99.63% Pure RAD-140 – Lab Verified | 60 x 12.5mg Capsules | Only £39.95
High-Purity RAD-140 (Testolone) Research Compound
RAD-140, commonly known as Testolone, is a non-steroidal Selective Androgen Receptor Modulator (SARM) developed as an investigational compound for research into androgen-receptor signalling.
Unlike testosterone and traditional steroidal androgens, RAD-140 has a non-steroidal chemical structure and was designed to investigate whether androgen-receptor activity could be influenced more selectively across different tissues.
This pharmacological profile has made RAD-140 an important compound in research examining androgen-receptor signalling, skeletal muscle biology, body composition and tissue selectivity.
Published research remains predominantly preclinical, although RAD-140 has also progressed into limited human clinical investigation.
Why RAD-140 Has Attracted Research Interest
RAD-140 has been studied because of its interaction with androgen receptors and its effects in experimental models involving skeletal muscle and other androgen-responsive tissues.
Research has examined areas including:
-
androgen-receptor binding and activation
-
skeletal muscle signalling
-
muscle fibre and lean-tissue research
-
body-composition markers
-
bone-related research
-
tissue-selective androgen activity

I feel more happy to train and seem to be making good progress with losing body fat and putting a bit of size on. Into my fifties so I keep cycles sensible and low dose but I always feel better on it so will continue as is for now.
September 25, 2026
Proper product this this, low dose worked just fine for me, managed to burn fat and building muscle at the same time on a high protein, moderate fat, low carb maintenance cals diet👌
August 26, 2026
Very good product for lean, dry gains. I noticed a clear improvement in strength and muscle definition without the water retention. Overall, I am very satisfied with the results and will use again
July 10, 2026
Overall I’m happy with this product and how my cycle went. Put on a good amount of size without the water retention. Did feel more aggressive at times but managed to channel that into some pretty awesome workouts. Sex drive also benefitted as has strength on all major compound lifts. Looking forward to a successful PCT which for products of this potency is just as important as the cycle itself

Defo legit rad felt brilliant like being back on test after a couple of weeks. Puts size on lean with good vascularity and no bloating can recommend
May 12, 2026
I started taking rad to help me in my workouts and recovery. It works for me, I notice the difference in my workouts and I do grow noticeably quicker. Also feel more motivated and driven, not sure if that’s placebo but I do feel better when taking it
April 18, 2026
great product speedily delivered
March 26, 2026
Cycle went really well, I had a long time off working out just before starting and I am way beyond where I began, way more motivated for the gym and much bigger while staying lean!
February 23, 2026
Good stuff for strength and recovery which kicks in within the first couple of weeks. Weight seemed to come on lean and consistently and no water retention or puffiness which is always a welcome bonus. Delivery is always spot on from here so overall can recommend
February 5, 2026
Slow start but a fast finish. Takes a short while to kick in but when it does it does! Shipping is fast, price is good and support is surprisingly helpful, can recommend
January 23, 2026
I bought a couple of pots of this, they arrived quickly and did what they said on the tin, will definitely use them again. I’m particularly pleased that despite being in a cutting phase since December, I’ve been super motivated and increased muscle mass while reducing body fat at the same time 💪👌
December 10, 2025
Pleased to say I’ve seen nearly 5kg weight increase in 8 weeks research without feeling bloated. I’d also say it’s helped mentally as made me a ton more motivated and not as anxious which was really good.
November 23, 2025
Super helpful staff and fast delivery .
October 15, 2025
Very much like the strength increases when this gets into your system. Makes you feel on top of the world with motivation and no water retention or bloating whatsoever. Clean product can recommend!! 💪
September 11, 2025
Excellent very good
August 24, 2025
Quality cycle results were great and support really does go above and beyond what I was expecting to receive back
June 19, 2025
Happy with this, kicks in after about 2 weeks and provides nice boost to strength and muscle hardness but I’m naturally quite lean anyway. No puffiness in my face or chest after 30 days and recovery is next level even with a few beers at the weekend 🍻😂🤦
May 13, 2025
Potent product for strength, clean and dry gains, can recommend
March 5, 2025
Had a 2 year lay off of sarms during a period my training has been very hit and miss. Back on these now and seeing and feeling changes pretty much on a weekly basis. Very good product backed up by a fair price and fast service
January 28, 2025
Good quality rad, sensibly priced and always delivered promptly
December 19, 2024
Excellent quality, needs a couple of weeks to build up, makes a real difference to strength and muscle hardness. Highly recommended
October 16, 2024
Can tell the difference between this rad and the old 10mg one. Delivery on point as always, won't be going anywhere else for my research 🙂
September 12, 2024
Good stuff from a good company! Well worth a try 💪💪💪
August 3, 2024
Takes a couple weeks to kick in but started feeling the mental benefits and better pumps after a few days. Much more motivated to stay on point with diet and positive to get stuff done and better focused in the gym. Now approaching the end of my 60 days research and my V taper has visibly improved with a little extra thickness in my delts. But the best thing is its helped me finally blast through a 4 month bench plateau!!
July 21, 2024
I'm really enjoying my mood on this rad140. There's solid strength progression happening on a weekly basis and I feel a lot more confidence and power going into the heavier/compound lifts. Delivery is reliable and support as always are a massive help too, can recommend!
June 25, 2024
I got a fair bit stronger and put on some decent size especially on my shoulders taking 2 of these a day.
May 21, 2024
Legit rad can recommend ordering from this supplier
April 11, 2024
Great booster for weights, can train harder for longer and I'm getting stronger and leaner at the same time. Had some questions that were answered quickly and in depth detail. Received the item the day after and have to say I'm very impressed with the product and the service
February 21, 2024
Approaching the end of my 1st 60 day cycle. Currently on a clean recomp since the New Year & put on 3KG to date but it looks a more tbh due to dropping bf most noticeably in my face, chest & shoulders. Strength has increased on practically everything, especially legs for some reason & no sides to report so far but I'm aware with progress like this I'll need to run a proper PCT protocol. Its my 1st time doing anything like this & I'd only recommend making the jump if everything else in place so you can take full advantage of the gains & protect your health!
January 8, 2024
Top quality rad, super impressed with speed of delivery
November 7, 2023
Fantastic product for recomping and muscle hardening. Always super fast delivery can recommend
September 13, 2023
best rad on the market and i've tried a lot over the years. never had a problem with this supplier
August 15, 2023
Put nearly a stone on in 12 weeks with size and strength improvements across the board. If you like rad you'll love this product! I also got some top advice from Affordable Nutrition for PCT. Excellent customer service, definitely got me as a customer going forward.

This Rad 140 with mk677 is a stack of stacks. 5 weeks in 12 pounds of lean muscle while reducing stomach fat also while comsuming 160g/180g a day protein. A few side effects from this stack, tingling in the hands from time to time and a few spots on chest. Cut of date is 7th July but will asses and may run it for another 4 weeks.
June 10, 2023
I’m 4 weeks in and very impressed with the results. Gained 5 pounds of lean muscle and lost some body fat. My strength and endurance have increased significantly. No side effects so far. I’ve just re-ordered and can honestly report this is the best sarm I’ve tried to date.
May 16, 2023
Great product for recomping. Highly recommend
May 2, 2023
Only a week in buy can see the increase in strength already and very happy with the super fast service!
April 19, 2023
Fantastic product would highly recommend and arrived quickly. Very helpful staff with quick responses to all questions.
April 14, 2023
Excellent product and gains are maintainable too. More fullness and vascularity but you need to run rad for 60 days as the last 3 weeks are a lot more impressive than the first 3 weeks
