What Is RAD 150 (TLB 150)?
RAD 150, also known as TLB 150 or TLB-150 Benzoate, is an esterified version of RAD 140 (Testolone), a selective androgen receptor modulator designed for research purposes.
RAD 150: An esterified SARM created by attaching a benzoate ester to RAD 140, resulting in improved chemical stability, extended half-life, and enhanced bioavailability.
The key difference lies in the esterification process. When a benzoate ester is attached to RAD 140, it creates a more stable compound that the body processes differently.
This modification extends the half-life from approximately 16-20 hours (RAD 140) to an estimated 48-60 hours (RAD 150). The result may be more consistent blood plasma levels and potentially more stable effects.
RAD 150 was developed to address some limitations of RAD 140, including its relatively short half-life and the need for daily dosing. Researchers have noted that the esterified version may provide more predictable pharmacokinetics.
Key Characteristics of RAD 150
- Chemical Name: TLB-150 Benzoate
- Classification: Selective Androgen Receptor Modulator (SARM)
- Half-Life: Approximately 48-60 hours (estimated)
- Bioavailability: Enhanced compared to RAD 140
- Status: Research chemical, not FDA approved
How Does RAD 150 Work?
RAD 150 works by selectively binding to androgen receptors in skeletal muscle and bone tissue, promoting anabolic activity without the widespread effects associated with traditional anabolic compounds.
The mechanism involves several steps:
- Absorption: RAD 150 enters the bloodstream where the benzoate ester provides enhanced stability
- Selective Binding: The compound preferentially binds to androgen receptors in muscle and bone tissue
- Anabolic Signaling: Once bound, it may trigger anabolic signaling pathways that promote muscle protein synthesis
- Extended Release: The ester modification allows for slower, more consistent release compared to RAD 140
Unlike traditional anabolic compounds that affect multiple tissues throughout the body, SARMs like RAD 150 are designed to be tissue-selective. This selectivity is what researchers find most interesting about this class of compounds.
The extended half-life means the compound remains active in the system longer, potentially requiring less frequent dosing. However, this also means it takes longer to clear the system entirely.
RAD 150 Benefits: What Research Suggests
Based on available research and user reports, RAD 150 may offer several potential benefits. It is important to note that human clinical trials are limited, and most information comes from preclinical studies and anecdotal reports.
1. May Support Lean Muscle Development
Preclinical research suggests RAD 150 may support lean muscle mass development through its selective binding to androgen receptors in skeletal muscle.
Users on Reddit have reported noticeable changes in muscle fullness and strength during research cycles.
2. Potentially Enhanced Recovery
One Reddit user shared: “Recovery was really good, could train more frequently than before.”
The compound may help reduce recovery time between training sessions, allowing for more consistent training schedules according to user reports.
3. Extended Half-Life Advantage
The longer half-life compared to RAD 140 may provide more stable blood levels. This could translate to more consistent effects and potentially simpler dosing schedules.
4. May Support Strength Gains
User reports suggest strength improvements during RAD 150 research cycles. One Reddit user reported their bench press increased from 90kg to 100kg during their cycle.
5. Potential Body Composition Benefits
Some users report improvements in body composition, including potential fat loss alongside muscle development. However, diet and training remain primary factors.
6. Research Applications
Scientists are investigating RAD 150 for potential applications in muscle wasting conditions, osteoporosis research, and hormone therapy alternatives. These applications remain in early research stages.
Important: RAD 150 is sold strictly for research purposes. It is not approved for human consumption by the FDA or any regulatory body. All benefits mentioned are based on preclinical research and anecdotal reports.
RAD 150 vs RAD 140: Key Differences
RAD 150 is essentially an esterified version of RAD 140, but the modification creates several important differences. Based on research and user reports, here is how they compare.
| Feature | RAD 150 (TLB 150) | RAD 140 (Testolone) |
|---|---|---|
| Half-Life | 48-60 hours (estimated) | 16-20 hours |
| Dosing Frequency | Once daily or every other day | Once daily |
| Bioavailability | Enhanced | Standard |
| Chemical Stability | Higher (esterified) | Standard |
| Research History | Newer compound | More established |
| Typical Research Dosage | 5-10mg daily | 10-20mg daily |
| Price (30ml) | $40-80 | $40-70 |
Liver Toxicity Comparison
One concern that frequently comes up in forums is liver toxicity. According to user discussions on Reddit, oral RAD 150 may have more liver impact than RAD 140.
One user noted: “Injectable RAD has super low liver impact, but oral RAD 150 has more liver toxicity than 140.”
Researchers studying these compounds typically recommend liver support supplements like TUDCA during cycles. Blood work before and after cycles is considered best practice in the research community.
Which Is Stronger?
This is a common question with no definitive answer. RAD 150 may feel “stronger” due to its enhanced bioavailability and longer half-life, which can result in more consistent blood levels.
However, RAD 140 has more research behind it and a longer track record in the SARM community. The choice often comes down to personal research goals and how the body responds to each compound.
RAD 150 Dosage and Cycle Length
Standard research dosages for RAD 150 typically range from 5-10mg per day based on community discussions. Due to its longer half-life, some researchers dose every other day instead of daily.
| Experience Level | Suggested Dosage | Cycle Length | Notes |
|---|---|---|---|
| Beginner | 5mg daily | 6-8 weeks | Start low to assess tolerance |
| Intermediate | 7.5-10mg daily | 8 weeks | Standard research dose |
| Advanced | 10-15mg daily | 8-10 weeks | Higher suppression risk |
Cycle Length Considerations
Most researchers run RAD 150 cycles for 8 weeks. Extending beyond this may increase the risk of hormonal suppression and other side effects.
The longer half-life means the compound stays in your system longer after discontinuation. Allow adequate time for clearance before any blood work or testing.
PCT (Post Cycle Therapy) Requirements
RAD 150 is suppressive of natural testosterone production. PCT is widely recommended in the research community even for shorter cycles.
Common PCT protocols include:
- Nolvadex (Tamoxifen): 20mg daily for 4 weeks
- Clomid (Clomiphene): 25-50mg daily for 4 weeks
- Enclo (Enclomiphene): 12.5-25mg daily for 4 weeks
Blood work before and after cycles is the only way to accurately assess hormonal recovery. Do not skip PCT based on how you feel.
Pro Tip: Get baseline blood work before starting any research cycle. This gives you a reference point for recovery and helps identify any pre-existing issues.
RAD 150 Side Effects and Safety
Like all SARMs, RAD 150 carries potential side effects. Based on user reports and available research, here are the most commonly reported issues.
Common Side Effects
- Testosterone Suppression: The most significant concern. Most users experience some degree of hormonal suppression
- Sleep Disturbances: Users report insomnia or disrupted sleep, especially in the first week
- Headaches: Mild to moderate headaches, usually temporary
- Mood Changes: Some users report irritability or mood swings
- Increased Libido: Can be excessive for some users, one Reddit user cut their cycle early due to this
Liver Considerations
Oral RAD 150 may have hepatotoxic potential. Reddit discussions suggest it may be more taxing on the liver than RAD 140 when taken orally.
Liver support supplements like TUDCA (250-500mg daily) and NAC are commonly recommended during cycles. Avoid alcohol and other hepatotoxic substances.
Sleep Issues and Solutions
Sleep disturbance is a frequently reported side effect, particularly in the first few days. One Reddit user shared their experience: “Sleep was disturbed first few days but resolved with MK677 addition.”
Some researchers stack MK-677 (Ibutamoren) to counteract sleep issues, as it may improve sleep quality. However, this adds another compound to the research protocol.
Safety Recommendations
- Blood Work: Get comprehensive blood panels before, during (optional), and after cycles
- Start Low: Begin with the lowest effective dose
- Liver Support: Use TUDCA or NAC during the cycle
- Time Off: Allow adequate time between cycles for full recovery
- Quality Products: Only use third-party tested products from reputable vendors

Typical protocol: RAD 150 5-10mg + MK-677 10-25mg daily
RAD 150 + Cardarine (GW501516)
Cardarine is often added for endurance enhancement and potential fat loss support. It is not a SARM but a PPAR agonist.
Typical protocol: RAD 150 5-10mg + Cardarine 10-20mg daily
RAD 150 + LGD-4033 (Ligandrol)
This combination is discussed for maximum muscle-building research. However, stacking two suppressive SARMs increases hormonal impact.
Typical protocol: RAD 150 5mg + LGD-4033 5mg daily (reduced doses due to stacking)
Caution: Stacking compounds increases complexity and potential risks. More compounds mean more variables and greater suppression potential. Blood work becomes even more critical when stacking.
