If you’ve ever heard of RAD-140, it’s because it’s one of the most popular and powerful bulking SARMs on the market. The fact that you landed this article means that you’re considering taking it and just want to know more.
In this article, I’ll be providing a science based rad 140 review, so you can decide whether it’s for you. This review covers how to take it, proper dosage, and even a post cycle therapy to be extra safe. Let’s go.
What Is RAD 140?
RAD-140, also known as testolone, is probably the best SARM on the market period. It’s got the best anabolic to androgenic ratio of any SARM, at 90:1.
This means that they have 90% of the muscle building effects of steroids, but have 1% of the side effects. That’s pretty much no side effects if you think about it.
To put this ratio into context- one of the most common supplements for getting jacked is testosterone. Testosterone has an 100:100 anabolic to androgenic ratio. 100% benefits but tons of side effects that harm you in the long run. With that being said, if you know someone who’s on testosterone for lifting, tell them they can get close to the same amount of benefits for almost no side effects.
Steroids are more hormonal when compared to SARMs. This means that it alters your hormone levels, and could permanently mess with them. SARMs aren’t hormonal because of their mechanism of action. SARMs like RAD-140 only bind to androgen receptors in skeletal muscle, while common steroids like tren, winstrol or anavar bind to all your androgen receptors. This leads to organ problems.
How Does RAD 140 Work?

Rad 140 works the same as all other SARMs, by binding to androgen receptors in skeletal muscle. This action pretty much tells your body to build more muscle, and it does extremely well. It also avoids organs so you minimize harmful side effects.
This SARM typically starts kicking in within a week, and most people report noticing them within 24-48 hours. RAD 140 will help you start packing on muscle extremely fast. Users also report more endurance and faster recovery times when using RAD 140.
Testolone Benefits

- Build muscle
- Shred fat
- Gain strength
- More energy
- Improve endurance
- Faster recovery time
- Safe
RAD 140 gives you a ton of benefits, so much it may be hard to talk about all of them. We’ll start off with the anecdotal bro science first. Gym rats across the globe claim that RAD 140 can help you put on 30 lbs of muscle in 8 weeks, along with shredding fat. These effects are similar to taking a medium dose of real steroids like tren or winstrol.
But remember, the real magic lies in that there’s hardly any side effects (which we’ll talk about later). Aside from building muscle, RAD 140 has been shown to help shred fat as well. Some people who used RAD 140 to help them with a body recomposition report losing 15 lbs of fat! The great thing is, you can lose fat without muscle wasting because we all know if you want to lose weight, you’ll lose some muscle in the process.
Another benefit of RAD 140 is that you gain a ton of strength. It’s been reported that people doubled their pr’s within just one cycle! So- depending on the type of training you do you could hypothetically double your strength while on RAD 140.
One other thing that people say when they take RAD 140 is that they have improved energy levels. This isn’t surprising considering that the whole point of anabolic steroids is to help you do more and stimulate growth.
I know most gym bros don’t care about endurance, however if you’re an athlete you should seriously take this point into consideration. RAD 140 improves your endurance drastically. Obviously it’s not a good idea to take it if you’re getting tested and will get caught by the ADA, but if you’re trying to improve your endurance and build muscle at the same time, I would seriously consider using RAD 140.
A faster recovery time is another benefit you get when using RAD 140. As I mentioned before, the whole point of steroids is to help you do more and stimulate growth in your body. You can lift longer, harder and more intense when using testolone.
The last benefit which we’ll cover in the next section is that testolone (RAD 140) is safe. But, one size never fits all so consult a doctor or professional before using it.
RAD 140 SARM Safety
Studies point to SARMs being safe for human consumption.
One study by Boston University School of Medicine shows an increase in physical performance along with minimal size effects..
“The last decade has witnessed unprecedented discovery effort to develop selective androgen receptor modulators that improve physical function and bone health without adversely affecting the prostate and cardiovascular outcomes. SARMs hold promise as a new class of function promoting anabolic therapies for a number of clinical indications, including functional limitations associated with aging and chronic disease, frailty, cancer cachexia, and osteoporosis.

USC SARMs Study
This study shows that taking the SARM RAD-140 is actually safer than testosterone replacement therapy, or (TRT).
The increased risk for prostate cancer makes T therapy a risky treatment option (71). Moreover, even in neurons, high doses of T can be harmful rather than beneficial (72, 73). In this regard, SARMs like RAD140 can be better alternatives to T because they are only partial agonists or antagonists to androgenic regulation of prostate while still having androgenic effects on other tissues such as muscle and brain. In addition, higher doses of SARMs as compared with T might still promote neuron viability and not induce apoptosis, making them a suitable therapeutic strategy against age-related disorders such as AD.

Think about all the 50+ year old dudes (or sometimes younger) on TRT due to low testosterone levels… none of them are dying or getting sick from side effects. In fact, men on TRT enjoy doing it for the most part. If SARMs are safer than TRT, you shouldn’t have much reason to worry.
Most people who claim SARMs are bad (which they can be if bought from scammers who don’t sell the real stuff) point to the fact that they’re not FDA approved. But, if testosterone replacement therapy is approved by the FDA and SARMs have been proven to be safer, there’s no reason to be concerned about FDA approval.
The only reason SARMs haven’t been FDA approved yet is because they’re new chemicals, AND, big supplement companies don’t want other supplements better than their own on the market. Big pharma is ruthless and doesn’t hesitate to knock down other businesses that pose a threat to them.
RAD 140 Legality:

When most people hear about SARMS and their amazing affects they think to themselves “are these actually legal?” Luckily, they are legal in most countries.
They’re in a legal gray area due to their liquid form.
Technically speaking, SARMS are legal for research purposes. They are not intended for human consumption, however everyone finds ways around that.
SARMs are currently legal in the following countries:
- United States
- Europe
- Canada
- Australia
- United Kingdom
In most other nations, such as India, the Netherlands, Sweden, Pakistan, and others, purchasing and possessing SARMs is lawful.
The only times you would want to avoid them are if you’re being tested and would get in trouble if you were found to be taking them. For example: an olympic athlete, a military member, or a college/high school athlete. I would also avoid them if you’re under 18 because your body is still developing and we don’t know how they impact growing bodies.

How To Take RAD 140

When you order SARMs from rats army (my recommended source) they’ll come in a dropper bottle. The drop part has markings for dosage which we will cover later. It’s very easy to take RAD 140, you simply squeeze out your desired dose and put it on your tongue.
I don’t recommend mixing it with water because even the flavored SARMs don’t taste good, plus it’s hard to mix. Just take your shot and rinse it down with your desired drink.
You don’t have to wait for certain mealtimes, just take it at the same time every day. For example, if you took it at 6pm right after the gym, you would do that for the rest of your cycle.
RAD 140 Dosage
It’s really up to you for how much you want to take. I wouldn’t go over 30 mg a day because you don’t want to OD on SARMs. SARMs are shown to be safe in up to 30 mg a day.
Typically, you can get good results with small amounts of Rad 140, even 5-10 mg a day. For beginners I would start with 10 mg a day for your first cycle, and if you want to do another after, work your way up to 20-30 range.
Testolone Cycle
In order to be safe when taking SARMs, you need to do something called a “cycle.” A cycle is where you take it for a couple weeks and then do a post cycle therapy.
- Dosage: 15mg/day of RAD140
- Length: 6-8 Weeks
- Training: Workout Of The Gods
- Diet: Clean Bulk At 500-1000 Caloric Surplus
- Post Cycle Therapy: Testosterone Boosting Supplement
Time | Protocol |
---|---|
Weeks 1-8 | Use SARMs Daily |
Weeks 9-12 | SARMs Post Cycle Therapy (Take Testosterone Boosters) |
Weeks 13-16 | No hormone shifting supplements (be natty) |
Where To Buy RAD 140
