Selective Androgen Receptor Sarm S4 Andarine Gtx-007 for
Bodybuilding CAS 401900-40-1
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 testoste and other anblic roids 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-roidal
androgen antagonist bicalutami as a lead compound.
SARMS such as S4 can cause muscle growth in the same manner as
roids, however unlike testoster and other anblic roids, SARMS (as
nonroidal 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
Comparing to roids/Prohormones ,what's advantages of Andarine/S4?
It is non methylated so it is not toxic to the liver or blood
pressure. Some suppression may be present at doses of 50mg+ run for
longer than 4 weeks, however a full PCT of prescription SERMs like
nolva or clomid is not necessary.
Anabolic roids Andarine Glucocorticoid Anti Inflammatory S4 GTX-007
No need for a long time period off between cycles; the recommended
time of period for normal roid cycles would be Time on + PCT, so
for a typical 6 week cycle and 4 week PCT, a user would have to
wait another 10 weeks after PCT to start another cycle where SARMS
recovery requires minimal rest in between.
A dosing protocol of 50-75mg for 4-8 weeks will give good recomp
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.
