High Purity MK677 and RAD140 – Double Compound Formula
MK677 and RAD140 product combines 2 widely referenced investigational compounds into a single, clearly dosed capsule format:
• 10mg MK-677 (Ibutamoren)
• 10mg RAD-140 (Testolone)
Compound Overview
This product brings together 2 compounds that act through different biological mechanisms:
MK-677 (Ibutamoren)
has been widely studied for how it influences growth hormone signalling within the body. In controlled settings, it has been examined for its ability to:
- Increase measurable growth hormone (GH) and IGF-1 levels
- Support lean tissue development pathways
- Support fat metabolism signalling
- Support recovery-related hormonal activity
- Promote collagen-associated processes linked to skin and connective tissues
- Associated with better sleep quality in research settings
- Studied as an oral option instead of injectable GH
- Studied in relation to age-related hormone decline
RAD-140 (Testolone)
RAD-140 appears in pre-clinical and mechanistic studies and has been examined for its ability to:
- Bind selectively to androgen receptors in muscle tissue
- Support lean tissue development pathways
- Support strength-related cellular signalling
- Support muscle retention mechanisms during calorie-controlled conditions
- Support bone-associated signalling pathways
- Promote anabolic signalling without conversion to oestrogen
Research examines RAD-140 to better understand receptor-mediated signalling pathways distinct from anabolic steroids.
Each of the 2 compounds operates through a separate receptor system, which is one reason they are often discussed together in scientific literature.
Mechanism Summary
• A compound examined for growth hormone pathway signalling
• A compound studied for selective androgen receptor interaction
Because these mechanisms differ, they are frequently analysed together when examining muscle-related and endocrine signalling systems in controlled environments.
Published scientific literature discussing MK-677, RAD-140 and related signalling mechanisms can be accessed via the PubMed database.

I’ve really liked taking this product so far. The additional recovery and strength boost it delivers is on another level but can you please look into accepting PayPal or Apple Pay?
February 11, 2026
Love this combo, been using this for a while, amazing gains, always super helpful and always delivered quickly 👍👍
January 22, 2026
I would highly recommend this product and Affordable Nutrition to anyone interested in smashing through platueaus. They provide an excellent service at very competitive rates. Thanks to all concerned
January 5, 2026
Amazing how this can pack on size when you’re well fed on a bulk lol. The pumps and recovery both boost strength it’s like an upwards spiral 💪
December 1, 2025
I definitely have increased muscle mass and I’ll never get tired of the pumps lol but its the motivation and general positivity that surprised me the most. I researched 2 caps ED for 60 days and felt the hunger in the first couple of weeks but thankfully that seemed to settle down and all in all was easy enough to live with. I’m in no rush but I’ll definitely consider a repeat cycle some time in the new year/early spring
November 12, 2025
Super stack from Affordable Nutrition. Very happy with the research results. After 3 weeks you feel unstoppable, then its up to you how much you want to gain with hard work and plenty of nutrition can 100% recommend!
October 20, 2025
Super product, clear communication, lightning delivery, can’t want for more!
October 6, 2025
Excellent results every time. Staff extremely helpful. Would definitely recommend and will be returning customer
September 11, 2025
Loving this, the motivation and energy’s taking me back years to when I first started out 💪🏽
August 13, 2025
Ordered this for the first time and received excellent customer service, arrived the next day with no problems. You get the boost in energy and motivation before the strength and muscle gains – 5 ⭐⭐⭐⭐⭐
July 27, 2025
Awesome gains!! Like being back on tackle after 3 weeks 🤣
July 21, 2025
Used this to bulk for 2 months and results were great. Recovery between sessions improved almost immediately, same with the muscle pumps. The weight and strength came on more and more as the cycle progressed. No sides to mention, maybe a bit of tiredness towards the end but by that time I was putting considerably more effort in too
July 1, 2025
I’m a full week in now, sleep has been incredible and I’ve got an extra boost of motivation too
June 16, 2025
Done 30 days and so far so good. Just need to lose more fat now.
June 9, 2025
Excellent product and very good service
May 27, 2025
Perfect for packing size and strength on if you’re stuck in a rut like I was. No side effects to date (after 30 days researching) and noticeable increase in motivation and wellbeing
May 12, 2025
After 2 weeks im really happy seeing noticeable changes already. Fast and freindly service happy to help out. Will be recommending for sure
April 25, 2025
Perfect combination seeing lots of progress 💪
April 14, 2025
After a week my energy levels and muscle pumps are increasing already. Getting that love back for the game!!!
April 8, 2025
I’ve been using this combo for about 8 weeks now, and the results have been impressive. My strength has gone up significantly, and I’ve noticed a good amount of muscle gain without any crazy side effects. The increased appetite from MK-677 was a bit much at first but I just used it to eat more lol. Sleep, mood and recovery have all been boosted, the only downside is a little bit of water retention, but nothing major and to be expected on a bulk anyway
March 18, 2025
I’ve just completed my first ever cycle and I don’t normally leave reviews but the strength increases from starting point to finish have been fricken insane!!
February 26, 2025
Having tried the mk-677 thought I’d give this a go and put on a solid stone after 60 days of research. Big boost to motivation and drive, never recovered as fast as this, felt great tbh
January 23, 2025
Brilliant product. Great service. Quick delivery time.
December 7, 2024
Great product, decided to purchase again as my previous results where remarkable. Ships promptly.
October 12, 2024
I've completed my first cycle and would say it takes a couple weeks to notice results. Better sleep, strength, confidence and better weight gains, and strength of course. I would highly recommend researching with this stack 💪
September 14, 2024
Really happy with the results from my "research" best I’ve ever looked and felt can recommend!
August 11, 2024
Amazing service and advice from these guys. Answered all of my questions quickly and professionally. Legit product for sure, recovery is on another level. Makes you want to push harder when you get these pumps lol
July 22, 2024
Just started the second bottle, it took about 2 weeks to notice anything other than pumps but after I hit the 3 week mark strength gains began to show. I've upped the protein intake a fair bit as well, recovery on my sessions is faster now so as to train each muscle group more than one time a week to get the most from it. I'm not suffering from DOMS but just a tiredness in the muscle the next day so its definitely working
July 5, 2024
This is a brilliant product for improving sleep and recovery, far less aches and pains. Size is steadily coming on lean and dry, pumps are proper solid! Getting fantastic mental results too. Loving life and feeling motivated, almost worth it for that alone!!
June 14, 2024
Ive seen great results even though ive actually been cutting for the past 8 weeks but ive still made great gains and reduced my body fat.
May 23, 2024
Cycle has gone really well actually supprised at how much bigger I am.
May 5, 2024
What a sleep am getting and good recovery gains. All numbers are up so very happy 💪💪💪
April 24, 2024
So far had some good gains and strength increase has been incredible can't fault it. Also felt so good since taking it. So will definetly be doing a second cycle
April 2, 2024
After 5 days I'm already sleeping better and getting some mad pumps! I can only imagine it will get even better
March 23, 2024
My favorite 2 products!!!
March 5, 2024
I’m 3 weeks into this combo course and I thought Id leave an update. I’m in a lot better place mentally, experienced no side effects whatsoever, I’m sleeping better and my appetite has increased. I’ve seen a small strength increase but it’s the mass increase that’s astounding. I just can’t believe how much muscle I’ve gained in 3 weeks.
February 14, 2024
Very happy with how the cycle went well, put on an additional 8KG in 10 weeks! Plus I’ve been able to break my plateau on my bench going from 80KG to 90KG for reps. Can't wait to get onto the next cycle after the PCT.
February 7, 2024
3 weeks in to an 8 week cycle and i’m already seeing changes in my vascularity and i look super dry, the mk677 is also great for sleep and recovery.
February 1, 2024
So pleased with the results from 60 days research. My rat never puts on any weight but has added 4kg of really lean muscle 🙂
January 28, 2024
Bought here as titan-chem didn't have any rad140 left and they suggested I try here.
Good service and a good product.
January 4, 2024
Top, top product. Everything I expected it to be. Energy levels, strength, and I look much much dryer
November 18, 2023
Normally not one for leaving reviews, but this stuff deserves a shoutout. Tried one bottle, didn’t know what to expect. But I noticed after 2 weeks I’m recovering quicker with hardly any of the usual aches and soreness. Huge win for me since I’m a joiner on site. Kept my diet mostly the same (just cleaned it up a tad and added a pre-bed shake). Seeing solid gains, especially in the shoulder department. Oh and major props for the fast delivery — ordered on a Friday, got it on Saturday for 1.95, worth a mention in itself. Great job guys!!!
October 24, 2023
Halfway through a 60 day cycle and feel great. Seeing improvements almost daily now with zero sides. Fantastic stack!
September 14, 2023
Great Product
September 11, 2023
I don’t know what this stack is like for bulking but it was like dialling back the clock 10+ years for a recent recomp. Highly recommend
August 8, 2023
I've completed a 90 day research cycle of this product. I would say it takes a couple weeks to notice results. Better sleep, strength, confidence and lean weight gains. I would highly recommend using this product for your research.
July 10, 2023
Very effective stack at a great price with super fast delivery
June 16, 2023
Awesome!!
May 22, 2023
Good product and nice saving
April 20, 2023
Fantastic product 10/10!
March 23, 2023
Purchased many times good gains and always super fast delivery
March 2, 2023
I bought this with the standard MK 677 as I wanted to “research” 30mg of MK 677 but with 20mg of RAD 140. The MK 677 has made a big difference to my sleep and a troublesome left shoulder and the RAD 140 has providing the boost I wanted for putting some muscle on. Can see the difference in 3 weeks and feel great!
February 11, 2023
As a long time user I highly rate this product. Delivery is always fast and hassle free
February 3, 2023
Awesome product!
January 12, 2023
These guys do the best MK 677 on the market and with the RAD 140 is genius. The owner is a very knowledgeable guy and delivery is always super fast.
