Narrows Labs YK-11 Suspension contains 20mg/ml and 30ml per bottle. YK-11 appears to be a super-SARM based on the reviews, while in reality, YK-11 is not a typical SARM. It is a new synthetic steroid based on 5-α-dihydrotestosterone (DHT) which is a stronger form of testosterone that targets androgen receptors in the prostate, sex organs, hair, and liver. YK-11 has gained a lot of interest in the bodybuilding world due to its potency and ability to rapidly build muscle mass with minimal side effects.

- Highly anabolic compound with fewer side effects than steroids
- Enhances muscle mass via myostatin inhibition
- Increases muscle building with fewer side effects than prohormones
- No estrogenic side effects
- No hepatoxicity so safe to stack with another SARM or prohormone
- Faster muscle growth than any natural test booster
- Much improved recovery
Who Can Use Narrows Labs YK-11 Suspension?
Narrows Labs YK-11 Suspension is strictly for males aged 21+ with a solid background of training who are now seeking to embark to a higher level of muscle mass and strength.
What Results to Expect from Narrows Labs YK-11 Suspension?
Positive reviews of Narrows Labs YK-11 Suspension report that it greatly increases muscle mass and its effects are seen in as little as a week. Some users report no side effects at all or very mild testosterone suppression. However, these claims are clouded by the fact that people use different dosages, cycle lengths, or stack YK11 with other SARMs.
Bodybuilders have experimented with YK11 in both bulking and cutting. Allegedly, YK11 is useful in bulking because it builds a lot of lean muscle in a short amount of time. Others have taken advantage of YK11’s ability to burn fat and harden muscles by using it in cutting cycles.
Narrows Labs YK-11 Suspension Side Effects
YK11 may potentially be toxic to the liver. However, some users reported doing blood tests during cycles of YK11 and initial results didn’t indicate abnormal markers of liver damage. We would recommend using liver support throughout your cycle.
Mild testosterone suppression has been reported. To be on the safe side, almost all bodybuilding resources recommend post-cycle therapy (PCT) after a cycle of YK11. Common PCTs include Nolvadex (tamoxifen) and Clomid (clomifene).
Other reported side effects include:
- Increased aggression
- Joint pain
- Low energy
- Mild testosterone suppression
- Hair loss
- Mild acne
Muscle Building with YK-11
YK11 boosts the growth of muscle cells by increasing follistatin levels, according to cell-based studies. Follistatin suppresses myostatin, a protein that normally stops excessive muscle growth. Anecdotal evidence from bodybuilders suggests it is effective at increasing muscle size. Users report lean muscle gains of up to 15 lbs and a decrease in body fat after a single cycle.
Is Narrows Labs YK-11 Suspension a SARM or a Steroid?
YK-11 is a steroid made by directly altering the chemical structure of DHT. In contrast, all other SARMs have a nonsteroidal structure. YK11 and SARMs work differently in the body and may have different side effects.
YK-11 has a very unique structure which shares more in common with steroids than it does with SARMs.
Because this class of drugs is so new, no established naming convention exists. Based on its activity and chemical structure, it may be more appropriate to call YK11 a synthetic steroid rather than a SARM.
How to Use Narrows Labs YK-11 Suspension
YK-11 should be cycled for periods of 4-8 weeks followed by a PCT as you would do with a prohormone cycle. Users of YK-11 should expect an easier recovery though compared to a prohormone cycle.
The most common dosage is 10-15mg/day. Users have also seen good effects at 5mg, which is a recommended starting dose for new users. Some people report doses as high as 30 mg with no side effects.
The half-life of YK-11 is 6-10 hours so the ideal dosing strategy is to split each daily dose into two. By taking two doses a day, YK11 levels should remain more stable, although there is no clinical evidence to confirm this.
