Popularity of SARMs has grown rapidly over the past few years. Selective androgen receptor modulators (SARM) are a class of therapeutic compounds that have similar properties to anabolic agents, but with reduced androgen properties. This allows SARM to get advantages of the specificity of androgen-receptor, the selectivity of tissue and lack associated with steroids side effects.

Some of the potential side effects of anabolic steroid include: acne, liver damage and testicular shrinkage in men, as well as voice enhancement, facial hair growth and upper back, abnormal menstrual cycles in women. SARMs give a little less anabolic effect than steroids, but do not give such unwanted side effects. There are hundreds of possible SARMs, but it is possible to highlight the main, easily accessible at the moment and the most applicable in bodybuilding. The following drugs have many reviews in the world of bodybuilding:

  • Ostarine (MK-2866)
  • Anabolic (LGD-4033)
  • Andarin (S-4)
  • Cardiris (GW)
  • Stenobolic (SR9009)

SARMs in bodybuilding

One of the most interesting aspects of SARMs is that they differ in anabolic-androgenic ratios from 3:1 to 90:1, in contrast to the analogous ratio of steroids 1: 1. In other words, gynecomastia will not develop in men, and women will not suffer from virilization. Athletes can use SARMs in combination, or as a replacement for traditional anabolics. Here are just some of the benefits of SARMs:

  • Increase muscle growth
  • Preventing muscle loss during cutting
  • Strengthening rehabilitation
  • Reduce recovery time after exercise
  • Increase fat loss
  • Increase endurance
  • Reducing fatigue

The benefits of SARMs compared to steroids:

  • Similar positive effects on testosterone
  • No harsh liver toxicity from methylated compounds
  • Legality

One of the main characteristics of SARMs is that they are difficult to turn into an enzyme called 5-a-reductase, which causes many undesirable side effects of steroids.

SARMs are also resistant to enzymatic aromatase, which converts testosterone into estrogen. Finally, since SARMs are less powerful than conventional steroids, they do not inhibit natural testosterone production, making recovery much easier. They are also popular among athletes because they are difficult to detect when testing for doping.

For many, the advantage is that SARMs can be taken orally, which means that you do not have to tolerate painful injections and worry about the formation of abscess, needle purity and hygiene.

Briefly about the popular SARMs

Ostarine (MK-2866) – this SARM is the most famous. It is best used to maintain muscle mass when there is a calorie deficit. Used by athletes and bodybuilders to gain muscle mass and lose fat. MK-2866 is also useful for damaged ligaments, bones and tendons. Ostarine can suppress your natural testosterone production in longer programs with higher dosing. The average duration of the program is from 6 to 10 weeks at a dose of 10 mg to 25 mg.

LGD-4033 is a SARM, like Ostarine, but 12 times more powerful! If Ostarine is best used in a cutting program, LGD has established itself as a good muscle gain amplifier. It has a half-life 24 – 36 hours, so the daily dosage is optimal.

Cardiris (GW-501516) is used to increase the metabolism of fatty acids. This SARM can stimulate the reduction of cholesterol and increase endurance. It can be combined with Trenbolone as it denies steroid side effects and enhances its positive effects. Cardirin is commonly used in daily doses of 10-15 mg every day for 8 weeks, although some prefer to use it in programs of 8-12 weeks at 20 mg every day.

Stenabolic (SR9009) reduces inflammation, increases stamina, stimulates fat burning and the growth of mitochondria in muscle cells. It is thought to be ideal for improving endurance and fat loss at the same time. The ideal dosage is 20-30 mg every day for 4-8 weeks.

Andarin (S-4) is an ideal SARM for the creation of resilient muscle tissue. Andarin is best known in the bodybuilding community for his ability to maintain, strengthen and build mass. S4 also gives a sharp increase in strength and endurance. It is dosed at 50 mg each day.

Reviews about SARMs differ. Some athletes do not want to risk and waste time, preferring the old version with steroids, but still, over time, SARM fans are becoming more and more. After all, the side effects of steroids, which are often irreversible, are increasingly beginning to frighten athletes.

SARMs have been banned by the world anti-doping agency (WADA) since 2008. They can be used to improve performance in sports because of their anabolic properties, as well as the ability to stimulate androgen receptors in muscles and bones. They are currently banned in the category of “other anabolic agents” in section S1.2 of WADA prohibited list.
