RAD 140 Suppression

RAD 140 Suppression is a side effect of using RAD 140 Testolone and it refers to the suppression of endogenous testosterone production in your body. What it means is that RAD 140 Testolone can take a toll on your body’s natural testosterone production requiring you to go on a RAD 140 PCT so that your body gets back to producing testosterone normally as it did before you started with the RAD 140 cycle.

Obviously, there’s much more to how RAD 140 suppression feels. Read on to find out more about it…

What Is RAD 140 Suppression?

RAD 140 or Testolone happens to be one of the strongest SARMs used by bodybuilders these days. Even though RAD 140 results can be quite good and it is preferred by a lot of guys to bulk up as well as to cut down fat, it is not entirely safe. There could be many side effects and one of the most worrying of these is testosterone suppression.

RAD 140 Suppression

A lot of gymgoers use RAD 140 stacks to speed up muscle growth and enhance strength, but I should mention here that this is a SARM that you should not be playing with. In other words, before you begin your RAD 140 Cycle, you should be aware of the side effects, benefits, pros, and cons so that you can avoid the pitfalls and make desirable gains at the same time. The only other SARM that can be more suppressive than RAD 140 is YK 11. You can check the comparison between YK 11 and RAD 140 here.

Why Does RAD 140 Suppression Occur?

If this is what you are wondering, let me explain a little bit…

When you take RAD 140, it increases the amount of testosterone in your body. However, this testosterone is not what is naturally produced, rather exogenous testosterone.

In other words, soon your body catches up with the fact that it has more than enough testosterone supplied through an exogenous source. It reacts by decreasing the secretion of the LH hormone in your body, which tends to slow down your natural testosterone production.

By the time, you are done with an 8-week RAD 140 cycle, your baseline testosterone level will be lower.

When Does RAD 140 Suppression Occur?

I must mention it clearly that when talking about the side effects of RAD 140 or any other SARM, there’s very little clinical evidence available and whatever information is available is per reviews from actual users.

Anecdotal evidence suggests that most users start feeling the suppressive effects of RAD 140 six to seven weeks into the cycle and that too when the dosage is within the normal and healthy range.

In other words, testosterone suppression is likely to occur sooner if you consume it in bigger dosages. For instance, if you consume 20-30 mg per day, there is a great possibility that you will experience test suppression sooner than 6 or 7 weeks into the cycle.

As a matter of fact, if you consume a heavy daily dose such as 20-30 mg per day, then you might experience RAD 140 suppression as early as 2 weeks into the cycle!

This is why it is recommended that you should not have more than 10 mg of RAD 140 Testosterone/ day.

How Does RAD 140 Testolone Suppression Feel Like?

Some of the common effects of RAD 140 Suppression could include the following:

  • Drop in libido or sexual appetite
  • Brain fog
  • Extreme Lethargy or lack of energy

RAD 140 Testolone Suppression

One of the most common effects of testosterone suppression is that it can result in extreme lethargy and as a result of it, you lose all your motivation or desire to do anything. This could easily put you in a fix since you also lose the will to hit the gym and workout. It goes without saying that lethargy can make you feel extremely tired and everything starts appearing like a chore and is enough to pull your mood down.

But this is not all!

Yet another effect of extreme lethargy is that it can translate into mood swings and constant fatigue.

Just imagine what it would feel like lying in your bed or couch for the whole day and being highly irritable too. It can make your life as well as that of people around you miserable.

One of the initial effects of testosterone suppression is a drop in your libido or sex drive. You won’t feel like having sex at all. Now, this could also seriously hamper your relationship.

Another problem that could arise as a result of testosterone suppression is that it can lead to erectile dysfunction which of course, can put you under a lot of stress.

Having said that, I must bring to your notice that different people experience different symptoms and you must watch out for them. One of the best ways is to keep a daily journal recording your mood levels, energy levels, and of course, changes in your sex drive if any.

PCT Protocol for a RAD 140 Cycle

The best thing about PCT for SARMs is that it happens to be far simpler as compared to what it is for anabolic steroids. This is yet another difference between SARMs and steroids.

If you follow the protocol correctly, you are not going to experience any side effects. One of the best parts about this is that after the PCT, you tend to retain most of the muscle gains that you made during the SARM cycle.

One thing that you need to keep in mind is that you should do your PCT with a good quality supplement. Some people speak highly of over-the-counter PCT drugs while others do not hesitate to call them trash. Ultimately, your results depend upon the quality and effectiveness of the PCT drug that you use.

One of the best ways to lay your hands on a good drug is to opt for companies that made their products with lab-tested ingredients. Moreover, you should also check online user reviews before you opt for a particular PCT drug.

Tips To Avoid a PCT Cycle

Here are some simple tips to avoid PCT after your RAd 140 Cycle:

Avoid Cycling RAD 140 for More Than 8 Weeks

There are 2 main reasons why you shouldn’t extend your RAD 140 Testolone Cycle beyond 8 weeks:

  • Even though RAD 140 is one of the best SARMs for bulking, you won’t be able to see much muscle gain beyond 8 weeks. Thus, it becomes pointless to continue after this period.
  • Secondly, with each passing day beyond that 8th week, your chances of experiencing a stronger testosterone suppression increase manifold.

Thus, you tend to lose on both these counts.

RAD 140 Suppression

Avoid Heavy Dosages

The severity of suppression heavily depends upon the dosage.

If you are a first-timer, it is best to limit your daily intake to just 5 mg of RAD 140 a day and closely monitor how your body reacts to it. If everything goes well for a couple of weeks, you may increase the daily dose to 10 mg. However, under no circumstances should you increase the daily dosage beyond 10 mg.

Keep A Tab On Your Blood Work

One of the best ways to monitor the level of suppression is by constantly getting your blood tested. You should have your blood examination done before and during the cycle. It can clearly indicate if you are going through suppression and that whether you should continue with the cycle or forego it immediately.

Try A Natural and Legal Alternative

This is what I would highly recommend if you want to be safe and experience all the benefits of a SARM.

Brutal Force is a brand that is gaining widespread recognition for its legal and safe range of supplements that not only mimic steroids but also a wide range of SARMs.

RADBULK from Brutal ForceRADBULK from Brutal Force mimics all the benefits of RAD 140 without any of its negative side effects. It is made with 100% natural ingredients and is simply great for bulking, enhancing strength, as well as burning fat in your body. Another benefit is that you don’t need a PCT after you are done with a RADBULK cycle.

The best part is that you can stack it with other legal SARMs from Brutal Force for better and faster results. Two of the most popular stacks from Brutal Force include:

  • Ironbound Bulking Stack – This stack, as the name suggests, helps you gain iron-hard and solid muscle quickly. It combines RADBULK with OSTABULK (Ostarine alternative), LIGABULK (LGD 4033 alternative), and YKBULK (YK-11 alternative). This stack is amazingly powerful and can help you bulk up like a boss in just an 8-week cycle.
  • Select Stack – This stack is perfect for gaining lean and rock-hard muscle mass. It combines RADBULK with OSTABULK (Ostarine alternative), and ANDALEAN (Andarine alternative). While Ostbulk helps you gain muscle, Andalean is highly effective for burning excess fat so that you are left with high-quality and ultra-lean muscle mass.



Does RAD 140 cause suppression?

Yes, of course, it does. As a matter of fact, Testolone RAD 140 is a highly suppressive SARM and some guys may experience suppression even with low dosage. It is not recommended to beyond 10 mg a day when on a RAD 140 cycle. If however, you are a newbie you should start with an even lower dosage such as 5 or 2.5 mg per day. Better still, you may try legal and 100% safe supplements that can help you get results as close to actual SARM without any side effects or PCT. 

This is what RADBULK from Brutal Force is all about. Check the above article for more.

What does RAD 140 do to your body?

RAD 140 has many benefits and some of these include fast muscle growth and increased bone density. It is also likely to boost your strength. Not just this, it is also supposed to be an excellent fat cutter. 

How long does RAD 140 stay in your system?

It is known that RAD 140 may be detected in your body till at least 8 days after you have consumed a single 10 mg dose.


It is clear that RAD 140 is suppressive in nature and that you need a PCT after you are done with a single cycle of this SARM. However, it is better to opt for natural and safe alternatives that can help you get excellent results without any side effects or testosterone suppression.
