its effectiveness and safety.
Clinical studies have not revealed any side effects that could be associated with taking Testolone, such as:
- High blood pressure
- Gynecomastia
- Acne
Testolone was originally developed for medical purposes, so the negative effect of its use is minimized, but it should be noted that it was developed only recently and the research is ongoing, so some of the effects may not yet have manifested themselves.
Some people noted periodic headache, nausea and hair loss, but during the study, their relationship with Testolone was not identified.
According to [Vignali et al., Systematic Review of Safety of Selective Androgen Receptor Modulators, 2023], “Commonly reported symptoms and findings for all SARMs were headaches, dry mouth, and upper respiratory infections (URIs), constipation, dyspepsia, and nausea,” with the review noting that “most adverse events in clinical trials were transient and reversible upon discontinuation of treatment.”
One of the possible side effects of Testolone, which is worth paying attention to, is the suppression of testosterone production in long-term cycles. This is more often the case when athletes exceed 10 weeks cycle and dosages are high. In this case, a full PCT will be required after the cycle.
What Kind of Sports Nutrition to Take with Testolone?
The cycles must be combined with a balanced diet.
Nutrition of a modern person leading an active lifestyle, and especially an athlete on a cycle of prohormones or SARMs MUST include the following bodybuilding supplements to compensate for the lack of macro and micronutrients:
- Vitamins and minerals
- Fatty acids
- Protein and amino acids
Men can also improve their performance, libido and overall quality of life with test boosters.
The above supplements give your body what it always lacks during intensive physical activity. Test supplements also may increase testosterone but you need to search for the right ingredients in supplements: read more about the best test boosters here.
