You’ve probably heard it being mentioned a few times, ‘’SARMs do not require a Post Cycle Therapy (PCT)’’. They will and suppress your natural hormone production and in some cases, you will need a PCT.
Do SARMS require a PCT? It’s a question I hear quite frequently. To answer the question: Yes and no.
There are multiple factors that will play a role in whether you will need a SARMs PCT or not.
Which factors? Well first of all, which compound is being used and for how long. For example, 20mg of RAD140 for 12 weeks will be much more suppressive than an 8-week Ostarine cycle at 20mg
I would always advice to stock up on a product such as Rebirth PCT to help your body recover after the cycle
- Best SARMs PCT
- Strong Formula
- Recover From Cycles
- Increase Energy
- Boost Testosterone
- Maintain GAINS!
This is mainly because of the strength of the compound. Looking at both these SARMs milligram per milligram, RAD140 is so much stronger than Ostarine. It’s also worth mentioning that not everybody experiences the same levels of suppression.
SR-9009 (Stenabolic), MK-677 (Ibutamoren) and GW-501516 (Cardarine) do not require a SARMs PCT because they do not have an impact on natural hormone production.
Ostarine PCT
Ostarine PCT, 9 out of 10 times Ostarine does not require a strong PCT like Nolva or Clomid. Instead, you’re better off using Rebirth.
But why?
Well, Ostarine is the mildest SARM out there. It barely suppresses your natural hormone production and in my opinion, is a great compound.
It gives reasonable results and is basically side effect free. I really consider it to be great for cutting and recomping and even for muscle building, it is a good addition.
To give you an idea, I have run Ostarine at 20-30mg for 12 weeks without any issues at all. I felt great after the cycle and all I did was use Rebirth PCT which is amazing for recovery.
With Ostarine in general, a huge part of the users don’t seem to need a hardcore PCT. The stronger prescription PCT’s also have nasty side effects which you’ll rather want to avoid.
I highly suggest a product like Rebirth to help with recovery.
That’s always a good idea in my opinion. At the end of the day, your body is going to need all the help it can get.

A good PCT supplement like Rebirth contains a blend of different ingredients such as Arimistane.
It helps you lower estrogen whilst increasing testosterone. When your testosterone is increased, you’ll be able to keep your muscle gains you’ve made from the cycle.
I always suggest purchasing a testosterone booster when you’re coming off a SARM or prohormones cycle. They’ll help with maintaining gains, increasing energy and boost libido.
Of course, you want to be 100% sure you have legitimate Ostarine, I bought my Ostarine from Sarms4You.
LGD4033 PCT
Now, the stronger SARMs are a different story. Often RAD-140, YK11, S23 and LGD-4033 are considered the ‘’stronger’’ compounds.
They are more suppressive, especially when run at high doses for a longer period of time.
In these cases, you will most likely always require a PCT such as Nolvadex or Clomid. Pretty much every log I came across that involved these compounds the user ran a PCT after the cycle.
I do have to say that not everybody uses an LGD4033 PCT for a low dosage cycle of Ligandrol.
Personally, I only used a mild PCT after my 5mg 8-week LGD-4033 cycle and recovered just fine. Make sure to take a recommended product such as the Rebirth to help with recovery.
But when you run it for a higher dosage, let’s say 10-15mg for longer than 8 Weeks an LGD4033 PCT is definitely suggested.
SARMs PCT FAQ
You start your post cycle therapy the day after you have finished your SARMs cycle. Make sure to finish your entire PCT, it’s important.
If your just running a mild cycle, go with Rebirth PCT. It’s not as effective as Clomid or Nolvadex but you won’t need those.
What you need is a simple yet effective product that helps you recover without giving side effects.
It contains quality ingredients. You’ll find that it has D-Aspartic Acid, Arimistane and ZMA in it. Some of these ingredients have been proven to boost testosterone and lower estrogen.
It depends on which compound you’ve chosen but generally a SARMs PCT will last 4 weeks.
For example, I’ll start my Rebirth protocol directly the day after my cycle ends. I’ll take the recommended dosage of 6 capsules ever day for 4 weeks straight.
You shouldn’t really experience severe side effects during PCT. You might notice some fatigue but it’ll get better after you have succesfully ran the protocol.
SARMs PCT & Bloodwork
If you are able to get bloodwork done prior to your cycle I would really suggest doing so. Based on your hormone panel you will be able to see just how much of an impact the SARMs cycle has had on your testosterone levels.
Some people will choose to SARMs PCT based on how they feel. But when you have bloodwork done that will actually confirm if you need a post cycle therapy or not.
If your hormones are on the low end of the range and you feel horrible a good PCT will help you recover and get you back on track.
Of course, everybody will have their own opinion on whether you need a post cycle therapy (PCT) or not.
I think it is very important to do as much research as possible about the compound you are looking to experiment with.
Better safe than sorry!

Great write up.
I just started S4 and LGD-4033.
I’m doing 10mg of LGD and 25mg of S4 for two weeks to see my tolerance of S4.
Only doing it for 8 weeks. Do you think I would need PCT?
Hi Paulo. Thanks, I appreciate it!
I think in your case it would be a good idea to have it on hand. You might need it or not but at least you’ll have it nearby.
Another tip would be to get a test booster that contains solid ingredients. These are completely legal and will also help recovery.
Hi, one question, usually a run a stack of
Ligandrol 10mg 12weeks
Ostarine 25mg 12weeks
Rad 140 16weeks at 30mg
S4 at 50mg from 4 week to 16 week
After I do a pct of 3 weeks with clomif and 4/5 weeks with tamoxifen and gw501516 4 weeks at 20mg
Now I’m thinking in running all of that but put the S23 on the last 8 weeks of the cycle.
Do you think the same pct will be enough?
Also is good run only 8 weeks from the end and stack with all others compounds
Thanks and keep the good work, learn a lot with you!
Hey Ricky, thanks for the reply.
That’s a pretty big stack mate. To be honest, I wouldn’t suggest adding in S23. You’re already running RAD, LGD, and Andarine which are known to be suppressive.
But if you do plan on going through with i Think the PCT should be sufficient. Again, I highly recommend not adding in another compound like S23.
Good luck!
Great read, nice article! Question for you, I’m planning on running an 8 week cycle on cardarine and Ostarine. Going to run 10mg for the first two weeks then see if I want to up it or not, 10mg each that is. If I went any higher, do you think I should do a pct after?
And let’s say I add rad 140 and take away Ostarine, still low dose on the rad 140, but would stay low dose, would that require a pct after 8 weeks?
Thanks,
Jim
Well written article, Remi.
Soon I am starting a stack of GW-501516(10mg/12 week) and RAD-140(10mg/12 week). I am thinking of adding SR9009 as well, I am curious as to your thoughts. Also, do you think PCT would be a good idea if I included SR?
Thanks Remi!
Hi nice write up.
Would you recommend running a natural test booster durning an ldg cycle at 15mg per day for 8 weeks
how does alpha af compare to clomid pct? are they basically the same thing only clomid be stronger?
Hi i read your post thank you for sharing.
I am planning to take a 5mg lgd stack with 10mg rad140 for 8 weeks. Do you think ill need a pct for this cycle? Thank you.
I did rad 140 for about 6 weeks 10-30 mgs for the last two days I did 30 mg. . Will I need a pct I feel fine and kinda just wanna hop on Ostarine
