What is YK11?
YK11 is actually a myostatin inhibitor. This sort of compound is able to break down our genetic muscle-building wall and allow us to gain more muscle mass than normal.
We all want to look fantastic in our swimwear and have all eyes on us. However, sometimes, it’s just not possible to do it with diet and exercise. Sometimes, we need extra help — some sort of muscle enhancer!
Now, we know that most people would immediately think of steroids now. But given the fact that these come with a bunch of side effects no one needs, we ought to find an alternative.
Luckily, that’s exactly when YK11 comes into play. This compound is bound to make our gym dreams come true in less time than we think. So without further ado, let’s learn more about it!
Although the market is full of various muscle enhancers, it seems that there’s nothing quite like SARMs. Indeed, selective androgen receptor modulators have the power to change our bodies without us having to go bald, lose our libido and suffer through acne.
Although one of the most potent substances on the market, YK11, was a late bloomer. In fact, its effects were discovered in 2011 by Yuichiro Kanno. He conducted the initial study on YK11 in which he stated that it was a type of an androgen modulator.
The main side effect, according to Mr. Kanno, was that YK11 lead to aggression. Still, in smaller doses, this was negligible.
Yet YK11 is not really a SARM per se. People have classified it as one because it does attach itself to androgen receptors, just like SARMs do. However, unlike those modulators, YK11 doesn’t lead to the release of androgenic and anabolic agents.
Does this mean that it’s less powerful than other SARMs? Absolutely not. In fact, we could say that it’s currently one of the strongest compounds on the muscle enhancement market. Why? It’s because it leads to the release of a compound called follistatin.
- Increases bone strength
- Increases muscle strength
- Burns fat
- Increases recovery
- Increases stamina
- No negative side effects
If it’s not a SARM, then what is it?
Now, to really understand how YK11 works, we have to explain it from scratch. First of all, we need to understand that every person out there, man or woman, has a genetic muscle-building wall. This wall is what inhibits us from gaining muscle mass constantly.
Indeed, if we were to gain muscle muss all the time, then we wouldn’t be able to walk at all. Humans are just not made to carry an excessive amount of muscle on their bodies. In the end, no matter how much we work out or diet, at some point, we’ll reach our limit. It’s sort of like hair growth — after a while, it just stops because we don’t have the genetic makeup for luscious locks like Rapunzel.
How does YK11 work?
Now, if you remember, we mentioned a compound called follistatin. This is the thing that stops myostatin from destroying our muscle-gaining plans. In essence, when we take YK11, myostatin goes back to its day job and lets us do our thing at the gym, thus, allowing us to gain more muscle mass (the lean kind).
YK11 works similarly to DHT (dihydrotestosterone), which is a potent cousin of testosterone and another follistatin inhibitor. However, unlike that substance, YK11 doesn’t lead to the deterioration of our overall health.
Is YK11 useful in medicine?
Of course, whenever we hear of compounds that seem a bit too good to be true, we’re immediately suspicious. After all, steroid use has burned us more times than we would like to admit.
Still, when it comes to YK11, we can note both benefits and side effects. In any case, we first need to talk about how it can be used in medicine.
The way follistatin works is quite interesting. When released, it can affect proteins and hormones. Most commonly, it affects:
- FSH (follicle-stimulating hormone).
Why does this matter, you may ask? Well, it matters because when it interacts with activins, for example, it can affect our reproductive health and cancer cells. Meanwhile, its interaction with myostatin is solely related to our muscle growth.
A word or two about cancer
So this seems worrying, right? Whenever we see the word “cancer,” our first thought is to run as fast as we can. But hold on! There’s more to this story.
It all depends on the type of cancer we’re talking about. Studies have shown that follistatin can actually inhibit or promote different types of cancer. In fact, during rat studies, it showed promising results in regard to breast cancer. It worked as a type of protection; although it didn’t reduce the tumor growth, it definitely did stop the cancerous cells from spreading.
But those are just rats. Luckily, human studies have also been conducted, and they showed that high follistatin levels could actually help humans survive breast cancer.
So in the end, there are a few types of cancer we can (sort of) treat with follistatin:
- Liver cancer — in rats, it boosted the growth and recovery of the liver after a tumor was removed. However, there was something strange here. Those tumors also had high follistatin levels, so it’s not entirely clear whether or not this compound would help.
- Ovarian cancer
- Non-small cell lung cancer
- Breast cancer
Strangely enough, the compound that gets released when we take YK11 can also have a negative effect on the growth and spreading of cancerous cells of the following types of cancer:
- Stomach cancer
- Skin cancer
- Esophagus cancer
- Prostate cancer
Let’s get back to the main subject of our article — YK11. Given that some people classify it as a SARM, we can expect similar benefits from it, like the ones from Andarine or Cardarine.
However, what’s important to note here is that YK11 is a lot more versatile than most of us would think. In fact, we can use it for both cutting and bulking up.
Since it binds to the androgen receptors and puts myostatin back into its original role, gaining a lot of muscle while on YK11 is easy. During the 8-week cycle, we can expect to gain about 5 to 8 pounds of it, which isn’t bad at all. In fact, when compared to steroids and their side effects, gaining so much in so little time with almost no consequences is really like a dream come true.
Still, we should never expect to gain more than that. After all, our bodies need to adjust to our muscles. No one likes stretch marks, especially not on their arms and legs.
What’s fantastic about YK11 is that it can also help us burn a ton of calories. Since it leads to more muscle mass, that logically leads to more calories burned each day during workouts. Moreover, those same reasons are why it inhibits fat storage. In essence, when on YK11, one can become a fat-destroying machine in no time at all!
Another great benefit of using YK11 is that it can act as a protective agent for the muscle mass we already have. Most of you already know that working out each day does lead to some form of muscle wastage. In fact, if we decide to exercise strenuously every day and cut calories at the same time, our muscles could suffer.
But that’s why YK11 is fantastic! While taking it, we won’t experience those consequences, as it effectively promotes lean tissue growth and preserves our muscle mass at the same time.
Can everyone use YK11?
Although this myostatin inhibitor is a suitable replacement for steroids, that doesn’t mean everyone should use them. In general, before we start taking any supplements, we ought to talk to our doctor and determine the dosage.
Those with pre-existing medical conditions should refrain from using YK11. However, what’s interesting is that this compound can actually help those who were born with some genetic defects.
Generally, these people have a hard time gaining muscle mass, as they usually don’t have the freedom or the ability to do all those exercises bodybuilders love. Nevertheless, with YK11, they can grow their muscle mass faster than they would by sticking to a regular diet and a limited exercise plan.
Even though there are many benefits to taking supplements, we cannot help but research if there are any side effects to them as well. Luckily, SARMs don’t usually come with any major consequences, and neither does YK11 as a myostatin inhibitor.
Most people say that taking YK11 led to excessive hair growth all over their body. Now, this isn’t that surprising at all, but can we even classify it as a side effect? Some people would absolutely love for this to happen!
Nevertheless, let’s say that’s a consequence no one wants to hear about. Another side effect can be baldness — the entire opposite of the above-mentioned. Using YK11 can make someone already starting to go bald lose hair more rapidly than usual.
Libido and sexual health
We’ve already mentioned that follistatin can affect the prostate, i.e., lead to prostate cancer. That also means that it can reduce our sex drive and make us almost frigid. However, that’s what steroids do as well, and in case you were wondering, YK11 leads to only a minor decrease in our sex drive in comparison to steroids. It just doesn’t lead to the same androgenic issues the latter is known for.
High blood pressure and liver toxicity
Although this headline could scare you, we just wanted to mention that using YK11 could lead to a slight increase in your blood pressure. Moreover, it causes low-level liver toxicity, which is a common side effect among SARMs. However, it’s nowhere near as the level of toxicity steroids generate.
Suppression of testosterone
Since most people say that YK11 is a SARM, it also has one distinct side effect most SARMs have: testosterone suppression. However, with the right post-cycle support supplement and by using only the right doses during the cycle, our bodies can bounce back pretty quickly from this side effect.
Stacking YK11 with SARMs
Even though YK11 is quite potent by itself, there are some ways for us to boost its effects even more. Namely, most users opt for the YK11 and Testolone combination.
Do note, though, that proper dosages are key here, as we don’t want to harm ourselves. It’s best to start small and ask a doctor or a bodybuilding expert with which dosages we should start. Generally, 5 mg of both during the first week is a good idea, but that goes for men only. Women would have to adjust the dosage to their needs, as they may react differently to it.
Dosage and length of use
Whether we decide to stack YK11 with other SARMs or use it on its own, it is of the essence to use it for no more than eight weeks. If we go over this limit, we could seriously endanger our health and even become extremely aggressive.
This aggression is also connected to the dosage we’re using. Depending on the sex, we’ll take different doses. For men, the optimal dose is 2–5 mg twice a day.
YK11 has a short half-life (about 6 to 8 hours), so taking it twice a day should generate the gains we’re after. However, women ought to be cautious with it and use smaller doses. They should take 0.5–2.0 mg per day and never go above those numbers. Otherwise, they could go through virilization, otherwise known as the development of masculine physical traits and hair growth.
Most of the side effects connected to YK11 are minimal. Still, we ought to do our best to avoid them by taking the right doses and never going over the limit. If done right, the side effects won’t bother us at all, as there’s little chance they’ll even come up.
The wait is over — YK11 to the rescue!
So is YK11 a good choice if we want to stay as far away from steroids as possible? We say that it definitely is. The science behind it, although still obscure, shows promising results. Moreover, it’s the most potent compound, aside from steroids, that could actually give us that hard muscle look and incredible gains.
In the end, it depends on what we’re looking for and what we want to achieve at the gym. However, taking YK11 in small dosages and only for eight weeks shouldn’t become a major issue in our lives. After all, if we’re doubtful, we can always start small and take even less than the recommended amount. We’ll see if there are any mindblowing results in just a few weeks and if we’re reacting well to it.
