Product Description

RAD140 Testolone is one of the most potent SARMs available, designed to provide anabolic benefits similar to testosterone without the unwanted side effects. It selectively targets androgen receptors in muscle and bone tissue, promoting lean muscle growth and strength enhancement.

Our pharmaceutical-grade RAD140 is produced under strict quality controls and third-party tested for maximum purity. Each capsule delivers 10mg of pure Testolone for consistent, powerful results

What Makes RAD-140 Effective for Recomposition?

RAD-140 (Testolone) is the go-to SARM for users seeking serious muscle gains without the side-effect profile of traditional androgens.

Whether you are bulking, recomping, or looking to break through a strength plateau, RAD-140 delivers results that few compounds can match at equivalent doses.

What makes RAD-140 particularly effective for recomposition is its dual action on muscle and bone tissue. By selectively binding to androgen receptors in these tissues, it promotes anabolic activity where it matters most. Users consistently report a harder, drier physique alongside measurable increases in strength.

Preclinical data in rats and non-human primates confirmed strong anabolic signalling in muscle and bone tissue with significantly reduced androgenic activity in the prostate. [1]

  1. Devin Lexis –

    Wanted to try RAD-140, started with 5mg just to warm up. After the second week bumped it up to 10mg and honestly the jump was really noticeable. On the first thought its only 5mg, but I could feel that after the add on my muscles looked fuller and more pumped up after workouts. And the best thing that I look a lot better with almost the same number on the scale as before the cycle. Its really good, I would 100% take it again, but for those who are reading this and want to try it for the first time – its not that mild as it seems.

  2. Jeffrey Roberts –

    Went from 65kg bench to 84kg in just 5 weeks.

  3. Jacob Phillips –

    Had bit of acne, but after 3 to 4 weeks it was gone and didn’t have any other problems.

  12. Frank Bailey –

  13. Scott Morris J. –

    Lol got so big just by two cycles, that my mom ask if am taking something lol

  14. Jose Torres –

    Since the cycle I look much bigger

  15. Bob P. –

    Ran RAD-140 10mg for the whole cycle. When the second week roled around the results where honestly amazing. No side effects at all, weights where flying up and down like never before. Finally look good in the mirror. For me 10mg where definitely the sweet spot, but for the next cycle I would consider maybe 15mg or even 20mg but overall pure and amazing product.

  16. Larry Stewart –

    Interestingly enough, I didn’t experience any side effects :()

  32. Leon Sanders –

    Tried RAD-140 for the first time, didnt really know what to expect. Everyone told me that it would suppress me, so I took the advised dosage of 10mg just to be saf. On the first week everything was smoth no big changes. Around the second week started feeling some strength boosts and looked fuller. As I finished the cycle, I didnt notice any suppression or sides. 10/10 would recommend.

How Does RAD140 (Testolone) Work?

RAD140 Testolone works by selectively binding to androgen receptors in muscle and bone tissue, avoiding interactions with other organs that could cause unwanted side effects. This selective action promotes anabolic activity in the target tissues.

The compound has a high affinity for androgen receptors and demonstrates tissue-selective activity, making it highly effective for building lean muscle mass while supporting bone health. Its unique molecular structure allows for oral bioavailability with a half-life of 15-20 hours.

Users typically experience significant strength gains within the first week, with visible muscle growth becoming apparent after 2-3 weeks of consistent use.

Key Actions

1 Binds selectively to androgen receptors
2 Promotes muscle protein synthesis
3 Enhances strength and power output

Stacking and Cycle Guidance

RAD-140 fits into a range of protocols depending on your research focus:

  • Bulking: Stack with LGD-4033 for compounded lean mass gains.
  • Recomposition: Stack with Cardarine GW-501516 to add a fat oxidation component alongside muscle building.
  • Cutting: RAD-140 alone is sufficient to preserve muscle tissue through a caloric deficit.

Dosing typically ranges from 10 to 15mg daily, with most users finding the 10mg capsule sufficient for significant results. Cycle lengths of 8 to 10 weeks are standard, followed by an appropriate break. Given RAD-140’s potency relative to other SARMs, a PCT protocol should be considered following longer or higher-dose cycles.

RAD-140 and Neuroprotection

Beyond muscle and bone, RAD-140 has attracted research interest due to its potential neuroprotective effects.

A 2014 study published in Endocrinology found that RAD-140 was as effective as testosterone in reducing hippocampal neuronal death induced by apoptotic insults in vitro and demonstrated neuroprotective effects in vivo in a rat excitotoxicity model. [2] The authors described the findings as relevant to Alzheimer’s disease research. Human data are not yet available for this application.

WADA prohibits RAD-140 under the category of anabolic agents. Sold by CORE SARMS strictly for research purposes. All batches are third-party tested and supplied with a certificate of analysis.

Frequently Asked Questions

RAD140 is a selective androgen receptor modulator (SARM) that promotes lean muscle growth and strength gains with minimal side effects.

Most users report strength gains within 1-2 weeks, with visible muscle growth typically appearing after 3-4 weeks of consistent use.

Some users may experience testosterone suppression, mild fatigue, or mood changes. Side effects are typically temporary and vary depending on dosage and cycle length.

Yes, RAD140 can be safely stacked with other SARMs or supplements. Consult our stacking guide for optimal combinations.

CORE SARMS RAD140 is pharmaceutical-grade, third-party tested, and manufactured in certified facilities for maximum purity and potency.

RAD-140 has a half-life of approximately 15-20 hours, meaning it stays active in the body for about 24-36 hours. This makes it suitable for once-daily dosing.

RAD-140 can be taken any time of day, but it’s best to take it at the same time daily for consistency. Many users prefer morning doses to align with training schedules and energy levels.

Preliminary studies suggest RAD-140 may have neuroprotective properties, helping support brain cell health. However, more research is needed to confirm these effects in humans.

RAD-140 does not aromatize into estrogen, so the risk of gynecomastia (gyno) is extremely low. However, improper stacking or high-dose cycles may indirectly affect hormone balance in some users.

No, RAD-140 does not convert into DHT (dihydrotestosterone). It selectively binds to androgen receptors in muscle and bone tissue, avoiding most of the side effects associated with DHT-related compounds.
