Post Cycle Therapy

Guy lifting Weight PlateMany people use Post Cycle Therapy or post cycle treatment after a cycle of prohormones or prosteroids. This article will discuss the current popular beliefs in post cycle therapy, supplements you can take to enhance your post cycle experience and also some common misconceptions about being “on cycle”. With this guide you can rest assured that you will get the absolute best post cycle information to use after your cycle of steroids or prohormones.


Shut down is the slang name for the sensation that occurs when your body senses that you are over loading it with androgens. Your testicles work on a messenger system that starts at your brain, which signals the testicles to make androgens like testosterone. The tissue known as the pituitary is constantly sampling your blood and looking for estrogen and DHT, both a by product of testosterone production. The pituitary is always sending out a signal to make testosterone. If the body has too little estrogen or DHT it will send more signal to the testicles to make testosterone. This testosterone is converted to both estrogen and DHT, which will raise the levels in the blood. When the pituitary senses the levels have reached optimal, then it stops sending the extra signal.

If the body has too much androgen or estrogen, the same gland will see this and stop sending the production signal at all which will temporarily shut down the testicles. When you are introducing extra “androgen” into the blood “on cycle” the signal from the pituitary will stop completely causing the testicles to shrink for that time period.  This “shrinking” of your balls is why the myth that steroids will shrink your penis originated. Steroids will not shrink nor enlarge your penis, only your balls. So, please clear that misconception up.

Purchase Prohormones

Ironically, this “shut down” effect may actually be a good thing. The testicles are like an engine and by running them constantly you tend to burn them out faster as an adult.  The periodic shut down may actually help you keep your testosterone levels higher as you get older because you have not burned out your testicles.


The normal route for post cycle is to take an anti-estrogen like ATD in hopes that you will get faster recovery. Also people may take a SERM like Nolvadex to lower the estrogen levels in the pituitary.  The major problem is that all this accomplishes is to send more signal.  Remember the testicles are like an engine and the pituitary is like a gas pedal. By lowering estrogen, you are just sending out more signal, but this only works up to a point.

After a cycle, your estrogen and DHT levels are already at a low point due to the natural shut down.  So, ther is no need to “lower” them with a SERM or Aromatase Inhibitor.  The pituitary already sees that the levels are low and is sending out tons of signal.

The best approach is to increase the performance of the engine in addition to stepping on the pedal. You do that with supplements that increase the enzyme activity in the testicles. The best three supplements for this are Forskolin, Ginger Root and D-Aspartic Acid.  These three supplements will surely boost your testosterone production after a cycle. Forskolin increases cAMP levels, causing your testicles to be more efficient at making testosterone. Ginger and D-Aspartic Acid increase StAR synthesis, which is another enzyme in the testicles responsible for making androgens.  By stacking these with an anti-estrogen you get the benefit of increased signal along with a boost in testicular efficiency.

The combination is the most effective post cycle therapy protocol.  Additionally, you may want to take additional fish oil to help lower the potential blood pressure and cholesterol effects of a steroid cycle, but short term steroid or prohormone use shouldn’t have much of an effect long term as long as you have naturally low cholesterol and blood pressure levels.

    Do you know of any PCT that has these these there (Forskolin, Ginger Root and D-Aspartic Acid) supplements in them?

    • Ron B says:

      Not all of them. Form-X has DAA, Ginger. You’d probably have to buy Forskolin by itself and then add in something like Form-X to the mix to make a complete PCT.

  2. Tony says:

    Great information! Best I’ve found on the net so far.

  3. Tony says:

    Is it good to take an estrogen blocker while on a cycle or only post cycle with Forskolin, Ginger Root and D-Aspartic Acidith?

    • justin says:

      It depends on the prohormone you use. If you use a dry prohormone you do not want an estrogen blocker. If you run something wet (not many left) then yes it is a good idea.

      • KyleNile says:

        Soory, maybe off-topic but… What is the difference between a dry prohormone and wet prohormone?

        • justin says:

          Dry means it won’t add any estrogenic effects, wet means traditionally it can convert to estrogen. Remember that estrogen isn’t a bad thing it helps with side effects, fat loss and may help increase mass.

  4. Ron B says:

    PCT is way overblown. Back in the day no one even knew about post cycle therapy. Sure it’s useful but it’s not deadly if you don’t do it like so many of the bro’s tell you on the boards. Just be smart and you should recover on your own.

  5. Red says:

    Where do you get D-aspartic acid? Is one better than the other or are they all pretty much the same?

    • justin says:

      People like the Sodium D-Aspartate better than the d-aspartic acid. You can find it in bulk or in a variety of mixes. One of our sponsors has it in their product FORM-X
