Overview: What Is RAD-140 (Testolone)?

RAD-140 is a non-steroidal agent designed to engage androgen receptors in target tissues preferentially. In preclinical settings, RAD-140 has been explored for effects related to anabolic activity in muscle and bone, with a pharmacology that is unlike anabolic steroids due to its tissue selectivity. Studies also examine potential neuroprotective effects through pathways associated with neuronal cell survival. Evidence in humans remains limited; ongoing research continues to evaluate safety, pharmacokinetics, and translational relevance.

Mechanism of Action: Androgen Receptors, Muscle and Bone

As a selective androgen receptor modulator, RAD-140 binds androgen receptors with high affinity in muscle cells and bone tissues. Downstream signaling in preclinical models has included increases in protein synthesis, support of lean muscle mass and muscle fiber hypertrophy, and markers relevant to bone density. Because of its selectivity for target tissues, RAD-140 is frequently contrasted with anabolic steroids that may influence a broader range of other tissues. Its tissue selectivity profile and receptor pharmacodynamics remain active areas of investigation.

In vitro and animal models have reported:

• Changes in markers related to muscle protein synthesis and lean tissue mass
• Modulation of genes associated with lipid and energy metabolism
• Neuroprotective signaling in neuronal cultures
• Receptor activity suggesting tissue selectivity relative to anabolic steroids

Note: These findings are preliminary and not demonstrated in human studies.

However, it is essential to note that the Food and Drug Administration (FDA) has not confirmed any health effects of RAD-140 in humans or approved it for human use; therefore, the drug should be used in a laboratory setting.

High AR Binding Affinity of RAD-140

RAD-140 demonstrated excellent affinity for the AR (Ki = 7 nM), higher even than DHT and most anabolic steroids. For reference, the affinity for the androgen receptor (AR) for testosterone in a recent preclinical model was 29 nM, and 10 nM for DHT.

Unlike testosterone and most other AR-mediated anabolic agents, Testolone is orally bioavailable, so it does not require injection for proper absorption, and it is considered by many researchers to be one of the best SARMs for bulking and adding lean body mass.

Testolone is a relatively recent addition to the list of SARMs for sale; it was developed in 2010 as a possible treatment for osteoporosis and muscle gains. More recent testing performed on rats and primates, as well as clinical trials, has indicated that it may provide additional benefits.

Research Applications (Preclinical and Early Clinical Context)

• Muscle biology: Studies exploring pathways linked to lean muscle growth, hypertrophy, and anabolic signaling in skeletal muscle.
• Bone health: Investigation of androgen-receptor–mediated effects on bone turnover and potential support of bone density.
• Neuroprotection: Evaluation of cell survival signaling and anti-apoptotic markers in neuronal models, with preclinical reports of neuroprotective effects.
• Oncology research: Assessment in select hormone-receptor–positive cancer models for anti-proliferative activity.

Side Effects of RAD-140

While RAD-140 and other SARMs do not cause androgenic side effects to the same extent as anabolic steroids like testosterone, reports have revealed the potential for nausea, aggression, reduction in natural testosterone levels, or mild male pattern hair loss from the use of RAD-140. A single-member case report indicated drug-induced liver injury after 11 months of the use of an antidepressant, as well as intermittent use of RAD-140 and LGD-4033.

The limitations of this study, however, are that it includes only one test subject, 11 months of concurrent antidepressant use, the quality and quantity of SARMs used by the subject were not monitored, and additional comorbidities were not investigated.

Several case reports exist indicating the potential for selective androgen receptor modulators to contribute to liver injury but none involve a significant sample size or test controls to date. Like other SARMs, RAD-140 may trigger a negative feedback loop and a reduction in natural testosterone production and testicle size though further research is needed to determine the likelihood and severity of this occurrence.

RAD-140 and Muscle Growth

A study on young male cynomolgus monkeys investigated the anabolic effects of 28 days of RAD-140 at a dosage of 0.01mg/kg, 0.1mg/kg, and 1mg/kg per day. A mean weight gain of 10% was observed in both the 0.1mg/kg/day group and the 1mg/kg/day group, indicating a quantity response curve that leveled off and provided no additional benefit with higher quantities.

There was no consistent effect on body fat mass in either group; however, muscle mass increased in the 0.1 and 1mg/kg/day groups. No significant increases in liver enzymes or prostate weight were reported in either group, suggesting a high level of selectivity for androgen receptors in muscle tissue.

RAD-140 and Neuroprotection

Androgens have shown clinical significance in preventing neuronal apoptosis and improving cognitive function in Alzheimer’s Disease (AD), primarily through a nongenomic mechanism of the Androgen Receptor (AR). Rapid phosphoinositide 3-kinase/Akt signaling, activated by androgens, regulates the expression of proteins linked to apoptosis such as Bax, Seladin 1, survivin, XIAP, and Bcl-xl.

Androgens can also maintain the integrity of neurons and thus improve cognitive function. Studies have shown that Aβ impairs the synaptic structure and function of hippocampal neurons, which is reversed by androgen administration, resulting in improved cognitive performance in AD animal models. Although the underlying exact mechanisms are not yet fully understood, androgen’s action of inhibiting Aβ-induced apoptosis appears to play a role.

RAD–140 and Cellular Protection

A 2014 study investigated the neuroprotective effects of RAD-140 on cultured neurons and male rats that were lesioned with kainate. The experiment included two parts: one in vitro, involving cell cultures, and another in vivo, through animal testing.

Results from the in vitro study showed that RAD-140 was able to prevent cell death and restore mitochondrial membrane potential, indicating that it could offer neuroprotection much like testosterone and other androgens investigated for these effects.

The in vivo experiment tested the efficacy of RAD-140 on male rats with kainate-induced seizures and showed a significant reduction in seizure activity compared to controls.

RAD-140 and Dementia

Another study on rats found that RAD-140 had neuroprotective benefits of a kind that may prevent Alzheimer’s disease and similar disorders, and may be safer than conventional testosterone therapy The group treated with 3 mg/kg RAD-140 was able to replicate the same level of muscle tissue growth as the group treated with 1 mg/kg testosterone, with about half of the androgenic activity in the prostate.

RAD-140 and Breast Cancer

A 2017 study investigated the effects of RAD-140 on breast cancer cells. The study evaluated the efficacy of RAD-140 in inhibiting the growth of breast cancer cells that were positive for both androgen receptors (ARs) and estrogen receptors (ERs).

Results showed that in in vivo and in vitro models of AR/ER+ breast cancer, RAD-140 was able to significantly reduce the growth and metastases of breast cancer cells without disrupting their cell cycle, indicating it could be a promising therapy for treating such cancers.

Moreover, the study also showed that RAD-140 had distinct mechanisms of action from those of anti-estrogens and aromatase inhibitors, which suggests that it could provide an additional therapeutic approach to treating hormone-sensitive breast cancers.

Overall, this study suggests that RAD-140 could be a potential option for AR/ER-positive breast cancer. Still, more data are needed to determine its safety relative to other methods currently used.
