Other Names: Andarine, Andarin, S-4, S-40503, GTx-007
Mol. mass: 441.357 g/mol
Half life: 2.6 hours.
Melting Point: 70-74 °C
Storage: Room temperature
Appearance: Pale yellow fine powder, odorless, acrid bitter taste.
Solubility: Soluble in DMSO (85 mg/mL), Water (< 1.2 mg/mL), and
Ethanol (85 mg/mL), it is also soluable in Propylene Glycol and
SARMS function by tying to the AR resulting to anabolic activity.
Due to this fastening and stimulation, more protein is produced
which allows muscle building. S4 can trigger muscle development in
the same way as steroids, but minus the same unwanted side effects,
the latter has on the prostate and other sexual organs.
S4 is a SARM with utmost androgenic effects as it around 33% of the
strength of testosterone when attaching to AR. S-4 also increases
the amount of muscle mass produced by desensitizing the AR to the
individual's natural testosterone to influence a stronger effect.
S-4 is by far the most versatile SARM ever created. Not only is it
the first SARM approved for a stage 2 research study, it has become
the most analyzed and investigated SARM so far. After the discovery
of its anabolic potential, the primary purpose of S-4 aimed to
develop an alternative treatment to age-related muscle wasting,
osteoporosis, and similar symptoms of hypogonadism, or end-stage
Aside from preserving lean body mass, S4 can also help improve it.
From a stage 1 study, S-4 has provided evidence of a 3.3 lbs
increase in less than 90 days with no increases exercise or change
in daily diet. An unintended side effect (or benefit if you will)
is the decrease in body fat [Chen et al., 2005; Gao et al., 2005;
Kearbey et al., 2007]. Decreases in body fat are dependent on the
person's genetics, but it will definitely have strong effects on
the body's ability to oxidize fatty tissue. S-4 was found to not
only have a great affinity (potency in binding to androgen
receptors), while also presenting greater anabolic effects than
some traditional steroids [Kearbey et al., 2007].
Aside from its muscle building advantages, S4 won't cause liver
damage, can prevent gynecomastia (enlarged breasts in men) and can
help boost your overall health.
Usage of S4:
1)For Cutting (best use of S4)
Andarine's properties are very alike with steroids Anavar and
Winstrol, the only difference is that S4 can better provide lean
muscle gains. In fact, there have been many cases of bodybuilders
gaining up to 3 pounds of lean muscle while on a caloric deficit!
S4 displays the same binding resemblance to AR, hence presenting
similar fat burning effects. S4 can also minimize LPL (lipoprotein
lipase) - an enzyme that causes lipid accumulation and plays a role
in storing adipose tissue (excess body fat). The AR oxidizes this
adipose tissue and uses it as its preferred energy source, allowing
the body to decrease excess fat at an amazing rate.
It also improves vascularity for that "aesthetic" chiseled look
with minimal to no water retention. Unlike steroids, it won't
affect your joints but reinforce muscle mass and power instead. You
can also say goodbye to painful pumps.
Recommended Dosage: 50 mg for 6-8 weeks.
Use S4 with a more anabolic SARM such as Ostarine for better recomp
results as you're aiming to gain muscle while losing fat.
Recommended intake is 50-75 mg for 4 to 8 weeks.
S-4 isn't the sarm that comes to mind when we think "BULKING", but
it's properties in muscle gain shouldn't be overlooked. During the
holiday season, many people take advantage of the excess food and
snacks available and jump on some well known bulking SARMs such as
LGD 4033 or RAD 140. While there isn't an enormous 15 lb leap in
muscle like these "bulk specific" products, S-4 can provide
relatively large muscle gains and utilize these excess calories to
provide an extra 8-10 lbs in muscle while also keeping the body
relatively lean. This steady increase in muscle mass can limit the
amount of work one needs to do for a leaner summer body.
The Benefits of S4 over Steroids:
1.Very minimal growth on secondary sexual organs such as the
2.The LDL/ HDL ratio is not affected which makes it a low
3.0% chance of aromatization, male breast lactation, or rise in any
other female characteristic during the post cycle recovery.
4.Testosterone is not diminished in any capacity during the post
5.Very exclusive in tissue selection and growth which means it will
not cause heart enlargement or damage to neighboring organs.
6.SARMs do NOT require the utilization or devouring of liver
enzymes to activate their anabolic effects. This eliminates any
risk of hepatotoxicity or hepatitis.
7.Although SARMs such as S-4 are not as powerful as comparable
steroids such as Winstrol, they do not require the extensive post
cycle therapy and can be cycled back to back throughout the year.
Over the course of a year, obtaining the same results is very
8.SARMs is very female friendly and does not cause excessive
masculine features such enlarged sexual characteristics.
9.S-4 has overall presented larger increases in muscle mass than
How to use S4 safely?
To negating any side effects, S-4 should be dosed at 5 days on 2
off at 50mg. If you go above 50mg you will lose some night vision
if the quality of S4 you got is good. S-4 has a very short half
life, 2.6 hours, so it would be perfect to use as a pulse, 3 times
a week 2 hours before training should give excellent strength and
hardening results. Both those protocols will reduce the yellow eye,
and night vision problems. Remember, a PCT (post cycle therapy)
should be always carried out after using S4. If you want the
effects faster, the recommended dosage for cutting is 50 mg for 6-8
weeks. It should be used every day then take 2 days off for the
duration. Taking S-4 daily for the length of the cycle can lead to
obvious changes by eyesight.
Running 20mg a day 6 days on 1 off for 6-10 weeks not only reduces
body fat, but it has been used by me in conjunction with the only
other compound I’ve ever seen reduce gyno - Letrozole (femara).
Using 0.5 mg of Letrozole 3 x a week in conjunction with the S4
shows great promise in reducing steroid induced gynecomastia
