My energy levels have definitely been down over the course of the last year. Here is my experience with these supplements
– Feeling much more balanced mentally.
– Physically more sustained energy in my everyday routine and workouts.
– Maintaining muscle mass and leaning out.
The most important thing for me was that there have been NO negative side effects and I feel as though my sleep quality has improved. Very happy customer.
atharv –
Love them makes me feel good
amiri –
These supplements actually works. I’ve tried many many other products over the years and this one stands out above them all. No side affects that I have noticed. It works over time and builds up within your body. My strength is increasing and muscle mass has noticeably increased. My overall feeling of wellness has really improved. I will continue to use this product for sure.
alfred –
Originally bought these supplements to help with my workouts. At first I was a skeptic; however, after about a week I started to notice improved muscle response and recovery. Also, there was a added benefit in the bedroom. I’ve been the product for several months and plan to continue using it, it works.
teddyhenry –
The main reason I was interested in taking this supplement stack was to increase my energy, and it worked! I no longer suffer from the afternoon lull in energy that I have been experiencing lately. I also feel it has helped with my metabolism because I have lost about 5 lbs. since starting supplement. Highly recommend!
ezraisaac –
I am starting to notice a difference in my stamina. I think that this will be a good supplement stack to continue taking. Others that I have tried upset my stomach or made me dizzy/heart race. This one is just the right combination for me!
hunter –
It’s exactly what I ordered. I like everything about the ingredients that it has in it to the way I’ve felt over the last few weeks.
carter –
I do get a boost of almost immediate energy.
john –
I was looking for something to give me a little extra boost of energy, improved recovery, and some cognitive benefits during the day and after reading other reviews decides to give these a try. About a half hour after taking my first dose I started to feel a difference in my energy levels, I’ve been taking them for 2 weeks now every day and I can say I’ve never felt better. I’ve been cutting down on my caffeine intake because I feel as though I don’t need as much of it anymore. I would definitely recommend this product, on top of feeling more energized my mood has been considerably better as well and I my brain is less foggy than it used to be in the mornings.
graysonisaac –
I have tried probably 4 different brands before Apex Receptor. I must say this one works the best for my muscle growth and strength.
gabrielanthony –
Great product! It works!
jaxon –
This is an amazing supplement. It really works. I have been taking it for almost 5 weeks. I only take 1ml on each in the morning and have definitely felt more energy and really focused at my head-down job. These results are quite impressive. The increase in energy is not like thrilling but it’s significant enough to notice and feel. The two most noticeable benefit with this product was the physical energy and emotional motivation. I will continue to take this product. I believe it will get better and I will see more improvement. I strongly recommend.
lincoln –
Good for an extra boost during the day
joshua –
I use the MK-677 and RAD-140 because when I would get my chemo I felt tired and didn’t really feel like doing anything, but with these I have the energy that I had before I was on chemo. Also, I’ve noticed a little improvement on my focus and mental clarity.
I’ve tried other brands, but I would get constipated & have a bad feeling in my stomach after taking it. With this Apex Receptor, I don’t feel any of that, only a little extra energy during the day.
I would recommend this brand over the others.
lucius –
You ever passed out right in front of your desk at work before? Unfortunately, that’s exactly what I had been experiencing for a few weeks so I decided to do something about it. I needed strength but I’m not a big coffee drinker plus I usually crash from it. I did some research and found out about these products. Well now with 2 drops a day, it’s been nearly 3 weeks and no more falling asleep at my desk!
If you’re looking into getting a good source of clean energy, I highly recommend it!
christopher –
Good strength boost by Beginner Stack – Mass Bulk at a reasonable price!!
andrewryan –
I am so happy that UK SARMs carries these amazing supplements! They help me so much in my day to day life. I feel focused and energized. I accomplish so much during the day. I will continue to advocate for this company and for their product. Thank you, UK SARMs for being a provider of this product!
thomas2 –
Was looking for a supplement to boost concentration and energy level, and wanted to give MK-677 and RAD-140 a try. I now consistently take one in the morning and one in the afternoon and it gives me a sense of calm energy so I can carry on my day without getting tired. Overall I highly recommend this product and UK SARMs in general for a boost of attentiveness and consistent concentration throughout the day.
isaiah –
The bottle isn’t too big and can fit easily in one hand. These supplements are great on their own or when pairing with each other. They don’t have an awful taste and that is just fine with me.
hudson-8617 –
I really love the extra boost of energy that I feel after taking these! I take 1ml on each every morning with my breakfast and feel at the top of my game without experiencing the jitters that I used to get from coffee. I also find that it helps me stay focused when working for long bouts in front of my computer. I chose the Apex Receptor brand because it is made in the UK and is manufactured in a GMP Certified facility – so I know that the quality is there. Highly recommend and would purchase again.
hudson-8617 –
Effective supplement for strength, improved focus, and mental clarity
connor –
I’ve used Beginner Stack – Mass Bulk for 30 days and can confidently say that I feel a difference in my overall energy, mood, and focus. Being a 25 year old male, I was looking for a supplement to give me the drive to complete tasks such as extensive workouts and business assignments. This product definitely gave me the drive and patience to push through some of my most difficult exercises and assignments on a day to day basis. I recommend this to anyone that wants a natural edge & boost of energy and concentration. Consider me a happy customer.
jonathan –
I have had problems taking pills, even small ones. But with these kind of supplemnts, I feel it very easy. No flavor and they do not trigger any rejection for me.
I’ve been taking them for more than a month and definitely feel much better overall. I can’t compare it to days when I haven’t had them. I definitely plan on continuing with them!
nolan –
I had low energy at 60 years of age. With these I have noticed improvement in energy levels, improved recovery, muscle development, and enhanced endurance. I recommended this to a co-worker who needed the strength to keep going. He has heard good things about it and plans to order ASAP. This REALLY works!!!
jeremiah –
It seems to help my memory and focus.
colton2 –
I’ve used this for about 3 weeks, and I have noticed that I have more energy through the day and improved recovery during my workout.
cameron –
These are good quality supplements. The order arrived quickly and was as described. This Beginner Stack – Mass Bulk didn’t have any side effects that I noticed and were easy on my stomach when taken with or without food. I noticed increased energy during exercise after a couple of weeks of use and intend to keep using this brand.
Overall highly recommended supplement in a crowded market.
carsonrobert –
I was taking a different bulk stack and wanted to give this a try. No side effects that I have noticed. I have more energy throughout the day and in the gym. Mentally I seem to be more focused and have better recall. I have also noticed improved recovery time and fat loss function which is always welcome! Will buy again.
jules –
At my advanced age, I found myself sitting in my easy chair daily and not having initiative to do even the smallest tasks. Since taking MK-677 and RAD-140, I have regained enough of my focus and drive to be able to stay active and do a few tasks like tree pruning and other small jobs.
maverick –
This Mass Bulk stack is the real deal! The high potency ingredient is incredible. I have taken products in the past, from other companies, at less mgs, but they don’t compare to this. I have been using this product for approx 6 months. (25mg /day on each). Better energy, stamina, alertness, concentration and recovery. Excellent results from a fantastic, quality product at a great price.
nicholas2 –
I bought this to see if it could assist with mental focus. After a few months I experienced no side effects. I also see some improvements in stamina or energy.
dominic –
I take 2ml in the morning on an empty stomach and after about 15 minutes felt an “awake” feeling. I’ve noticed increased strength and I would recommend giving this a try. The strength gain is worth it.
jaxson –
I know everybody is different and something might work for some and not for others but I have to give these supplements a 5 stars rating! I am a 52 years single male and had lost all kinds of interest in physical activities due to lack of energy and motivation. The two most noticeable benefits with these supplements are the physical energy and mental motivation. I started back at the gym after over a year and felt great. I have been recommending supplements supplied by UK SARMS to all my friends and family.
greyson3 –
I have tried other mass bulk supplements before and felt like I never really felt a difference from them. This supplement from UK SARMs definitely gave me the boost of energy, motivation, and clarity that I was looking for. Definitely recommend taking this to anyone interested in bettering their cognitive benefits.
luke –
This is the stack I’ve been looking for!
I started off taking one ml on each product every morning and started to notice that instead of thinking of my to do list, I actually got up and just did it! Felt so good.
santiago –
I discovered Beginner Stack – Mass Bulk a few months ago. I like this supplement as I feel energized every day. It seems to help me stay focused throughout the workday. I have tried other products but now feel I have found one which actually results. I hope UK SARMs will continue to carry the product and it will always be available for me to purchase.
jordan –
I recently came across the benefits of Beginner Stack – Mass Bulk and did a bit of research on the products. After consumption, I can definitely feel the energy I need for my hectic day to day activities at work including travel. Great products and I intend to continue with the same dosage in the future.
cooperbrayden –
Absolutely great and it’s easy on my stomach. Thank you
evan –
It really works! There is noticeable difference in energy and productivity!
reid41 –
Honestly I think it’s obvious that you need to work out while taking any supplement along with proper dieting. I go to the gym 5 days a week and when I workout I go after taking these then my pre-workout. I didn’t feel anything negative and I personally could see the changes and lost a lot of stomach fat. Will continue to use after the resting cycle honestly.
Very pleased.
clark67 –
Can tell my workouts get more intense, I can feel the heat in the muscles as I workout!!
erik –
These products are easy to take and I put on a good bit of muscle mass. Been taking for almost 2 months. It does make me sweat a bit with the fat burning properties. It’s a good buy. Strength is up. But it’s not a magic product. You still have to eat decent and work out.
lawson44 –
I personally gave up on workout supplements when I started bloating easily even with my guided workout routine but Beginner Stack – Mass Bulk came recommended and I wanted to give a last try to its kind. I ordered a bottle and liked its smart packaging and tamper-resistant sleeve thanks UK SARMs. The comprehensive blend is effective and easy to take without any aftertaste made this product more appealing and convenient. So far, I’ve noticed that I’m more alert and productive throughout the day, which is a welcome change from the occasional brain fog I used to experience, and there has been no bloating since I started taking it. Also, I am visibly experiencing a more defined physique along with my workout routine since I started using it. These supplements are sure to provide a noticeable boost to your overall physical health and well-being. I’ll be ordering a refill, and highly recommend giving them a try.
trevor –
Perfect supplement! No issues, as they advertised get results as you want. Im getting ready to buy another bottles. Best product money can buy. 5 star rating.
gage4 –
The energy and endurance boost from these supplements is incredible. I power through my workouts and recover faster with much less soreness. I also appreciate that both products have effective ingredients, so I don’t have to worry about side effects.
nico2 –
Excellent product, unique quality, a great and performance product for those who regularly work out in the gym.
malakai3 –
Best quality supplement on market. You feel the heat from the inside out. If your looking for building muscle mass and strength while getting ripped, cut and shredded, then this is what your looking for. Strength gain, muscle gains and weight loss during your workouts. Exactly what I’ve been looking for and will buy again and again. Very effective.
quinn –
As an avid athlete, I found these products to be effective and easy to use. I had increased strength, cut, and a better mental health.
Jake Hayes –
Easy to consume. Weight loss and energy results within the first few days.
Manuel Prince –
Over the week of continuous use, I noticed an increase in energy and possibly an improvement in my mood. While I don’t expect a complete body transformation after just one bottle, I’m curious to see the results after a full month of continued use.
Bodhi Cohen –
Great. It gives my body the energy I require
Sean Khalil –
Great for energy. No jitters.
Hendrix Derek –
These are the supplements that do what they say they will do, enhance your metabolism and give me the energy and endurance I need to go on with my workout.
Cristian Cruz –
Definitely felt a boost in energy, endurance, & stamina. Will update this review if I detect or experience any discernible effects whether positive or negative.
Kairo Dante –
I’ve begun taking these supplements for extra energy and hoping it will cause some weight loss. So far they don’t agitate my stomach or cause me any sensitivities. Im hoping in the longterm that they perform well. So far so good.
Atticus Killian –
I started using these for my weight loss. I have lost over 100 pounds and still have about 90 to get to my goal weight.
Stephen Orion –
Definitely noticed a difference in my energy level. I highly recommend it.
Malakai Ali –
No flavor to me. Taken with a juice and didn’t upset my stomach.

Boosted Energy Without the Jitters
Spencer Gideon –
This stack has been a game-changer for me! It gives a noticeable energy boost during workouts and helps with endurance. I also feel it’s supporting my metabolism and lean muscle goals. Easy to take and a part of my daily routine now. Highly recommend it for anyone looking to level up their fitness game!
Mario Titus –
One of the few weight management stacks that has worked well for me.
Travis Rylan –
Loving this stuff. Good addition to my workouts. It has helped me with not only fat loss but with energy to get through my workouts.
Kayson Ricardo –
Very good product, you don’t feel discomfort when taking it and it helps a lot with my workout. It works.
Tanner Malcolm –
This fat burner and hard body recomposition work powerfully. It’s no joke, and I think it’s important to use this mindfully. It supports weight loss goals, but as with all fat burners, its support occurs as a helpful addition to an already established baseline low-calorie diet, exercise routine, and restful night sleep. It works!!!
Raymond –
This is the first stack I’ve taken and I have seen noticeable results fast. I live an active lifestyle but have been struggling to shed those extra fats. In just one week of taking these, I have lost around 7 pounds. They also keep me energized and I have noticed a boost in my mood lately — highly recommend.
Cesar Lennox –
It gives me the boost I need to start my day!
Joaquin Kane –
I strongly recommend this product to anyone who is seeking to improve lean muscle mass and decrease the size of fat cells. I feel like Beginner Stack – Mass Bulk assists me greatly with reaching the results that I’m seeking along with a low-fat diet and exercise.
Wade Muhammad –
Excellent product. I am happy with the purchase, and I recommend it!
Iker Jaylen –
Love the kick start of energy to my day – helps maintain my stamina and endurance. I’ll buy this again and again.
Crew Zayn –
I love the stack!
Hector Ellis –
I decided to take back my health for my family. I want the time I have with them to be great…and my health is a huge factor. I started eating better and adding exercise to my daily routine. No issues or other negative side effects
Leonel Cairo –
Helpful and I could feel that extra energy boost. Time will tell if it melts off the fat of course, but so far so good.
David H –

Felt benefits within a few weeks, far better than the rubbish being advertised out there the minuite.
Ryan –
I’ve been using this stack for around six weeks now and I can genuinely say these two together are brilliant for quick gains.
Zac Thornton (verified owner) –
I was very sceptical as there isn’t much direction on dosage now as a beginner using droplets sarms I was unsure so if any one would help me if I’m over doing it that will be great, I am doing on line on the pipett once a day? All in all I do feel great and my workouts are getting hell of a lot better feel stronger already
