The duration of RAD140 (Testolone) in the body can be understood in three key ways: its half-life, how long its effects last, and how long it remains detectable on a drug test.
Here's a breakdown of each:
| Aspect | Duration | Details |
|---|---|---|
| Elimination Half-Life | ~45 to 60 hours | This is the time it takes for your body to eliminate half of the dose. A half-life of ~45-60 hours means the drug stays in your system for a relatively long time, supporting once-daily dosing. |
| Detection Time | Up to 29 days | This is how long the drug or its metabolites can be found in a urine test after a single dose. Even with micro-doses, RAD140 can be detected for weeks. |
| Duration of Action | Effect lasts for days | Due to its long half-life, the anabolic (muscle-building) effects are not immediate and build up over time with consistent daily use. |
📝 Important Details & Context
Half-Life Stability: The ~45-60 hour half-life is the key figure for humans. This is supported by a Phase 1 clinical study which reported a half-life of 44.7 hours.
Accumulation: Because of its long half-life, RAD140 will accumulate in your body if taken daily. One study showed that after five days of daily dosing, the concentration in the body was 2.4 times higher than after a single dose.
Dosing: For medical contexts, RAD140 is taken orally (by mouth) once daily.
