High-Purity MK677 and MK2866 Capsules. Third-Party Verified for Quality
Our premium-grade MK677 and MK2866 capsules have undergone independent laboratory testing, revealing exceptional purity levels of 99.54% and 99.84% respectively. Certificates of Analysis are available in the Data Sheet section for full transparency and peace of mind.
Each capsule delivers a synergistic combination of 10mg MK677 and MK2866 10mg, designed for advanced research applications. Together, these compounds support a broad range of physiological enhancements, including:
Accelerated muscle growth and recovery
Enhanced fat metabolism
Stronger, denser bones
Improved cardiovascular and joint health
Optimised hormone balance and sleep quality
Why Combine MK677 and MK2866?
The combination of MK677 and MK2866 offers a powerful dual-action approach. MK677 is a potent growth hormone secretagogue that stimulates the natural release of GH (growth hormone) without suppressing your own endocrine system. This therefore leads to:
Faster lean muscle gain
Fat reduction and improved body composition
Better skin elasticity, hair quality, and nail strength
Deeper, more restorative sleep
Hormonal balance and reduced cortisol levels
In contrast to synthetic growth hormone (GH), which can cost upwards of £300 and often arrives degraded or fake, MK677 is cost-effective, orally stable, and clinically validated to deliver up to 6 IU-equivalent GH stimulation per day—without injections, refrigeration, or degradation risks.
Benefits of MK677 (Ibutamoren)
Promotes natural GH production without suppressing your own hormones
Also increases metabolic rate and supports long-term fat loss
In addition boosts collagen synthesis for healthier skin and joints
Similarly supports anti-aging, cognitive health, and enhanced sleep
Long half-life ensures sustained daily benefits with a single dose
However, unlike injectable synthetic GH, MK677 doesn’t damage your natural GH rhythm, making it ideal for long-term, consistent us. Not only that, no PCT required.
Advantages of MK2866 (Ostarine) – Targeted Anabolic Support
MK2866 is a selective androgen receptor modulator (SARM) that mimics the muscle-building effects of testosterone without the side effects of traditional anabolic steroids.
Key advantages:
Supports lean muscle gain with minimal water retention
Enhances strength, power, and endurance
Improves recovery time and reduces fatigue
Stimulates bone regeneration and reduces fracture risk
Promotes joint healing and in the same way reduces inflammation
Moreover, no significant estrogenic side effects and minimum testosterone suppression
Indeed, Ostarine’s tissue-selective action means it enhances muscle and bone without affecting other organs, making it a safer and more focused alternative to conventional steroids.
Why Choose Our MK677 and MK2866?
Dual-compound formula (10mg each per capsule) for synergistic benefits
Independently tested for purity and potency
Orally active – no injections required
Long shelf-life and stable at room temperature
Manufactured to high standards and free from contaminants
Real Research Results, Backed by Science
Moreover, emerging research and real-world results show that 20mg of MK677 daily may stimulate GH levels equivalent to 6 IU of synthetic HGH. Yet, MK677 avoids the pitfalls of injectables: instability, high cost, and suppression of natural hormone levels.
MK2866 on the other hand has been shown through research to help boost the immune system, making it easier to fight off infections and illnesses which can often grind progress to a halt.
Furthermore, MK2866 can help reduce inflammation and pain in the joints, making it easier to exercise and stay active. Just like muscle tissue, joints and connective tissues are broken down during intensive training, and can become inflamed, severely hampering performance and recovery.
MK2866 can also help improve bone density and reduce the risk of fractures and other bone–related injuries. This can be especially beneficial for athletes who are at risk of injury due to repeated impacts and intense physical activity.
Therefore this makes our MK677 and MK2866 capsules a smart, science-backed choice for those researching into serious performance enhancement without compromising health or safety.

I'm in week 4 of the cycle and my lifts have steadily progressed with no noticeable sides and much greater pumps. I'm aching less too so recovery is very much boosted. I recommend buying this as if you take 2 capsules per night, you'll 100% see the results in size and shape.

Coming to the end of my first ever cycle researching 2 tablets daily and thoroughly enjoying my workouts on them. Within a few weeks weights were flying up, I feel super focused and less fatigue during the day
September 9, 2025
I’ve been consistently cycling this stack for nearly 2 years now with no problems (run enclomiphene for PCT). The better sleep gives me more energy throughout the day and I’m recovering at 42 like I was 20 years ago. I’m still making gains albeit steady ones but I get to keep them and there’s no more daily fatigue and literally no side effects whatsoever
July 1, 2025
First time trying this out. It seems to do what it is intended to do
April 29, 2025
I’m really enjoying the product I’ve had a good bulk so far. Onto PCT for May hopefully will keep my gains before cutting in June
February 3, 2025
Made some decent gains and noticed some major improvements to my sleep and recovery. Overall solid and consistent progress with no crash at the end which tbh was the main reason I ditched prohormones to this type of “research.” PCT is still a must and yeah, you won’t make the same gains but its worth it in the long run and you’ll feel way better for it 💪🔥

All went well with no side-effects, improvements in strength and size and happy with the better nights sleep. Also arrived early, would recommend!

Happy customer here! Banging product and super fast delivery!!
March 6, 2024
Been taking this for just over three weeks and have already gained about 10lbs. Strength and pumps have noticeably improved too. Top top product!
November 23, 2023
Into my 3rd course after 2 courses of mk677. Now on a bulk and still unsure about the rad140 so decided to opt for this. can tell the difference for sure. I'm on extra calories so would expect to fill out but not this fast. Muscle pumps are through the roof to the point of being painful for biceps. No sides experienced and it appears to be coming on lean, so all things considered I think I've found my new go to bulking stack !!
September 26, 2023
Kept me swole on a cut. Zero crash and solid gains. Will purchase again
July 28, 2023
Awesome product for lean gains and boosted recovery! AN is the only place I'll shop for sarm stacks.
June 13, 2023
Great combo stack and delivery was super quick

Love this product works every time.
February 23, 2023
I’ve been researching with this product now for 4 weeks and the difference in my sleep, strength and recovery has exceeded expectations. My body weight is about the same which is fine as I’ve been running maintenance cals but the recomp is quick and just ordered another bottle. Very impressed with the service too arrived next day on the standard service!
January 6, 2023
Ordered again best value around and works every time. Sometimes get next day delivery on the standard service too. The owner of the business really knows what he’s talking about and is always happy to help.
December 7, 2022
Ease of order, payment and delivery speed all 5*. I won’t comment on the product itself as “research” hasn’t commenced. Previous research means I know what to expect and hopefully the product will be 5* as well.
Many thanks AN team
