Andarine S4: Before and After

Andarine S4 is known as a SARM that packs quite a punch but doesn't have the worst side effects. Is this SARM really worth it, and what can you expect?

Andarine S4 (GTx-007) is known as a SARM that has been used to increase lean muscle mass and has been tested in the medical world to do so for people suffering from muscle wastage diseases.

SARMs or Selective Androgen Receptor Modulators have been theorized to replace more aggressive compounds in the medical world, such as Anabolic Steroids.

S4 has also been shown to be a great compound against osteoporosis and benign prostatic hypertrophy.

Of course, it wasn’t long before the fitness community would stack Andarine with their Creatine and Protein to build muscle mass, burn fat, and improve physical endurance.

But is it worth it? What kind of results can you expect, and what are the side effects of such a compound?

Key Takeaways

  • Andarine S4 is a SARM that can be used to decrease body fat, increase muscle tissue, and help with bone density
  • Most people report decent results with manageable side effects
  • It seems to be slightly better for increasing muscle mass than decreasing fat mass
  • While Andarine is not very suppressive, a post cycle therapy would maybe be necessary

What is Andarine S4?

Andarine S4 is known as a SARM that has been developed to help those who struggle to build muscle mass. This can include elderly people as well as those who suffer from illnesses and injuries and are now in the muscle rebuilding phase.

SARMs bind to the Androgen receptors in the body and cause a biological change that can result in more lean muscle mass. Overall, it seems like Andarine is rather good in a bulking cycle, and a lot of amateur bodybuilders have used it with great success.

Since it is not the strongest of SARMs, you do not need to be too concerned with side effects. All SARMs do have sides, and we will get into the sides of Andarine in a bit.

Before and After Andarine S4

Reddit Review

On 50 mg daily right now. 1 week in, vision is tinted yellow green, sorta strange, night sight is okay, takes time for eyes to adjust to changes in light. No other side effects, no hair loss. Planning on increasing to 75mg per day 4 weeks in till the end of the cycle.

1 week In I have gained 6 pounds. I was already musclular and lean and could see veins popping and now they are popping even more and in new places. Mentally feel great. Pumps are good. Been training for 10 years, just wanted a slight performance boost.

Sex drive is fine. Have enclo on hand, might add at 6.25mg per day starting in week 4 to end of cycle and as pct.

Also taking 10 mg cardarine per day. I don’t think it’s made a difference so far.

All purchased from Receptor chem, shipped to Canada

Pre cycle test levels were 730 ng/dl total and high shgb.

Have experience with one Rad-140 cycle two years ago. Rad caused me severe hairloss, took 1 year to recover with finasteride. Compared to S4, rad made me have an even higher elevated felling of happiness and aggressiveness, strength increase was greater and over felt stronger. Didn’t do rad again because of Hairloss. So far I prefer S4.

Happy so far

SARM Review

This bodybuilder had a decent physique to start off with, he probably reached a plateau, deciding to turn to SARMs for help.

What he did in eight weeks with the help of S4 and Stenabolic is respectable.

His upper and lower abs are quite impressive; it’s hard not to feel jealous while looking at them.

Arms, shoulders, pecs and delts all grew dramatically, and he now looks like a proper movie star.

He gained around five to six pounds of muscle mass and lost 6% of his total body fat.

It’s quite astonishing, but he claims to not have felt any side effects from Andarine, even at such a high dosage. Some people are just burn lucky and he is definitely one of them.

By the end of his cycle, he did feel a bit suppressed, so he opted for a mild four-week PCT with Nolvadex.

How to get Andarine S4?

If you are looking to use Andarine in your endeavor of building muscle mass, there are plenty of SARM vendors online to choose from. Our best experiences were with the likes of Sports Technology Labs and Amino Asylum.

S4 Summary

S4 Andarine

Andarine (developmental code names GTx-007S-4) is an investigational selective androgen receptor modulator (SARM) developed by GTX, Inc for the treatment of conditions such as muscle wasting, osteoporosis, and benign prostatic hypertrophy (BPH). [7]

Its anabolic activity has been viewed to be comparable to testosterone, but unlike anabolic steroids, Andarine does not suppress luteinizing hormone (LH) or follicle-stimulating hormone (FSH).

As a result, Andarine is able to increase muscle and bone mass without affecting the prostate and does not result in many of the negative side effects that come with the use of anabolics. 

Andarine has become popular as a cutting agent since it accomplishes fat loss by decreasing lipoprotein lipase (LPL) levels and decreasing water retention. Andarine will also prevent you from losing your hard-earned muscle mass and it may even help you to put on lean muscle mass.

Is Andarine S4 Legal?

All SARMs may only be purchased as “Research Chemicals” and “Not For Human Use”. This is because SARMs are still being tested to see if they create the perfect Anabolic environment without creating too many side effects.

After all, this is a medical compound first and foremost. If the side effects outweigh the benefits, it simply would not be worth it.

Andarine S4 Side Effects

  • Increase in cholesterol and blood pressure
  • Potential Testosterone suppression
  • Abuse can lead to hormonal disorders
  • Yellow vision

Conclusion: Is Andarine S4 worth it?

Andarine S4 is a valuable SARM in the view that it can help accelerate muscle growth without bringing too many sides. Yes, the Andarine S4 SARM does have sides, but unlike Anabolic steroids, these are easily managed, especially at low dosages.

When looking at the benefits of bone tissue, and muscle tissue, and the effects it has on the fat-burning process, it certainly is worth it to the right individual.

Does Andarine raise testosterone?

No, it would not raise Test levels in the body. It will give you a similar effect to testosterone, such as muscle gains and fat loss, but not exactly the same.

Is S4 good for weight loss?

Absolutely. Many bodybuilders use it in conjunction with other supplements and compounds to improve their cutting cycles.

Is S4 for bulking or cutting?

Both. Andarine S4 (and every other compound) was never created for this purpose, so, it depends on how you use it and what you use it with.

Is S4 stronger than Ostarine?

It would appear so, yes.
