Top 6 Best Post Cycle Therapy Supplements

When it comes to getting massive, adding muscle, and increasing strength, your focus is always on supplementing for size.

Whether it’s a testosterone booster, D-aspartic acid, 1-andro, or 4-andro, you take them in a cycle and workout like a fiend during that time.

However, what happens when you cycle off?

Contrary to popular belief, it may be even more important to hone in your post cycle therapy than it is to take tons of muscle-building supplements for a few weeks.

The focus for post cycle therapy is to rebalance your body’s natural hormone production; therefore, you want to optimize your PCT so you can get to the next cycle with a healthy basis.

Here is the definitive guide to post-cycle therapy.

In this article, we’ll go over what PCT really is, who needs it, where you should get your therapy, whether they work or not, benefits, dosage, side effects, and our top PCT supplements you can get today for your next post-cycle timeline.

Let’s get started!

For the quick list of the best PCT supplements, here ya go:

What is Post Cycle Therapy (PCT)?


Post cycle therapy is fairly straightforward.

It is a full-on transition period, where you go from taking some type of hormonal regulator to getting back to homeostasis. This allows your body to return to normal hormone production.

While your hormonal supplement might aid you in recovery after gruelling workouts, your PCT helps you recover from the additional hormones or upregulated production.

Post cycle therapy is essential to the entire process. Similar to a bulking/cutting split, post cycle therapy is what preserves your gains and also keeps you healthy.

Who Needs Post Cycle Therapy?

There are different camps of gym bros who take their favorite type of supplement. But do they need PCT to avoid side effects from their supps? Let’s tackle each category one by one:

Post Cycle Therapy for SARMs


Selective androgen receptor modulators are a collection of compounds that trigger your hormones to help grow muscle and burn body fat.

They act like steroids, but apparently steer you clear of the *ahem* unfortunate side effects.

But does it need to be cycled? As in, should you take your SARMs for a few weeks, followed by an amount of time on post cycle therapy?

The jury is still way out on SARMs as a supplement in general, and the same can be said for whether or not you need PCT…or even if SARMs is ideal for your post cycle therapy.

Allegedly, SARMs don’t affect the hormonal levels within the body, making them different from steroids or prohormone supplements.

Other research claims that while it isn’t on the same level as steroids in terms of suppression, SARMs still drops testosterone production in the testes.

Depending on your SARM supplement, you can either use it while in post cycle therapy or will be required to have PCT after taking it for a prolonged period of time.

Post Cycle Therapy for Prohormones

This is one of the main reasons why post cycle therapy exists. Prohormones essentially end your regular hormone production (i.e. your body stops producing it completely).

While there are benefits to supplementing with prohormones, it definitely causes adverse issues to occur within your body if you take them for too long.

That’s where PCT comes in; it helps you restabilize your body’s natural tendencies to create testosterone, reduce estrogen production, and regenerate liver cells (more on that later).

It doesn’t have to be said, but PCT after prohormone supplementation is a necessity.

Post Cycle Therapy for Steroids


Another given, steroids are synthetic hormones pumped into your system. You need a decent post cycle therapy to pump it all out and get back to basics.

Whether they are anabolic or a cleaner strain, they’re still messing with your natural hormone production.

Depending on how hard you supplement with steroids, you want to make sure your side effects are limited, as well as keeping your internal systems close to regular.

Prohormones and steroids are roughly similar, so a post cycle therapy session should be scheduled for immediately after supplementation.

Post Cycle Therapy with HCG

HCG – Human Chorionic Gonadotropin – is not a steroid, but instead “a natural peptide hormone which develops in the placenta of pregnant women during pregnancy to controls the mother’s hormones.”

However, it is also a natural stimulant to the Leydig cells in the testes. The Leydig cells are what produces testosterone.

HCG acts as the Luteinizing hormone that tells the cells to create more testosterone.

During long steroid or prohormone cycles, it’s good to use HCG to maintain the size of your testicles or to recover from atrophied testicles.

But, when it comes to post cycle therapy, it’s advised to not use HCG.

HCG is best used as a precursor to post cycle therapy, as it reestablishes your testosterone production levels from the testicles.

It isn’t a proper post cycle therapy supplement because it rapidly increases the creation of both testosterone and estrogen, which further represses the HPTA (Hypothalamic-Pituitary-Testicular Axis).

Therefore, it doesn’t help in recovery or restoration of natural testosterone production.

HCG: Use it during the cycle to avoid testicular atrophy, not in post cycle therapy.

Post Cycle Therapy with Nolvadex


Nolvadex is an alternative to Clomid, which has been found to have adverse side effects.

Technically, it is an estrogen modulator used to treat and help prevent breast cancer, plus you need a prescription for it.

This drug naturally increases testosterone production. A popular SERM (Selective Estrogen Receptor Modulator), Nolvadex is both a safe and an efficient way to restore your natural hormone creation within the body.

As far as supplementation schedule:

  • Day One of PCT = 100 mg
  • Next 10 Days = 60 mg
  • Next 10 Days = 40 mg

This should get you stabilized enough on a post cycle therapy regimen.

Post Cycle Therapy with Over-The-Counter

If you plan to go over-the-counter, there are certain ingredients you should look for and certain ingredients you should avoid.

However, it will be easier to obtain, seeing as they aren’t SERMs, which require a prescription from a doctor. (And if you aren’t a woman, good luck getting that.)

First, you’ll want a natural testosterone booster, which are plant-based compounds that – you guessed it – increase natural testosterone production.

Compounds such as Tribulus Terrestris and fenugreek are fantastic at doing this, with minimal to zero side effects.

The next thing you want in your OTC supplement is an aromatase inhibitor (AI).

This compound reduces the enzyme known as aromatase, which converts testosterone into estrogen, or something you definitely don’t want when recovering from using supps to add muscle.

Taking PCT with an AI helps the process of getting natural testosterone levels back to normal go that much faster.

Flavones, Flavanones, and Resveratrol are natural AIs that help reduce estrogen and increase testosterone.

Lastly, you want a cortisol control supplement. This can mean a ton of vitamins and minerals and should be easy to find.

Basically, cortisol is the stress hormone; by trying to get back to a natural homeostasis, your body will be under a lot of stress.

This reduces testosterone. So, adding DHEA, melatonin, a B-Complex, Vitamin C, or adaptogens will aid in controlling your stress levels.

As for other things included within your OTC PCT supplement, it’s best to steer clear of them.

The above three compounds are what you truly need to get back to a natural production state; anything extra won’t help exponentially, and in fact may do more harm than good.

Over-The-Counter PCT vs. Prescription?

When it’s time to choose your PCT supplement, there are pros and cons to whichever way you obtain them.

If you go with over-the-counter post cycle therapy capsules, there are some great benefits, such as cost, ease of access, and you get to choose which brand and PCT supplement you go with.

There are great OTC PCT supps out there (which we cover in our list below).

However, if you go with over-the-counter, you risk choosing a supplement that won’t react well with your body.

The capsule won’t be specifically tailored to your individual needs, which is why they can be somewhat inexpensive.

As for prescription post cycle therapy, there are obvious plusses: A catered prescription based on your blood type, an effective post cycle, and it is monitored by your primary physician.

Of course, the dilemma is cost and ability to find your PCT. While the availability is sometimes tough, it is mostly the cost that deters most bros from seeing their doctor.

And to that we say, “What’s your health worth?”

Whichever one you decide on, make sure it’s the best for you and your predicament.

Do PCT Supplements Actually Work?

In short, yes, they do work, but ONLY if you supplement correctly.

This means getting high quality post cycle therapy supplements that give you all of the important benefits, like natural testosterone production, estrogen reduction, and restoring normal bodily functions after a bout of steroids or prohormones.

In truth, you never know until you try. Perhaps specific PCT supps work well for you, while others fall far from expectations.

Trial and error should be your forte at this point, so find a few natural PCT supplements that have great reviews and high quality ingredients.

Experiment and discover your personal post cycle therapy routine.

How Do PCT Supplements Work?

As covered previously, PCT supplements take your inhibited hormone creators within your body and essentially “wake them up.”

During a cycle of steroids or prohormones, your body’s natural hormone tendencies and functions are either suppressed or shut down.

This is why you cycle between steroids and post cycle therapy.

You supplement additional hormones to upregulate the benefits of that hormone, then you get off that supplement and reestablish your natural production levels.

Most PCT supplements block aromatase, which turns testosterone into estrogen. It also uses natural testosterone boosters to help kick your Leydig cells into high gear.

Testicular testosterone activity ramps up to regular levels. Plus, it gives you an extra boost in keeping your other hormones at desirable levels, such as cortisol and metabolism.

How Long Does it Take for a PCT to Work?

There is no definitive answer. It mainly depends on how long your cycle lasts, as well as what you’re taking during your cycle.

Of course, your cycle should never last longer than 10 weeks as a standard rule.

That being said, if you are taking healthy prohormones without too much synthetic crap, you could get back to normal testosterone levels in around 2-3 weeks.

The full range could be from a week to four months. Test this out as well, because PCT is highly individualized.

Benefits of PCT

post cycle therapy steroids

Considering you did it correctly, cycling off of whatever steroid you were using has one major health benefit: It brings you back to normal levels of hormone production.

So long as you don’t do post cycle therapy for too long (a.k.a. don’t overdo it), PCT supplements give your body the ability to create its own hormones.

This is vital, seeing as you are now off the synthetic hormones you were taking beforehand.

PCT helps you avoid any adverse side effects from the steroids or prohormones.

Prolonged usage of these types of drugs will eventually result in shrunken testicals, hair loss, aggression, and many other complications.

Make sure you get your testosterone levels tested before cycling, at the end of cycling, and after your post cycle therapy, to get a sense of how much your body changes.

If you cycle on and off effectively, you should avoid side effects from the cycle and keep your natural testosterone levels intact.

Of course, the main benefit of PCT is the preservation of your hard-earned gains. That’s the whole point of taking steroids or prohormones in the first place, right?

Cycling off by ramping up natural hormone production will salvage the muscle gain and fat loss you acquired during your cycle.

Post Cycle Therapy Dosage

This topic is also dependant on what you take and what you’re cycling off.

As we said before, Nolvadex has a specific dosage cycle, and combining it with Clomid (not recommended) changes the dosage levels.

However, if we are talking about over-the-counter post cycle therapy, there isn’t a set length or dosage like with prescription medication.

To start, you have to wait a few weeks after your last steroid admission. The reason being is that there may still be androgens in your system.

High androgens actually waste your PCT supp because the androgen receptors are telling the testes to stop testosterone production.

Seeing as we are trying to upregulate testosterone production, we need to make sure the steroids are completely out of the system before engaging in PCT.

Here is a general breakdown of when to start your post cycle therapy based on type of steroid, along with how long you should be in post cycle therapy (from Fitness Uncovered):

SteroidWhen to start after last admissionLength of PCT
Testosterone Enanthate2 weeks3 weeks
Testosterone Cypionate2 weeks3 weeks
Testosterone Propionate3 days3 weeks
Testosterone Suspension6-8 hours3 weeks
Sustanon3 weeks3 weeks
Winstrol12 hours2/3 weeks
Dianabol6-8 hours3 weeks
Trenbolone3 days4 weeks
Deca durabolan3 weeks4 weeks
Primabolan depot14 days2 weeks
Anavar8-10 hours2 weeks

Prohormone cycles might differ. Some online forums claim you should start your PCT immediately after you get off prohormones.

It really depends on the half life of whatever it is you’re supplementing.

If there are androgens within your system, it might take a while to get them out. And if you start PCT before the androgens are out, you’ll be spinning your wheels.

As for dosage, follow the instructions on the bottle. The supplement companies know what they’re doing, and it shouldn’t take much to aid your body in getting back to normal.

Seeing as prescription drugs like Nolvadex and Clomid require minimal milligrams, OTC PCT should be roughly similar.

When Should You Take It?

Refer to the chart above for when you should start your post cycle therapy after the last steroid supplementation.

As for when to take it daily, in the morning with food is a great way to get the most bang for your buck with post cycle therapy.

Do I Need to Cycle a PCT?

shoulder press

Hopefully, this goes without saying.

You cycle steroids or prohormones, you cycle post cycle therapy, you repeat. Too much of either is never a good thing.

Keeping the timelines for both relatively short will enhance the benefits while reducing the side effects (more on these later).

Again, the length of cycle time depends on what you’re cycling off, how long your cycle was, and whether you’re going with prescribed SERMs or OTC.

As always, follow bottle instructions or doctor instructions. Also, get your testosterone tested to see where your levels are before beginning a cycle and post cycle therapy.

This will help determine how long you should cycle PCT.

Post Cycle Supplement Side Effects

side effects

For the hardcore prescription SERMs like Clomid and Nolvadex, there are a few common side effects, more often seen in women over men:

  • Vomiting
  • Nausea
  • Headaches
  • Blurred Vision
  • Acne
  • Diarrhea or Constipation
  • Upset Stomach
  • Skin Irritation
  • Depression/Anxiety
  • Loss of Libido

If you instead use SARMs – like HCG – you won’t necessarily have to cycle off this supplement. There are still side effects to these as well, including:

  • Gynecomastia
  • Hair Loss
  • Vision Impairment
  • Infertility

Lastly, OTC post cycle therapy have similar side effects as to the prescription ones, but they are less severe. Headaches, shortness of breath, blurred vision, and nausea are the main issues.

Of course, all of these are reduced if you follow the regimen to the letter, don’t prolong the cycle past where you should, and eat/exercise properly.
