In this blog post, I am going to compare Ostarine MK 2866 vs Testolone RAD 140. We’re going to compare these two SARMs “side by side” and you’ll find more valuable information about how they can help in terms of strength, muscle gains, fat loss as well as side effects.
I decided to write this article in comparison to these two SARMs taking into consideration that these are two of the most popular SARMs out there. Let’s get started.
What is Ostarine – MK-2866
Ostarine popular as MK 2866 is a Selective Androgen Receptor Modulator (SARM) that is very popular for being among the mildest and also the most researched SARM out there. This means that it’s a SARM with lower chances of causing side effects. Moreover, it has the most scientific data backing it than any other SARM you can find.
This SARM is researched for treating muscle wasting disorders and it’s currently in phase II of clinical trials. It means that it’s the SARM with the highest probability of getting FDA approval in the next few years.
As with any other SARM, it works by selectively aiming at the androgen receptors. It would cause less side effects but is still capable of increasing muscle mass, enhancing strength and stamina, improving body appearance and vascularity, helping to lose weight, and others.
What is Testolone – RAD 140?
RAD-140 is popular as Testolone is another popular Selective Androgen Receptor Modulator (SARM) with a similar mechanism of action to other SARMs. It targets androgen receptors selectively.
RAD 140 is one of the strongest SARMs you can buy. It’s a product that can produce significant results in terms of muscle gain, fat loss, and especially strength enhancement. Because of these, it’s common for people running the Testolone cycle to break their Personal Records (PRs) in the gym.
But except from making individuals stronger, it also makes them look much better. That’s why many people love RAD-140. It makes people have a “dry look” without causing water retention (like LGD 4033 Ligandrol can). It helps you experience great pumps, looking bigger and leaner while becoming stronger.
Ostarine vs Testolone Benefits
Of course, one of the first things that people would love to know – the benefits that you could experience from using MK 2866 in comparison to RAD 140. We’re going through various different benefits separately.
But I have to mention that overall, RAD140 (Testolone) is going to offer more impressive benefits than MK2866 (Ostarine) and that’s because it’s a stronger SARM. However, this doesn’t mean that RAD 140 is an overall better choice though.
Except for the benefits, you should take into consideration the side effects that you can expect too. Plus, you should compare each benefit individually.
Only after going over each benefit and side effect that you can experience from both of these SARMs, should you decide which is a better option for your goals. You could also check SARMs before and after the results article for a better understanding of what you can expect in terms of benefits. Until then, let’s compare the three main benefits that everyone searches for: muscle mass growth, strength increase, and fat loss.
When talking about the muscle building potential, RAD140 is an obvious winner over MK2866. That’s because you’re way more likely to gain way more muscle mass on RAD 140 than you would on MK2866.
According to reports, you’re able to gain almost twice as much. For example, people gain about 2-6 lbs of lean muscle on Ostarine, but they are gaining around 4-12 lbs of lean muscle on Testolone.
Nonetheless, it’s important to understand that it mostly comes down to your diet and workout plan. A person who is strict about a good diet and workout plan is likely to gain more on Ostarine than a person on Testolone without a good workout and nutrition plan.
We’re just talking about their potential of gaining muscle.
Therefore, while Ostarine (MK2866) is an awesome SARM that is surely going to help you improve strength considerably, it cannot compare to the strength increase potential of Testolone (RAD140).
Of course, it comes down to your response, dosage, numbers pre-cycle, diet, workout, and so on and so forth. Moreover, it’s important to know that strength is likely to go down a bit after the Testolone or Ostarine cycle. However, you’re still able to maintain most of your strength gains after the cycle with proper nutrition and workout. Point is – you’re still getting stronger after the cycle than you used to be before the cycle.
RAD 140 and MK 2866 are both helpful compounds when it comes to fat loss. They are compounds that people often use to build muscle or for body recomposition (losing fat while gaining muscle at the same time).
Both these compounds seem to be equally effective when talking about losing fat. RAD 140 is better at growing muscle mass on top of losing body fat and that’s why it’s a superior SARM in terms of benefits overall.
Nonetheless, according to some people, Ostarine is still a better choice for fat loss. While they seem to be equally effective at burning fat, some people suggest it’s still offering some better results. We can’t be sure whether Ostarine is better than Testolone in terms of fat loss, but if it is, then there’s not a huge difference if any at all.
However, remember that you need to remain in caloric deficiency to lose fat. But people suggest that a slight caloric surplus of only 100 or 200 kcal a day over their maintenance, combined with a great workout and Ostarine or Testolone still helps them lose fat at the same time while they gain lean muscle tissues.
MK2866 vs RAD140 Side Effects
As we can notice, RAD 140 seems to be a clear winner over MK2866 when talking about benefits.
So, some people may think that Testolone is overall better. But that’s not actually the case because you also need to take a look at the side effects too.
For example, if we would care only about the benefits, then there’s just nothing better than anabolic steroids. However, we all know that steroids are far from being the best. And that’s because of the potential side effects they come with.
So, let’s check and compare the side effects of Ostarine MK2866 and Testolone RAD140.
Both Ostarine as well as Testolone are capable of causing natural testosterone suppression. While none of them will suppress testosterone as much as steroids would (and won’t cause complete shutdown), Ostarine is still not going to suppress testosterone as much as Testolone would.
In fact, a lot of people suggest that they can avoid the use of Post Cycle Therapy (PCT) after an MK2866 cycle. While I still recommend having a form of PCT plan after each SARM cycle, it proves how mild this side effect is.
RAD140, however, is capable of causing major suppression, and especially if there are involved some higher doses. That’s why it’s wiser to start with RAD140 in lower doses and see how it would affect you during the cycle as well as after the cycle when you recover the natural production of testosterone.
For more information about PCT for SARMs I suggest you read this post.
Although aggression is a rare side effect among SARMs, it’s still a side effect that people may experience during their RAD140 cycle. On the other hand, Ostarine is not going to increase aggression.
Increased aggression is helpful in the gym, but it can be detrimental outside the gym. I personally never had aggression issues while on the RAD140 cycle (and of course, never on the MK2866 cycle). But some people report they do have aggression issues while on Testolone.
It’s worth noting that all SARMs are hepatotoxic (damaging the liver) to a certain extent. While they are far not as damaging as anabolic steroids, it’s still a good idea to protect your liver during the SARMs cycle. Also, it’s worth noting that some SARMs are more hepatotoxic than others.
Cycle length and dosages are also very important. For example, a long cycle is exposing your liver to way more damage than a shorter one. Moreover, a low dosage of Ostarine is much less hepatotoxic than a very high dosage.
Yet, when talking about dosages within the recommended guidelines, RAD 140 is slightly more hepatotoxic than MK2866. However, both of them are still safe in normal dosage for a normal period during the cycle. There’s nothing to worry about as long as you use them correctly and you do not have some pre existing health issues before starting the cycle.
While joint pain is a side effect that’s not very commonly reported by a lot of people, it’s still something you can experience. I personally experience it with higher dosages. That’s why I always have joint support supplements and try to keep doses lower.
I personally notice that Ostarine is capable of causing more joint pain than Testolone, despite it being a milder SARM.
When talking about SARMs – they are fairly safe in terms of hair (unlike anabolic steroids). However, it’s important to know that they are not all safe. A lot of people who run SARMs cycles would love to keep their hair and avoid hair loss. I’m one of them, for example.
According to reports and researchers, Ostarine MK2866 is causing almost no hair. It’s not common for people to experience hair shedding on Ostarine. Usually, only those who are genetically predisposed to it and when involving higher doses. Moreover, most suggest that the hair comes back after the cycle.
However, on the other hand, we have Testolone RAD140 which is much harsher on your hair. While it’s still affecting most people who are predisposed to experiencing this issue, it’s way more common to experience hair loss on Testolone than on Ostarine. And the hair loss would be worse too.
Ostarine MK 2866 vs Testolone RAD 140 Prices
There is not a major difference when talking about the prices between Ostarine vs Testolone. However, there are still some. Testolone RAD140 is usually a bit more expensive than Ostarine MK2866. Usually, about 10-20% more expensive.
Remember that the prices are determined by each brand in particular. You can check below some examples of the Ostarine vs Testolone prices. But these are the prices that the manufacturers are dictating.
Moreover, the prices might change with time. It all depends on the manufacturer.
In whatever the case, be ready to spend a few dollars for a good quality MK2866 or RAD140. That’s because, unfortunately, a lot of companies out there are selling bunk or under dosed products. They can either be ineffective or even dangerous.
In the end, I have to mention that RAD 140 and MK 2866 are similar and popular SARMs. Nonetheless, Testolone is surely a stronger compound than Ostarine, that’s why it has some more and nastier side effects too.
Testolone is a better option for people who are having more experience with SARMs.
Ostarine, however, is a better option for those who are searching for a beginner SARM cycle.
Moreover, many people stack these two SARMs together for even better and more results. But I only recommend doing so if you previously had experience with each of these SARMs separately. That’s because if you develop side effects, you wouldn’t know which one caused them if you started with both together.
In the end, it’s highly important for you to learn about how to use each of these SARMs in order to experience the best benefits and the least side effects.
