RAD-140 (Testolone) – Research Compound Overview
RAD-140, commonly referred to as Testolone, is a selective androgen receptor modulator (SARM) that has been widely discussed in pre-clinical and clinical research literature for its high binding affinity and selectivity at the androgen receptor.
Within controlled laboratory environments, RAD-140 has been investigated as a tool for examining androgen receptor signalling pathways, tissue selectivity, and endocrine feedback mechanisms without the non-specific activity associated with traditional androgenic compounds.
This product is supplied strictly for analytical and laboratory research use, manufactured to high purity standards to support reproducible experimental investigation.
Although RAD-140 has appeared in human clinical research contexts, it is not approved for human use and remains strictly investigational.
Published research literature discussing RAD-140 can be accessed via the PubMed database.
RAD-140 in Research Context
In research settings, RAD-140 is characterised by its selective interaction with androgen receptors, allowing investigators to study downstream signalling pathways in a controlled and targeted manner.
Scientific literature has explored RAD-140 in relation to:
- Androgen receptor activation and selectivity
- Tissue-specific signalling models
- Comparative receptor affinity studies
- Endocrine feedback regulation
- Pre-clinical safety and tolerability parameters
These discussions are presented solely within experimental and research frameworks and do not imply application, usage, or outcomes.
Quality & Laboratory Standards
This RAD-140 research compound is:
- Produced under controlled manufacturing conditions
- Independently laboratory tested for analytical accuracy
- Supplied with batch-specific quality assurance data
- Intended to support consistency and reproducibility in research work
We prioritise transparency, analytical integrity, and quality control to ensure suitability for legitimate laboratory applications.
Research Combinations & Literature Context
Within scientific literature, RAD-140 is sometimes referenced alongside other investigational compounds when examining androgen signalling pathways, receptor selectivity, or comparative endocrine models.
These references are contextual only and do not imply usage, stacking, or consumption. All mentions reflect research discussion, not guidance.

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!!
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.

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 💪💪💪
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!

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
