XStreamForce SARMs – ANDARINE (S4) has been compared by researchers to have a similar effect to the anabolic compound Stanozolol, however with a slightly higher muscle protecting and muscle building effect. This product is great for body fat reduction and muscle protection during reduced calorie intake and/or intense cardio training.

What is Andarine? What effects can you expect from using this substance? Does it have any side effects? What should you know before you buy? Find answers to these and other questions in the following lines.

Due to the fact that S4 (Andarine) binds to androgen receptors, it can increase strength and build lean muscle mass without creating water weight, drying out the joints, stressing the liver, or causing severe suppression or shutdown. What’s more, there is strong evidence that S4 also helps prevent osteoporosis, meaning that it will strengthen bones and soft tissues within the body. Likewise, S4 is great at preventing muscle wasting for those who choose to use it as a bridge between anabolic cycles in order to keep muscle mass gains.

Andarine, also known as S4, belongs to the group of SARMs (Selective Androgen Receptor Modulators). It is one of the oldest substances of this type (first generation SARMs).

It was developed by GTX Inc. to treat osteoporosis, prostate disease and muscle-wasting diseases. Despite the lack of human research, it quickly gained popularity among athletes.

S4 is very often compared to Winstrol or Anavar. This is because, similar to the substances above, it allows for a “pre-start physique” – dry, strained, aesthetic muscles that give the illusion of lower body fat percentage.

However, unlike Winstrol, Andarine does not cause significant side effects as it is SARM.

SARMs only connect to androgen receptors, which are mainly found in muscles and bones. Androgen receptors play a very important role in building muscle tissue. Sex hormones combine with them and give them anabolic effects. To a large extent, it’s their amount and sensitivity in our bodies that determines our ability to build muscle.

There is no doubt that Andarine can be highly beneficial in the medical field and the recreational scene. However, clinical data on the drug is still limited, and that’s why it is only available as a research chemical. So, although you can easily purchase this compound, it’s wise to use it correctly to avoid medical complications. If you’re thinking of adding it to your bodybuilding plan, keep in mind that in almost all the studies where the drug produced positive results, the subjects were also under a proper training routine and a healthy diet.

Shredded Look – Like Winstrol or Anavar, the S4 gives you a distinct “muscle fullness” from week one. It gives the visual impression of a few percent less body fat and makes the veins more visible.
Increase in Muscle Mass – Andarine is one of the strongest SARMs in terms of anabolic power. It allows for quick and quality weight gain in a relatively short period of time (the effect is visible after about 3 weeks of use).
Greater Strength – It gives great strength gains due to its androgenic activity. The effects are visible after 2-4 weeks of administration.
Increased Bone Density – Primary use of Andarine. That is why GTX Inc. developed this product. By interacting with androgen receptors in the bones, S4 increases their density. This benefit is especially important for the elderly and those at increased risk of fractures.

A dose of 1-3 capsules per day for 5 days on and 2 days off per week of Stanazine (S4) is recommended. Each bottle contains 100 doses of use. Cycle Length: 8 – 12 weeks. Doses per vial – 100.
