What is Golden Stack?
Golden Stack is a precision-formulated SARM stack combining three of the most effective compounds in performance enhancement:
RAD-140 (Testolone)
MK-677 (Ibutamoren)
LGD-4033 (Ligandrol)
These three agents work synergistically to optimise muscle growth, strength, fat loss, bone health, and recovery—without the same level hormonal imbalances often associated with anabolic steroids.
Why Choose Golden Stack?
Each component in Golden Stack has a unique mechanism of action, making this stack a non-conflicting, synergistic combination that supports multiple anabolic and metabolic pathways simultaneously.
1. RAD-140 – Explosive Strength & Lean Muscle
Also known in the research community as Testolone, RAD-140 is a selective androgen receptor modulator that mimics the muscle-building effects of testosterone—without the harsh side effects.
Key Benefits:
Increases muscle size and strength
Enhances protein synthesis
Boosts fat oxidation and metabolic rate
Promotes muscle hardness and vascularity
Supports faster recovery and reduced inflammation
Furthermore RAD-140 is particularly ideal during recomposition or bulking cycles and is often praised for promoting dry, quality gains.
2. MK-677 – Natural Growth Hormone Booster
This compound is not a SARM but a growth hormone secretagogue, meaning it stimulates your body’s own production of growth hormone and IGF-1.
MK-677 Works Differently:
Activates the ghrelin receptor (GH secretagogue pathway)
Improves deep sleep and recovery
Increases lean mass without suppressing testosterone
Enhances fat loss and energy levels
Supports anti-aging, skin elasticity, and joint health
As it operates via a completely separate biological mechanism, MK-677 pairs perfectly with RAD-140 and LGD-4033 therefore completing this ultimate anabolic stack.
3. LGD-4033 – Muscle Preservation & Bone Strength
Also known as Ligandrol, LGD-4033 was originally developed to combat muscle wasting conditions, making it one of the most powerful SARMs available.
Why LGD-4033 Completes the Stack:
Significantly boosts muscle mass and strength
Aids in fat loss by preserving lean mass
Improves bone mineral density
Accelerates post-workout recovery
Reduces inflammation and joint discomfort
Moreover, Golden Stack uses LGD-4033 for its ability to maintain gains over longer periods while promoting overall body composition transformation.
Stack Synergy: The Science Behind the Combination
AGolden Stack isn’t just a mix—it’s a strategically engineered blend of compounds selected for their complementary effects:
RAD-140 and LGD-4033 both activate androgen receptors, enhancing strength and muscle development.
MK-677 increases growth hormone levels and improves sleep, supporting recovery and lean mass gains.
The three compounds do not overlap in pathways, reducing the risk of receptor saturation or unwanted suppression.
The result? Maximum results with minimal interference.
How to Use Golden Stack
Each bottle of Golden Stack contains the ideal research ratio of RAD-140, MK-677, and LGD-4033.
Typical Research Protocol (Example Only – Not Medical Advice)
RAD-140: 10–20 mg/day
MK-677: 20–25 mg/day
LGD-4033: 5–10 mg/day
Cycle length: 6–8 weeks for optimal research outcomes
Post-cycle recommendations: Consider a PCT Supplement if research suggests any hormonal suppression.
Golden Stack is sold strictly for research purposes and complies with UK regulations for SARMs distribution. It is not intended for human consumption.
Note: For research purposes only.
Will Golden Stack cause side effects?
When used responsibly in research settings, SARMs like RAD-140 and LGD-4033 may exhibit mild hormonal suppression, while MK-677 typically does not. Always consult independent data and studies before beginning research.
How long do results take to show in research?
Early research data suggests noticeable changes in muscle density and strength within 2–4 weeks.

December 19, 2025
Ran the Golden Stack up to Christmas to say everything’s gone in the right direction would be an understatement! The 8kg extra weight has definitely got me comments so overall very impressed
November 17, 2025
Smashed several PB’s again including a nice one on the DB bench press that’s been holding me up for a while now. If you’re prepared to get everything on point then this product will not disappoint!!

Just coming up to date 60 with 13kg ish gain. Hoping to push 4 more to hit 90kg. Looking incredibly good at the minute; the products in combination with a mega high calorie count and muscle memory really has paid dividends
September 25, 2025
Some time ago due to certain health issues I had to leave anabolics alone and have been happy taking sarms. Out of the lot I think Golden Stack has been the one that has made the most difference in terms of how I look and feel. My joints felt it towards the end, especially my elbows but nothing I couldn’t cope with and I am approaching 60.
September 17, 2025
Exceeded expectations tbf – top product 👌
August 11, 2025
Always a smooth and fast transaction with no problems. Great product and great to deal with, recommended.
July 7, 2025
Did the 90 day golden stack. First few weeks you might not think much is happening but by the end the gains were huge and you felt so pumped up. Lifted more than previously. Highly recommended will be doing it again definitely. Great support with help, answers and guides to doing it right. Don’t be afraid to ask if your not sure. 5 stars

I’m 45 years old and was somewhat flagging in the gym especially as regards recovery and energy so decided to give this Golden Stack a go. Kicked in after the first week, great supplement with very noticeable effects. Strength, energy, sleep all improved when taking this. Will be back for another cycle upon completion of PCT
May 30, 2025
Cycle went great I started off at 78kg finished at 80kg I did eat loads but didn’t put on that much weight tbh but my strength shot up loads I could only just about bench 90kg now I can do 115kg and I do look a lot bigger so has definitely worked well Im only 20 years old so will definitely be able to put more weight on by the time I’m half way through my 20s but yeah really good cycle that was my first ever cycle aswell but now just gonna go back to creatine and then will prob jump back on later in the year

Pretty potent stuff that kicked in early for me. Strength began to increase in the 2nd week alongside feeling super motivated. Had a few questions and concerns and don’t often get customer service this attentive and urgent. Looking forward to making more gains this year!
November 29, 2024
Gains on this stack far exceeded expectations having previously tried the MK2866 a long time ago from another company. Anthony is a very sound guy honest and helpful and I appreciate it as you can order supplements from places that won’t even reply or deliver it on time. Thank you very much , I’ll definitely be back after my PCT
November 14, 2024
Excellent supplement that helps you get were you need to be with your exercise and strength to build your body to another level. Super fast delivery with tracking, exceptional service all-round really which is a rarity nowadays.

September 11, 2024
Quality is very good
August 6, 2024
I’ve seen great improvements from these consistently gaining 3-4 pounds per week. I can’t believe how well they work. It’s a credit to AN that your supplying such a good product and offering sound advice in the process.
July 11, 2024
Absolutely loving this cycle. Put on 4kg in 5 weeks and look leaner on a small surplus of calories. A* service all around will definitely be ordering again thanks
June 17, 2024
Super stack that delivers on its claims at a good price with next to no sides (you will require PCT). Also customer support is excellent, always clear, helpful and a pleasure to deal with. Not really suitable for beginners but can recommend to anyone serious about making gains 💪
May 18, 2024
On to the 2nd bottle and so far I'm gaining some good weight. Strength and energy levels are well up too feeling very motivated and back to loving every sess!
April 29, 2024
Very good product, noticed big improvements in strength, recovery size and sleep. Motivation is always there too and touchwood, I’ve not experienced any side effects either.
April 19, 2024
The results this Golden Stack delivers are unreal. Great increase in strength, muscle size and endurance with no noticeable side effects.
March 20, 2024
Have made several purchases from these guys now and the products are always spot on and reasonably priced compared to other companies I've used before.
The main reason for leaving this review though is because when I hit a technical glitch on the site the other day, the customer service was spot on. Fast reply to my email, quick fix of the issue and all around very helpful.
Made a really nice change to some of the a.holes I've dealt with in the past so big thumbs up to Anthony from me and I highly recommend anyone considering a purchase not to hesitate as these folks and the products are the real deal and as professional as they come.
Very regards Gaz

I was sceptical at first but had read a lot about SARMS on the internet. I came across the Affordable Nutrition website when searching for MK-677 and after speaking to Anthony, I was convinced that the Golden Stack was for me. Delivery was fast and the product arrived well packaged. 1 week in, as a 51 year old I’m feeling energised like a man 20 years younger, enthusiastic about my training and can’t wait for the strength gains. I’m sleeping better and my mood is heightened with no adverse side effects. If you are considering trying this product, I promise you that you won’t be disappointed, it’s truly awesome.
Thank you Affordable Nutrition.
January 24, 2024
Super good & super fast delivery!
December 19, 2023
Awesome product! Finished my first 60 day cycle and very happy with gains to date. Delivery is always super quick and reliable. Will order again.
October 18, 2023
First time I’ve tried anything like this and having done my research this product ticked all the boxes. I was bracing myself for side-effects that to be honest never materialised. After 2 months of “researching” I’m nearly a stone heavier and even bit leaner. Weights have increased on everything and I’m recovering like Wolverine!! Anthony very kindly emailed me some top advice for PCT which is an absolute credit to him and this business so heading into the next few weeks feeling great
September 7, 2023
Absolute BEAST of a product!
August 4, 2023
Great Stuff!!
July 10, 2023
Here’s deal I was sceptical at first but currently month into my first golden stack, and prior to taken I had been stuck on sub 100kg bench press. I’ve now breached that with 100kg for few reps and that’s increasing now. I recover quicker than I ever have. No negative symptoms, getting good shape on me as well. Team at affordable have been great with their support as well ! Can’t recommend this enough !
June 8, 2023
Brilliant product!
May 17, 2023
A bit pricey for a full course and doesn’t work as fast or as well as test but does the job with minimum sides. A good option if like me you want to transition off the gear
May 5, 2023
I'm leaving a review because this product works! It's a shame I can't post before and after pics after completing a 60 day cycle. I'm bigger, stronger and 5 kilo heavier but also leaner?! Now onto the PCT protocol that Anthony has very kindly provided me with. Finally a reliable sarms company that's legit and run by a top man
April 22, 2023
Felt a difference in strength after 7 days of taking and my sleep has been amazing since I started. Had a question about MK677 which was answered by Anthony in an hour and arrived next day on the standard service. Very impressed and can highly recommend.
April 19, 2023
I don’t usually write reviews however I’ve seen a massive benefit with this product. I’ve been training for 3+ years so I’ve tried a few products but always struggled to gain weight without looking skinny fat. This product is a genuine game changer!
April 12, 2023
This product is 100 % real deal, will stick with this brand for the foreseeable future. Super fast delivery too!
April 1, 2023
Never had anything like this before. I’ve tried a few of these stacks on and off for the last 3 years but this feels like an entirely new type of product. Strength has gone through the roof can highly recommend it!
March 21, 2023
Excellent product and delivered very speedily
