YK11 Guide: Results, Dosage, Cycles, & More! (Update 2020)
YK11 is quite possibly one of the most powerful SARMs on the market today, due to its unique nature as both a SARM and a myostatin inhibitor.
Not only is YK11 a SARM, which will help promote lean muscle growth, but it also inhibits myostatin, which unlocks your natural bodybuilding potential.
Is YK11 safe, however? What’s the best dosage for bodybuilding? What results can you expect to get? How long is a typical cycle going to be?
In this article, the Nanotech Team will examine the research and anecdotal evidence, to give you the facts, so you can make an educated decision.
What is YK11?
YK11 belongs to a class of research chemicals known as SARMS, which were initially developed to help treat muscle wasting in cancer patients.
Selective androgen receptor modulators, or SARMs for short, have potent muscle building effects, and are generally well tolerated in studies. [R]
While they were initially created to help cancer patients combat muscle wasting, bodybuilders quickly caught on, and realized that healthy individuals who took SARMs could experience steroid-like effects.
While there isn’t much clinical evidence regarding YK11, anecdotal evidence suggests it’s an incredibly potent muscle building agent.
In fact, as we’ll explore soon, lab rats which were given YK11 as treatment experienced absolutely mind-boggling muscle growth and results.
How Does YK11 Work?
Similar to other SARMs such as Ostarine, YK11 works by binding to androgen receptors in the body, signalling skeletal muscles to grow.
What makes YK11 unique however, is the fact that it is not only a SARM, but also a myostatin inhibitor, which gives it an added anabolic effect.
Your body normally produces something called myostatin, which limits how much muscle you can grow naturally—YK11 inhibits the production of myostatin, unlocking your genetic potential.
It does this by binding to androgen receptors and inducing the muscle cells to produce more follistatin, which inhibits myostatin production. [R]
To put it in layman’s terms, YK11 removes the “muscle growth limit” that your body places on itself—so that users can experience rapid gains.
While there are minimal YK11 studies regarding the effects on humans, we do know that this SARM has an extremely anabolic effect on animals.
In fact, mice that have low levels of myostatin, which is what YK11 inhibits, have on average twice as much muscle mass as rats who don’t. [R]
Here are some reported benefits of YK11 usage:
- Rapid Muscle Growth
- Increased Sex Drive
- Enhanced Strength
- Muscle Hardening
The biggest benefit of YK11 is the rapid muscle growth, as users often report gaining 10-15 pounds or more from one 12 week cycle of YK11.
Unfortunately, there have been no studies done with YK11 on humans, so all of the results and before and after pictures we have are anecdotal.
That being said, many users who log their YK11 results on Reddit and other bodybuilding forums report gaining up to 20 pounds from a single cycle.
Most users who take a YK11 cycle report gaining massive amounts of muscle, and many believe it’s the strongest SARM on the market.
The reported effects of taking YK11 are rapid muscle growth, enhanced strength and performance in the gym, and increased muscle hardening.
Dosage & Cycle Guidelines
Because there have been no human trials with YK11 treatment, there is no medically established dose of YK11 for human use to date.
However, the general consensus amongst body builders is that 10 mg is a good dosage for muscle growth and performance enhancement.
Here are the YK 11 dosage guidelines:
- Beginner Dose: 10 mg per day
- Intermediate Dose: 15 mg per day
- Advanced Dose: 20 mg per day
While some users have reported taking dosages as high as 30 mg per day, most agree that taking between 10 mg and 15 mg to start is best.
SARMs are often dosed in mg/ml, so to take a dosage of 10 mg per day would be equivalent to taking one full dropper of the YK11 from Proven Peptides.
YK11 Bulking & Cutting Stacks
Most body builders agree that taking YK11 for bulking is best, although it could still be used in a cutting stack to prevent losing muscle mass.
|Sample Bulking Stack||Sample Cutting Stack|
|YK11 – 10 mg per day||YK11 – 5 mg per day|
|Ligandrol – 10 mg per day||Ostarine – 25 mg per day|
|RAD 140 – 15 mg per day||Cardarine – 10 mg per day|
Due to its effectiveness as a bulking SARM, YK-11 often pairs well with RAD 140 (Testolone) for a dry bulk and potentially Ligandrol for a wet bulk.
YK11 Side Effects
Because there are no studies regarding the safety of YK11 use in humans, most of the side effects reported are from body building cycle logs.
Some users report zero side effects in the short run, and some report many side effects—so the short term negative effects of YK11 will vary.
Here are some potential side effects of YK11 use:
- Testosterone Suppression
- Mild Liver Toxicity
- Joint And Tendon Pain
- Increased Aggression
The most obvious side effect of YK11 use is testosterone suppression, but this is common with all SARMs, from Ostarine to Ligandrol (LGD-4033).
Side effects of YK 11 can be mitigated by taking supplements on cycle for tendon pain and liver support, and by doing a proper PCT, as well.
To summarize, YK11 is a powerful myostatin inhibitor which can lead to rapid muscle growth and increased strength in users who take it.
While it isn’t approved for human use by the FDA, many body builders choose to take it regardless, for the performance enhancing effects.
