Buy ALPHA (YK-11) From Uksarms

UK SARMs – ALPHA’s active ingredient YK11, is one of the most advanced SARMs currently available on the market. It is a one of a kind substance that works to inhibit Myostatin while working as a SARM at the same time (Selective Androgen Receptor Modulator). Myostatin is a protein which inhibits and limits muscle growth. Alpha works by binding to Myostatin which allows for one to build muscle beyond their genetic potential.

YK11 induces muscle cells to make more follistatin (more than DHT does) – a strong myostatin inhibitor.

  18. Liam

    Never seen such improvement before. Determination and strength is at an all time high!

  19. Pete

    Throughout the cycle my bench increased 40 pounds, squat went up 60 pounds, and deadlift went up 70 pounds!

  20. Theodore

    From week 3 onward my strength went up like crazy ????

  21. William

    My frame seems a lot bigger, especially my shoulders/chest/back, and my legs got a lot thicker. Overall it’s probably the best SARM I have done, nothing has increased my strength like YK-11, and it helped me pack on a lot of muscle.

  22. Jamie W

    Bench had the most notable gains. Going from 255 as my max to 315 and did 295×3 today. Amazing product.

  23. Roland

    In 8 short weeks I went from chubby to ripped ????

  42. William

    Amazing customer service, swift response and I received my order a few days later that same week????????

  43. Jamie spen

    I’ve used this for about 6 months and tbh am feeling alot better in myself, more energy and stamina and has helped a lot to tone up.

  44. Gaz

    Definitely a must buy product

  45. Ricky

    Gr8 product!!!

  46. Tony

    Within a week of using I felt I was becoming more toned. After a month I could really see and feel the difference in my mass, my recovery times had reduced an I was able to increase my weights confidently without being concerned about injury. I would definitely recommend this product which came with no side effects.

  47. Daniel

    Item gets a 5 star rating from me, for the price you pay the results are fantastic if you make the effort for the product it does work! I take it on a morning before anything else and consume plenty of water during the day as it makes you very thirsty anyway. No side effects at all so nothing to worry about. Does exactly as it says and for the money worth a try.

  48. Umar

    These guys are ready to answer any questions that you have. Prompt reply. Excellent.
    Use this along with creatine and good amount of protein you will see results

  49. Scott

    Great product, fantastic seller. Saw amazing progress along side my normal gym work outs, does exactly what it says on the bottle. Seller gave fast shipping so was here In time for the work outs. Easy to use product with clear instructions on the bottle.

  50. Simon Drake

  57. David

    it worked for me in that i gained 7lb of muscle in just over a week.it sort of made me aggressive at first but i started to wonder if it was this product that was making me sleepy.I’m going to get some more though,can only get better

  58. Idriz

    Good stuff does the job ordering more

  59. Reggie

    I tried it and it works. Don’t expect results in one week. You have to ust the product and train. A product like this is useful when used as directed. You will see the results!

    Have to say that it works. Am into fitness, but I’m no bodybuilder. But this thing has helped shape a 43 year old guy out of the blue! Started using different supplements on and off over the last 5 years. This is probably the only one I have seen giving such an improvement. Well impressed! I’ve worked out 5 days a week consistently for 3 weeks, looking after my diet big time too. And the results are there to see! One happy bunny!
