Is YK11 the most powerful SARM in the market today? Everyone seems to believe so and for good reasons. The chemical delivers insane muscle building results within extremely short periods that most of the other selective androgen receptor modulators cannot match. In fact, some reports are actually claiming that YK11 might be a synthetic steroid and not a SARM. Are these reports true? Well, on the one hand, we can see YK11 delivering unbelievable results that can only be compared to steroids. On the other, the chemical is not as dangerous as anabolic androgenic steroids. This explains why even though the chemical structure and working mechanism of the substance are not 100% similar to SARMs it is still categorized as one.
The truth of the matter is that YK11 is a Myostatin inhibitor. This chemical reduces the activity of Myostatin thus encouraging your body to build more muscle mass than it would under normal conditions.
History of YK11
YK11 was first studied by a Japanese researcher called Yuichiro Kanno in 2011. It is, therefore, a relatively new compound that is still under a lot of studies. Many unknowns are surrounding YK11 since it is still in its early phases of trials. For example, we do not know the long term effects, both positive and negative, of the chemical. The one thing that is guaranteed about this chemical is its ability to boost muscle growth.
Further studies showed that YK11 is a partial agonist of androgen receptors. The chemical has gene-selective properties, and that is why it functions like SARMs to deliver the desired results with minimal adverse reactions.
All the results of the limited trials concluded so far reported excellent outcomes in terms of muscle growth. Some trials have even reported YK11 helped bulls gain more than twice the normal lean muscle mass! Studies have also shown that YK11 has more muscle building properties than DHT! Yes, initial trials are showing that muscle cells are likely to become more anabolic when exposed to YK11 than when they are exposed to dihydrotestosterone (DHT)
Benefits of YK11
How does YK11 work to achieve the numerous benefits it is so famous for?
YK11 is a Myostatin inhibitor which merely means that it blocks the actions of Myostatin in the body. What actions are these? Here is the thing about the human body; we are designed to have some lean muscle mass but not too much of it. If you were to work out with no supplements at all, you would see yourself gain some muscles until you hit a plateau where there’ll never be any more muscle gain regardless of how hard you hit the gym. That’s your body’s mechanism of stopping you from having too much muscle mass that it cannot handle. Myostatin is the culprit behind this. The protein restricts your body from creating excessive skeletal muscles. While this is a good thing as it prevents muscle hypertrophy, it can be very frustrating for everyone who’s trying to put on some muscles.
Studies show that humans who have low levels of Myostatin usually have more lean muscle mass than guys with high levels of Myostatin. This was proved in animal studies. Also, individuals with mutations in their Myostatin genes are typically stronger and with more muscle mass than usual.
So, when you take YK11, it inhibits the activities of Myostatin thus getting rid of the barrier standing between you and bigger muscle tissue.
The following are some of the benefits of YK11 that have a scientific backing:
- Increases muscle tissue
YK11 is so effective in increasing muscle tissue that some users reported seeing results within the first week of using the substance! Other users have reported gaining between 8 to 15lbs of muscle mass after a complete cycle. This perfectly explains why some people believe that it is the most potent “SARM” available today. The beauty of it is that it doesn’t just deliver big muscle tissues, but it does so very quickly. Isn’t that every fitness enthusiast’s fantasy?
When YK11 gets into your system, it selectively binds to the androgen receptors in the muscle tissue. The compound increases the levels of Follistatin which will then block the production of Myostatin.
It’s important to note that none of the undesirable side effects associated with equally powerful steroids will be witnessed here. There won’t be any water retention issues, and neither will your balls shrink.
- It increases bone density
One of the reasons why your body is engineered to control the amount of muscle tissues you are gaining is due to the support that is required to sustain the muscles. For instance, if you are putting on pounds of muscles every week but your bones and connective tissues are unable to offer adequate support, it’s almost guaranteed that injuries and other health complications will be the order of the day for you.
To counter this issue, YK11 stimulates the production of healthier and stronger bone cells. It does so by activating protein Kinase B (PKB) which sends signals for increased growth of bone cells.
The ability of YK11 to enhance muscle growth also serves to strengthen the bones.
With stronger bones, the risk of fractures is reduced significantly. This should give you the confidence you need to work harder in the gym.
- Fat loss
YK11 is not the most potent fat burning SARM you can get, but it will still help you lose reasonable amounts of fat. The substance promotes an anabolic surrounding which encourages the burning of fats to produce energy.
Since YK11 increases muscle mass and boosts strength levels, the user will also break down more calories through their day-to-day workout sessions.
If you are planning on using this substance in a cutting cycle, we’d advise you to stack it with other SARMs for better results.
Side Effects of YK11
YK11 is an insanely powerful substance, and hence it is bound to have some undesirable effects on your body. Some of the most common side effects that you can expect from this substance include:
- hair loss
- acne breakout
- joint pain
- difficulty sleeping
- increased aggression
- may induce nausea and vomiting
Most of the above side effects will disappear once you finish your cycle. In some individuals, the side effects are merely a sign that your body is readapting to the presence of the new chemical. After a few weeks of using YK11, the body may get acclimated to the substance, and hence some of those side effects will disappear.
In some severe cases, YK11 may also raise your blood pressure slightly. The risk of this happening increase as you increase the dose. Also, individuals who already have a history of hypertension are at a higher risk of escalating the condition if they use YK11 and this is regardless of the dose taken. To stay safe, anyone with high blood pressure issues should remain clear of YK11.
YK11 is not just associated with steroids due to its powerful nature but also because of its structure. This is why some people are calling it a synthetic steroid. Due to the familiarity of YK11’s structure to that of steroids, it is believed that the substance may cause slight liver toxicity. It not yet clear whether this is 100% true due to the lack of sufficient human trials.
High levels of Follistatin have always been linked to a higher risk of contracting skin, stomach, prostate and esophagus cancer. The fact that YK11 inhibits Myostatin actions by increasing the levels of Follistatin in the body is therefore very worrying. Unfortunately, the lack of comprehensive human trials makes it impossible to tell whether indeed YK11 can directly cause cancer or not. This may be a long-term effect whose manifestation will start after years of using the substance. Let’s just hope that the ongoing clinical trials will clear the air on the matter soon.
There is also a possibility that long-term use of YK11 may result in gynecomastia, i.e. enlargement of male breast tissues. Gyno or “man boobs” as most bodybuilders call it can ruin your entire physique. Again, without enough human trials, it is difficult to know whether taking low doses or running shorter cycles reduces the risk of contracting the condition.
The working mechanism of YK11 is also bound to have some impact on the production of testosterone. This is an issue that has been reported by many users around the world. When testosterone production is suppressed, and you stop taking YK11, your body will become less anabolic. After a few weeks, you will notice that all the muscle gains you made are disappearing and fat deposits will start becoming visible. Low testosterone levels will also affect your sex life. For instance, erectile functioning will be affected, and your sex drive will drop.
The good news is that you can avoid all this by running post cycle therapy after using YK11. PCT is particularly crucial when you are dealing with substances as powerful as YK11. This therapy will restore the normal production of testosterone. The ordinary YK11 PCT usually uses Clomid (Clomifene) and Nolvadex (Tamoxifen).
YK11 is an extremely powerful substance even for men. Its usage in women can hence yield terrible complications. Some reports suggest that women suing YK11 may experience deepening voice, facial hair growth, irregular menstruation and deepening of the voice.
YK11 is quite a powerful compound, and hence its cycles are usually slightly shorter as compared to other SARMs’ cycles. Most people take YK11 for 6 to 8 weeks followed by a break. New users who are still experimenting with the chemical should stick with 6-weeks cycles. This helps in minimizing the risk of side effects. Experienced YK11 users can take the substance for slightly longer (8-10 weeks) and at higher doses.
YK11 can also be incorporated in other stacks which may run for slightly longer than 8 weeks. Personally, I would never use YK11 for more than 8 weeks, but if you feel like you must take YK11 for more than that, it’s best that you keep the doses very low. Taking YK11 for more than it’s necessary can easily result in severe testosterone suppression and liver toxicity which can lead to even more severe medical complications.
Every cycle of YK11 should be followed with post cycle therapy. PCT helps to restore all the damage YK11 will have done on your testosterone production. Taking a break from powerful chemicals such as Myostine will also help your body to resume normal functioning and restore normal hormonal levels before you start retaking the compound.
The amount of YK11 you should take will depend on many factors:
If you are a new YK11 or SARMs user, it is best to start with the lowest doses possible. Ideally, all new users should start with just 5 mg per day for the first few weeks before making a 5mg increment. If you already have some experience with using YK11 and other SARMs, you can start with 10mg per day.
Your fitness goals will also determine the doses you end up taking. The dosage required to deliver excellent bulking results is not always the same when it comes to cutting cycles.
YK11 dosage might also change if you decide to stack it with other performance-enhancing drugs. Make sure that you get the doses right whenever you are running a stack because the combination of several powerful compounds may become really dangerous.
With that in mind, experts recommend a dose of between 5 to 20 mg per day taken for a period of between 4 to 8 weeks. If you are a new user, you can start with 5mg per day for a few weeks, increase the dose by another 5mg, take your time to monitor your response and the results you are seeing before readjusting the dose accordingly. If you are responding well, you can increase the dose by another 5mg or even 10mg. This is how you’ll finally find your sweet spot. You should never take more than 20 mg/day though.
Due to tolerability issues and the risk of unpleasant masculine traits, women are usually advised to take much lower doses than the ones discussed above. The dosage should vary from 0.2 to 5mg/day.
There is minimal information on the half-life of this compound. It’s, therefore, a bit difficult to tell for how long a single dose will remain active in the system. Anecdotal evidence seems to suggest that YK11 has a very short half-life of 6-8 hours. Therefore, to achieve the best possible results, the user should split the dose into two. This helps in maintaining high levels of the compound in your system thus optimizing its performance.
Is it legal?
YK11 just like the other SARMs is in the grey area when it comes to the question of legality. While no laws are permitting the use of the compound for human consumption, there is also no law that is prohibiting its use. These substances lie in the gray area, and this has made it really difficult for the DEA and relevant authorities to control their distribution and consumption fully.
Most people, therefore, buy the substance under the disguise of “research purposes” but usually end up using it for bodybuilding reasons. If you are a scientist conducting some research, you should be able to get medical grade YK11 very easily.
If you are just interested in buying the compound for fitness purposes, then you can get it in excess from the internet. Unfortunately, the online SARMs market is unregulated, and hence you need to be careful about where you are sourcing the substance from. Remember that contaminated YK11 is not just a waste of your money, but it can also result in life-threatening complications. You can check out our list of some of the recommended online vendors of SARMs to make your shopping experience easier. You can also do your own research and visit the popular bodybuilding forums online to see some of the user reviews on these stores.
The one place where the use of YK11 is definitely not entertained is in professional sports. Stay clear of YK11 if you are a professional athlete lest the World Anti-Doping Agency and other sports governing bodies catch up with you.
Bodybuilding Uses of YK11
YK11 is a very powerful bulking substance. It is arguably more powerful than all the SARMs in the market at the moment. Some trials also claim it to be more potent that DHT!
The unique approach of this Myostatin inhibitor allows the body to grow more muscle tissues within a short time by preventing the action of Myostatin. The standard 8-week cycle can help you gain more than 8 pounds of muscle mass! Bear in mind that all this is achieved when using YK11 in a solo cycle so you can imagine just how tremendous the results will be if you were to stack it with another SARM.
An example of a powerful bulking cycle can include YK11 and Ligandrol (KGD-4033). Ligandrol is quite a potent bulking SARM in itself and hence using it alongside YK11 will only serve to deliver even better results in a much shorter period. In this stack, the user should take between 5-10 mg per day of YK11 and 5-15 mg per day of LGD-4033. Start low and avoid using high levels of either of the two compounds in this stack.
YK11 can also be stacked with RAD-140 (Testolone). This stack delivers excellent results, but it isn’t as powerful as the one discussed above. Here, you should take 5-10 mg/day of YK11 and 15-30mg/day of RAD-140.
- Protecting muscle tissues
It’s very disappointing to see all the lean muscle mass you worked so hard to gain disappear. This happens quite a lot especially when you are doing strenuous workouts that are cutting calories rapidly for extended periods.
YK11 provides your muscle mass with the protection it needs to withstand your rigorous workouts.
On its own, YK11 is not the best cutting drug that you can use. However, it is excellent in protecting muscle tissue, and hence it helps to keep your muscle mass intact throughout your cutting phase. It should, therefore, be used alongside other better cutting compounds like Cardarine.
It is also believed that YK11 may promote weight loss since it boosts muscle gains. This, in turn, breaks down more calories thus enhancing fat loss. The cutting impact here is very minimal though.
Performance enhancing drugs are the only way out of the genetic limit that your body sets when it comes to muscle growth. Once you’ve reached that limit, it won’t matter how many hours you spend in the gym or how heavy the weights are, but you will never go past the plateau. YK11 lifts this limit thereby unlocking unlimited muscle building potential.
Hopefully, more clinical trials will help in answering the questions surrounding this substance in the near future.
