RAD-140 (Testolone) – Review [2019]

What effects can you expect from RAD-140? Does it really have a similar strength to an anabolic steroid? Is it safe for health, or does it cause cancer?  You will find answers to these and other questions in the following article.

What is RAD-140?

sarm RAD-140 capsulesRAD-140 is, alongside LGD-4033, one of the most popular SARMs used to build muscle mass. 

SARMs (Selective androgen receptor modulators) are considered a safe alternative to steroids. These compounds bind only to androgen receptors present in muscles and bones, producing local anabolic effects without systemic side effects. 

One such substance is RAD-140, which is considered to be the strongest of all SARMs. 

Testolone Benefits

  • Rapid muscle mass gain – RAD-140 is probably the most potent anabolic substance legally available on the market. It can provide 4-6kg of pure muscle mass gain over 6-8 weeks. In terms of strength, it is only inferior to anabolic steroids. 
  • Strength increase – Due to its high anabolic index, Testolone provides enormous strength gains. It is an excellent substance for breaking stagnation and records. It increases the production of red blood cells and thus, the blood supply to the muscle tissue. The most significant increases in strength are observed in the 3rd-4th week of the cycle. 
  • Loss of body fat – RAD-140 is not a substance typically used for cutting, but as a result of high anabolic activity and accelerated metabolism it allows to lose several percents of body fat.
  • Faster regeneration – Another advantage to which high anabolic index contributes. By using RAD, we can train longer and more often.
  • “Pump” – When using Testolone, the muscles retain more water, which makes them look bigger and harder. The veins also become more visible. Effects are similar to those of Anavar in this area. 

Side Effects

Does such a strong anabolic agent have side effects? 

Unfortunately, yes, but luckily they are minor, and once the cycle is over, everything quickly normalizes. The only side effect is, in fact, testosterone suppression, which is noticeable during long RAD-140 cycles (weaker mood and libido from about 8th week). However, unlike steroids, testolone does not affect the HPTA system so typical PCT using SERM drugs is not considered necessary. It is estimated that with RAD-140, testosterone levels will return to precycle levels within two weeks. Taking into account feedback from my gym friends, I believe that it has a reflection in reality. 

However, including PCT drugs like Novalex or Clomid or a good testosterone booster is a good idea in my opinion – especially for cycles >7 weeks, as it helps to preserve more gains. 

If you decide to go for a PCT, you should start it two weeks BEFORE the end of your SARM cycle.

Steroid side effects such as gynecomastia, acne, hair loss, hepatotoxicity, prostate problems, high blood pressure, and cardiovascular issues do NOT apply to SARMs. 

Unfortunately, there are many products on the market that are contaminated with oral anabolic steroids or prohormones. Such products may cause the above-mentioned symptoms. For this reason, SARMs should only be purchased from reliable sources that have a certificate of analysis for each batch. 

Results from using RAD-140

Before and After RAD-140

My personal experience with Testolone

I started my adventure with SARMs about 5-6 years ago, just after the last steroid cycle and I have been using them 3-4x a year ever since. RAD-140 is a part of virtually every stack I use. 

Its results are very similar to those of low doses of testosterone (300-350mg/week) or LGD-4033. The only differences, in my opinion, are the lack of libido increase, which occurs when the previously mentioned substances are used, and much greater strength gains.RAD-140 is a great substance for bulking. It yields phenomenal results in combination with MK-677 and LGD-4033. The usual dose is 20 mg per day. 

During 10 weeks of my first cycle, I gained about 3.5kg (7lb) – keep in mind that I am close to my genetic limit. People who exercise for less than three years can count on even twice as much growth if they have a proper diet and do their best during training. 

Although I’ve been to cycles longer than 8 weeks many times, I can’t comment on how strong the testosterone suppression is as I always threw Novalex in the 6th week – I included it as a preventive measure because I have a dozen or so more packages from the time I used steroids.

Personally, I think SARMs are an excellent alternative for people who for some reason, don’t want or can’t use anabolic steroids. They provide excellent results – certainly much better than any supplements on the market, without any significant side effects. 

RAD-140 Dosage

As I mentioned in the previous paragraph, I believe that 20mg per day is the ideal dosage for beginners. Due to the long half-life, it can be taken once a day. 

Usually Testolone cycles last 6-10 weeks. I would advise people using RAD-140 for the first time not to cross the 8-week limit.

Stacking with other SARMs

We can combine RAD-140 with other SARMs to enhance the results. 

RAD-14010mgweek 1-8
MK-67730mgweek 1-8
S2310mgweek 1-8

This is my favorite SARM stack. It gives fantastic gains in muscle mass and strength, while at the same time regenerating joints. Each of these substances works very synergistically with each other. In my opinion, this is the best stack for bulking, regardless of the experience at the gym or the number of SARM cycles. Each of these substances affects other receptors, causing a simultaneous increase in mass, strength, pump, and regeneration. During the use of this cycle you can gain up to 10 kg. 

LGD-403310mgweek 1-6
RAD-14010mgweek 1-6

This combination is rather recommended for beginners. Although these are two sarms with the highest anabolic index, they work in a very similar way, so the effect is not as spectacular as one might expect. Of course, both substances have their unique benefits; therefore, the effect of their combination will be greater than from using a single substance in a double dose.

Where to buy RAD-140?

Unfortunately, most of the SARMs present on the American market have hardly anything in common with their names. Most of the recently tested products had only a negligible amount of the declared substance. Moreover, it is a common practice among manufacturers to add prohormones and steroids. For this reason, you should buy SARMs only from reliable suppliers – they should preferably have a Certificate of Analysis (CoA) issued by an external laboratory for each batch sold. 

Stores we recommend:

Proven Peptidesproven peptides logo

Currently the most popular SARM store in the world. Over the years of their presence on the market, they have earned a reputation as one of the most trusted sellers of SARMs. Apart from single comments about broken bottles during transport, it is difficult to find any negative opinions about this vendor.

The store offers SARMs only in the form of solutions. Each bottle comes with a pipette and information about the concentration of the agent. There is a contact phone on the website, so you can get all your questions answered in just a few minutes.

Proven Peptides offers a loyalty program called “Peptide Points” in which the collected points reduce the cost of future orders. Shipping from the USA.

Chemyochemyo logo

Relatively young shop. It is quickly gaining popularity, especially among Reddit users. This is probably due to very attractive prices and high transparency of the shop – certificates of analysis of each product are placed directly on the website.

Just like Proven Peptides, they offer SARMs only in the form of a solution. Unfortunately, there is no pipette attached to the bottles. However, it is possible to buy a 1ml syringe for $1 on their website. Shipping from the USA.

Swisschemsswisschems logo

The youngest store on the list. It is not very popular at the moment. It is dictated by the relatively high price of the products in comparison with the competition. In contrast to its predecessors, it offers SARMs in the form of capsules and injections. Apart from SARMs, the store also offers PCTs, aromatase inhibitors, nootropics, peptides and drugs for erection problems. Shipping from the USA.

Unfortunately, despite the fact that it was our favourite shop for over 3 years, we are forced to change our recommendation. In recent months, the quality of products has significantly decreased and contact with the store itself has become more difficult. We also received a lot of negative opinions about the time of shipment and the purity of products.

Frequently Asked Questions

At what time should I take Testolone?

SARM should preferably be used in the morning at least 10-15 minutes before breakfast – this ensures optimal absorption. 

How to use RAD-140 in the form of a solution?

The label should state how much product is dissolved in ml of solution. In case of water solutions, sprinkle an appropriate amount of agent onto the juice/tea/water. In case of oily solutions, sprinkle it onto a piece of bread or directly into the mouth. 

For how long is RAD-140 detected in the body?

Testolone remains detectable for approximately 30 days after discontinuation. 

How long till effects kick in?

First effects can be seen in the first week. However, the biggest increases in strength and mass are observed from the 3rd week of the cycle. 

What results can I expect with first RAD-140 cycle? 

The effects of the cycle depend not only on the substance itself but also on our commitment to training and diet. Under optimal conditions, we can expect 3-5kg of lean mass over a 6-8 week cycle. 

Does RAD-140 cause acne?

In most cases not. However, it is worth mentioning that SARMs can affect the production of growth hormone and testosterone, causing problems associated with an abnormal balance of hormones. Personally, despite the huge inclination to acne, I have never observed SARMs influence its intensity in any way. 

Does RAD-140 cause hair loss?

The mechanism of action and the research carried out do not give any reason to believe that tesolone can cause baldness. Some individuals say it does, but most of them have used SARMs from unverified sources. I also know from the autopsy that by focusing too much on a side effect, we often have the impression that we are affected. I myself have often been paranoid when using steroids, but I still have NW1. 

Which SARM is better than RAD-140 or LGD-4033?

Both SARMs are very similar to each other. RAD-140 is slightly stronger. Nevertheless, if I were to use them alone, I would choose LGD-4033.

Is RAD-140 legal?

Testolone is legal in most countries of the world, including the United States. However, it is placed on the WADA list, so it cannot be used by professionals.

Does RAD-140 require PCT?

PCT is not required for this substance, but I still recommend using it. It allows us to keep more gained muscles.
