S-4, also known as Andarine  or GTx-007, taken as oral.

For treatment of conditions such as muscle wasting, osteoporosis and benign prostatic hypertrophy. It is less potent in both anabolic and androgenic effects than other SARMs. Today, it is popularly used and sold as a research chemical, which is used by athletes who seek to get all of the strength benefits and lean muscle gains without the harmful side effects observed with anabolic steroids. Moreover, Raw S4 powder is also used as part of steroid stacks to improve a cycle without adding more side effects, or aromatization.

Raw Raw S4 powder (401900-40-1)

The S4 SARM is used for pretty much everything. Cutting, bulking or recomping is no issue with this selective androgen receptor modulator.

In a cut, you can definitely expect it to help you tight and vascular. It’s known to increase strength and mass even though you are consuming fewer calories.

In my opinion, S4 SARM raw powder really shines when bulking.

Within a week or two you will start gaining a lot of strength and size. Even at a lower dosage of 50mg.

And the great thing is that this SARM is considered being a clean compound. You won’t be having any water retention or bloat during a bulk.

It definitely belongs to one of the more powerful SARMs. I have no doubt in my mind that it is perhaps even stronger than LGD4033.

Raw S4 powder (401900-40-1) Mechanism of Action

Just like all other SARM drugs, S4 raw powder works by fusing to the receptors. This operation is similar to how steroids operate. The only difference is that it excludes the side effects and disadvantages that are associated with using steroids. S4 is formulated to specifically zone in on strength, performance, and muscle building.

The activation of S4 raw powder in the body is selective. This means that it selects the tissue that it wants to work with and improve the tissue considerably while ensuring that the other parts of the body are not injured.

It could make your muscles hard, vascular and dry right from week-1 onwards. Somewhat like Winstrol, only milder.

To add to this, it creates the perfect anabolic environment in the body allowing other compounds to kick in.

S4 raw powder was all over the place. People were adding it to cutting stacks, bulking stacks, body recomposition programs.

That was until anecdotal reports of vision side effects started to do the rounds.

At first the reports were mainly about seeing incorrect colors and the yellowish tinge to things. Sort of like seeing the world in Sepia.

But when reports about peripheral blindness began to hit, S4 became the bête-noir of SARMS lovers.

So much so, that sales almost dipped to zero. No one would want to mess with their vision after all.

Benefits of Raw S4 powder (401900-40-1)

S4 is mostly used for cutting, bulking and recomposing.


using S4 raw powder increases fat oxidation in the body and it reduces lipoprotein lipase in the body. S4 ensures that the body does not lose its muscle mass during a calorie deficit. Cutting cycle takes about 12 weeks.


Just as the name implies, bulking means strength without needless inflation and water retention. The bulking effect of S4 is not always too exceptional, but it ensures that the body does not lose any of the strength it gathered throughout the cycle.


This is the process of striping the body of fat and increasing muscle mass at the same time. S4 promotes lean body mass and increases body functionality.

Recommended Raw S4 powder (401900-40-1) Dosage

S4 is like a milder version of Winstrol. It’s really strong at low dosages of 25 to 50mg. Despite it being a quite mild SARM, it’s actually really strong.
