RAD 140 is one of the most versatile SARMs created and can be used for bulking and cutting cycles. This opens up a lot of doors when it comes to stacking it with other compounds to aid a cycle’s objective further.
Unfortunately, there is much contradicting information on correctly stacking it online, which leads many users to create Frankenstein cycles and have horrible experiences.
In this article, you will learn how to effectively stack RAD 140 with other SARMs & research chemicals based on the best stacking practices from the SARMs community, analysis of the latest academic data, and the thousands of anecdotal experiences reported online
/*! elementor - v3.11.5 - 14-03-2023 */To achieve the best results, stacking should focus on the principle of synergy, which involves combining SARMs that work through different mechanisms of action to achieve ridiculous results.
For instance, stacking RAD 140, which acts through the androgen pathway, with YK-11, which acts through the myostatin pathway, to leverage both muscle building mechanisms.
Similarly, combining RAD 140 with Cardarine, which works through the peroxisome proliferator-activated receptor pathway, or MK 677, which operates through the growth hormone pathway, can lead to synergistic effects in terms of muscle growth, or fat loss, depending on your objective with the stack.
The table below showcases what you can stack RAD 140 with to achieve synergy.
| DON’T STACK WITH | DO STACK WITH |
|---|---|
| LGD -4033 (Ligandrol) | YK-11 |
| S-23 | MK677 |
| S-4 (Andarine) | Cardarine |
| MK-2866 (Ostarine) | Stenabolic |
| LGD-3303 | GW0742 |
| ASS – Anabolic Androgenic Steroids |
I’ve also created this spreadsheet which shows you which SARMs and RCs you can combine based on the same concept.
If you want to learn why this concept works, keep reading.
Further down the article, you will also find examples of bulking, cutting, and recomp cycles with detailed instructions and “advanced” concepts of side effect mitigation, on-cycle and post-cycle therapy, and generally each step of crafting THE optimal stack.
Synergy is the concept of combining SARMs that work through different mechanisms of action. This leads to vastly better results and less side effects than stacking regular SARMs that do the same thing.
This concept has been confirmed by most of the anecdotal cases where users stacked regular SARMs with each other, and got a disproportional increase in side effects to benefits.
For example, a lot of users that stacked RAD 140 with LGD 4033 experienced a small increase in benefits compared to just taking one or the other, while the testosterone suppression and impact on organs were significantly higher.
Why does this happen?
A theory is that SARMs that work through the same pathway compete for the same receptors. And the one with the higher binding affinity wins, kicking the other one out of the receptor and making it useless.
The idea is to stack SARMs & PEDs that work through different pathways, that way they act on top of each other and amplify each other’s effects, rather than competing with each other.

In this stack, we are using RAD 140 as the main muscle growth and strength driver, and the addition of MK 677 to help with recovery, boost sleep, muscle growth, and even fat loss (by leveraging MK 677-induced lipolysis and nutrient partitioning).
Depending on your objective, this cycle can be used for bulking or cutting.
If you use this cycle for cutting, you will almost certainly need to run a PCT in the form of a SERM for 3 weeks at a low dose. This is because any suppression RAD 140 causes would be exacerbated by the caloric deficit.
If you use this cycle for bulking, you might be able to get away without doing a PCT.
Needless to say, if you increase the dosage of RAD 140 to 15mg/day or more, you will almost definitely require a PCT, and a test base would also be very beneficial.
In the example table above I’ve upped the dose of RAD 140 mid cycle, and selected Enclomiphene as a test base and PCT in the form of a SARM+SERM protocol. But any SERM will work.
I’ve also extended MK 677 use post cycle as a “non-suppressive” PCT. Though this is completely optional.

This stack is reserved for the pros.
It incorporates RAD 140 at a dose of 15mg/day for the first 4 weeks, and 20 mg/day with the addition of 10mg/day of YK11 for the final 4 weeks. MK 677 is also dosed at 20 mg/day for the entire 8 weeks, and 10 mg/day for an additional 4 weeks after the cycle.
YK11 will inhibit myostatin and greatly amplify the muscle-building effects of RAD 140. On top of that, MK 677 will boost recovery, improve appetite, and quality of sleep, and most importantly act to mitigate the typical joint dryness that YK11 causes.
This is exclusively a bulking stack and should not be used for cutting. The reasoning is simple. You would be wasting a lot of the muscle-building potential from RAD 140 and YK 11 in a caloric deficit.
This cycle will be highly suppressive so you will have to do a test base and PCT. In this example, I’ve used Enclomiphene, but you could also use 4-Andro as a test base followed by a double SERM PCT for four weeks.

This stack incorporates RAD 140 at a low dose of 10mg/day to help maintain muscle and strength, with Cardarine at 10mg/day to burn fat and improve cardiovascular ability.
Cardarine could be replaced by similar RC’s that have the same/similar benefits, but don’t pose a risk for cancer. These include:
In my opinion, RAD 140 by itself is more than enough for a solid cutting stack. It will definitely retain all muscle, and may even allow one to make small gains during a cut if the deficit is not aggressive.
In conclusion, stacking RAD 140 with other SARMs or research chemicals can yield great results if done correctly. It’s important to focus on the principle of synergy and combine compounds that work through different mechanisms of action to amplify their effects.
The article provides a useful table and spreadsheet to help guide your stacking choices, as well as examples of bulking, cutting, and recomp cycles. Lastly, spend the time to find a legitimate source and get high-quality RAD 140, and consider using ancillary supplements like NAC and fish oil to further mitigate any potential side effects.
