What is Rad140 Testolone?

Known as both Testolone AND Rad140, this selective androgen receptor modulator is considered one of the most powerful mass building SARMS around. Alongside being able to selectively bind with the androgen receptors in your bones and muscles, Rad140 can also safely encourage growth and development in both – without interfering with any of your other biological functions i.e. hormone production.

In fact, Testolone is different to a lot of SARMs, because instead of focusing purely on mass gains, it has traded mass for strength. And this trade is probably one of the wisest choices you could ever make because these go hand-in-hand.

Think about it… If you lift hard enough – and eat right – then the mass will naturally follow.

Thanks to its anabolic effects, it’s reported that you can experience results even with a low dose. However, Rad140 is actually illegal and shouldn’t be used for human consumption. If you were to buy it online, there’s no guarantee you’ll get the same dose every time. If you want to try it, we recommend you use our safe and legal alternative: Testol 140

What else is Rad140 used for?

Testolone may be better known for its bodybuilding capabilities; however, thanks to the Phase I clinical trials being performed by Radius Healthcare, its reputation extends into other areas too.

Currently, research is being done to determine Rad140’s impact in the treatment of weight loss caused by Cachexia, and whether it can be used as a safer alternative to Testosterone replacement therapy. This is due to it being only a partial agonist/antagonists to androgenic regulations in the prostrate – meaning it can help reduce prostate enlargement (which is common amongst anabolic steroid users).

Similarly, thanks to it only binding to the androgen receptors in your bone and muscle tissues; Testolone can safely trigger lean muscle mass growth; prevent muscle wastage, and at a high enough dosage, can help you to lose fat.

NOTE: One thing to remember with this particular SARM though is that it is only available as a research chemical. Bought for anything else, it’s illegal.

How does Testolone work?


Like most SARMs, Rad140 has an affinity for certain androgen receptors in your body – in this case, the ones in your bone and muscle tissues. When it encounters these particular receptors, Testolone binds with them before mimicking the action of testosterone and DHT (androgens which are basically hormonal compounds).

For example, it will trigger an increase in nitrogen retention as well as boosting protein synthesis, enabling you to gain lean muscle mass faster.

However, unlike synthetic androgens, Testolone doesn’t aromatize (convert testosterone into estrogen – leading to saggy man boobs); it doesn’t get converted into DHT; it doesn’t bind to the androgen receptors found in your prostate, and it doesn’t cause liver toxicity.

Rad140 benefits

The great thing about Testolone is that you can use it for both bulking and cutting, which is quite handy when you’re bodybuilding as you can save on the cost of switching between products.

Instead, thanks to its ability to suppress androgenic side effects, you can confidently incorporate it into your cycle without fear of later developing man-tits or experiencing problems with your prostate.

But that is not the only benefit you have got to look forward to…

Even if you use it on its own, Testolone can also offer the following Rad140 results:

      1. Increased strength – as we mentioned at the beginning, Rad140 is renowned for boosting your strength. As quickly as 2 weeks into your cycle, you will begin to notice a difference in your lifts, as they’ll become easier to do. Similarly, you’ll be able to last longer and workout more intensely during sets.

      2. These strength gains are very real and will come on gradually and consistently – not something even anabolic steroids can guarantee. Quite often they will give you a false sense of strength that can lead to injury. Rad140 doesn’t have such problems.

      3. Lean, hard muscle gains – true your muscle gains with Rad140 won’t be as pronounced as some other SARMs; however, similar to Anavar and Masterone, it can produce decent hardening effects, as well as helping you to experience great pumps.
        Because of this, Testolone is a great finishing compound and is particularly useful if you’re using a steroid known to cause water retention, as it will work to counteract this problem.

      4. Improved sense of well-being – Rad140 can help you to escape feelings of lethargy which are fairly common at the end of steroid cycles (or if you’re in poor shape). Instead, Rad140 can give you a much-needed boost, helping to make your workouts more enjoyable and productive, whilst lifting your mood.

      5. Minimize androgenic side effects – we’ve said it once and we’ll say it again, as a non-hormonal compound, Rad140 won’t get converted into DHT or estrogen. Nor will it cause aromatization. And this is good news for your body, as the last thing you want after hitting the gym hard is to develop man boobs and lose hair. Instead, Rad140 can help to reduce swelling in your prostate gland.

      6. Increased fat loss – we won’t lie and say Testolone is the best at encouraging fat loss. However, by boosting protein synthesis and prompting your body to use existing fat stores for energy, you will naturally see a boost in your metabolism as well as increased fat loss.

        Similarly, as you build up more muscle mass and workout more aggressively; your body will need to access its fat reserves in order to support this increased energy demand. And who can say no to fat disappearing from in and around your gut? Not us that’s for sure.

      7. Protect your brain – one of the original therapeutic purposes behind Rad140 was to act as a preventative measure against Alzheimer’s. By protecting your brain from amyloid beta proteins – and increasing brain cell growth – it was believed that it could reduce the onset of this condition.

NOTE: this is all in theory and as of yet actually hasn’t been approved by the FDA.

What Testolone side effects can you expect?

Man suffers testolone side effects

Given that this compound has an anabolic to androgenic ratio of 90:1, there is no escaping the risk of side effects.

During a typical 8-10 week Rad140 cycle, there is a possibility that you’ll experience any of the following:

  • Increased aggression – some of the aggression you experience whilst pumping weights and boosting your strength, may start to feed into your general behavior. Don’t fret – you won’t go into a full roid rage. However, you might become more reactive, angry and aggressive. This usually starts to diminish once you come off your Rad140 cycle.
  • Testosterone suppression – we don’t think there is a SARM around that doesn’t cause a little suppression to natural testosterone production. The problem with RAD140 though is that it can suppress natural testosterone production by up to 70%, meaning you will need to do PCT to help restore this loss. NOTE: this usually occurs when you have taken a high Rad140 dose for an extended period of time. The key is to be careful with your Rad140 cycle, so you don’t unnecessarily trigger a shutdown in testosterone production.
  • Increased blood pressure – now this one has caused a bit of debate, as clinical trials claim this shouldn’t happen. However, some users (not all) have reported suffering from raised blood pressure levels.
  • Nausea – from an upset stomach to feeling like you’re going to vomit, this side effect is not that common. It usually only occurs when you’ve taken too high a dosage.
  • Hair loss/hair shedding – if this does happen it is relatively mild. NOTE: there is no evidence linking this to Testolone (meaning it could be the result of whatever else users have stacked it with).

    Another thing you need to remember is that Testolone is still relatively new and we’re still learning more about it – including its side effects. Sure, the clinical studies that have been done so far haven’t seen anything bar the ones we’ve listed above.

    Although it’s not known to cause the dreaded “man boobs”, acne, or gyno (aromatization) the only way to get these results without the side effects is to use a natural alternative. There’s no “safe” dose of the real thing, but you can use Testol 140 instead which is completely safe.

    Dosages and Rad140 Cycles

    Not only does Testolone have a half-life of 15-20 hours – meaning you only need one Rad140 dose per day – milligram per milligram, Rad140 is stronger than most SARMs. Knowing this, it makes sense that you won’t need a lot to start experiencing positive Rad140 results, as it already packs a powerful punch.

    But that is the thing…

    Users can’t seem to agree on what is the best dose.

    For instance, most will tell you that it is better to start off with just 10mg a day (for the first couple of weeks). This is more than enough to get you started because even at low dosage it is anabolic. From here, researchers suggest moving up to 20mg for the remainder of your cycle.

    And this Rad140 cycle is pretty typical of a lot of users. Spread over 6-8 weeks, you will get decent results.

    But this is not the only Rad140 cycle you can try…

    Other users suggest taking 15-20mg a day for men and 10mg a day for women, for up to 10 weeks; whilst others recommend taking as much as 30mg a day.

    You would also need to finish your cycle with a PCT in order to get your natural testosterone back to normal - although it doesn’t always work perfectly. If you use Testol 140, our legal alternative, instead, you don’t need to cycle and don’t need to use a PCT. We’ll help you raise your testosterone production naturally, instead of suppressing it, replacing it with the fake stuff and then trying to get your naturally low production back to where it was.

    What about stacking?

    You would think that people would be content with using Rad140 on its own, given how powerful it is. However, some users like to stack Rad140 with other SARMS such as LGD-4033, due to Testolone’s focus being more towards strength than muscle gains. With LGD-4033’s help, you can experience better bulking results.

    TIP: NEVER do a Rad140 cycle for longer than 10 weeks and NEVER take more than 30mg a day, as this excessive use could cause natural testosterone production to shut down.

    Rad140 Results – What to Expect

    Truthfully, it is hard to compare Testolone to other SARMs given that it is more effective than LGD-4033 and MK-2866.

    Whilst it may be better known for its strength boosting capabilities, this SARM can encourage lean muscle mass gains, as well as some fat loss (even whilst you’re building muscle).

    Cutting – users have reported fat losses of 9lbs, whilst still managing to achieve muscle gains of 7lbs (when at a 400-500 calorie deficit).

    Bulking – users have gained as much as 10.5lbs of lean muscle mass during a clean bulk (which they managed to retain once the cycle was over).

    Other things you’ll notice:

      • 2-3 weeks into your cycle, you’ll notice a rapid boost in strength.
      • After 3-4 weeks you will see visible muscle gains.
      • After only 8 weeks you can expect to pack on as much as 10-15lbs of muscle.
      • Rad140 is considered to be 5 times stronger than Ostarine.

      Weighing the pros and cons – Should you buy this SARM?

      We could talk for days about Testolone and whether it is worth introducing into your workout regime, but we appreciate that you haven’t got time for that.

      Below we have stripped away the glitz and glam so you can see the real pros and cons of this SARM.


        • Rad140 is stronger and more potent than most SARMs, meaning you can expect to see results fast.
        • 1 bulking cycle can produce 10-15lbs of muscle mass in 8 weeks.
        • By weeks 2-3 of your cycle, your strength will have increased.
        • By weeks 3-4 of your cycle, you will see visible gains in muscle.
        • Due to its anabolic nature, it can produce results with as little as 10mg a day.
        • Doesn’t cause aromatization, gyno or hair loss.


          • Needs to be combined with PCT to minimize testosterone suppression.
          • Too high of a dose for too long of a cycle e.g. over 30mg a day for longer than 10 weeks, can potentially shut down natural testosterone production.
          • Rad140 can suppress testosterone production by up to 70%.
          • It is renowned for increasing aggression (outside of the gym) in users.
          • It is better at boosting strength than packing on muscle.
          • It is not entirely free of side effects: it can cause nausea, testosterone suppression, acne, and aggression.
          • Can only be bought for clinical research – all other purchases are illegal.
          • More clinical trials/research is needed as it is still relatively new – we still don’t fully understand its long term effects as there are NO human studies (yep, that’s right. None!)

          The verdict? It’s time to go NATURAL

          Natural weightlifter

          On the surface, Testolone looks like the perfect alternative to anabolic steroids…

          Sure, it is not entirely free of side effects (increased aggression, acne and nausea). And true, there is an incredibly high risk of testosterone suppression (70% to be exact) or even complete testosterone shutdown if you take it for too long and at too high a dosage (more than 30mg). However, some might say that these side effects are minimal compared to others.

          Yet here is the thing…

          Despite all of these benefits – and they’re pretty impressive ones – 10lb+ lean muscle mass gains, 9lbs fat loss and massive boosts in strength (in as little as 2-3 weeks); you can achieve these EXACT same results 100% naturally, safely and legally.
