Both SARMS are expected to produce

  • Accelerated fat loss
  • Rapid strength increases 
  • Visual vascular improvements
  • Stamina to complete more work
  • Weight gains of purely of lean muscle tissue
  • Complete Recomposition of tissues in a featured subject

However, yk11 results in an ability to grow beyond genetic potential.

All SARMS increase aggression, although none quite like these two.

The difference is the s23 SARM cycle is the most potent standalone.

When it comes down to what works best the Lgd yk11 mk677 stack#1

YK11 vs Rad-140

Although many consider yk11 to be a synthetic steroid, it's effects are more from the increase follistatin expression that causes insane muscle growth.

On the other hand, rad-140 is already in human studies; it is not toxic to the liver and lacks insofar as anyone knows any side effects.

Users also report the combination of several selective androgen receptor modulators (SARMS) will build lean muscle mass faster.

So there you have it stack yk11, build muscle and research the effects that synthetic agonist of the androgen have.

    YK-11 is amazing, noticeable strength increase, noticeably dryer hard looking gains and seems to attack belly fat. Ive done research with up to 50mgs daily and results had only gotten better

    week 3 going on 4 at 56mg a day! Of yk11, so far.... everything is great! I’ve really noticed increase of strength and endurance literally reps for days with this stuff! And I’m down 15 lbs.... although loss of weight is not the goal it’s welcomed! I can’t wait so see how the next three weeks go! And I will continue use throughout the full duration of my cycle! This product is absolutely unreal I recomend it as a addition to any cycle or even a stand alone compound!

    What dose should I use for best results and how many times a day should I be taking it? As well, would it be relatively safe to stack it with sr9011?

    Apr 27, 2019, 15:57

    There are no contradictions with SR9009 and YK-11, researching them both at the same time poses no hazards.
