Why buy this product

S-23 by Magnus Pharma, also known as Mastorin, is a sports supplement designed to improve the performance of the training process in athletes. The drug is a sixth generation SARM. S-23 was created in the course of research, the main goal of which was to develop a compound that has all the positive properties of testosterone, and does not have significant side effects.

Once in the body of an athlete, S-23 begins to interact with androgen receptors in bone, adipose and muscle tissues. As a result, the production of ribonucleic acid is activated, the synthesis of motor and contractile proteins is accelerated, lipolysis is stimulated, accompanied by the release of fatty acids. These compounds become substrates for the production of adenosine triphosphoric acid, which is a universal source of energy necessary for the normal course of most biochemical reactions.

Effects of Taking S-23

Scientific research and practical experience in the use of the S-23 by athletes shows that it is one of the most powerful, if not the most powerful, SARMs that:

  1. increases and strengthens muscle mass;
  2. increases strength, endurance and reaction speed.=;
  3. increases bone strength;
  4. reduces adipose tissue;
  5. prevents muscle wasting;
  6. does not retain water;
  7. improves muscle definition.

Due to its properties, the drug is popular among athletes of various sports, such as bodybuilding, boxing, wrestling, mixed martial arts. Among bodybuilders, the drug is often used during the cutting cycle, since it practically does not retain water and helps to maintain the gained muscle mass.

Medical indications for taking S-23

The drug was developed for people suffering from muscle and bone wasting. S-23 only binds to androgen receptors in bones and muscles.

Application and dosage of S-23

Building muscle mass (daily dosage):

  • 10 mg for athletes weighing up to 80 kg.
  • 15-20 mg for athletes weighing over 80 kg.

The duration of the course is 6-12 weeks.

To achieve high results, it is necessary to increase the daily intake of proteins (at least 3 g per 1 kg of body weight), consume a sufficient amount of calories, and also conduct intensive training with heavy weights.

After 2 weeks of the course, you will see an increase in strength and muscle mass.

Do I need PCT (Post Cycle Therapy)?

Please note that the drug reduces the natural production of testosterone, so after the cycle it is necessary to carry out post-cycle therapy to quickly restore testosterone levels in the body to maintain the gained muscle mass.

Side effects

Unfortunately, while SARMs usually don't have any side effects, or have ones that aren't very troublesome, it looks a little different in the case of S23:

  • decreased testosterone production;
  • shrinkage of the testicles;
  • dark urine;
  • increased aggressiveness.
