Mastorin (S23)

S23 belongs to a group of agents called SARMs (selective androgen receptor modulators). These agents are known to have a selective effect on androgen receptors, causing far fewer side effects than anabolic steroids or hormones.

So far, studies have confirmed S23’s ability to increase strength and accelerate building muscle mass without androgenic side effects. This substance also allowed burning adipose tissue much faster. Also, during the use of this drug, a reduction in the prostate was observed, which is excellent news for people with this problem.

Advantages:

Helps in building lean body mass.

S23 is one of the most potent atypical pneumocardiacs currently available on the market. It allows you to build muscle and burn fat at the same time, so that even with an excess of calories you will experience greater recombination instead of typical mass.

Results from rat studies show that S23 simultaneously reduces fat and total body weight.

The scientists also gave the rats estrogen to induce sexual activity and see if they would lose muscle mass as a result. Instead of the expected results, rats receiving S23 gained additional muscle tissue offsetting the effects of estrogen.

Studies have also shown that S23 can prevent glucocorticoid-induced muscle damage. It is a powerful anti-inflammatory drug, the chronic use of which reduces muscle tissue. The prescription SARM counteracts the adverse effects of glucocorticoids by increasing muscle mass and improving strength and endurance.

Improves endurance and endurance.

S23 testers report significant improvements in ​​strength and endurance in the first few weeks of your cycle.

Greater endurance means you can train longer and harder, which leads to better training results.

Remember that regardless from the substances used, training and diet always play a fundamental role. SARMs or steroids are just a tool that makes it much easier to get the desired results.

It can act as a contraceptive for men.

There is a lot of research going on around the world to find oral contraceptives. S23 is one of the candidates that pharmaceutical companies have paid increasing attention to in recent months.

Studies in rats show that it can temporarily block the hormones responsible for signaling sperm production, LH and FSH.

The current results show that the results are temporary and that once the drug is stopped, sperm production returns to baseline within a short period of time.

However, if you want to try it, you should pay particular attention to choosing the right dosage. Studies in rats show that people who took much higher doses than usual had normal or higher sperm production than baseline.

Does not cause increased water retention.

According to user reviews, S23 does not cause water retention. This means that with proper nutrition and PCT, you can maintain 100% of your weight post-cycle. Furthermore, as is known, increased water retention has a negative effect on aesthetics, especially on the face.

Increases libido in women.

This effect is currently only studied in cases of decreased libido caused by menopause. The problem is known as hypoactive sexual desire disorder (HSDD) and is usually treated with testosterone. Unfortunately, this type of therapy can have side effects, such as a deepened voice or an enlarged clitoris.

Unlike testosterone, S23 improves libido without the androgenic side effects.

Full muscles.

This substance not only increases muscle hardness, but also improves muscle appearance. During the cycle, you can experience dry mass effects similar to Anavar or Trenbolone. For this reason it is often used in the preparation of competitions. (It is currently on the WADA list, so cannot be used by professionals).
