S23 (Mastorin)

S23 is categorized as a Selective Androgen Receptor Modulator (SARM) and is known for its selective impact on androgen receptors, resulting in fewer side effects compared to anabolic steroids or hormones.

Scientific studies have confirmed the ability of S23 to enhance strength and accelerate muscle mass growth without causing androgenic side effects. It also aids in faster fat tissue burning. Additionally, the use of this compound has shown a reduction in prostate size, which is beneficial for individuals with such concerns.

Benefits:

1. Building lean body mass:

S23 is considered one of the most potent atypical pneumocardiacs available in the market. It facilitates muscle building and fat burning simultaneously, allowing for recompensation even during a calorie surplus.

Studies on rats have demonstrated that S23 effectively reduces body fat and total weight.

Moreover, when researchers administered estrogens to induce sexual activity in rats and anticipated muscle mass loss, the rats treated with S23 exhibited additional muscle growth while countering the effects of estrogen.

2. Improved strength and endurance:

Users of S23 report noticeable improvements in strength and endurance within the initial weeks of their cycle.

Enhanced endurance enables longer and more intense training sessions, leading to improved fitness outcomes.

It's important to remember that regardless of the substances used, training and diet play crucial roles in achieving desired results. SARMs or steroids are tools that can facilitate the process but are not substitutes for proper exercise and nutrition.

3. Potential contraceptive effects in men:

S23 is being researched as a potential oral contraceptive option. Pharmaceutical companies have shown increased interest in S23 in recent months.

Studies on rats suggest that S23 can temporarily inhibit the hormones LH and FSH, responsible for signaling sperm production.

Current findings indicate that the effects are temporary, and sperm production returns to baseline shortly after discontinuation of the drug.

However, if considering its use, careful attention should be given to selecting the appropriate dosage. Studies on rats indicate that individuals who took higher than usual doses experienced normal or even higher-than-baseline sperm production.

4. No water retention:

According to user reviews, S23 does not cause water retention. This means that with proper nutrition and post-cycle therapy (PCT), individuals can maintain their weight without excess water retention, which can negatively impact aesthetics, particularly in the face.

5. Increased libido in women:

Research in this area is currently limited to cases of decreased libido resulting from menopause. Hypoactive Sexual Desire Disorder (HSDD) is typically treated with testosterone, which can have androgenic side effects like voice deepening or clitoral enlargement.

In contrast, S23 improves libido without the androgenic side effects associated with testosterone therapy.

6. Enhanced muscle appearance:

S23 not only increases muscle hardness but also improves muscle aesthetics. During a cycle, it can provide dry mass effects similar to those of Anavar or Trenbolone. Consequently, it is frequently used in competition preparation (although it is currently prohibited for professional use by the World Anti-Doping Agency).
