What is Andarine S4?

Developed by GTX Inc, Andarine S4 is a SARM whose functionality is similar to that of steroids but instead works selectively on the Androgenic Receptors. This way it helps you gain a lean muscle weight minus the worrisome side effects. In this article we shall talk about what Andarine does, its dosage, benefits, side effects, and its legality in research, sports, and as a food supplement.

Everyone wants to have a healthy body that looks fit. Bodybuilders and athletes work day in and day out in the gym to get that perfect shape. In addition to that, proper sleep and a proper diet is really important. But at some point, they start feeling exhausted or maybe they simply want to practice more.

For enhancing their performances in the gym or practice, previously people started using steroids but they come with too many negative side effects. Meanwhile, SARMs started gaining its popularity. This drug lets you have THE energy for longer hours and at the same time, taking them in a cycle helps you add lean muscle mass and burn the fat from your body making you look and feel strong.

Plus, they do not have any harmful side effects like those in steroids, which is also the main reason for its quick fame among the bodybuilders and athletes

How does Andarine S4 work?

Andarine S4, also known as Acetamidoxolutamide or Androxolutamide or GTx-007 was created by a Japanese company Kaken Pharmaceuticals and later developed by GTX Inci. The main compound in the drug is antiandrogen bicalutamide. Andarine was introduced for curing muscle wasting, breast cancer, prostate cancer, benign prostatic hypertrophy and degenerative disorders like osteoporosis. Andarine S – 4 has shown to promote weight reduction of the prostate gland in people suffering from prostate cancer. It also greatly helps in increasing muscle mass. Plus, S4  helps to oxidize the fat in the body. This property was what made bodybuilders and athletes start using them as a safer alternative to Anabolic steroids. This is good for both cutting and bulking.

Andarine is much lesser potent than any other SARMs and it has a half-life of approximately 3 – 6 hours. It does not aromatize and thus prevents the excess release of estrogen and does not cause negative effects like high blood pressure or problems with the cardiovascular system. Andarine promotes the healing process in the case of fractured bones and cures the pain associated with brittle bones.

Dosage: How to use Andarine S-4

As mentioned earlier, Andarine S – 4 is a low potent drug compared to other SARMs, RAD 140 Testolone being the most potent one. So people often opt for higher dosages. We recommend lower doses so that the chances of having any unwanted effects gets minimal.

Dividing it into 3 separate doses that totally equal 25-30 mg per day is the most appropriate dosage is what our team found. You may need to use it only 5 days a week with 2 days gap between and this cycle goes on for 10-12 weeks. This dosage ensures you don’t get detrimental side effects like messing up with your eye vision. People taking a dose of 50 –75 mg/day will experience some unwanted effects like blurry vision and increased stress. That is why it is advised to take the drug only in doses in the lower levels.

Andarine as a product for bulking and cutting

  • Cutting

Andarine helps reduce the High Density Lipoproteins​ (HDL) and has the ability to repair bone fracture, promote bones and muscle development thereby preventing muscle loss. It also uses the fat in your body and helps burning extra fat, aiding in recupering. Having protein-rich food alongside the SARM dosage is really important since only then the drug works in its complete efficiency.

  • Bulking

When you start getting muscular, you want to make sure that your body does not look like it is just swollen. Removing excess water from your body is important here. Andarine does not aromatize, hence do not cause water retention and also burns down the fat in your body. These properties make your body look sharp, shredded and strong.

Stacking Andarine S-4 with other SARMs for best results

SARMs work best when you take them in stacks. Taking them in stacks helps you with the benefit of each SARM used and gives you the best results.

Bulking Stack

Ostarine MK 2866 and Andarine S4 stacked together and sometimes along with a low dose of Candarine GW 501516 is the one of the best bulking Stack out there. Each of the three are known to have great strength and are beneficial for both bulking and cutting. So this stack combination can also be taken for cutting. 20 m per day of Ostarine and Candarine and 25 – 30 mg per day of Andarineis the most appropriate dosage for desired results.

Cutting stack

Andarine and Testolone RAD 140 make a great cutting stack. Testolone is best known for its potential to give you incredible strength while Andarine aids in cutting down the unnecessary fat from your body. Both together work excellently in promoting the growth of lean muscle mass. Taking 10 mg per day of RAD 140 and 25 mg per day of Andarine S 4 will do the desired job.

Both the bulking and cutting stacks are to be taken for a 12 weeks’ duration.

How safe is Andarine S4?

By the end of your first cycle, you gain about 10 – 12 lbs and you have already awarded yourself a beautiful body that looks muscular, strong and totally just the way you wanted to. But is also this period that the little side effects start kicking in, like lower levels of testosterone, increased fatigue and weakness and you start feeling exhausted easily plus you might notice frequent headaches and nausea.

People taking this drug in higher doses as in ranging between 40 – 75 mg per day may observe some worrisome negative side effects like alterations in vision – some may experience blurry vision while some may find it difficult to distinguish between two different colors. This might happen because overdosing on Andarine leads to the product interfering the with rods and cones components of the eye.

Overdosing on Andarine also makes the person intaking it sufferS from depression and anxiety. So it is very important you take only the recommended dose, that is, a lower one – definitely not exceeding 30 – 35 mg per day.

When taking in no matter a lower or higher dosage, all of the side effects are reversible and do not cause any permanent damage and does not damage any of your organs. Andarine interacts with the negative feedback loop of the Hypothalamic Pituitary Gonadal Axis thereby may cause imbalance and decrease in Testosterone levels. Once you start your Post Cycle Therapy, each possible side effects diminish.

Post Cycle Therapy

Post Cycle Therapy, abbreviated as PCT is the period where you take a type of medicinal drug to help free your body from any side effects from the previous usage of the SARMs cycle.

In case of SARMs, you do not need potent PCTs like Clomid or Nolvadex. You may go for a PCT that is mild added with a Hcgenerate ES or maybe a Selectively Estrogen Receptor Modulator (SERM).Taking any of these would do the necessary job of removing the side effects and making you feel good once again. Our team’s personal favorite is the Red PCT which is made up of only natural ingredients making it easy for your body after a 12 weeks’ SARMs cycle. The ingredients present in the PCT include Grape Seed Extract, Agaricus, Luteolin, Bisporus, DIM, Resvaratrol, Apigenin and Acacetin. All seven of these are natural extracts and are pure natural aromatase inhibitors. They are absolutely not hard on your body like strong PCTs – Clomid or Nolvadex.

This cycle continues for a time period of 4 weeks. By the end of completion of this cycle, you recognize the fit perfect body you achieved while on your SARMs cycle plus the renewed energy and a pleasant mood devoid of any side effects achieved with the help of your 4 weeks’ Post Cycle Therapy. Your hard work has paid off and it is now time you allow your body to have a rest from all the cycles. You are advised to take a 3-4 weeks break and only then you can begin your next cycle.

Testimonials by real users

“I would go to the gym and exercise 5 times a week. Often during those sessions I got tired quicker than the others plus I wanted my body to be in an even better shape. I searched online one day and I came across SARMs in a particular article. I read all about them and bought my first bottle of Andarine from Umbrella Labs. I used it as advised and now I’m in my 2nd cycle. I no more get tired and workout for longer hours. My body looks stronger and just how I dreamt it to be.”

Jeffrey Roberts

“No matter how much I worked out, I never could achieve the muscular physique I desired. This really frustrated me and I was almost about to give up on working out anymore when my brother advised me to use Andarine and told me how so many people are using SARMs. He bought me a bottle and it worked like a miracle to me. I now flaunt my muscles and don’t feel sad anymore. This is the best thing that happened to me. I love how it has no side effects besides some crazy headache sometimes.”

Also, these do not aromatize, so they do not cause Estrogen imbalance keeping your body safe from any hazardous damage. Steroids are known to cause damage to your liver and kidneys and hormonal balance which are irreversible. Hence, SARMs are much safer than steroids.

Andarine is the least potent SARM available so people usually tend to take to these drugs in higher doses but you should also note that higher doses increases the possibility of side effects so taking them in just 25-30 mg/day 5 times a week for 12 weeks will do the desired work with almost no side effects
