Product details
Buy RAD 140 UK: CORE supplies RAD 140 (Testolone) in the UK as 60 x 10mg capsules, third-party lab tested, with the certificate included. RAD 140 is designed to provide anabolic benefits similar to testosterone, with a more selective profile. 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 a popular choice for users seeking muscle gains with a more selective profile than 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]

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
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.

How to Use RAD 140 (Testolone)?
Dosage
10mg once daily
Timing
Take with breakfast for optimal absorption
Cycle Length
6-8 weeks followed by a 4-week break
Important
Dietary supplement use only
Take with food to improve absorption. Start with lower dose if new to SARMs.
Training
Stick to heavy compound lifts and prioritize intensity over volume or longer sessions.
Diet
Eat at a surplus of 300–500 calories. Keep protein high and limit saturated fats to protect your cholesterol.
Stacking and cycle guidance
RAD-140 fits into a range of protocols depending on your research focus. Pick a single companion below to stack with RAD-140 and save 5%, or choose a complete bundle further down for a bigger discount:
Ligandrol (LGD 4033) + RAD 140 (Testolone)
Bulking: LGD-4033 piles on mass RAD-140 can't reach alone.
£90.25 £95.00 Save 5%
LGD-4033 5-10mg + RAD-140 5-15mg, both once daily each morning. Run together for 6-8 weeks. PCT required after.
Ligandrol dosage and cycle guide
Cardarine (GW501516) + RAD 140 (Testolone)
Recomposition: Cardarine burns fat while RAD-140 builds muscle, hitting recomp from both sides.
£95.00 £100.00 Save 5%
Cardarine 5-10mg, 1-2 hours before training. RAD-140 5-15mg each morning. Cardarine can run a little longer if needed. PCT still required for the RAD-140 portion.
MK 677 (Ibutamoren) + RAD 140 (Testolone)
Recovery: MK-677 lifts GH and IGF-1 output so a strength-focused cycle recovers faster.
£93.10 £98.00 Save 5%
MK-677 10-25mg, 30-60 minutes before bed. RAD-140 5-15mg each morning. Run together for 8-12 weeks. PCT still required for the RAD-140 portion.
MK 677 side effects, benefits and dosage guide
YK11 (Myostatin) + RAD 140 (Testolone)
Advanced: YK-11 adds a second growth pathway, built for lifters who've outgrown a standard cycle.
£99.75 £105.00 Save 5%
YK-11 5-10mg + RAD-140 5-15mg, both once daily. Keep this stack to 6-8 weeks given the combined intensity. PCT required after.

Frequently Asked Questions
Contact supportRAD 140 is a selective androgen receptor modulator that promotes lean muscle growth and strength gains.
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.
You can buy RAD 140 UK directly from CORE. Each bottle holds 60 x 10mg RAD 140 (Testolone) capsules, a 2-month supply at 1 capsule daily, with a third-party lab certificate included. UK orders typically arrive in 3-7 business days.
