A SARM such as S-4 is a good example. S-4 attaches to the AR and sticks to it; each time the AR interacts with testosterone, S-4 forces it to produce genes that exclusively benefit muscle and bone growth. In other words, S4 is a form of SARM that attaches to the androgen receptor (AR) the same with regular androgens, the only variation is that S4 generates selective anabolic activity.
As said earlier, 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 renal disease.
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.
Recommended dose for cutting is 50 mg for 6-8 weeks. You should use it every day then take 2 days off for the duration. Taking S4 daily for the length of the cycle can lead to changes in eyesight.
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.
*Take 2 days off when taking S4 (repeat the cycle after the 2 day break) to avoid vision side effects.
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.
