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

Each bottle contains 30mls 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.

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.

Dosage guide for YK11 mixed at 15mgs/ml
Please note! these are maximum dosing guidelines and you do not have to dose at the maximum suggested daily dosage. Many customers will find lower dosing levels meets their needs without going to the maximum level and you are less likely to have side effects at lower doses.
The pipettes supplied with our products have graduated markings, with 1ml being the highest and marked down in 1/4 ml increments to make accurate dosing easy.
* 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.

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.

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/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.
