Information on medicinal products containing tamoxifen: everything you need to know.

Tamoxifen is a medicine whose active ingredient is tamoxifen citrate. It belongs to a class of medicines called anti-oestrogens or selective oestrogen receptor modulators (SERMs). There are many generic medicines that use the same active ingredient (e.g. Nolvadex). The price of these imported tamoxifen is often reduced.

Tamoxifen citrate has a complex mechanism of action. It can act as an oestrogen receptor antagonist or as an oestrogen receptor agonist in different tissues of the body.

In breast tissue, for example, it acts as an anti-estrogen and blocks the binding of oestrogen to the receptors. However, in other tissues of the body, such as bone tissue, it acts as an oestrogen agonist, stimulating oestrogen receptors and affecting the process of cell division. As a result, an improvement in bone density can be observed. In bodybuilding, tamoxifen is used to lower oestrogen levels and prevent negative side effects associated with taking anabolic steroids, such as skin problems and digestive disorders. It increases testosterone levels in men by up to 83% and is a very powerful anti-estrogen.

Information about medicines with the active ingredient tamoxifen:

  • ATX code: L02BA01.
  • Structural formula C32H37NO8.
  • Clinical pharmacological group refers to hormonal preparations and antineoplastic agents.

The effect of Tamoxifen depends on the particular tissue and context of use and must be prescribed and monitored by the physician to achieve the desired effect and minimise possible side effects. Based on our observations and personal experience of treatment with Tamoxifen, we have compiled a detailed article on the preparations of this active ingredient. Please note that the information given here cannot replace a consultation with a specialist – everybody is different.

Benefits and effects of tamoxifen-containing medicines

Tamoxifen-containing drugs can be used in bodybuilding, especially during or after treatment with anabolic steroids. Apart from its affordable cost, tamoxifen has other benefits and positive effects:

  • Reducing the risk of gynaecomastia. Tamoxifen works against oestrogen and can help prevent or reduce the development of gynaecomastia. Gynaecomastia is breast enlargement in men that can be a side effect of taking anabolic steroids.
  • Restoring normal testosterone levels. Tamoxifen can help restore the body’s normal testosterone levels after anabolic steroid treatment. This is done by inhibiting the negative feedback of oestrogen on the hypothalamus and pituitary gland.
  • Reducing water retention and oestrogen side effects. Tamoxifen can help reduce water retention, swelling and other side effects associated with high levels of oestrogen with anabolic steroids.
  • Protection from oestrogen-related side effects. Tamoxifen may help protect organs and tissues from oestrogen-dependent side effects, such as an enlarged prostate or increased risk of breast cancer.

It is important to note that it is important to consult a doctor before using Tamoxifen in bodybuilding. The product may have its own side effects and interactions with other medications, so it is important to consult a doctor before using it.

Scientific rationale and clinical studies on the active ingredient tamoxifen

Tamoxifen is one of the most studied medicines in the field of oncology, treatment and prevention. Below are some of the scientific rationale and clinical trial results for tamoxifen:

  • Tamoxifen has been extensively studied in clinical trials and has been shown to be effective in treating breast cancer. It can reduce the risk of recurrence in patients with oestrogen receptor-positive cancer and improve patient survival.
  • Cancer prevention. Tamoxifen has been studied as a preventive drug for women at increased risk of breast cancer. Studies have shown that tamoxifen can reduce the risk of developing a tumour.
  • Prevention of osteoporosis. Some studies have shown that tamoxifen can have a positive effect on bone density and prevent osteoporosis in postmenopausal women.
  • Anti-oestrogenic effect. Tamoxifen has an anti-estrogenic effect by blocking the action of oestrogen in various body tissues. This property makes it useful in a bodybuilding context to reduce the risk of gynaecomastia and other oestrogenic side effects of anabolic use.

Based on our observations, we can confirm the product’s effectiveness in lowering blood oestrogen levels, which is undoubtedly important for bodybuilders taking steroids.

Guidelines for the dosage and cycle of medicines containing the active ingredient tamoxifen

The duration of the dose can vary depending on the steroid cycle and individual needs. It can usually last 4 to 6 weeks or longer, depending on the doctor’s instructions. It is important to have a check-up before ordering Tamoxifen. Do not exceed the dosage and duration of use without consulting a specialist.

Here are some general recommendations:

Prevention of gynaecomastia To prevent gynaecomastia during the anabolic cycle, it is recommended to start tamoxifen at the first sign of breast enlargement or discomfort. The dosage may be 10-20 mg (0.01-0.02 grams) of tamoxifen per day.
SCT with tamoxifen After completing a course of anabolic steroids, many bodybuilders take tamoxifen in SCT to restore normal testosterone levels and reduce estrogenic side effects. Recommended concentration of the mixture may be 20-40 mg of tamoxifen per day for several weeks.

Watch out for possible side effects while taking the mixture and see your doctor if you experience any unpleasant symptoms.

Indications for the use of medicines containing the active ingredient tamoxifen

One of the most important uses of tamoxifen citrate in sports is its ability to prevent and reduce the oestrogenic side effects of anabolic steroids. Anabolic steroids can be converted to oestrogen in the body through a process known as aromatisation, which can lead to side effects such as gynaecomastia (enlarged breasts in men), water retention and high blood pressure. Tamoxifen citrate acts as an anti-estrogen by blocking the oestrogen receptors in the tissues, preventing or reducing oestrogen side effects.

Tamoxifen is also suitable for SCT. It is given after completion of anabolic steroid treatment to restore the body’s natural testosterone production. Tamoxifen citrate helps to suppress the level of oestrogen in the body and stimulates the production of the body’s own testosterone, which helps to restore hormonal balance.

The dosage should be determined by your doctor, depending on the individual patient.
