Andarine Review (2023): 4 BIG Benefits From S4 SARM

It’s only natural for men to desire the best for their bodies.

Consequently, a quest has always existed to discover the best weight loss or bodybuilding supplement.

Men are frequently searching for the top weight stack to add strength, cut fat, as well as build lean and dense muscle mass.

Selective Androgen Receptor Modulators (or SARMs, for short) are performance-enhancing agents that stimulate anabolism.

Anabolism contributes to increased muscle mass and strength, as well as improves recovery time between workouts.1

Bodybuilders prefer supplements like Andarine (S4) during the Cutting Phase to achieve immediate results.

Andarine (S4) is easily one of the most dynamic and powerful anabolics for ditching unwanted fat.

The weight loss supplement is available for medical/therapeutic purposes, specifically for combating muscle atrophy and osteoporosis.

Learn more about Andarine (S4) in our complete review.

IMPORTANT: The below supplements are NOT intended for those under the age of 18.  If you are under the age of 18, do NOT consider taking them under any circumstances whatsoever.

Also, if you’re planning on joining the military, cease using this (and really any) supplement at least a couple months before going to MEPS. 

They can cause a false positive on a drug test, and will affect your chances of joining!

Andarine (S4) is a selective androgen receptor modular (SARM) designed to combat muscle and bone-wasting diseases.

Furthermore, there is evidence to support SARMs like Andarine against an enlarged prostate.2

Meanwhile, bodybuilders have started to tap into the potential of Andarine (S4) for weight loss.

The early results have been impressive as Andarine (S4) has transformed into one of the more powerful anabolics for burning fat.

Moreover, Andarine (S4) offers promising results for producing lean muscle mass and improving overall strength.

The benefits of Andarine (S4) are noteworthy:

  • Increases Lean Muscle
  • Improves Strength & Power
  • Fat Cutting & Weight Loss
  • Joint Healing Properties
  • Improves Recovery Time

The science behind SARMs is relatively new as the performance-enhancing agents were discovered in the late-1990s.

Nonetheless, the substance has gained notoriety among bodybuilders and those seeking to lose weight.3

SARMs are not anabolic steroids but, rather, serve as synthetic ligands that bind to androgen receptors (ARs).4

Therefore, SARMs may stimulate anabolism which is necessary to improve muscle mass and strength.5

Andarine (S4) interjects 50mg of the SARM for daily supplementation.

Notwithstanding, it’s important to note that Andarine has not yet been approved by the U.S. Food and Drug Administration (FDA).

Unfortunately, selective androgen receptor modulators (SARMs) are among many other alternative health products that require more government oversight to reach a firm conclusion on its benefits.

Be that as it may, there is growing research that supports the use of Andarine for improved athletic performance and body composition.

More Detailed Andarine (S4) Benefits

The potential of Andarine (S4) is enticing.

First, the selective androgen receptor modulator (SARM) speeds up the fat-burning process thanks to how it targets anabolism in the body.

Secondly, Andarine attaches to the proteins of the body and binds them together for stimulating the lean muscle.

Third, the SARM instructs the bones to increase density and strength – properties that are critical to strength training and building muscle mass.

Fourth, the bodybuilding supplement improves recovery time between workouts so that you can hit the gym sooner.

If Andarine (S4) sounds like a steroid it’s because SARMs operate like steroids yet do not produce the same nasty side effects.


SARMs selectively bind to androgen receptors (like muscle tissue and bones) compared to steroids which bind to all androgen receptors.

For this reason, Andarine (S4) is very similar to other SARMs like Ostarine, RAD-140, and LGD 4033.

Nevertheless, many consider Andarine (S4) the most powerful and effective SARM on the market.

Just take this Youtuber, who goes into pretty significant detail about the benefits of using this SARM: 

1. Fat Burning & Weight Loss Supplement

In general, most people new to weight stacks need to begin by losing weight before they can gain lean muscle.

Thankfully, Andarine (S4) does both with really impressive, almost immediate results.

Thus, users report shedding unwanted fat even on a slight calorie surplus.

It’s not uncommon based on reviews (more information, below) for individuals to lose 4-5% of their body fat.

Still, the individual results you achieve are dependent on several other factors including diet, workout frequency and intensity, as well as weight stack (get advice, below).

2. Improves Muscle Mass & Strength

Andarine (S4) is extremely popular for building lean muscle and improving overall strength.

Andarine is widely considered among bodybuilders as one of the most powerful and effective SARMs available in a weight stack.

Consequently, Andarine (S4) can help you gain 5 lbs of muscle even if it’s not the most prominent SARM for gaining lean muscle.

Moreover, Andarine (S4) also improves overall strength and fitness.

3. Improves Recovery Time

The importance of recovery is undervalued in the world of weightlifting and bodybuilding.

Thus, you need to build a weight stack that also allows your body to recover between workouts.

Fortunately, Andarine (S4) has a terrific reputation for improving recovery time so that you can return to the gym quicker

The ability to exercise more frequently and train harder is vital when someone seeks to lose weight and gain lean muscle faster.

4. Stronger Body Composition

Men hit the gym to lose weight and build lean muscle for more defined body composition.

Unfortunately, it’s not always easy to get the “look” you desire without the assistance of a weight stack.

Thus, Andarine (S4) keeps you looking sharp and cut since it targets body fat as well as muscle mass.

For this reason, those that lack muscle mass but have a lot of fat can notice the greatest improvements with Andarine (S4).

Andarine (S4) Dosage and Cycle Instructions

The manufacturers of Andarine (S4) suggest a daily dose of 50mg.

It’s noted that this dosage appears to demonstrate the best results for burning fat and building muscle mass.

More importantly, the 50mg dosage does not appear to produce any serious side effects (more information, below).

It’s important to remember to split the daily consumption between two separate doses of (25mg).

It’s recommended that you take half of the dose in the morning and the other half in the evening.


Andarine (S4) features a half-life of approximately 6-8 hours.

The producers of Andarine (S4) do not recommend using the SARM in a cycle longer than 8-12 weeks.

The good news is that SARM does not require Post Cycle Therapy (PCT) with the correct dosage and cycle length.

In general, a PCT is necessary to assist the body to recover to a natural state following the weight stack cycle.

Andarine (S4) is available in the following flavors: Sour Apple, Strawberry Lemonade, Elderberry, and Unflavored.

Lastly, Andarine will show up on a drug test, so keep that in mind if you play a collegiate sport or are joining the military.6

What the Research Says About Andarine (S4)

Andarine attaches to proteins in the body known as androgen receptors (ARs).

Selective Androgen Receptor Modulators (SARMs) act as performance-enhancing agents that direct muscles and bones to grow.

However, unlike steroids (which operate in a similar manner), Andarine does not bind to all androgen receptors and therefore avoids the nasty side effects.

The manufacturers of Andarine (S4) have the SARM undergo third-party testing, despite lacking FDA oversight.

Meanwhile, Andarine is gaining clinical support, especially when treating issues related to the prostate.7

All in all, there is research that indicates Andarine produces significant increases in muscle tissue and bone density.

Regardless, research will remain limited until the FDA relaxes its stance on Andarine and other SARMs.

Andarine (S4) Reviews

There is plenty of customer support for Andarine (S4) despite limited clinical research.

The product currently features a stellar 5-star rating on various forums:

andarine s4 before and after results

Additionally, Steve Hildreth states that he wishes he would have tried the muscle mass supplement sooner and labels it as “amazing”.

Finally, Jon C highlights the SARM for “increased strength, better physical appearance, and minimal side effects”.

Andarine (S4) Side Effects

The manufacturer of Andarine (S4) claims that the SARM does not feature any serious side effects.

They warrant this reassurance with valid third-party testing that verifies the potency and purity of the substance in each bottle.

Nonetheless, clinical research still remains limited regarding Andarine and other SARMs thanks to FDA rejection.

There is some concern from outside sources that Andarine may impair vision or suppress testosterone levels.

While true that Andarine does suppress the natural production of testosterone these levels are known to return back to normal within a few weeks of completing the cycle.

It’s why users should take note of the recommended cycle stage for Andarine (S4) which is a maximum of 8-12 weeks.

Secondly, there are a few vision concerns associated with Andarine yet the legitimacy remains questionable.

There is no direct correlation between the substance and any long-lasting or permanent vision problem.

Regardless, individuals should consider speaking with a physician before starting any new type of supplementation.

It’s especially important if you already take other prescribed medications or have serious health concerns.

Andarine is not approved by the FDA which makes it ripe for scammers to take advantage of on the black market.

Thus, we suggest considering purchasing only through a reliable manufacturer like GTX Pharmaceuticals.

Andarine (S4) With Other SARMS

Andarine (S4) is comparable to other SARMs like RAD 140, Ostarine, and LGD 4033.

The 4 selective androgen receptor modulators all perform in a similar matter with the primary distinction being the strength and amount of suppression.

Therefore, Andarine (S4) is widely considered more powerful than Ostarine yet not as strong as LGD 4033.

Nonetheless, most consider Andarine one of the most powerful and effective SARMs available for purchase.

Andarine is a versatile SARM that not only helps you burn fat but build lean muscle.

For this reason, consuming multiple SARMs at the same time in a cycle (otherwise known as “stacking”) may help you reach your fitness goals faster.

Let’s review some of the popular options for stacking Andarine with other SARMs:

Stacking Andarine (S4) and RAD 140

andarine s4 and testolone rad 140 is a great sarms stack

Andarine (S4) stacks well with RAD 140.

RAD 140 Testolone is another potent and powerful SARM.

The SARM is especially popular with athletes and bodybuilders that need an efficient supplement for maintaining muscle mass and energy.

RAD 140 addresses low testosterone which is something Andarine fails to accomplish.

As a result, the two pair together nicely to create a weight stack for gaining lean muscle.

You can pick up this stack at Sports Technology Labs, click here to learn more.

Stacking Andarine (S4) and 1-Andro

1-Andro is another top option for stacking with the powerful SARM.

The prohormone benefits protein synthesis, athletic performance, muscle growth, strength, and recovery.

Consequently, 1-Andro can help you bulk up with lean muscle and improved strength.

It’s recommended to continue the suggested dosage of 50mg of Andarine (S4) followed by 100-150mg of 1-Andro.

You can find both of these SARMs through Sports Technology Labs website, here’s a link:

Stacking Andarine (S4), MK-677, & LGD4033

Individuals may stack Andarine with MK-677 as an alternative to RAD 140.

It’s important to note that MK-677 supports muscle growth while its close cousin – LGD4033 – is designed for fat loss.

Regardless, MK-677 and LGD4033 are reliable and versatile supplements that complement Andarine (S4).

There is no need to consider Post Cycle Therapy (PCT) with SARMs like MK-677 and LGD4033 as long as use discontinues after 12 weeks.

Where To Buy Andarine (S4)

Andarine (S4) is available through the Sports Technology Labs official website here.

The manufacturer provides a completely secure checkout process with free shipping on orders over $100.

Furthermore, GTX Pharmaceuticals offers a 60-day money-back guarantee on all orders.

The SARM is sold in a 30mL/1 fl. oz container that features a dropper designed for individual doses at 25mg.

More importantly, you should consider stacking Andarine (S4) with other SARMs to get the best results.


What is there not to like about Andarine (S4)?

The selective androgen receptor modulator (SARM) is a much safer and more effective alternative to traditional steroids.

The SARM binds to androgen receptors critical to strengthening muscle tissue and bone density.

As a result, you will not only burn unwanted fat but gain healthy muscle mass.

Additionally, users of the SARM notice improvements in recovery time with a more defined body that attracts the opposite sex.

Unfortunately, SARMs like Andarine lack federal approval from the FDA which is too bad considering all the recent traction weight stack supplements like this are earning from satisfied customers.

Andarine (S4) is most effective when you consider combining with other SARMs for the ideal weight stack.

Ultimately, Andarine (S4) is one of the most powerful and versatile SARMs on the market.
