Tamoxifen Citrate

This Post is also available in: German

Since most steroids are more or less strongly aromatized, ie a part of the respective active substance is converted into estrogens, there can be a significant increase in the estrogen level in male bodybuilders. This can lead to a growth of the mammary glands (gynecomastia) and an increased fat intake.
A first sign of a possible gynecomastia is slight pain when touching the nipples.

Antiestrogen Tamoxifen Citrate counteracts by blocking the estrogen receptors of the affected body tissue and thus preventing estrogen and receptor binding. It is important to understand that tamoxifen citrate does not prevent aromatization, but is exclusively an estrogen antagonist. This property has the disadvantage that, after settling, a rebound effect can occur, i.e. The suddenly released estrogen receptors can absorb the estrogen accumulated in the blood.

Also important to know is that tamoxifen citrate works tissue-specifically, that is, in some tissues stronger than in others. It has a very strong effect, for example, in the mammary gland tissue, but very weak in the adipose tissue. For this reason tamoxifen citrate is excellently suitable for controlling gynecomastia, but can hardly do anything against the usual water and fat storage in the tissue.

In order to prevent gynecomastia, water and fat storage, aromatase inhibitors such as anastrozole (arimidex) or exemestane (aromasin) can be used to obstruct the estrogen generation from the ground up.

However, this is not always desirable, especially if the athlete is primarily concerned with muscle building, since estrogens are anabolic in themselves and an important anabolic component is inhibited by the inhibition of the formation of estrogen.

Side effects:

Drowsiness, nausea, vomiting, hot flashes, impairment of vision
Women may experience menstrual dysfunction.

Application / Dosage:

The use of tamoxifen citrate is recommended only in cases of gynecomastia. Bodybuilders report here dosages between 20-60mg per day.
After the symptoms have subsided, the dosage will be reduced to 10 mg per day and further taken 1-2 weeks to prevent a rebound.

The dosage information given here is not intended as a dosage recommendation or medical advice. These are statements by bodybuilders who have used or used these active ingredients. The dosages should never be regarded as generally valid. If you are using the idea of using steroids or similar, ask a doctor or pharmacist.

Black market prices / availability:

Tamoxifen citrate costs usually between 0.50 and 1.00 Euro per 20mg tablet, prescription, can be bought in pharmacies.
