Testolone (RAD-140) | 40mg/1,5ml

What is Testolone (RAD-140)?

Testolone, also known as RAD-140, is one of the most popular selective androgen receptor modulators (SARM), designed to achieve a strong anabolic effect without the serious side reactions typical of traditional androgenic compounds. The molecule is engineered to act primarily on muscle and bone tissue while maintaining hormonal balance and avoiding stimulation of unwanted receptors.
RAD-140 has been widely studied for its strong affinity for androgen receptors and its notable potential to stimulate muscle growth, improve strength, and accelerate recovery processes. For this reason, it is a preferred subject in research focused on physical optimization, body recomposition, and hormonal support under different models of stress and load.

Mechanism of action of Testolone (RAD-140):

Testolone binds selectively to androgen receptors and activates specific genes responsible for protein synthesis, muscle regeneration, and metabolic efficiency. This leads to stimulation of muscle growth, increases in strength, and improvements in bone tissue density.
One of the main advantages of RAD-140 is its ability to exhibit an anabolic effect comparable to that of testosterone without converting to estrogens or causing significant androgenic activity in undesired tissues. This makes it suitable for research requiring a strong but controlled anabolic influence.

Potential scientifically supported benefits of Testolone (RAD-140):

RAD-140 has been the subject of numerous laboratory analyses and scientific studies. The most commonly observed potential effects include:

• Marked increases in muscle mass and strength in short and mid-term research protocols;
• Improved tissue recovery after intensive load or catabolic stress;
• Preservation of muscle mass during caloric deficit or hormonal imbalance;
• Increased bone density and robustness;
• Lack of aromatization, which minimizes the risk of water retention or hormonal fluctuations;

RAD-140 is widely used in research models related to sports physiology, recovery after trauma, and physical adaptation under hormonal disturbances.

Comparison of Testolone (RAD-140) with other SARMs

Testolone, also known as RAD-140, is one of the most potent SARMs, developed to achieve maximal anabolic impact on muscle tissue without the typical side effects of androgenic steroids. This places it in direct comparison with other leading compounds such as Ligandrol (LGD-4033), S23, and Ostarine (MK2866).
Compared to Ligandrol, which is also used for muscle growth, RAD-140 demonstrates a more pronounced anabolic action and faster results, especially in short, intensive research protocols. Unlike Ligandrol, RAD-140 also shows potential for neuroprotective effects due to its interaction with certain neuroreceptors, which makes it of interest in models related to cognitive support.
Compared with S23, Testolone offers a better balance between potency and tolerability. S23 often leads to strong suppression of the testosterone axis and requires strict hormonal control after completion of a cycle. RAD-140, despite its potency, demonstrates a more controllable profile, especially with reasonable dosing and limited duration.
In the context of Ostarine, which is milder and suitable for beginners or long-term protocols, RAD-140 is positioned as an advanced alternative for situations where significant increases in strength and muscle mass are targeted over a shorter period. Unlike Ostarine, RAD-140 is not used primarily for maintenance but for active building.
Testolone is often preferred when maximal anabolic effect, accelerated recovery, and high efficiency in short cycles are sought without the need for androgenic preparations.

Dosage and application of Testolone (RAD-140) in research protocols:

Recommended research scheme: 6 units once daily, for 4–6 weeks, followed by a 2–4 week off period.

1 unit = 26.66mcg.

Total amount in pen: 150 units

Possible side effects of Testolone (RAD-140):

Despite the high effectiveness of RAD-140, observations include some side effects, especially with prolonged use or higher doses:

• Possible temporary suppression of natural testosterone production;
• Mild imbalance in the hormonal axis with longer protocols;
• Individual reactions related to increased sensitivity to androgenic stimulation.

Adhering to optimal dosing and controlling the duration of application play a key role in limiting the manifestation of side effects.
