YK-11 Reviews – YK11 SARMs Dosage, Side Effects & More…

What is YK11 SARM?

YK11 is a selective androgen receptor modulator with a hybrid steroid status. It is a synthetic anabolic steroid that works by stimulating muscle protein synthesis.

Furthermore, YK11 was first studied in Japan.

The researcher behind it is Yuchiro Kanno.

According to the benefits analysis of this drug, YK11 can increase muscle mass via pathways other SARMs cannot modulate, activates follistatin (a myostatin inhibitor), and does not provide androgenic effects on the scalp and prostate.

YK11 Indications

Based on animal trials, YK11 targets the androgen receptors in the muscles and bones. Because of this, it can be used for the following indications:

  • Muscle wasting or muscle sarcopenia
  • Diabetes
  • Healthy weight management
  • Osteoporosis and bone-related health issues

This drug is also associated with myostatin.

The latter is a negative regulator of muscle mass and YK11 acts as a myostatin inhibitor.

According to one scientific data from Korea, when there is myostatin inhibition, there could be a decreased rate of mortality due to sepsis caused by myostatin.

Can Everyone Use YK11 for Muscle Growth?

Although YK11 comes with many health benefits, not everyone can experience these.

There are some contraindications when it comes to YK11, and in this section, we will discuss some of them.

1) Pregnant and lactating women

There have been no human clinical trials for YK11 and this means that it is not yet safe to be used by pregnant and lactating women.

Currently, YK11 is under pregnancy category X. Meaning, this drug has teratogenic effects that can harm the fetus.

If you are pregnant and wish to take YK11, it is highly advised to seek medical consultation beforehand to avoid extremely dangerous events for you and your child.

2) Patients below 18 years old

YK11 is not approved by the FDA and buying it may be done for research purposes only.

Thus, patients below 18 years old should avoid this medication, especially when they are purchasing it for personal use.

3) Patients with liver problems

The chemical structure of YK11 is very similar to anabolic steroids.

Since most anabolic steroids cause liver damage, it is also possible for YK11 to produce this damaging adverse effect.

Thus, those patients with previous and pre-existing liver problems should avoid this drug to prevent further health complications.

4) Those with erectile dysfunction

Other SARMs affect testosterone levels positively while others affect it negatively.

When it comes to YK11, keep in mind that this drug can suppress natural testosterone production.

As we all know, when there are low T-levels or hypogonadism, it could cause a decline in sexual function due to erectile dysfunction and libido. 

Based on some reports, this drug only causes mild testosterone suppression, but patients with ED should still avoid it to prevent the worsening of the condition.

The Cons of YK11

Aside from the contraindications, YK11 also comes with some disadvantages.

Most of these are focused on the side effects, and in this section, we will discuss each of these.

1) Testosterone suppression

Although YK11 can increase fitness and muscle strength, one of the things you should consider before using it is that this drug can cause testosterone suppression. 

When your testosterone levels are low, you can experience some changes such as low sex drive, depression, reduced mental focus, and fatigue.

2) Potentially toxic to the liver

In one extensive research from Ohio, it was reported that YK11 is well tolerated and causes no liver damage.

However, some users of it experienced liver malfunctioning after getting a lab test.

This means that YK11 is not yet proven to be safe not just for the liver but for the kidneys as well. Take note that other SARMs can also cause liver damage. 

Since there have been no human studies for YK11, using these drugs for building muscle tissue is not yet recommended.

3) YK11 dosage is difficult to determine

The YK11 dosage is usually divided into two. If you take it orally, 2 capsules should be the maximum.

When you take more of YK11, it can already cause potential harm to your health. 

Most SARMs require post-cycle therapy and many users of YK11 also consider post-cycle therapy for 4 weeks after the 8 weeks of treatment.

According to them, this cycle support is necessary to reduce the liver toxicity effects of YK11.

4) Other side effects

The anabolic activity of YK11 also comes with other side effects.

These include acne, increased aggression, hair loss, and joint pain.

It is contradicting, though, because YK11 is used to target underlying bone issues. But when taken in higher doses, it could cause joint pain.

It is also worth mentioning here that the body reacts differently to different SARMs.

So, before you purchase a drug that targets androgen receptors, you should go for the one that can suit your health needs.

What People Say About this Lean Muscle Mass Enhancer

YK11 is popular among bodybuilders, weight lifters, and gym enthusiasts because it not only promotes healthy muscle growth but it also reduces fat mass.

Moreover, most of these users took YK11 for 8 weeks and they used a PCT afterward.

The most common PCT drug was Clomid, and its dose is 50 mg per day for 2-6 weeks. 

Some users also reported that this drug is safe to be stacked with other SARMs that target androgen receptors like Cardarine for better muscle gain results.

Also, YK11 can promote fat loss which could improve your body weight.

For potential users of YK11, it is worth mentioning that this partial agonist of the androgen receptor comes with several very interesting advantages both for physical and mental health.

What We Like About YK11: The Pros of YK 11 SARM

YK11 is a partial agonist of the steroid receptor and mimics the effect of a full steroid hormone SARM.

It targets those receptors that are specifically in muscle and bone tissues, avoiding alternative areas such as the prostate, and prejudices aspect effects that may turn up with elevated androgenic hormone.

In this section, we will discuss the benefits and advantages of using YK11.

1) Enhance muscle and bone tissue health

YK11 targets muscle growth and many users have seen significant progress from using this drug.

One great thing about it is that it only causes minor androgenic hormone drop compared to other SARMs.

Not only these but YK-11 can also increase muscle size by producing new healthy muscle cells.

Aside from enhancing muscle health, YK11 is also used to support bone health, including proper ligament development.

According to scientific research from Taiwan, YK11 can be used to improve bone strength and bone fracture repair.

This means that YK11 is an effective substance for those who are suffering from osteoarthritis, osteoporosis, tendonitis, and other bone-related health issues.

However, if you are taking other drugs for these conditions, seek medical consultation before taking YK11 to avoid drug interactions.

Usually, SARMs can interact with NSAIDs, the drugs being used to manage pain due to bone and muscle pains.

2) Fat reduction

YK11 is an effective drug for weight loss as it can effectively burn fat.

Many users of YK11 take it not just to enhance their physique but to also manage their body weight.

To understand better, keep in mind that YK-11 works by stimulating your body’s natural thermogenesis.

This is a state where your body burns fat and this fat is used as your source of energy.

In one clinical data from the United Kingdom, it was reported that YK11 can promote weight loss because it can torch the fat in the adipose tissues.

The total fat mass of the subjects in this study fell from 41.8 to 32.0. 

Along with this, their blood pressure also increased.

For this reason, YK-11 has the potential to improve the cardiovascular health of people.

Some reports also say that YK11 can reduce the quantity of salt-storing ability inside your body to prevent water retention.

3) Improve insulin sensitivity

It is also worth mentioning that YK-11 is beneficial for obese patients and those with diabetes as it can improve insulin sensitivity.

In one clinical data published in the Journal of Medicine & Science in Sports & Exercise, it was reported that YK-11 can increase glucose tolerance and can prevent insulin resistance in response to a high-fat diet.

What to Watch Out for When Buying YK-11

If you are an athlete, bodybuilder, or gym enthusiast, you have to know if YK-11 is suitable for your health.
