S-4 (Andarine) Descriptions:

S4 is a form of SARM that attaches to the androgen receptor (AR) the same with regular androgens, the only variation is that S4 generates selective anabolic activity. S4 is a SARM with utmost androgenic effects as it around 33% of the strength of testosterone when attaching to AR.

Compared to anabolic steroids and prohormones, Andarine does not have androgenic activity in non-skeletal muscle tissues

S4 is a SARM with maximum potential with a disintegration process of just 4 hours. It can decrease the size of the prostate if taken as recommended. It is administered orally.

It’s shown to be beneficial for muscle degeneration, osteoporosis and benign prostatic hypertrophy (with bicalutamide – a non-steroidal androgen antagonist) treatment. Aside from preserving lean body mass, S4 can also help improve it.

Aside from its muscle building advantages, S4 won’t cause liver damage, can prevent gynecomastia (enlarged breasts in men) and can help boost your overall health.


Andarine Review:

Andarine is a selective androgen receptor modulator (SARM) prized for its ability to boost lean muscle mass and increase bone density. Here’s our Andarine review.


Uses of Andarine:


For Cutting (best use of S4)


Andarine’s properties are very alike with steroids Anavar and Winstrol, the only difference is that S4 can better provide lean muscle gains. S4 displays the same binding resemblance to AR, hence presenting similar fat burning effects. S4 can also minimize LPL (lipoprotein lipase) – an enzyme that causes lipid accumulation.

Furthermore, Andarine also decreases fat while maintaining and even boosting muscle mass in a hypocaloric environment. It also improves vascularity for that “aesthetic” chiseled look with minimal to no water retention. Unlike steroids, it won’t affect your joints but reinforce muscle mass and power instead. You can also say goodbye to painful pumps.

Recommended Dosage: 50 mg for 6-8 weeks.

Take 2 days off when taking S4 (repeat the cycle after the 2 day break) to avoid vision side effects.

For Recomping

Use S4 with a more anabolic SARM such as Ostarine for better recomp results as you’re aiming to gain muscle while losing fat. Recommended intake is 50-75 mg for 4 to 8 weeks.


For Lean Muscle and Strength Gains (sans bloating)

The strength gains that Andarine produces are quick, lasting, maintained and very clean. S4 makes you feel good all over.

Suggested dosage is 50mg.


How Does Andarine Work?

Andarine works in a similar way to most SARMs – it selectively targets certain androgen receptors in your body, maximizing the benefits of steroid-like compounds while minimizing the downsides.

Andarine also has the unique ability to dry out your muscles and the skin surrounding those muscles – which can help increase your tone, reduce fat, and benefit your cut. This is the same reason why Andarine is prized for weight loss.

At the same time, Andarine is also used to build and repair muscle.

Many people compare the effects of Andarine to the popular steroid Winstrol.


Benefits of Andarine:

— Cutting (this is the most popular use for Andarine)

— Non-methylated

— Provides a hard and dry look by tightening your skin and drying out muscle

— Stimulates fat loss

— Minimizes estrogen conversion

— Full PCT is not recommended by some users (but you should probably still do it just in case)

— Inexpensive


How to Use Andarine:

Andarine is typically used at doses of 50mg. Doses beyond that amount can lead to some unwanted side effects.

One reviewer at Evolutionary.org claimed to gradually increase Andarine throughout his cycle before doing post-cycle therapy:

— Week 1: 50mg

— Week 2: 60mg

— Week 3: 70mg

— Week 4: 100mg

— Week 5: 125mg

By week 5, the reviewer noted that he had permanently yellow eyes and no night vision – similar to what happens when you take certain steroids for a long period of time. Andarine’s yellow eyes side effect appears to be particularly common when taking prolonged doses over 50mg. The reviewer concluded that “sides [side effects] far outweigh the benefits at this dose”

Nevertheless, the reviewer also reported massive increases in strength and endurance and increased lean muscle mass. By week 5, he claims he felt like he was on Winstrol or Anavar.

Ultimately, that reviewer went on to recommend that you use Andarine for 5 days on, 2 days off at doses of 50mg to negate any side effects.

He also recommended post cycle therapy.

If you’re taking Andarine to reduce symptoms of gynecomastia, then the reviewer recommended a cycle of 6 days on, 1 day off at doses of 20mg.


Is Andarine Legal?

Andarine, like all SARMs, is banned by the World Anti-Doping Agency according to their 2008 decision. So if you’re participating in any type of athletic competition under the jurisdiction of that agency, then you should probably not take Andarine.

If, however, you’re taking Andarine for personal use, then the supplement is in a bit of a grey area: at this point, nobody is really sure whether or not SARMs are legal or illegal. The FDA’s 2014 decision to enact the Designer Anabolic Steroid Control Act (DASCA) made it effectively illegal to sell anabolic steroids, making SARMs the next-best legal alternative.

However, even the most optimist bodybuilding supplement manufacturers don’t believe that SARMs like Andarine will stay legal for very long.

Part of the problem lies in the supplement’s powerful medical benefits. As mentioned above, the supplement was initially created in order to reduce enlarged prostate problems, treat osteoporosis, and reduce symptoms of muscle wasting disease. As a result, many people classify Andarine as an actively researched medical drug – which should thus disqualify it as a nutritional supplement and put it under the jurisdiction of the FDA.

Nevertheless, Andarine hasn’t faced the same scrutiny as other SARMs like Ostarine and it has not been the subject of any lawsuits.


How to Buy Andarine?

S4 (Andarine) is available from a small number of retailers online. Companies like SARMS1 sell S4 (Andarine) at doses of 50mgs/mL @ 30mL for $79.99.

Even at the sales page for Andarine on SARMS1.com, the retailer admits that the product is “intended as a research chemical only” and “bodily introduction of any kind into humans or animals is strictly forbidden by law.”
