Best SARMs For Bulking: Our Top 4 Picks And How To Stack Them For Best Results

The scientific community has long known that muscle mass is one of the biggest contributors to athletic performance. According to a study by Timothy J Suchomel, greater muscular strength increases performance while also lowering the rate of injury in athletes.

SARMs are without a doubt one of the fastest ways to gain muscle mass without dealing with the dangerous side effects that can come with the use of anabolic steroids. No wonder so many athletes are using sarms for bulking!

In this article, we’re going to list the best SARMs for bulking and gaining muscle. We will also show you two different stacks and explain the benefits of each one. By stacking sarms together, you can reap the benefits of multiple compounds at once.

The first bulking stack is for beginners and is recommended for those who are new to the world of anabolics. The second one is for the extreme athlete who wants to gain the most muscle mass in the least amount of time.

The four best SARMs for bulking / gaining weight

Bulking SARMs

By definition, all sarms can be used for bulking and gaining muscle mass. With that being said, there are four in particular that are optimal for gaining mass. Here are the top four SARMs for bulking:

LGD 4033

LGD 4033 is a must have for any sarms bulking cycle. Out of all the available SARMs out there, it remains the most popular option for building quality muscle mass. It drastically increases protein synthesis, glycogen storage, and blood flow. You will experience bigger pumps, longer workouts, and a faster recovery time. Best of all, LGD 4033 is one of the more inexpensive sarms on the market. There is no excuse to not be using it in your stack if you are bulking.

YK 11

Next on the list is one of my personal favorite SARMs for bulking. YK 11 is a real myostatin inhibitor. Simply put, YK 11 forces your body to build muscle mass rapidly. I’ve said it before and I’ll say it again: YK 11 is strong stuff. If you’re serious about transforming your physique, you’ll want to use this SARM in your stack.

RAD 140

RAD 140, also known as testolone, is the strongest sarm available for sheer size and strength gains. It also has the highest risks for side effects when compared to other sarms. Be careful with this one if you choose to include it in your stack. A good starting dose is 5mg, and you can go up to 15-20mg if your body tolerates it well.

MK 677

It’s commonly known that bodybuilders use human growth hormone to pack on insane amounts of size and strength. The problem with HGH is that it’s extremely expensive and needs to be injected frequently. MK 677 is your ticket to drastic increases of HGH. It is an oral solution that produces the same exact spike of growth hormone that real HGH does. It’s a fraction of the price as well. MK 677 has the added benefit of promoting quality sleep and also giving you better hair, skin, and nails.

Important tips about bulking on SARMs


Before you begin the sarms bulking stack, there are a few things that you need to address. SARMs will increase muscle regardless of what you do, but you won’t get the most out of your cycle unless you take care of the basics.

Fix Your Diet

Diet is arguably the most important aspect of a successful bulking cycle. This is true whether you are using SARMs for bulking or if you’re just trying to improve your physique. A good diet for bulking will include a high caloric surplus and an adequate amount of protein. Here are some tips for keeping your diet in check while taking the sarms bulking stack:

  • Keep that protein intake high. Don’t get less than 1g per pound of bodyweight. If you weigh 185lbs, you need a minimum of 185g protein per day.
  • Drink at least one gallon of water per day. Hydration is key for building muscle and metabolizing SARMs. Do not let yourself get dehydrated. If you’re thirsty, you waited too long to hydrate.
  • Eat your biggest carbohydrate containing meal shortly after you workout for the day. The SARMs bulking stack will help shuttle those carbs into your muscles and leave you feeling pumped all day.

Workout Routine

In addition to cleaning up your diet, you also need to make sure that your training routine is optimal for gaining the most amount of muscle mass possible. While any work in the gym is better than no work, there is certainly room to maximize the results that you will get with sarms.

We have found that high volume and high intensity workout programs seem to work the best for bulking on sarms. You want to make sure that you take advantage of the anabolic state that your body is in while you were on this stack. If you are lazy with your training, you will not see the games that you desire. Here are a few different workout programs that we recommend while using the stack:

  • German Volume Training
  • Stronglifts 5×5
  • Classic PPL split (Push, Pull, Legs)

The SARMs beginners bulking stack

Bulking Stack (Beginners)

If you are a beginner or somebody who is just getting started with using SARMs, then this is going to be the stack for you. The average muscle gains for this stack are around 7 to 10 lbs over an 8-week period.

Week:LGD 4033 dose per day:MK 677 dose per day:

You buy both of the bulking sarms for this stack at one of these sources. The dosage guide assumes that you are using their products. If you shop elsewhere, you might end up with difficulties in accurately dosing your products.

Advanced SARMs stack for maximum bulking gains

Advanced Bulking Stack

If you are someone who wants more extreme results, then this stack will be better suited for you. I must warn you that this bulking stack was designed for people who have prior experience with SARMs. You will gain a minimum of 20lbs of muscle with this cycle.

WARNING: This stack is not meant to be taken by anyone who is worried about getting “too big”. Your friends and family will be asking you if you are taking steroids! Proceed with caution!

Week:LGD 4033 dose per day:MK 677 dose per day: RAD 140 dose per day: YK 11 dose per day:

It is extremely important when taking sarms for bulking that you only purchase from reputable sources. Oftentimes less reputable sources will put a single prohormone in each of the different products they sell in order to save costs. This becomes dangerous when you are stacking three to four products and they all contain the same dangerous prohormone. Because of this, we recommend shopping with one of our approved sarms vendors.

How to take the bulking stack


Make sure you have all of your ingredients ready before you start your sarms bulking cycle. You want to be sure that your supplies are adequate to last the entire duration. There is nothing worse than miscalculating how much of a single product you need only to run out early.

Splitting Doses

Splitting doses between morning and night is an easy way to ensure that blood concentrations for each compound remain stable. You want to avoid high peaks and encouraged stable levels throughout the day. You can easily achieve this by taking half of your dose in the morning and the remaining dose at night.

Do not worry too much about taking each SARM at a precise time. As long as it is close you’re good.

Support Supplements

Having a good lineup of support supplements is important when you are stacking sarms of any kind. You want to make sure that your body is running efficiently while you are on a cycle. For this reason, we recommend a few different supplements to include in your bulking stack:

  • Creatine, 10g a day
  • Fish oil, 3000mg a day
  • Protein powder if needed
  • Gatorade or Pedialyte to help with hydration.

Post Cycle Therapy (PCT)

After you have completed the sarms bulking stack, you will want to readjust to a natural lifestyle. Many other experts recommend a Post Cycle Therapy, which is a good idea if you are stacking multiple compounds at once.

If you are absolutely gung-ho about taking a PCT, then go ahead and do it. Tamoxifen or Clomid are both good options, as long as you keep the doses low. These drugs both have many side effects, and you don’t want to deal with that. 10 mg of tamoxifen should be plenty and don’t take more than 25 mg of Clomid during your PCT.

What is the best SARM for bulking?

Without a doubt, RAD 140 is the strongest sarm for those who want to get as big as possible in the least amount of time. Another good option is LGD 4033.

Is ostarine good for bulking?

Ostarine can be used for bullking cycles, but it is not the most optimal choice since it doesn’t provide as much appetite increase or androgenic effects as RAD 140, YK 11, or LGD 4033.

Which SARMs can I stack for bulking?

A classic stack for bulking is to combine either RAD 140 or LGD 4033 with MK 677. More advanced users can add in a third compound such as YK 11.


The sarms bulking stack is going to provide the best results when you take your training and diet seriously. If you follow this guide word for word, you will gain muscle mass. How much muscle you gain will depend on the quality of your source, your diet, and training routine. We have given recommendations for each, and we urge that you follow them.

  3. Hello, thank you for the information and everything.
    I wanted to askyou a question, can i stay from the beginning until end on the same dosage, mk677 25mg and lgd4033, rad140,yk11 10mg

  4. Hi Chris, is there any stack better for us over 40’s? Im 6ft and 204lbs – need to drop some fat and gain lean muscle. I bought some MK-2866 from to see what it looks like and try it out. Its blue capsules of 10mg apparently. I noticed they are not on your verified list partly due to no 3rd party testing. It shows a certificate on the MK2866 product photo but not sure how you tell if legit. Do you know if any of the verified suppliers have success distributing to the UK as I rather buy a known supply. Thanks

    • I’ll have to check them out again – they didn’t have COAs up when I did the review. Ostarine will be a great run for you and I’d highly recommend picking up some MK-677 to stack it with. MK-677 isn’t a SARM but it essentially acts as an oral version of HGH. It’s a great compound especially for people who are a little older.

  5. I have my gear from
    Is this one a verified site? Or should I throw that stuff away?

    Thanks for helping me out!

    • Reviews are mixed for them. Wouldn’t necessarily throw your gear away but make sure you are paying attention to your body’s reaction. If possible get bloodwork done mid cycle to check for signs of pro hormones or liver toxicity

  6. where can i buy these? Legit site?

  7. wich is better to get muscle rad or lgd 4033 post cycle mass

  8. Is LGD4033 and 2866 a good stack

  9. 1) Yes that’s correct. Since you’re on HRT you do not need to worry about shutdown.

    2) Great combo – I love cardarine. 20mg/20mg is a pretty common stack for GW and MK677.
