How To Run A SARMs PCT (Updated 2020)

The Best SARMs PCT: Ultimate Guide (Updated 2024)

One of the most commonly asked questions we get – do you need PCT for SARMs and what are the best SARMs PCT products to use?

First and foremost, SARMs PCT protocol is a highly debated and subjective matter depending on the individual so we can’t advise you on what you should/shouldn’t do but we can give you some guidance.

In general, a person cannot be sure which option is best for them unless they get bloodwork done pre and post cycle. Every individual is different and the many factors that will affect your requirements include:

  • Your starting point/baseline
  • Any previous supplement/cycle history
  • Your predisposition/genetics
  • Your age
  • Which compound(s) you are using
  • The dosage(s)
  • The length of your cycle
  • How your body reacts to the compound(s)

Do SARMs Require a PCT?

SARMs, or selective androgen receptor modulators, can have an impact on the body’s natural testosterone production. SARMs can suppress your body’s ability to produce testosterone, which can lead to a decrease in testosterone levels and consequently a range of negative side effects, such as decreased libido, low energy levels, and muscle loss.

To preserve your progress, a crucial step to consider is implementing post cycle therapy (PCT). PCT gives the body time to restore its normal testosterone production and helps offset side effects associated with SARMs.

By utilising these specific supplements or medications during this period of recovery, users are able to maintain their hard-earned gains without compromising any health concerns.

It’s important to note that not all SARMs require PCT. The need for PCT can depend on the specific SARM, the dosage used, and the length of the cycle. It’s always best to consult with a healthcare professional before starting any new supplement or compound, and closely monitor your body’s response during and after a SARM cycle.

The Three Different SARMs PCT Protocols

In general, there are two options to look at when considering your SARMs PCT protocol. These guidelines are NOT instructions – it is down to you as the individual to make a judgement call (or get bloodwork done) in order to choose the best and most effective course of action:

  1. A mild over-the-counter PCT stack that includes an aromatase inhibitor (Arimistane) such as Pro PCT, combined with a high-quality natural testosterone booster. This is almost always the best option after an Ostarine cycle. For some people, this is also a suitable option for other mid-range SARMs such as LGD-4033, LGD-3303, S-4), and/or shorter cycles up to 8 weeks.
  2. A potent over-the-counter PCT such as Pumping Iron Pro PCT (6-OXO) which is powerful enough for SARMs and pro hormones alike.
  3. A full PCT which includes a SERM, such as Nolvadex and/or Clomid. Ensure to do thorough research on PCT protocols before you consider researching SARMs. This option is often recommended for potent compounds (such as RAD-140, YK-11, S-23), advanced stacks and longer cycles of 12 weeks.

There is also added benefit of adding Cardarine and a low dose of Ostarine to your chosen SARMs PCT protocol, which we go into detail further below.

What is Pro PCT (6-Oxo)?

Pumping Iron Pro PCT is an advanced SARMs and prohormone PCT that contains 6-OXO, a potent aromatase inhibitor which should only be used by experienced users of SARMs and prohormones.

This supplement is intended for male athletes only and shouldn’t be used by women. PRO PCT can be used to prevent estrogen related side effects on-cycle as well as a powerful recovery agent for post cycle therapy (PCT)

What are SERMs?

SERMs (Selective Estrogen Receptor Modulators) – not to be confused with SARMs – help to control the effects of estrogen and ultimately helps you to avoid gyno (gynecomastia), maintain the muscle mass you’ve gained during your cycle and to boost your testosterone levels.

The pharmaceutical grade SERMs are most effective but in some cases, you can use an over-the-counter supplement if your cycle consists of a very mild compound that isn’t too suppressive. The more potent the compound (or the stronger your cycle) the better your SERM needs to be.

The two most common and effective SERMs are:

  1. Clomid (Clomiphene Citrate) is a pharmaceutical drug that has the ability to inhibit estrogen formation. Clomid is often used for heavy cycles or those stacking several compounds. This is because Clomid is the strongest PCT compound but which also carries the greatest side effects. Most users prefer to stick to Nolvadex for their SARMs PCT unless they have no other choice.
  2. Nolvadex (Tamoxifen Citrate) is a pharmaceutical drug used after most steroid cycles to help the user recover. It is a mild yet effective compound which is it’s often preferred over Clomid.

Some users will use a low dosage of Clomid and Nolvadex in their PCT protocol rather than pick one, or the other. This prevents the potential emotional side effects users can experience by using a high dosage of a single SERM.

To further enhance recovery, it is recommended to include a good natural testosterone booster, a liver/organ detox supplement, an aromatase inhibitor, Ostarine and Cardarine.

A quick search on SERMs and you will find many articles relating to the use of both Clomid and Nolvadex, these can be combined together or used solo.

Preparation is key. One thing we can recommend is always having both options on hand in case you find that you need to run a full PCT, even if you haven’t anticipated this possibility.

Signs of Testosterone Suppression

You can also make a judgement on the signs of testosterone suppression if you experience any of these:

  • Low energy
  • Low libido
  • Feelings of sadness
  • Loss of strength and motivation
  • Chronically poor performance in the gym

Assess how you feel after finishing the cycle and this should give you an idea of the degree of testosterone suppression. This also applies after you complete your SARMs PCT to assess the indicators of a successful post cycle therapy.

Always ensure to take enough time off between cycles to ensure adequate recovery; listen to your body and if in doubt, take more time off.

Should You Use an Aromatase Inhibitor During your SARMs Cycle?

Although some supplements and SARMs do not convert to estrogen, you will still get the odd one or two guys who experience estrogen-related side effects during their cycle. In such cases, a mild over-the-counter SARMs PCT supplement with an aromatase inhibitor is ideal.

Mild suppression of testosterone will throw your estrogen levels out of balance and therefore can cause side effects in those who are more prone.

Ostarine Prevents Catabolism During PCT

At this transition point, your body will quickly begin to produce testosterone. It’s here you must be careful not to allow excess cortisol from chewing up your hard-earned muscle. At the same time, your body will have little to no nitrogen which will cause your muscles to crave nutrients that you don’t have.

To counter these effects, prevent catabolism and lessen the amount of muscle loss, a sensible solution is to introduce a non-suppressive anabolic; and this is the greatest opportunity for this SARM to really shine.

A low dose at 10mg of Ostarine (MK-2866) will help preserve your muscle gain and increase your nitrogen and IGF levels. This will also help you continue smashing your workouts and even improve muscle pumps.

Cardarine Prevents Fat Gain During PCT

After you’ve dealt with your cortisol levels, you’ll find that the excess testosterone binds with it, rendering it inactive. To prevent fat gain yet keeping your calories up requires a PPAR modulator such as Cardarine (GW-50156).

This will regulate the rate at which you burn fat. It does this in a number of ways but essentially it promotes glycogen retention in muscle tissue. This allows the body to alter its metabolism and increase the amount of fat burned instead of using carbs or protein as fuel.

This is a true win/win and means your body retains muscles and yet fat retention is reduced. This, in turn, will give you more stamina and can have the added bonus of reducing cravings.
