Most people take steroids in "cycles" to avoid developing a tolerance and to give (HPTA) — the hormone production control system — time to enhance testosterone production after each use. The deluge of synthetic hormones that occurs with steroid use, however, throws your body off balance. When anabolic steroid use is stopped, the body takes a long time to return to normal testosterone levels. Aside from illness, the post-steroid user may have muscle loss and an increase in oestrogen levels.
So, to minimise these side effects, you use post cycle therapy(PCT).
When Should I Start Post Cycle Therapy?
If you're taking any medicines that decrease your natural testosterone production we recommend starting a PCT treatment after finishing a cycle. For SARMs (selective androgen receptor modulators) and pro-hormones, you can start right after you stop taking them.
Wait a week before starting PCT if you're using steroids.
What Drugs Are Used for PCT?
The drugs you'll need to complete the post-cycle therapy protocol will vary depending on your specific situation.
But we recommend following medications commonly used in PCT therapy-
Clomiphene (Clomid)
Tamoxifen (Nolvadex)
In plain English it means bringing your balls back to life. Don't forget to check lots of other threads on the topic with lots of information.

Both Arimidex (Anastrozole) and Aromasin (Exemestane) are aromatase inhibitors (AIs), which can be used when estrogen levels spike, but they’re typically more common during a cycle rather than in the main phase of PCT.
During PCT, the focus is on restarting natural testosterone production with SERMs like Clomid or Nolvadex. However, if bloodwork shows elevated estrogen post-cycle, a low-dose AI like Aromasin can be used short term to help bring things back into balance. Always best to tailor based on labs and individual response.
