PCT – (from English Postcycle therapy, in translation “postcycle therapy”) – a complex of drugs and sports supplements used in bodybuilding and strength sports in order to reduce side effects and complications after a cycle of steroid hormones or. prohormones. Post-cycle therapy is especially important when taking high doses of hormones or when taking two or more anabolic drugs at the same time.
PCT literally means post-cycle therapy, but for convenience, other components have been included that have been used since the beginning of the cycle and are not formally part of PCT.
Objectives of postcyclical therapy
- The hormonal system of the body
- Restoration of the natural hormonal background – maintaining the gained muscle mass
- Combating the opposite phenomenon
- Prevention of feminization (gynecomastia).
- Prevention of testicular atrophy and oligospermia
- Prevent and reduce other side effects
The main components of PCT
Antiestrogens are divided into two classes:
Aromatase inhibitors (letrozole, anastrozole and others) – during the course block the effects of estrogen when using flavoring drugs (testosterone, sustanon, methandrostenolone and extremely mild – boldenone and fluoximesterone). Many believe that proviron is a weak aromatase inhibitor.
Estrogen receptor blockers (tamoxifen, clomiphene) or toremifene – after a course of 2-3 weeks to restore the secretion of testosterone. These drugs play a key role and are extremely important. They are used according to courses of any difficulty.
Chorionic gonadotropin – helps prevent the development of testicular atrophy and desensitization of Leydig cells. It is used for difficult courses lasting more than 6 weeks. The onset begins within 2-4 weeks of the course (or the last 3-5 weeks) and continues until the anabolic drug is removed, then there is a transition to estrogen receptor blockers.
Cabergoline (Dostinex) is an inhibitor of prolactin secretion. It is used when taking progestin drugs (nandrolone, trenbolone), which increase the level of prolactin, which is responsible for most of the side effects of these drugs. It is usually taken at a dose of 0.25 mg every 4 days during treatment.
