Rad 140 and LGD 4033 are often looked at as equals in terms of their lean muscle-building potential, and their natural testosterone production suppression. But is that all there is to it? And if so why even bother to choose one over the other?
While they do add a very similar amount of muscle, RAD 140 and LGD 4033 differ tremendously in their remaining properties.
When picking one over the other, it all comes down to assessing:
Each SARM has its own unique strengths and weaknesses, and on paper, there is no winner. The point of comparing them is to find which one suits you best based on their properties and how well your body responds to each. By familiarizing yourself with the properties of each compound, you are putting yourself in the best possible position to make an educated decision.
This article will help you do exactly that.

Both will also cause dyslipidemia (cholesterol panel disbalance). Their remaining properties all differ:

For those wondering, the LGD flu is a Ligandrol-specific symptom that manifests by an upper respiratory tract infection for no apparent reason. The majority of users do not experience it, and when it does happen it lasts 3 to 5 days. The symptoms are that of the common flu.

As you can see RAD 140 and LGD 4033 have a plethora of differences.
In terms of benefits, those are:
In terms of side effects, those are:
Of course, the spectrum of side effects across both varies from person to person. But generally, going by these, you are able to make a distinction on which one would suit your goals better.
For more detailed information, read my more comprehensive guides which I linked to above.
LGD 4033 is people’s go-to compound for bulking cycles, while RAD 140 is more versatile and can be used for both bulking and cutting cycles.
From an 8-week LGD 4033 cycle one can expect gains of up to:
From an 8-week RAD 140 cycle one can expect gains of up to:
For a more detailed and visual picture of what you can expect from RAD 140 and LGD 4033 take a look at these 15 before and after RAD 140 transformations and these 12 before and after LGD 4033 transformations.
Both RAD 140 and LGD 4033 should not be taken for over 8 weeks. Users often experience a plateau and diminishing returns after 8 weeks. The reason why is still unknown, but many speculate that it’s just because of an increase in myostatin.
In terms of suppression:
To determine whether to PCT or not after a RAD 140 or LGD 4033 cycle visit my PCT for SARMs guide where I explain it in great detail.
NOTE: If you’re using either one for a cutting cycle, you will have to do a PCT, and possibly even a test base.
Protocol cheat sheets:
You should never stack RAD 140 and LGD 4033 because they work by the same mechanism of action, and will end up competing instead of complimenting with each other.
This is a universal practice that applies to all SARMs. Everyone wants to stack LGD 4033 and RAD 140, or MK2866 with RAD 140, or S4, etc…
Combining “normal” SARMs is not optimal, and carries much more risks and far less benefits than just running one SARM at a higher dose.
The theory is that SARMs fight to attach to the same androgen receptors, and that the SARM with the higher binding affinity ends up kicking the other SARM out of the receptor (making it useless).
There is no scientific proof to back this theory up, but there are heaps of anecdotal cases that make it obvious. If we look at users that combined RAD 140 and LGD 4033, almost all of the time what happens is a miniscule increase in muscle compared to just running one. On top of that the test suppression and other side effects (lipid panel, enzymes) go through the roof.
Instead combine SARMs that have a different mechanism of action to create a synergy:
– YK11 (myostatin pathway) with SARM (androgen pathway)
– MK677 (GH pathway) with SARM (androgen pathway)
– SR-9009 / Cardarine (endurance) with SARM (androgen pathway)
While RAD 140 and LGD 4033 are equals when it comes to the amount of lean muscle they can build and the level of suppression they cause, they differ tremendously in other areas.
You should by now be fully aware of their unique properties, and be able to make an educated decision on which one better fits your goals and expectations. To conclude, there is no winner. Both have their pros and cons, and different people will have a different reaction to either one.
