S-23 SARM vs. RAD 140 | Which SARM is Better?

In the research world, SARMs are refining how researchers explore androgenic activity with precision. S-23 and RAD 140 have gained particular interest for their distinct molecular structures and targeted effects on androgen-sensitive tissues. 

Choosing the right compound for a specific research model requires a detailed analysis of its biological effects and study findings. This blog offers a research-focused comparison of S-23 and RAD 140 to support informed compound selection based on scientific goals. 

What are S-23 and RAD 140?

S-23 is a strong SARM designed for studying muscle growth and suppression of spermatogenesis in animal models. It may bind tightly to androgen receptors in tissues like muscle and bone.

RAD 140 (Testolone) is a research compound created to help scientists explore muscle growth and protect brain cells. It may show tissue-selective activity, meaning it might target muscles more than other body parts in clinical settings. 

Both compounds are for research use only. They are not approved by the FDA for human or animal use.

How do S-23 and RAD 140 work?

Both S-23 and RAD 140 are designed to bind to androgen receptors. These receptors are located in different tissues. When a compound like S-23 or RAD 140 binds to these tissues, it may activate processes like protein synthesis, which supports muscle and bone development.

• S-23 may bind with higher affinity than RAD 140 and may lead to a reduction in natural testosterone levels in lab models.
  
• RAD 140 may offer more selectivity, possibly supporting lean tissue growth with fewer side effects in test environments. 

S-23 and RAD 140: Feature Comparison

Feature	S-23	RAD 140
Receptor Binding	Strong	Selective
Muscle Growth	High	High
Testosterone Suppression	Likely Strong	Possibly mild
Half Life	~12 hours (in test models)	~16-20 hours (in test models)
Brain Activity	Not well-studied	May protect neurons

S-23 vs. RAD 140: Potential Research Applications

Tissue Anabolism and Androgen Receptor Modulation

• S-23 has shown potential to support muscle and bone development in research settings.
  
• In lab settings, RAD 140 may help build lean mass while also lowering body fat levels. 

Body Composition and Metabolic Activity in Test  Models

• Research suggests that S-23 might help remove fat and improve muscle tone in clinical subjects.
  
• RAD 140 could boost metabolism and help maintain lean body composition in test models.

Performance and Endurance

• Some researchers have observed better strength and training ability in animal models given S-23.

• Early studies suggest RAD 140 might improve endurance and speed up recovery after physical activity in preclinical trials.

S-23 and RAD 140 Side Effects: Comparison Analysis

Both SARMs may come with side effects in test environments:

• S-23: It may suppress natural testosterone more strongly. Some studies report changes in reproductive function in male animal models.
  
• RAD 140: It may slightly affect testosterone and liver markers in animal studies. It may have a better safety profile compared to S-23.

These effects are observed only in research settings, not in humans. 

S-23 versus RAD 140: Summary of Findings 

• S-23 may show stronger androgenic activity and support more muscle growth in research models.
  
• RAD 140 may have milder effects on hormones and might help protect brain cells in lab studies.

The better compound depends on the goals of your research model. 

S-23 and RAD 140: Stacking

In research, scientists sometimes study how compounds work together. This is called “stacking”. 

• S-23 and RAD 140 may be stacked in studies to explore synergistic effects on tissue growth.
  
• Always keep in mind that stacking may increase side effects in test subjects. 

S-23 SARM vs RAD 140: Which one is better? 

There is no definite answer to this question. Both compounds show promise in research. The best choice depends on what the study is focused on: 

• S-23: Stronger, more aggressive results.
• RAD 140: Balanced, possibly safer option for long-term models.

Each product includes a reference-grade Certificate of Analysis (COA). This verifies purity, identity, and concentration. 

Are S-23 and RAD 140 legal for research use?

In many countries, S-23 and RAD 140 are legal for scientific research. However, the FDA has not approved these compounds for human or animal consumption. Always check your local laws and use them only in approved lab settings. 

What are the recommended dosages for research?

There are no official doses for S-23 and RAD 140 because they are experimental compounds. In published animal studies: 

• S-23: Often used at 0.1-3 mg/kg in rodents
• RAD 140: Typically ranges from 1-10 mg/kg in animal tests

How are S-23 and RAD 140 administered in studies?

In lab tests, researchers usually give these compounds through oral solutions or injections. The method may depend on the compound’s stability and the study design. 

Conclusion 

S-23 and RAD 140 are powerful tools for studying androgen receptor activity and tissue growth. Each offers unique benefits depending on the specific goal. These compounds are still under research and are not approved for medical or personal use.
