Your Ultimate Guide to Post Cycle Therapy

If you are considering a cycle of anabolic steroids or prohormones of any kind, then it is crucial that you read this entire article on post cycle therapy. 

Post cycle therapy is a process that involves specific compounds, nutrition, and often pharmaceutical drugs to help control levels of estrogen, re-regulate hormonal levels and get you back to normal after a cycle of prohormones/steroids.

If you don’t have a good post cycle therapy planned ahead of time, you can face side effects like gyno, high blood pressure and even a loss of almost all the gains you made.

This article will help you get an idea on what a good post cycle therapy looks like so that you can have a successful cycle as well as keep all your gains and stay healthy.

Post Cycle Therapy 101

An effective post cycle therapy often includes a few things:

  1. SERM (or Selective Estrogen Receptor Modulator)
  2. An Aromatase Inhibitor (or AI)
  3. Other PCT supplements as well as on cycle support. This may include pharmaceuticals, testosterone boosters, and other natural or herbal supplements.

Each one has a very special role in your PCT and are all crucial in assuring a successful cycle and long lasting gains.

Let’s talk about the first one…



Taking a SERM (Selective Estrogen Receptor Modulator) will help to control the effects of estrogen so you avoid gyno (bitch tits), help you maintain gains, and boost your testosterone levels.

These are often pharmaceutical grade and work the best, but in some cases you can use an OTC product, especially if you took a very mild prohormone. Typically the stronger your cycle, the better your SERM needs to be.

Remember, increased testosterone = increased estrogen levels.

Keep that in mind when planning your PCT so you’ll stay balanced not only throughout your cycle but post cycle as well.

The three most common and effective serms in order of recommendation is:

1. Nolvadex

Aka Tamoxifen Citrate, Nolvadex is by far the most popular SERM when it comes to post cycle therapy and in my opinion your best option.

Recommended dosing is 20-40 mg per day, and the length of time you use it depends on the strength of the cycle (see below).

2. Torem-fareston

Toremifene citrate is similar to both clomid and nolvadex, and is popular by steroid and prohormone users alike as it not not only helps prevent gyno but may even increase testosterone levels.  

Although there are no human studies on the drug, because it works very closely to both Nolva and Clomid, the effects on testosterone would logically be the same.

Recommended dosing is 60-100 mgs per day.

3. Clomid

Also known as Clomiphene Citrate is probably the 2nd most popular option other than Nolvadex, and although the two are similar, Clomid is actually a weaker anti estrogen and needs to be dosed higher at 150 mg to achieve the same effect as Nolvadex.

It’s very effective, but when factoring in cost, I’d go with Nolvadex or Torem any day when available.

However, you can still buy Clomid for pretty cheap and it’s been proven throughout the years to be great in any PCT.

Aromatase Inhibitors (AI)

#2: Aromatase Inhibitors

AI’s (or Aromatase Inhibitors) are the 2nd piece to the post cycle therapy puzzle and basically block the conversion of testosterone to estrogen via the Aromatase enzyme.

AI’s are often used during the cycle itself but can also be added to the end of a cycle to help eliminate and decrease estrogen levels.

One of the more popular AI’s, Letrozole, has been found to decrease estrogen by 96-98%! It's incredibly potent stuff, and also known to eliminate gyno very quickly.

AI’s are important to help you increase gains while on cycle, and to maintain normal, balanced hormonal levels.

So if both AIs and SERMs deal with estrogen, why do I need both and what’s the difference?

The answer is that AI’s help to eliminate the conversion of estrogen at the source during cycle, helping to eliminate bloat and increasing gains. SERMS are for damage control at the end of a cycle, to help prevent the estrogenic effects such as gyno and loss of gains as well as increase testosterone production naturally.

Here is a simpler way to picture out the whole thing: AI’s prevent the adverse side effects of having too much estrogen in the body by keeping testosterone levels up to par in the body. On the other hand, SERMS help stimulate the ideal production of testosterone supporting the activity of the luteinizing hormone (LH) to keep the negative side effects of having too much estrogen levels from taking place. Moreover, SERMS also ensure that you won’t experience any testicular shrinkage while at it.

Since you can’t block estrogen forever, combining an AI to help eliminate increases in estrogen with a SERM will assure you end your cycle looking better than ever with little side effects and lots of muscle mass.

PCT Supplements

#3: Cycle Support & Other PCT Products

Post cycle therapy doesn’t end with just SERMS and AIs. You also need a variety of other products to keep organs healthy, control blood pressure, cholesterol and maintain testosterone production in more natural ways.

SERMS and AIs often have a variety of side effects including emotional episodes, vision problems and loss of libido.

I suggest continuing post cycle with alternative products that will help you to control estrogen, keep your test levels high, and protect you from many of the side effects you may experience while on a cycle of prohormones.

If you are taking a milder prohormone, or want to increase the effectiveness of your pharmaceutical PCT, then adding a couple of OTC PCT supplements leads for great results.


Below are some of the most common questions I get regarding PCT…

Where can I buy legit SERMS online?

I’m often asked where you can find these SERMS and which are the most trusted places to get them. This isn’t always easy to, and is actually pretty risky, especially when buying overseas.

There is really only one place I recommend as of today (August 2017)

Sarms1: I’ve used these guys for years. They ship fast, discreet, and everything is always super high quality. You can buy both SARMs as well as any major PCT product on their site in liquid form. They’re one of the big guys when it comes to stuff like this. I have personally had gyno and used the Liquinol and Liquifem from this place and completely eliminated it in a few months. Truly amazing stuff.

Also, the customer service is great. I highly recommend you pick up one of the three above and have your PCT ready before you even start your cycle of prohormones, SARMs or anabolic steroids. Trust me, this is a lesson I learned the hard way.

Where Can I Buys AIs (Aromatase Inhibitors) like Letrozole Online?

You can pick up some Letrozole at our recommended source.

How should you dose your SERMS for maximum effectiveness?

This will vary, depending on the harshness of the cycle. If you are taking more than two prohormones at a time, you will want a stronger dose of a SERM compared to a milder cycle or if you are taking a non methylated prohormone.

Below is an example guideline for a normal cycle, followed by an example for a stronger cycle:


As you can see, a SERM depending on the strength of your cycle will be stronger to combat the effects of hormonal levels and then are slowly decreased over 4 weeks. You will typically take a SERM for the same length of time you spent on cycle.

What is the most effective over the counter PCT supplement I can take?

At the moment, the highest rated PCT supplement is Gainz Insurance by BOSS Sports Nutrition.



  1. I’m 5_10 175 built well gonna run test e at 500 a week for first cycle. Gonna do clomid and nolva for pct 18 days after last pin. Do you recommend running hcg during my cycle or will I be fine wo it.. Also would like to Kno what worked well for other

    • If your 5’10 175 your built like a girl

    • How old are you? 500mg might be high if you’re in your early 20s and don’t plan on competing. Start with a TRT dose of 250mg for your first cycle. It’s always best to start low and build up. If you start to high where do you go from there? Up and up and up.

  2. Hi I’m taking 20 mill Of oxymetholone and and 25 of provirone all oral. Should I be taking anything along with this or anything post therapy?

    • hook yourself up to a dialysis machine because it’s not only stupid to only run orals but your liver is gonna die. If your gonna do it do right. Meatball

    • Chlomid, hcg and aromasin is ideal. Your body is not going to bounce back. Srop the oxymetholone asap.

  3. I have already taken

    Thank God I wasn’t born with a small dick….overcompensating with steroids would suck. And, once the pants come off, the package remains the same. Idiots.

  5. Hi, I’m 33 years old and planning on taking my first cycle. I’ve been recommended 100mg Tren every 4 days for a month. Is this low? Would I still require a PCT?
