Hardcore SARMS USA, YK11

15mgs/ml of YK11 for Muscle Growth beyond Genetic Limitations


Each HCS YK11 bottle contains 30mls (1 fl oz) and includes a 1ml pipette that is marked in 1/4ml increments for easy oral dosing.

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.

HCS 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.

* If you have not taken this product before, we suggest starting out on half the recommended daily dosing for the first week before moving up to higher dosing levels. Please do not dose higher than the guidelines below.
* If you notice any extreme side effects, stop taking the product immediately and discontinue use.
* If you have any minor side effects, lower the dosage by a half and if the minor side effects don’t cease after a week then cease taking the product.

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/throat. This can be followed by a drink to help diffuse the taste.

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.

HCS YK11, a compound known for its remarkable potential, is revolutionizing the field of muscle growth with its unique mechanism. Through the precise interaction between YK11 and Myostatin, a protein responsible for limiting muscle development, this impressive substance allows individuals to surpass their genetic limitations when it comes to building muscles. By binding directly to Myostatin, YK11 effectively inhibits its effects on muscle growth pathways within the body.

Consequently, this inhibition provides an unprecedented opportunity for users of HCS YK11 to tap into untapped potential and witness substantial gains in muscle mass that were previously considered unattainable through conventional means. As athletes and fitness enthusiasts strive towards achieving their personal bests, YK11 emerges as a powerful ally capable of unlocking a realm of muscular growth beyond genetic boundaries.
