50MG/ML - 30ML | MADE IN USA 🇺🇸


Andarine, more commonly known as S4 is the original SARM. Scientists discovered that while this molecule is not shaped like a steroid it does activate androgen receptors selectively in the body, favouring those in skeletal muscle, bone, and connective tissue over those in the scalp and prostate. This led to an explosion of research into molecules that selectively activate the androgen receptor (AR). S4 exerts its selectivity by having a higher binding affinity to these androgen receptors. In spite of being the first SARM developed, Andarine is still considered by many researchers to be one of the best SARMs for cutting body-fat.

S4 Andarine Benefits from Clinical Research

S4 Andarine has displayed multiple effects in vivo, including:

  • Effective for Cutting Body Fat
  • Improved Bone Health
  • Supports Prostate Health
  • Promotes Lean Muscle Mass

Potential Side Effects of Andarine

 S4 is the oldest and one of the most well studied SARMs but its side effects and severity are still being learned. It is reasonable to believe that some non-androgenic side effects of anabolic steroids such as increased hematocrit, insomnia, lethargy, and liver damage may result from the use or abuse of Andarine.

While anecdotal reports rank S4 as mild on side effects compared to other SARMs, it does have one side effect present at higher quantities that is unusual to other compounds and that is a temporary slight yellowing of the vision and reduction in night vision.

Why is Sports Technology Labs the best place to buy Liquid S4 online?

If you’re trying to figure out where to buy S4 online, there certainly seem to be plenty of choices out there. Sports Technology Labs is the best place to buy Andarine online because of their consistent, verifiable high quality products, safe bottling and packaging.

Not all companies offering S4 for sale are alike—or equally trustworthy. To buy S4 from a randomly selected website is dangerous, even if the price looks reasonable, because you can’t be certain about their quality-control processes. At Sports Technology Labs you can find the highest quality SARMs for sale anywhere on the internet.

When you buy SARMs from Sports Technology Labs you are choosing the highest quality ingredients. Minimum 98% pure compounds tested and certified by accredited American third party labs, suspended in USP grade (the highest grade) PEG400, bottled in America. Their products come in glass bottles with fixed glass droppers to prevent the leaching of unwanted plasticizers like BPA, and prevent contamination between testing with external measuring tools. 

This preparation is for research purposes only and is not approved by the FDA for human consumption.
