UK SARMs – TEST (RAD-140) is perfect for cutting as it promotes lean tissue gains and the loss of body fat, and can also be helpful in preserving muscle tissue with its anti-catabolic effects.

UK SARMs – GAIN (LGD-4033) has the ability to increase strength levels, lean muscle mass, encourage a drop in body fat, has healing properties, and does not cause the undesirable side effects caused by bodybuilding supplements.

UK SARMs – GROWTH (MK-677) is an orally administrated GH secretagogue. A secretagogue is a term for a substance that naturally signals the pituitary gland to secrete Growth Hormone.

UK SARMs – PUMP (S-23) is a product that has a strong binding affinity to Androgen Receptors in the body and therefore produces similar results to injectable anabolics. As a SARM it is the strongest SARM and as a result currently the closest available SARM to anabolics.

    After years of using other brand products that said would work but didn’t , last year I decided to use uksarms! Best decision I made, you get what you pay for and uksarms lives up to its claims and worth every single penny .. if cost is a factor than your not serious enough to get your goals simple!

  89. Matteo

    All I can say this stuff is Fantastic

  90. Joseph

    Yeah, im really pleased with this, it really does what it says.

  91. Daniel

    after 2 weeks, Massive Increase in Strength. Wow.

  92. Freddie W

    Been taking this for about 4 weeks now. I noticed a massive increase in strength after just 1 week. I managed 12 reps on bench press with the same weight i previously struggled with for 8 reps the week before, and i had been stuck on 8 reps for quite some time (wasnt a fluke, because i have continued to gain more strength since). Generally felt all my muscles harden up and define slightly after 1 week and feel great during weight sessions and felt a general sense of well being.

  93. Christopher H

    After 4 weeks, strength has continued to increase a lot.size wise, i have definatley made gains and have put on nearly half a stone. my size hasnt increased hugely, but strength is definatly the most notable.

  94. Cameron

    Noticed a difference right away, was able to do more work at the gym literally overnight.

  100. Mark

    I’m doing dead lifts and squats with just over 60kg now where b4 I struggled with 40kg ! They certainly help with that last push as well

  106. Tate

    I can see and feel the muscle size within 7 days

  107. Kevin

    I was very sceptical when reading about this product and was very wearey about ‘value for money’. However, i’m now in my 3rd week and im making substantial gains, very happy with the results i’m achieving. I started to notice results towards the end of the 1st week

  108. George

    I’m continuing to gain and I no longer have to struggle to get myself down the gym, I actually look forward to going now.

  109. Mike

    Amazing stack – using this and completing 3 intense kettle bell work outs each week for the last 2.5 weeks has made a big difference – will definitely be purchasing again as this helps me get the maximum out of each work out!

  110. Wesley

    What can i say, this stack is the first stack i have used and it has improved my overall strength in the gym, i have noticed i can push more weights and pushes me further when i want to quit. Great!

  111. Jake

    Increase in strength and power within 2 weeks

  112. Matt

  120. Bradley

    I can feel the difference in pure strength and power but yet to see ‘big’ results in the way I look, there is a difference however…good stack overall

  121. Christian

    As a fitness and nutrition Instructor I am always a bit warey of product claims but I was pleasantly surprised to say you can actually feel this product working within a few days your strength increases and within 2 weeks I had added muscle my back in particular grew and my legs I was mainly compound movements bench press, dead lifting and squatting more and my bench increased by over 10kg

  122. Bailey

    Seen small gains. But better gains in strength.

  123. Tim

    I can really feel a difference since taking this product. Already in 3 weeks I’m lifting heavier weight and doing more reps. My body looks and feel great, feeling less tired in the gym means I can do a lot more. Muscle definition is really starting to show and muscle growth has increased.

  124. Carlton

    I was a bit pessimistic when I first bought this product as There was a lot of mixed reviews some people saying a waste of money and other people saying how good this product is. After using this product for two weeks now I must say I am very impressed not as much as size but sheer strength my benchpress has gone from 160 up to 180 KG which in my eyes is a big jump in just two weeks. And all my Main lifts have also increased at least by 10%. Keep your diet clean and train hard and you should get the same results. So its a big thank you to Uksarms!!!

  125. Clyde
