    Overall very impressed with sarmtech products. This YK-11 was very potent – much more so than my first purchase which was blackstone , found on ebay … not even sure if there product did anything. Capsule qty is 90 vs 60, which is also great. This was shipped out same day and arrived in 2 days too.

    Great product except i ordered YK11 but got RAD140! The rad experiment is very strong though and I got the better deal

    UPDATE: I emailed James at Sarmtech and they immediately sent me a bottle of YK… 2nd day air! I can’t update the stars but if i could i’d give you guys 6!!

    Test subjects noticed increase in muscle fullness/hardness, decrease in body fat, increase in appetite, some subject had mild hair loss, increase in strength, and an apparent decrease in natural test. Highly recommend pct for test subjects but all mild side effects were reversible during pct. a size and bulk research chemical that is top notch from sarmtech.net thank you for existing guys!!!

    Great product! Subject has been feeling good. More reps less burning in muscles. I could see results in subject after 1 week 1/2 of use (with proper diet)
    Side effects encountered :
    – A little bit of joint pain but nothing alarming
    – hair grows faster
    – aggressivity & more sensitive the first 2 weeks of use
    – More hungry
    Next purchase will be yk stack with Lgd.
    Love it so far!

    Purchased with FreeUp testosterone booster. Subject experienced bigger gains in muscle with this than was getting with LGD. Researched with both of those sarms separate and saw very good results. Researched them on second cycle stacked together and subject gained same amount of muscle in one week than did in 4. Wow!

    The yk11 has been a great addition to my sarm stack. Subject is 52 years old feeling great. His testosterone levels are high and has gained 12 pounds of muscle in a month, sometimes works out twice a day. Subject eating like a beast and feels like a bull.

    Seems to be an excellent addition to stack with LGD, enhancing the strength gains. This is the subjectss 1st stack with YK11, after using LGD alone for several rounds. Will try to add in on other cycles.
