SARMs – How They Work in The Human Body?

SARMs, which is an abbreviation of Selective Androgen Receptor Modulators is a class of drugs consisting of androgen receptor ligands. In chemistry, the word ‘ligand’ is used for a molecule or a substance which binds to another (mostly a metal). A ‘receptor’ is that part of the human cell which responds to substances specifically. In simple terms, every receptor type in the body has a particular shape and does not allow every chemical substance in the body to bind. This means every class of receptor recognises specific molecules. The ‘androgen receptors’ is a class of receptors on the cells of human body which is activated by the binding of androgenic hormones which include testosterone and dihydrotestosterone. The testosterone, a prime ligand for the androgenic receptors and a hormone produced by the male reproductive organs, the testes, has important functions in the body, few of which include maintenance of sexual function and development of sex organs (1). SARMs are intended to have the same effects as androgenic anabolic drugs such as steroids and hormones such as testosterone.

SARMs – When are They Required?

There are certain conditions in which the testosterone level in the body decline. This results in presentation of specific signs and symptoms associated with disruption of body functions due to testosterone deficiency. The levels of testosterone naturally goes down with the age. Therefore, older men are more likely to be suffering from low testosterone levels. However, few other conditions have been reported to cause low levels of this hormone. These include injury to the testes, chemotherapy or radiotherapy, kidney disease, liver disease, AIDS, hypogonadism (a condition characterised by negligible production of sex hormones), use of opioids and disorders of thyroid glands. (2).

The testosterone replacement therapy is a widely used treatment option for men with low testosterone levels. While the valuable effects of testosterone are infrequently disputed, there is a scarcity of the literature on the risks of testosterone use (3). A study stated that patients receiving long-term therapy with methyltestosterone had abnormal liver-function tests and abnormal liver scans (4). Another research stated that in older men with high prevalence of chronic disease, the application of a testosterone gel was associated with an increased risk of cardiovascular adverse events (5). However, few other studies have quoted controversial statements. If the association of testosterone therapy with prostate cancer is chalked out, there are again controversial statements quoted in different researches. To cut short, in men undergoing this therapy and have been previously treated for high-risk prostate cancer, this therapy should be reconsidered (3).

The development of SARMs and research being done on this class of drugs in comparison with testosterone therapy provide an insight to the attractive outcomes according to which, SARMs, due to their selective nature, can be the source of positive effects similar to testosterone and specifically on muscles and bones, without any toxic effects on other organs of the body (1). The potential of SARMs is that they can maximize the positive attributes of steroidal androgens while minimizing negative effects, thereby providing therapeutic options for various diseases, including osteoporosis.

Low Risk of SARMs – Evidence-Based Statements:

  1. RAD-140 (Testolone): In an animal study (6), RAD-140 by Radius Health, Inc., also referred as ‘Testolone’, was evaluated for its efficacy and tolerability, it was stated that the drug, at a dose 10 times greater than the fully effective dose caused minimal rise of the liver enzymes. Furthermore, it was stated that the drug caused an increase in the muscle weight of experimental animals at a lower dose than that required to stimulate prostate weight increase. The authors concluded that,

“RAD-140 has excellent pharmacokinetics and is a potent anabolic in nonhuman primates as well. We believe the overall preclinical profile of RAD-140 is very good, and the compound has completed preclinical toxicology in both rats and monkeys.”

Another study in which the role of Testolone was discussed in context with treatment of Alzheimer disease, provided an understanding of the association with the low testosterone level and development of Alzheimer disease. The study assessed the effect of Testolone on brain and prostate glands of animals and the results proved the neuro-protective and prostate-protective effects of the drug (7).

  1. MK-2866 (Ostarine): Ostarine (Enobosarm, MK-2866 or GTx-024) is a nonsteroidal SARM that has been or is being studied in several phase II and phase III clinical trials in patients with cancer cachexia, sarcopenia, breast cancer, and stress urinary incontinence (8).

One of the chief effects of androgen deficiency is the disturbance in the lipid (fats) metabolism resulting in obesity and increased risk of type II diabetes (9). An animal study in which the effect of Ostarine was probed on the fat cells of rats and compared with testosterone, it was stated that the SARM drug regulated fat metabolism similarly to testosterone (10). A research published in 2016 also documented Ostarine to have significant impact on increasing muscle mass (11).

Low Cost of SARMs:

HGH (human growth hormone) which is responsible for the upregulation of growth in children and adolescents and specifically muscle and bone growth has been synthetically developed for treating case of poor growth. MK-677 or ibutamoren, another SARM, does the same by increasing the secretion of growth hormone. Interestingly, the receptors for ibutamoren in the brain are located in the region which controls mood, pleasure and cognition and therefore, the drug may have an effect on these areas too.

One way to enhance your HGH levels regardless of age, or other factors, is to use injectable HGH. The reported cost of injectable HGH was approximately $250 a month in till the year 2003. The current price has elevated since then. To condense this cost related talk, HGH can cost thousands of dollars a month. On the other hand, ibutamoren can be bought at a very reasonable price.

SARMs – Potent Anabolics:

The word ‘anabolic’ in medicine refers to building up. The anabolic effects of testosterone and synthetic drugs promote protein and collagen synthesis, and increase muscle size and bone metabolism. The anabolic to androgenic ratio of testosterone has been specified as a standard to be 1:1. The ratio is higher and reaches 30 for few other anabolic steroids. This ratio is different in SARMs and depend on the drug in this broad category. Preclinical animal studies peg LGD-4033’s anabolic to androgenic ratio at 500:1 which is quite significant and the figure itself remarks on the high anabolic potency of the LGD-4033, another drug from the SARMs category.

SARMs are undoubtedly one of the hottest trends in the health & fitness community. Whether you’re an athlete getting ready for a competition, or you’re simply looking to get in shape (or get back in shape), SARMs are one of the only products on the market that can produce relatively significant results with little-to-no side effects. With that in mind, finding the best place to buy SARMs for sale can be quite challenging. Here are 3 things you should know before googling “Sarms Where to Buy”.

1) Look for Pharmaceutical Grade SARMs

But… what does “pharmaceutical grade” even mean? Simply put, this fancy combination of words qualifies the product as being at least 99% pure. A recent study testing the SARMs of many popular companies found at least 35% of them sell SARMs that are 70% pure and less. Others even claim they have SARMs for sale but are selling cheaper alternatives instead.

Without getting into much detail, it is important that you verify the purity of these SARMs for sale via lab tests.

2) Price isn’t EVERYTHING

One way some big companies justify putting their SARMs for sale at sky-high prices is by claiming they are the only supplier to be trusted for quality. Consumers fell for this marketing scheme over & over again in the past 10 years. Word of mouth quickly goes around about these “trustworthy” suppliers. It spreads to their friends & family, before spreading to more people. Sounds similar to how rumours spread? Exactly.

How To Lose Fat: Soluble Fiber Benefits!
Obesity can be measured using many methods. A simple and easy way to find out your weight is on the less healthy side is to measure your waist. When the waist circumference is 35 inches or more in women (or 40 inches or more in men), the individual is then considered to be obese. Stomach fat isn’t simply about how garments suit your body, but the health issue that might come with visceral fat, the kind of fat that surrounds your organs around the stomach area. Excess stomach fat is one of major risks for type 2 diabetes. Despite the fact that you look thin outside, you have an increased risk for type 2 diabetes if you have high levels of visceral fat. Losing fat in this area can be quite challenging for many. Extensive research has been conducted to discover how to lose stomach fat fast.

The great news is that there many effective ways to lose the stubborn belly fat as suggested by scientific studies. Reducing abdomen fat requires you to change your lifestyle, especially with regards to eating patterns and physical exercise. The first thing you can do is reduce carb intake, especially refined (simple) ones. Overweight people need to limit daily carb intake to up to 50 grams. Nevertheless, you can’t do it in a dramatic way, especially if you’re utilized to consuming high carb meals. Replacing refined carbohydrates, like bread and cookies, with unprocessed starchy carbohydrates like those from vegetables and fruits might help in improving your metabolism and overall health.

In the end, this will ultimately reduce stomach fat. Soluble fibers are essential for diet programs, as they serve to soak up excess water and form gels that promote the elimination of food in the stool. Drinking lots of water is ideal when increasing soluble fiber intake. Furthermore, research shows that soluble fiber promotes weight loss by keeping longer satiety. Therefore, you may need to eat less calories in a natural way, since you feel full for a longer period. One study shows that for every 1 gram increase in the intake of soluble fiber equals to 3.7% decrease in the stomach fat so long as they’re taken over the long term.

If you wish to lose stomach fat fast, make sure to include foods high in soluble fibers, like avocados (max half per day), blackberries, Brussels sprouts, flaxseeds, and legumes into your daily menu.

SARMs and Why They’re Being Used as Steroid Alternatives

SARMs stands for selective androgen receptor modulators. SARMs are highly selective in their nature. They selectively target muscle and bone tissue in the body, causing steroid-like benefits without the side effects of anabolic steroids. They do not target the liver, hair or the prostate in the same way anabolic steroids do. SARMs are not steroids.

To maximize the physical benefits of SARMs, proper nutrition and intense training are optimal. Strength gains can be seen in as little as 2 weeks. Body composition changes can be noticed in 2-3 weeks depending on the individual’s diet & training. The most effective SARMs cycles are done over a period of 60-90 days, for most fitness goals. This is because SARMs need about 2 weeks to fully kick in, and studies show that the body begins to adapt after about 90 days. Therefore, cycling off for a period of about 3-4 weeks is the typical procedure in the sport & fitness community.

SARMs increase muscular size by causing an increase in lean muscle mass. Studies show that they increase muscular mass over 12 weeks (Dubois et al, 2015). The results depend on that the SARM and the dose. Studies also show they can boost sex drive as well as testosterone without that the steroid-like side effects. Many more studies published on NCBI show SARMs such as MK-2866 & RAD-140 essentially cause no androgenic side effects, and their effects on prostate weight are insignificant. This may indicate their tolerability by females as they do not cause androgenic side effects such as an increase in body hear, a deepening of the voice, aggression, etc. MK-2866 (Ostarine) is currently undergoing clinical trials to treat stress urinary incontinence in women (2018). RAD-140 is also undergoing clinical trials to treat breast cancer in women (2018).
