YK11 works by binding to Myostatin, inhibiting its effects, which allows muscle growth beyond genetic limitations.

YK11 is the most advanced Myostatin inhibitor currently available on the market.

Myostatin is a protein which inhibits and limits muscle growth.

YK11 is ideal for those that have been training hard and have reached a peak where muscular growth has plateaued.

Needs to be taken with another product that stimulates muscle growth, like LGD-4033 or RAD140 as YK11 does not stimulate muscle growth (contrary to what a lot of people on the web say). YK11 specifically blocks the myostatin from inhibiting muscle growth allowing the muscle to continue growing again.

YK11 side effects
There is a degree of testosterone suppression with YK11, and clinical recommendations are for male researchers to run a PCT cycle that includes Nolvadex or similar to normalise testosterone levels at the end of a training cycle.


The average dose is 1ml per day for males and 0.5ml per day for females. So women need to halve the dosages mentioned below.
Take YK11 at the same time each day including non-training days.

YK11 is taken twice a day as two 1/2ml daily doses, 1/2ml in the morning and 1/2 in the evening, however some customers find their muscles get too hot in the evening when dosing this way and can find it difficult to sleep particularly in summer time. If this occurs then dose once a day at 1ml in the morning.

Each bottle contains 30ml, providing 30 days of use for males and 60 days for females.
Cycle length: 8 to 12 weeks.
Rest between cycles: 4 weeks.


How do I take this SARM?
This product is an orally active compound, so for best results it should be squirted into the back of the mouth. After about 10 seconds it will have been totally absorbed into the throat providing almost 100% bio-availability. This can be followed by a drink to help diffuse the taste of the polyethylene glycol base.

If the taste of this SARM is hard to handle or it irritates the throat, the product can be squirted into a protein shake or drink and swallowed but this reduces its bio-availability. So it’s not a choice we recommend.
