Effective Orally SARM Andarine (S4) Raw Powder For Preventing Muscle Wasting
As a research chemical, S-4 belongs to a class of chemicals known as SARMS or selective
androgen receptor modulators. Like typical androgens, SARMS bind to the androgen receptor
however SARMS create selective anabolic activity.
Compared to testosterone and other anabolic steroids and pro hormones, the advantage of
SARMS such as S-4 is that they do not have androgenic activity in non-skeletal-muscle tissues.
S4 was designed for treatment of conditions such as muscle wasting, osteoporosis and benign
prostatic hypertrophy, using the non-steroidal androgen antagonist bicalutamide as a lead
As an orally active partial agonist for androgen receptors, S-4 is effective in not only maintaining
lean body mass but actually increasing it.
Andarine (GTx-007, S-4) is an investigational selective androgen receptor modulator (SARM)
developed by GTX, Inc for treatment of conditions such as muscle wasting, osteoporosis and
benign prostatic hypertrophy, using the non-steroidal androgen antagonist bicalutamide as a lead
Andarine is an orally active partial agonist for androgen receptors. It is less potent in both
anabolic and androgenic effects than other SARMs. In an animal model of benign prostatic
hypertrophy, andarine was shown to reduce prostate weight with similar efficacy to finasteride,
but without producing any reduction in muscle mass or anti-androgenic side effects. This
suggests that it is able to competitively block binding of dihydrotestosterone to its receptor
targets in the prostate gland, but its partial agonist effects at androgen receptors prevent the side
effects associated with the anti-androgenic drugs traditionally used for treatment of BPH.
Andarine S4 is a SARM that was developed for treatment of muscle wasting, osteoporosis and
benign prostatic hypertrophy. S4 is effective in not only maintaining lean body mass, but
increasing it while reducing body fat.
How does it work ?
Selective androgen receptor modulators (SARMS) bind to the androgen receptor and
demonstrate osteo (bone) and myo (muscular) anabolic activity.
Binding and activation of the Androgen receptor alters the expression of genes and increases
protein synthesis which ultimately builds muscle.
SARMS such as S4 can cause muscle growth in the same manner as steroids, however unlike
testosterone and other anabolic steroids, SARMS (as nonsteroidal agents) do not produce the
growth effect on prostate and other secondary sexual organs.
SARMS not only represent a new potential treatment option for a wide spectrum of conditions
such as muscle wasting diseases (from age-related to AIDS or cancer-related), but they also
have immense potential for muscle building for Bodybuilders, fitness and athletes.
S-4 in particular binds to the androgen receptor in muscle and bone to a third of the affinity of
A dosing protocol of 50-75mg for 4-8 weeks will give good recomp effects
Diet must also be optimized to where calories are just above maintenance with at least 30%
coming from lean sources of protein to get the best recomp effect.
Of course, the recomp effects could be even greater if stacked or combined with a more
anabolicSARM such as Ostarine.
A 50mg dosing protocol for 6-8 weeks is ideal for cutting purposes for the majority of users.
However due to the vision side effects, if running at these doses some like to follow a 5 on 2 off
protocol where S4 is used for 5 days followed by a 2 day break (then this cycle is repeated).
