Andarine S4 – The Unbeatable SARM For Muscle Gains

Andarine, also known as S4, is a SARM (selective androgen receptor modulator) developed by GTX Inc for the treatment of muscle wasting ailments such as ALS and in AIDs patients.

Given its immense reputation, it was time we did a thorough review of Andarine S4 SARM. Since I was on an Andarine cycle earlier this year, I thought why not take this opportunity to tell you, our dear readers about what the hoopla is all about. I found that it is not hoopla but something real and so good that I cannot but recommend it.

How Does Andarine Work

SARMs, which are the most recent class of non-steroidal anabolic drugs on the market bind to androgen receptors in the cells. This allows your muscle and bone cells to absorb more testosterone from the bloodstream.

Androgen receptors have a very important role when it comes to building muscle mass. Since SARM drugs attach to receptors just like steroids, the effect from SARM drugs is similar but with no negative health effects.

S4, which was originally going to be a medication for prostatic hyperplasia has ended up being something far more. It promotes muscle growth at a tremendous pace, as well as increasing lipolysis. Naturally, it is a magnet for those interested in bodybuilding.

In brief, S4 is a fast-acting SARM with minimal known side effects.

What Benefits Does S4 Bring You

I read the studies about Andarine S4 SARM and my own experience also told me a lot. What this drug can do is a truly fascinating read.

Hypertrophy of muscle and increased bone density

Andarine S4 brings about a gain of several pounds of muscle after a few weeks of use. Clinical trials on animals have shown that S4 is very capable of developing lean muscle in a short period.

For bodybuilders, this means that it is possible to use S4 for developing a chiseled and rock hard physique without a lot of sweat.

With age, the density of bones begins to give way. This leads to fractures and osteoarthritis. The use of S4 is surefire prevention of this complication. Thus you are assured of old age with no fear of debilitating hip fracture and joint replacement.

Lack of overdosing

It is very easy to use S4. Have it just twice or at most thrice a day. With such a simple schedule, there is no fear of an overdose and a possible visit to the ER.

Lack of PCT

A huge drawback of steroids, apart from the illnesses they cause, is that the testes shrink in size. Since the body receives exogenous testosterone, the testicles see no reason to produce the hormone naturally. Due to this reason, the natural production ceases.

But this is a problem after one comes off a steroid cycle after a few weeks. The testes have to be coaxed into its natural cycle of hormone production using Clomid. A post cycle therapy can last for many months and is an added headache.

Improved sense of well being

Greater fitness which you receive from Andarine S4 SARM also brings you a greater feeling of well being. Since you are stronger and have more endurance, you feel better and have a lot more stamina to do all those things outside the gym that you always wanted but never had the vitality for.

Very low toxicity

Andarine S4 SARM has nearly zero toxicity. There is no heavy-duty work that has to be done by your body to metabolize it, and the byproducts of its action are excreted out through urine and sweat.

Possible Side Effects

You need not worry about gynecomastia or a lot of fluid retention. Andarine S4 SARM produces none of these side effects of anabolic steroids.

The only possible side effect is minor. In some, it has been reported that Andarine S4 binds to the cells of the retina, causing vision problems.

But the way out of this is really easy. Just come of S4, and the problem will disappear soon. The most well-known side effect is a yellowish tinge to your eyesight. This would cause problems with seeing colors like green and orange, which contain yellow as a primary shade.

As with all anabolic substances, the longer you use it, the less effective, it will be. The body becomes used to it and adjusts to a new normal or what is known as homeostasis. When you develop a tolerance, you either have to up your dosage or use another SARM for a while.


Among every SARM on the market, Andarine S4 has the shortest half-life of only 4 hours. This means if you take 10 mg at 8 AM, there is no more than 5 mg at 12 PM and 2.5 mg at 4 PM in your blood.

That is why it is best if the dosage is split into twice daily once in the morning and again in the evening. The usual daily dose begins at 25 mg and can go all the way up to 50 mg.

Andarine S4 SARM can also be consumed for longer cycles. It is rarely effective below cycles that are less than six weeks long, and it can go on as long as 16 to 18 weeks or almost five months.

Due to very little toxicity, this does not matter, and you can come of Andarine S4 for two months and go back upon it.

Based on anecdotal evidence, it is best if you do not consume it daily but only six days of the week.

Bodybuilders who are interested in often bulking stack Andarine S4 SARM with Ostarine or Cardarine. Some even add steroids like Nandrolone or Trenbolone. But I am no fan of steroids so cannot comment much about that aspect.

Personal Experience

At the height of an even six feet, I used to be 220 pounds and looked about 20 pounds too heavy. My abdomen seemed flabby, and I wanted to begin a serious schedule of workouts.

I wanted a boost, something that is not illegal but which would help me get past the hard training. Naturally, I turned to Andarine S4 SARM.

I began with a dosage of 25 mg daily split into two doses. I began to work out hard and added a lot of cardio. A great low-carbohydrate diet was thrown into the mix, and I made sure that I was at the gym five days a week.

After two weeks, I noted a remarkable change in my mood and strength. It was a feeling of great confidence. I could perform workouts longer and have developed a lot of endurance.

More than that, my recovery was quick and easy. No aching delayed onset muscle soreness that spoiled the morning after the huge workout.

After the first month, I had lost 8 pounds of fat and looked harder. It was really impressive. I know 8 pounds is not a lot, but I have sticky fat that does not come off too easy.

At the end of 16 weeks, my weight was 198 pounds, and my strength was awe-inspiring. My waist was down to 32 inches, and I looked trim, fit, and toned like I always wanted.


With no reservations, I would recommend Andarine S4. It is a genuinely good drug and I did not face any side effects from its use.

I have just finished a 16-week cycle and after an eight-week break, look forward to climbing back on another S4 cycle.

Just make sure you don’t buy it from a shady site. The real deal is not what is sold by many of these internet vendors. You must buy it from trustworthy dealers.

If you are going to take SARMs, you might consider S4 due to its efficacy in making an athlete look more muscular and ripped. It does not matter what type of sport you perform; Andarine S4 is going to make you great at it.
