Introduction
RAD-140, also known as Testolone, is one of the most widely studied SARMs due to its potential for muscle growth and strength. One of the most common questions researchers and enthusiasts ask is simple: “Is it better to take RAD-140 before or after a workout?”
While RAD-140 isn’t like a pre-workout supplement that delivers immediate effects, timing still matters when it comes to consistency, blood levels, and how researchers might structure a study. Let’s break it down.
How RAD-140 Works (Quick Recap)
RAD-140 is a selective androgen receptor modulator (SARM). Unlike anabolic steroids, which activate androgen receptors throughout the body, RAD-140 is designed to selectively target receptors in muscle and bone tissue.
Because of this mechanism, RAD-140’s effects are not instant like caffeine or nitric oxide boosters. Instead, its benefits come from maintaining stable levels over time.
Before vs After Workout: What Research Suggests
- Taking RAD-140 Before a Workout
Some researchers argue that taking RAD-140 before training could be beneficial, under the logic that:
It might align peak blood levels closer to the training session.
For those studying endurance or strength output, this timing may feel more intuitive.
It creates a daily routine tied to training, which can help with adherence.
However, since RAD-140 does not work as an acute stimulant, the performance benefit from taking it immediately pre-workout is limited. Its effectiveness comes from consistent receptor activation, not timing around exercise.
- Taking RAD-140 After a Workout
Others prefer post-workout administration, reasoning that:
Training depletes the body, and post-workout is when anabolic signalling and recovery processes are most active.
In research settings, pairing RAD-140 administration with recovery might theoretically enhance protein synthesis.
It also creates an easy-to-remember schedule for those who train at the same time each day.
While this logic makes sense, research does not conclusively show a superior effect for post-training dosing either.
The Bigger Picture: Consistency Over Timing
Ultimately, the research consensus is clear: it doesn’t matter whether RAD-140 is taken before or after a workout — what matters is consistent daily administration.
RAD-140 has a relatively long half-life (often reported as 20+ hours), meaning it stays active in the body throughout the day.
Because of this, maintaining steady blood levels is more important than the exact timing of administration.
Whether morning, pre-workout, or evening, the results in research largely depend on dose consistency and duration of study, not timing.
Practical Considerations in Research
Choose a time you won’t forget: Many researchers recommend taking RAD-140 at the same time every day. This creates a consistent habit and keeps blood levels steady.
Split dosing isn’t necessary: Given its long half-life, most studies observe that a single daily dose is sufficient. There’s no strong evidence suggesting multiple doses per day improve outcomes.
Linking it to your training schedule: If linking RAD-140 administration to your workout (before or after) helps ensure consistency, then either option works fine.
Does Timing Affect Side Effects?
Some anecdotal reports suggest that RAD-140 may cause mild sleep disturbances in sensitive individuals. For those, taking RAD-140 earlier in the day — whether pre- or post-workout — may be preferable to night-time use.
Beyond this, side effect profiles don’t seem to change based on whether it’s taken before or after training.

How RAD-140 Compares to Pre-Workout Compounds
It’s important to highlight that RAD-140 is not a stimulant. Unlike caffeine or beta-alanine, which provide short-lived boosts in energy or focus, RAD-140 works by gradually enhancing muscle growth, strength, and recovery through consistent androgen receptor activation.
So, while the question of pre- vs post-workout timing is common, the more relevant factor is long-term use in research, not acute performance effects.
Stacking Considerations in Research
Sometimes RAD-140 is studied in combination with other compounds, and timing may play a more meaningful role in those cases:
MK-677 (Ibutamoren): Often taken at night to support sleep and growth hormone release.
Cardarine (GW-501516): Sometimes used pre-training in endurance-focused studies, since its effects are more directly tied to energy metabolism.
Enclomiphene: Researched in PCT settings after RAD-140, where timing is linked to recovery rather than workouts.
In these contexts, RAD-140’s flexible timing makes it easy to fit into broader research protocols.
Conclusion
So, should you take RAD-140 before or after a workout? The evidence suggests it doesn’t matter.
What matters most is:
Taking it consistently at the same time each day.
Ensuring dosing aligns with research protocols.
Monitoring outcomes over weeks and months, not hours.
If linking RAD-140 to your workout routine makes it easier to remember, then either pre- or post-training works equally well. For researchers, consistency — not timing — is the real key to results.
