We dive deep into SARMs for cutting, bulking, and recomp and reveal the most effective stacks.
As with many compounds that have gained popularity among lifters and bodybuilders, few people know what SARMs actually are and how they work.
Most focus on the insane results they provide.
If you want to get the physique of your dreams, you must understand what SARMs are as well as how they work in our body.
In this review, we’ll talk about using SARMs for bulking and cutting fat, and everything in between.
By the end, you’ll understand what they are, how effective they are, and how they can help people like you reach your fitness and bodybuilding goals.
If you are wondering whether SARMs are illegal and how you can use them safely, we’ll have answers for you as well.
The 7 Best SARMs for Body Building
No two SARMs are created equal.
Which ones you take will depend on many factors, including the sensitivity of your body towards anabolic steroids, the dosage, the length of your cycle, and the results you want to see.
So, to know what the most effective ones for burning fat, bulking, or power are and how to best stack SARMs, you need to understand the differences between the various compounds and their effects on your body.
Knowing the differences will help you choose the right SARMs for you.
1. Ostarine (MK-2866)
Ostarine MK-2866 is one of the most widely researched SARMs.
There’s more information about Ostarine’s safety, efficacy, and dosage than many of the other compounds you’ll see on the market.
Ostarine is developed by a Memphis-based company called GTx Inc.
Researchers are studying the MK-2866 as a possible way to prevent muscle tissue loss and muscle wasting in patients with muscular dystrophy or various cancers.
Ostarine has been shown to burn fat, increase muscle growth and boost power.
It even has mild fat-burning effects during clinical reviews.
It also can lower HDL cholesterol and blood glucose levels for some people.
It is often used in the triple stack, which is best at fat burning, bulking, and everything in between.
Whether you’re using Ostarine MK 2866 on its own or as part of a cutting stack, it’s the best place to start as a beginner.
Ostarine is one of the more well-studied compounds, with several clinical trials showing its efficacy and safety in relatively low doses.
It can be used for cutting, bulking, and building lean muscle mass, as well as stacked with a similar molecule, like SR9009 or Cardarine.
Ostarine is often considered a cutting SARM for weight loss or fat loss, which means it’s perfect for a cutting cycle.
Many users looking for weight loss tend to use MK-2866 since it works hand in hand with the caloric deficit for fat loss.
It helps a person stay healthy and lose body fat even when they’re running on fewer calories.
The process of taking Ostarine helps maintain muscle mass during a cut, which is why it’s considered one of the leading SARMs for bulking, weight loss and cutting.
Researchers who use this for clinical reviews recommend a dosage between 3 mg to 5 mg per day.
Bodybuilders tend to take anything from between 10 to 30 mg per day, depending on their needs to build muscle mass and lose body fat.
Remember that the hormone suppression effect will be stronger the more you take, even with a compound as mild as MK-2866.
As with all other similar supplements, it does have a hormone-suppression effect which is why Post Cycle Therapy (PCT) is crucial.
So, it’s a good idea to keep your cycles to a maximum of 12 weeks, especially when using it stacked for building muscle instead of just during a cut.
2. Andarine (S-4)
Andarine S4 is another compound developed by pharmaceutical company GTx Inc.
As with Ostarine, its primary function is to lose fat, maintain bone density for people suffering from diseases like muscle wasting.
It can be used during a cut to retain a lot of muscle mass, but it shines if you want to bulk and in a stack.
S-4 is also a part of a stack for bulking and at the same time considered one of the most powerful SARMs for cutting body fat.
Despite being labeled as “mild” by some, S4 can produce extremely useful results, even at relatively low doses of 25 mg per day.
Most people will eventually build up to 50 mg per day, though high doses for weeks aren’t recommended due to Andarine’s effect on body hormone levels like testosterone and estrogen.
It’s also a good idea to avoid using S-4 for more than an 8 week cycle at a time and to make sure to do a PCT afterward.
Although it is mild, it does have some drawbacks, including having to take it numerous times a day due to its short half-life.
Some people report getting a yellow tinge to their vision, which isn’t permanent and stops a few days after.
If these drawbacks don’t put you off and you just want to be building muscle, Andarine is a great option that promises the best results.
Otherwise, you can always do a PCT after an 8 week cycle of using S-4.
3. Testolone (RAD140)
Testolone was developed by Radius Health, a pharmaceutical company located in Massachusetts.
It was developed as a drug to help deal with the muscle-wasting disease, as is the case with most of these compounds.
It’s generally considered one of the “strongest” SARMs available for building muscle and increasing energy, due to its extremely high binding affinity to androgen receptors.
Research conducted on RAD140 tends to maintain a dose of around 10 mg per day.
Most users will go no higher than 20 mg per day, due to its potent effects on testosterone production.
It’s mainly used to build muscles and also bulking up, though some users have had success using it for reducing body fat as well.
Unfortunately, due to its high binding affinity for androgen receptors, Testolone needs to be monitored carefully during use.
It should not be used for a cycle lasting longer than eight weeks.
Although it is one of the strongest SARMs, users have had experienced changes in their testosterone hormone levels.
We recommend that you take a PCT supplement after your Testolone cycle.
4. Ligandrol (LGD-4033)
Ligandrol is one of the most popular products currently available due to its lean muscle mass-building properties and relatively few side effects.
It’s considered the mid-point between milder like Ostarine and harsher SARMs for sale like Testolone RAD-140.
In general, one of its benefits are fewer side effects.
Ligandrol is typically used for body recomp.
It is also considered one of the most excellent SARMs for cutting as it produces results.
There is some water retention, but this quickly subsides during your cycle as you start seeing strength gains and improved lean mass.
It’s effective at a very low dose (as low as 5 mg per day).
While it does take a couple of weeks to kick in, users report their strength shooting up even during a recomp.
Due to its mild nature, LGD-4033 Ligandrol is typically used as part of some SARM stack options, especially when combined with non-SARM compounds like MK-2866 and GW-501516 Cardarine for fat burning effects and preserving lean muscle mass.
5. Ibutamoren (MK-677)
MK-677 isn’t a SARM, even though it’s commonly marketed as one.
It goes by the common name of Ibutamoren or Nutrobal, or by its compound designation of MK-677.
Ibutamoren stimulates the production of growth hormone and IGF-1 during cycle without affecting the testosterone levels and other hormones in the body.
We recommend using it for its muscle-building properties, making it suitable for bulking.
However, as it can also stop muscle tissue from wasting away, it can be used during a cut and as part of a stack.
6. Cardarine (GW-501516)
Cardarine GW 501516 was first developed as an anti-tumor compound that prevented the formation and growth of numerous cancer tumors.
However, it caught the attention of the body building community, and they decided to use it as one of the safer steroid alternatives.
Despite commonly being marketed as a SARM, Cardarine isn’t one.
Instead, it’s a PPAR agonist that modulates the activity of specific receptors.
It has been shown in studies to increase cardiovascular performance as well as stimulating weight loss.
This feature is why it’s commonly found in a lot of stack formulations.
YK-11 is a relatively new compound.
Due to the lack of scientific evidence, it’s nowhere near as popular as many of the others.
It’s starting to gain a lot of traction with people who want to put on a lot of mass quickly without resorting to a stack.
This is why it’s definitely one of the best SARMs for bulking.
If you wan to learn more about this powerful compound, read our YK11 SARM review.
If you want to get most out of a cycle, you should take more than one SARM at once. Below is a list of the most popular stacks depending on your goals.
Best SARMs Stack to Bulk Up
When you’re bulking, you want to search for the stack that has the highest anabolic ratio, which indicates how well it binds to androgen receptors.
In general, you want to search the following ones, which are widely considered the most effective stack for muscle growth.
- Ligandrol LGD-4033
- Andarine S-4
- Testolone RAD-140
Best SARMs for Weight Loss (Cutting)
When you’re cutting, you’re not interested in a stack that helps putting on new muscle. Instead, you want the stack to preserve the muscle you have while going on a heavy caloric deficit to lose fat. So, during this phase, you want SARMs with high anabolic ratio that have proven muscle-sparing properties.
A SARMs stack for cutting can include:
SARMs Stack for Building Strength
If you want to gain strength using SARMs stacks instead, you should take a look at both Ligandrol and RAD140. You’ll get substantial strength from both products due to their ability to increase bone density and pack on mass without the need for a stack that a lot of people rely on. Stick to a short cycle with this stack and check your mass and bone strength at the end of eight weeks to see if you’re happy with the way your muscle has been building. We consider this the best combination for strength and gaining muscles.
SARMs Triple Stack
If you’re one of the bodybuilders looking to take your game to the next level, you should consider the triple stack and enjoy its benefits. There are many SARMs stacks out there, but the triple stack is considered the best combination for EVERYTHING. The combination consists of 20 mg per day of Ostarine, 50 mg per day of Andarine, and 20 mg per day of Cardarine for eight weeks. During this time, you’ll be able to build up new muscle mass, reduce fat, and even improve cardiovascular health thanks to the synergistic effects of stacking these three. It’s one of the most effective stacks out there, and it’s well worth the try.
Stacking SARMs for Recomp
During a recomposition you’ll want to cut fat and add lean muscle, which is hard to achieve. Luckily, there are at least two SARMs that are particularly helpful for recomp. We recommend that you stack GW-501516 for cutting and S4 to increase your strength. You may also consider adding LGD-4033 to the stack to increase the strength gaining and cutting properties of the other two.
SARMs Stack for Fast Healing
A little known fact is that SARMs can also help healing tissue damage and joint pain, which are common injuries in bodybuilding. The number one choice for healing is MK-2866. To increase its healing properties, you can stack it with MK-677 and SR-9009.
SARMs for Women
Since SARMs aren’t as hormone suppressing to the body as traditional anabolic steroids, they’re suitable to be used by women for gaining muscle mass and strength as well.
The best SARMs for women include:
Post Cycle Therapy: PCT Supplements for SARMs
PCT is essential if you take any steroid that can affect testosterone levels and its production.
Most anabolic steroids will cause suppression of natural hormone production, and it’s a good idea to give your body time to recover and restore its natural balance.
But since SARMs are less harsh than anabolic steroids, is it necessary to do a SARMs PCT?
The answer will depend on what compound you’re using as well as how long you’re using it for.
Stronger ones, like Testolone RAD-140 or YK-11, can be hormone suppressive, especially when run for long periods or in a stack.
Any normal dose that’s run for longer than eight weeks should be finished off with some PCT supplement, preferably by using a compound like Clomid or Nolvadex.
The way to know if you need post-cycle therapy is to get your bloodwork done and see whether to use a PCT supplement.
The results will give you the hard numbers that you need to make a good decision.
If your hormones are on the low end of your typical spectrum, it’s a good idea to do an eight weeks PCT to get back on track.
What Are SARMs?
SARM stands for Selective Androgen Receptor Modulator [R]. This class of drugs is used medically to lose fat, treat obesity or muscle wasting diseases. While there is still a lot of research being done around the efficacy and safety for the body, early results are promising. If you’re wondering, are SARMs steroids? The answer is no.
How Do SARMs Work?
Androgen receptors are pieces of protein that sit on the membrane of your cells and allow the cells to respond to a specific compound; in this case, androgens like testosterone [R].
By stimulating these receptors, anabolic steroids make them more sensitive to high testosterone levels and other androgens, accelerating muscle and bone growth.
Since SARMs target lean muscle and bone tissue, you’ll see a lot of growth in these areas without a huge impact on the rest of your body and your fitness.
They speed up the growth of your muscles, increase your strength, and help get rid of fat.
They can also be combined with other molecules in a stack to enhance results and take advantage of their synergies.
Are SARMs Safe?
No compound in the world is 100% side effect free, and any marketing that you see to the contrary should be taken with a pinch of salt.
If you’re wondering whether SARMs are safe, in particular, the answer is maybe.
They are a relatively new class of compounds, and there have been very few long-term studies that have tested them for long-term safety.
They’re currently not illegal [R] because they haven’t been approved for human use by any agency, though they are up for approval at the FDA.
That said, they do have noticeably fewer side effects than steroids or other performance-enhancing drugs.
However, there is growing evidence that they may have the potential to increase the risk of heart attacks and strokes.
High dosages and large cycles can also lead to:
- Testosterone suppression
- Hair loss
Increased risk of cancer in high dosage (currently, this is only discovered in mice. But if you’re freaking out about aspartame causing cancer, you may as well freak out about them causing prostate cancer as well.)
These effects can be compounded if you’re working with a stack, so keep an eye out for side effects, especially when trying to find the SARMs stack for your needs.
Another important aspect to consider when looking to buy SARMs is that due to the unregulated nature of the supplement industry, many unscrupulous vendors will sell products that don’t even contain any active ingredients.
Make sure to read our guide before considering whether or not to start a cycle and use a trusted vendor such as Science Bio.
A recent article in the Journal of the American Medical Association found that only half of the products advertised as they contained active SARM compounds.
And what’s worse, over 60% contained ingredients that differed significantly to what was printed on the label.
10% of products didn’t even contain a trace of any active ingredient of any kind.
So, in the interests of safety, make sure to order from only a trusted vendor and make sure that the product is genuine and third-party lab-verified before you start using it.
Where to Buy SARMs Online
Finding the best place to buy SARMs can be extremely difficult, considering how unregulated the market for them currently is and how many questionable vendors have SARMs for sale.
It’s a good idea to stick to reputable vendors such as Science.bio, which has a reputation for selling high-quality products that contain what they say on the label.
Also, make sure to check real Science Bio reviews to get an idea of the quality of the product you’re buying and how they affect your fitness and health.
At Science Bio you get the highest quality SARMs you can get your hands on.
How to Take SARMs?
Your cycle will depend mainly on the type of SARM you’re taking.
Some of the stronger ones, especially when you are taking it in high dosage, can result in lower testosterone levels or suppression.
So, it’s smart to keep to relatively short cycles when using high doses or when you stack SARMs.
Also, consider combining them with something like SR9009 or Cardarine to come up with a stack of your own and make it effective and stronger.
Most SARMs cycles will last between eight to twelve weeks, with PCT performed as required.
Most daily doses of stacks are kept low, around 20 to 50 mg per day, as the higher dosage isn’t necessary to achieve the best results.
The main thing you need to factor in is the half-life of the SARM or stack you’re taking, as this will determine how many times per day you need to dose.
SARMs with shorter half-lives need to be ingested at least twice daily, while others only need a single dose daily.
Are SARMs Legal to Take?
The short answer is yes. SARMs aren’t FDA-approved and can’t be sold as supplements for human consumption. But it’s completely legal to take SARMs. And they are also legally sold as “research chemicals” rather than “supplements”.
SARMs are the best alternative to steroids if you’re looking to gain muscle fast.
These research chemicals are often less harmful to the body with almost zero side effects while offering many of the same benefits.
Since they are still in clinical trials, most aren’t illegal and are instead considered grey-market drugs.
As with all other supplements, exercise caution when choosing to get SARMs and make sure to use a reputable vendor who you can trust to get the most profound effects possible.
Never be scared to ask a question and be aware that a lot of vendors want you to submit an order without caring about the effects the SARMs will have on your body.
