How Does Andarine work?
Andarine binds incredibly well to the androgen receptors of bone and muscle. While it doesn't tend to impress in terms of building pounds upon pounds of muscle like trenbolone will, it has amazing effects on fat loss. Why? Andarine is the least anabolic, yet most androgenic of the SARMS. When androgenic hormones or sarms attach to the androgen receptors in your adipose tissue or fat (yes we have androgen receptors in our fat too) they trigger fat oxidation.
This SARM is selective and shows no noticeable prostate activity. Andarine proved to be poor at building muscle tissue at lower doses, but it did, in fact, build lean hard muscle tissue at higher doses. These tissue gains have often been compared to that of winstrol or anavar, but, of course, without the associated androgenic side effects. Andarine is especially outstanding at strengthening, preserving and even building bone mass.
 
Andarine's exceptional ability to help oxidize fat and keep your body from going catabolic while on a low calorie diet is its specialty. It will provide a hard, dry, lean look and increase vascularity. It provides notable strength and endurance even while in caloric deficit, and, at higher doses, it can even add hard muscle to your frame. Any other SARM stacks wonderfully with andarine, and the results will be compounded due to their synergistic effects. A stack of Andarine and ostarine (mk-2866), for example, would provide results arguably comparable to a stack of testosterone and winstrol. Again, SARMS are not steroids, and they provide less androgenic and anabolic effects as actual steroids, but the effects are very similar. Andarine can also be used by itself and provide fantastic results.
 
We choose to use Aluminum foil stand-up bags for several reasons. They fit into letterboxs, so all packages are delivered and not sitting in some post office someware. They are flexible bags resealable with the ziplocks and are excellent barriers against UV light, oxygen, odor, and moisture as the pouches are heat sealed. This  ensures your product is the same as when they where made and packaged.
