Are you looking for Andarine S4 SARM? Look no further. We’ve put together a post explaining what Andarine S4 is and how it can benefit you.

SARMS or selective androgen receptor modulators are drugs that are designed to increase muscle mass without the side effects associated with anabolic steroids. To learn more about SARMS see our post: What are SARMS?

What is Andarine S4 SARM?

Andarine S4, also known as Andarine, Andarin, S-40503, or GTx-007, is a SARM that selectively binds to androgen receptors in skeletal muscle tissue. This compound greatly improves the body’s ability to grow muscle mass. This also results in severe strength improvements as well as aesthetic improvements to the body composition of subjects.

The current research shows that Andarine S4 does not convert into estrogen-like anabolic steroid compounds do. This means there are fewer side effects when using Andarine S4 compared to steroids. There are no side effects such as damage to the hypothalamic-pituitary-testicular axis. You do see those side effects in some anabolic steroids.

How Does Andarine S4 Work?

Andarine S4 was created by a Japenese company called Kaken Pharmaceutical and further developed by GTX inc. It’s an investigation SARM that was developed for the treatment of diseases such as BPH (benign prostatic hypertrophy), osteoporosis, and muscle wasting disease. It’s an orally active compound that is a partial agonist of the androgen receptor. That means that it binds to active androgen receptors and activates them to produce a muscle-building response.

Andarine was shown in studies to reduce prostate weight by 79.4% and increase muscle weight in lab rats. It shrinks the prostate gland by binding to dihydrotestosterone in the prostate gland. It doesn’t have the side effects of traditional antiandrogens that are used to treat conditions such as BPH.

Andarine S4 Dosage and Half-Life

Andarine is a lower potency SARM drug when compared to stronger SARMs such as RAD 140, which is currently considered to be the most potent SARM. It is still recommended to start with lower dosages to determine if you will experience side effects and to keep these side effects to a minimum.

A typical daily dosage of Andarine is about 25-30mg per day. Cycle lengths are typically 10-12 weeks. Sometimes it is recommended to take the compound 5 days on 2 days off during the cycle.

The half-life of Adnarine is about 4-6 hours. Due to this, it is generally recommended to dived the daily dosage into 3 separate doses. This is based on anecdotal evidence from bodybuilders experimenting with this drug. This is to help reduce the detrimental side effects that can be caused by this SARM. People have been reported to take up to 75mg per day but higher dosages mean a higher probability of side effects.

A typical concentration of Andarine may come in 50mg per ml.

What are the Benefits of Andarine S4?

There are many benefits of Andarine. Since it was developed for muscle-wasting disease it is very powerful at building muscle mass in skeletal tissue while ignoring growth in other muscles such as organs. Here are some of the reported benefits of Andarine:

  • Major increases in muscle mass and strength.
  • It assists the body in burning fat which can reduce body weight while not reducing muscle mass.
  • It increases the strength of your bones (which is being tested against osteoporosis).
  • Andarine can increase your sex drive and sexual stamina.
  • It doesn’t have many steroidal-like side effects.
  • It can be stacked with other SARMs to produce even greater results.
  • It’s fairly safe if used in the recommended dosage range.

What are the Side Effects of Andarine S4?

SARMs generally have fewer side effects than steroids due to the selective nature of the drugs. Two of the most prominent side effects reported with Andarine are suppression of testosterone and yellow or blurred vision. Testosterone suppression generally requires Post Cycle Therapy (PCT) to correct natural hormone production. The vision issues associated with SARMs are generally reported to subside when you stop taking the compound.

Another concern with oral compounds is liver toxicity. This is due to the fact that the compounds need to be processed by the liver to enter the bloodstream. This can put the liver under stress and raise damage indicators such as liver enzyme levels. It’s recommended to take a liver support supplement with oral compounds.

Andarine S4 PCT

Some users have shown very slight hormone suppression when using S4. A short, mini post cycle therapy regiment is required; the recovery time is only 2-3 weeks after completion of the cycle. The hormone suppression of Andarine is mild compared to RAD 140. Due to this, it may not be necessary to run common, more powerful, PCT drugs like Clomid or Nolvadex.

A PCT supplement with an aromatase inhibitor may be all that you need to help restart your natural hormone production. However, if you experience more severe hormone shut down after your cycle you may need to go with a more traditional PCT therapy. A common PCT for steroids is 50mg of Clomid for 2 weeks and then 25mg of Clomid for 2 more weeks. This may be helpful after Andarine usage.

Is Andarine S4 Safe?

SARMs are still in the research phase. That means that these drugs may not have been tested on very many people. Most of the feedback we have comes from anecdotal evidence from bodybuilders experimenting with Andarine. It has been used safely by thousands of bodybuilders but you should still use caution if you do decide to try this powerful drug.

With all drugs, you need to weigh the risk versus the reward of the compound. You will gain muscle in a short period of time but you want to watch out for the negative side effects that we mentioned above. You want to start out with a lower dosage of the compound. People taking higher doses have reported more severe side effects.

Most of the side effects of Andarine appear to be reversible or go away when you stop using the drug. However, you should use SARMs at your own risk and be aware that they can cause serious side effects.

Is Andarine S4 Legal?

It’s not approved for use by agencies like the Food and Drug Administrations (FDA) in the United States or World Anti-Doping Agency. Athletes have been banned from competition for using SARMs similar to Andarine as a performance-enhancing drug.

At this time Andarrine can be used as a research chemical in most countries. These research chemicals are marked “not for human consumption”. Research chemicals are designed to be used for clinical trials and medical research. This is a legal loophole that allows many users of Andarine to obtain the compound.

We’re not lawyers, but it appears that possessing Andarine is not technically legal but you are not allowed to consume it unless you are doing it in a clinical trial type of environment. Use these drugs at your own risk.

Some countries, like Australia, have classified SARMs in the same class as steroids which means that they are not legal.

Where to Buy Andarine S4

Andarine is quickly growing in popularity. Due to this many nefarious actors are trying to profit from its popularity by selling products that don’t contain Andarine or even selling oral steroids marketed as SARMS. This can be very dangerous to the user.

It’s critical that your vendor has a generous return policy and guarantees their products. You also want quick shipping and lab testing for every batch. This is why it’s extremely important to get your SARMs from a reputable and proven source like Proven Peptides.

Alternatives to Andarine S4

Do you want to build muscle and increase strength without the use of drugs? For some people, the side effects risk of drugs like Andarine S4 are too much. There are some supplements on the market that promise to boost testosterone and therefore increase the anabolic properties of your body. Of course, these supplements will not have the drastic results of steroids or SARMs but they can have a positive effect. Here are some testosterone boosting supplements that may help you reach your goals.

Andarine is a very powerful muscle building SARM. It doesn’t have many of the negative side effects of traditional steroids. However, that doesn’t mean that it has no side effects. The side effects depend on your response to the drug and the dosage that you use. For the most part, the side effects seem to go away after you stop the usage of the compound.

Andarine can cause minor hormone suppression so it is often recommended to use Post Cycle Therapy (PCT). A typical result might be gaining 10-12lbs of muscle mass over a cycle. Due to this many bodybuilders have been experimenting with Andarine and other SARMs.
