Andarine (otherwise known as s4 or Andarine S4) is a product that can help to prevent muscle wastage and support muscle mass development, so you look chiseled, hard and lean.

In many ways it works and operates like an extreme agent, but with less of the negative side effects. Not only is it fast-acting – producing muscle gains within a smaller time frame – it is also an incredibly strong compound.

Now S4 is not like your average product, as it is stronger and more powerful. Add into the equation the fact that it causes fewer side effects (because it binds selectively and not with every androgen receptor it encounters) and is anabolic, and what you have got is an easy way to build up muscle fast.

It can also offer the following benefits:

    • Muscle hardening

      Andarine can help to make your muscles harder, drier and more vascular in as little as a week, making it ideal when prepping for competitions. Users recommend adding it to your stack during the last 6-8 weeks of your cycle, so you’ll end up looking ripped and chiseled. It can also give you muscle pumps that last all day long – not just when you’re lifting weights.

    • Increased strength

      You will notice a difference to your strength and endurance in as little as two weeks. In fact, some users have reported being able to break previous best lift records by week 5 of their cycle with this S4.

    • Fat loss

      It is not entirely known ‘how’ S4 helps your body to burn fat; however, the leading theory is that it suppresses the production of Hormone Sensitive Lipase (HSL) which is responsible for regulating the metabolism of stored fat (by signaling your body to utilize stored fat for energy).

      Users have reported losses of up to 7lbs of fat – as well as lean muscle mass gains – when they took 50mg of S4 for 6 weeks.
