 What is a PCT? PCT stands for Post Cycle Therapy. A PCT is a cycle of one or more supplements or drugs, usually taken for 3-8 weeks. It’s aim is to reduce estrogen and stop any estrogenic side effects, increase and restore natural testosterone levels, minimise side effects and maximise your gains made during the cycle.
Do I need a PCT and what happens if I don’t do one?

Following MOST Sarms, ALL prohormones and ALL steroid cycles a PCT is needed. Chances are if you are reading this article you probably need a PCT…

In bodybuilding’s younger years PCT’s drugs and supplements did not exist so athletes tapered the drugs up and down, hoping for the best. But do not use this as justification to not complete a PCT. Drink driving was once acceptable but you wouldn’t do that this evening.

If you do not complete a PCT your estrogen levels are likely to raise to high levels, much higher than normal, whilst your testosterone levels increase at a much slower rate.

High levels of estrogen can can cause:
  • Gynecomastia (man boobs)
  • Becoming overly emotional
  • Fat gain
  • Muscle loss and water retention.
Lower testosterone levels can cause:
  • Lethargy
  • Muscle loss
  • Decreased confidence
  • Decreased sex drive.
Essentially by not doing a PCT you are deliberately acting against everything you have been working towards, as well as putting your health at risk.

The only reason someone wouldn’t do a PCT is cost… But we would say a PCT is the excellent value for money as without it you are potentially going to waste half the money that you spent on your cycle. Not to mention the fun emotional damage that comes along with the previously mentioned side effects which on its own is probably worth the cost of a PCT.

Poor planning should never be the reason for not having a PCT. You never know when someone might run out of stock or a product might be hard to find, so it is always best to have your PCT ready to go at the start of your cycle. Added to this if there is some form of emergency reason that means you can no longer continue your cycle; you don’t have to stress about the PCT because you already have it.

Do I need a PCT after using SARMs?  

A PCT is needed for anything that naturally suppresses your natural testosterone levels. Below we have listed out the SARM’s and whether a pct cycle is needed for it;

Ostarine – PCT?

Ostarine or MK-2866 being used up to 20mg for 8 weeks should not require a PCT. Higher dosages or longer cycle times will most likely need a PCT.

LGD (Ligandrol) – PCT?

LGD-4033 does require a PCT at any dosage and cycle length. In clinical studies testosterone levels went back to normal levels within 21 days with no PCT. However, the study may be at a lower dosage than you are considering, and if stacking with other products this will increase the shutdown effect.  

Cardarine – PCT? 

Cardarine or GW-50156 is also not technically a SARM and does not require a PCT as it does not impact testosterone levels.

YK-11 – PCT?

YK-11 is not a SARM but is a steroid and does need a PCT. You can read more about YK-11 HERE ⬅️

MK677 – PCT?

MK-677 is also not a SARM, it is a growth hormone secretagogue. It does not require a PCT as it does not impact testosterone levels.

Do I need a PCT after prohormones and steroids?

Yes. You’ll always need to do a PCT cycle after ANY prohormone or steroid cycle as they directly suppress your natural testosterone levels.

I’ve messed up, can I get a PCT from a doctor?

Sadly, it is highly improbable that the NHS would instantly bail you out of the situation right away. As we have such a brilliant healthcare service if you may have caused bigger or longer-term issues then I am sure the NHS could help but they don’t go around handing out PCT drugs to everyone. Which are often drugs used for cancer treatment.

What is the best PCT?

There is no best PCT for all situations, however, there will be a best singular or combination PCT for your situation. As PCT protocols/drugs/supplements, just like anabolics, are different strengths they can potentially can cause another set of side effects.

What are the different types of prescription PCT?
Clomid PCT

Clomid is the brand name for clomiphene which is SERM aka Selective Estrogen Receptor Modulator. It has been approved for use in the United States since 1967 and is prescribed to treat infertility in women who do not ovulate. Used normally for a total of 5 days for this scenario. When effective in this situation twins are also more likely. So why do people take clomid after a cycle? Clomid blocks estrogen from interacting with the pituitary gland. When estrogen interacts with the pituitary gland, less luteinizing hormone (LH) and follicle-stimulating hormone (FSH) are produced. Leading to a decrease in testosterone.

Clomid PCT Dosage 

Clomid is usually taken during PCT at 50mg per day for the first 2 weeks and 25mg per day for weeks 3 and 4. You may see some people for very heavy cycles, venture even higher with their dosing. Clomid can cause headaches, mood swings and vision problems in a minority of users.

Nolvadex PCT / Tamoxifen PCT

Nolvadex is a brand name for Tamoxifen which is also a SERM. It has been approved for use in the United States since 1962 and is prescribed to treat breast cancer, infertility and also a treatment to prevent gyno. In same way as Clomid, Nolvadex blocks estrogen from interacting with the pituitary gland. When estrogen interacts with the pituitary gland, less luteinizing hormone (LH) and follicle-stimulating hormone (FSH) are produced. Leading to a decrease in testosterone.

Nolvadex PCT Dosage 

Nolvadex is usually taken during PCT at 40mg per day for the first 2 weeks and 20mg per day for weeks 3 and 4. It is not as harsh as Clomid and because of this the side effects are less likely and if they do occur more likely to be less harsh. Having said that nausea and headaches can still occur.


HCG is short for Human Chorionic Gondatropin hormone which produced by cells that surround a growing embryo. HCG helps reverse the negative-feedback loops that the body uses to shut down its own testosterone production whilst cycling anabolics. HCG has been proven to restore testicular size as well as normal testosterone production by mimicking LH and triggering the production and release of testosterone. However, using it for too long can turn off your body’s natural process to make LH forever. HCG isn’t normally used on its own and commonly used alongside Nolva or Clomid.

HCG PCT Dosage 

500-1000iu per day is the usual dosage for 2-8 weeks. Some bodybuilders also use it during cycle at 500iu per day or 2000iu every other day.

What are the different types of legal PCT supplements?

Legal PCT’s can be highly effective for some of the less suppressive cycles. For example, a legal supplement PCT protocol can be good enough following a sensible LGD or Ostarine SARM cycles. But they are not powerful enough to combat months long steroid cycles. 

Legal PCT ingredients can be mainly split into two categories; Testosterone Boosters and estrogen blockers.  

Testosterone boosters are there to help boost natural testosterone back to normal levels for all the reasons mentioned earlier. There is a huge amount of testosterone boosters available, but the most effective ones contain these ingredients and importantly at these correct dosages. Check them out below ⤵️

  • D-aspartic Acid (DAA) – 3,000mg (3g) per day 
  • Bulbine Natalensis – 1,000mg (1g) per day 
  • KSM-66 – 750 – 1250mg (0.75-1.25g) per day 
  • Vitamin D3 – 3300iU per day  
  • Fenugreek Extract – 500mg (0.5g)

The most effective legal anti estrogen, an extremely underrated supplement in general, is Arimistane.

Arimistane is a powerful AI that decreases circulating levels of estrogen in the body. Some studies have shown it will even lower cortisol levels too. Arimistane is a suicidal AI, which prevents the conversion of testosterone to estrogen. It does this by binding to the aromatase enzyme and does so with a binding rate of .22 micromolar which is far stronger than ATD and 6-oxo which are alternatives to Arimistane. Once it binds, it is incapable of releasing until the body eliminates the enzyme from the body. 

A dosage of 75mg per day is a common PCT dosage.
