Teslac belongs to the group of sex hormones and from a biochemical perspective, is a relative of the
testosterones. Although this catego-rizes it as an androgenic steroid, from a technical point of view it is neither
an androgenic nor an anabolic steroid. Teslac is very similar to the structure of androgenic steroids but it has
only a very low androgenic and no anabolic effect. In school medicine this compound is used in the treatment
of advanced mammary carcinomas in women. Before you discard Teslac as a completely useless drug and
stop reading we want to tell you that Teslac does have his justified application in bodybuilding. Two reasons
speak for an intake of Teslac: First, it is the most effective antiestrogen and second, it causes a distinct
increase of the endogenic (body's own) testosterone production. Teslac is unique in its effectiveness as an
Like Proviron, it prevents the aromatizing process of the steroids from the basis. Thus, Teslac
prevents almost completely the introduction of more estrogens into the blood and subsequent bonding with the
estrogen receptors. Athletes who want to be absolutely certain combine Teslac with Proviron 50 mg/day and
obtain a complete sup-pression of the estrogens. What makes Teslac different from Proviron, however, and so
desirable is the characteristic that it can lead to an irreversible and permanent suppression of the estrogens in
male ath-letes. Studies, in the meantime, have proven that Teslac makes male athletes resistant to an
aromatization of steroids over a prolonged period. A water retention caused by the estrogens and
gynecomastia is thus avoided in the long term.
Another advantage of Teslac is that it directly influences the
hypothalamus and upon its "signal" the hypophysis releases more gonadotropine, leading to a significant
increase of the endogenic testosterone level. The strength of the testosterone-stimulating effect of Teslac can
be compared with the one of HCG (see also HCG). Unlike HCG which after only a few-hours results in an
elevated plasmatestosterone level, Teslac does require a longer initial period. Thus a regular intake over
several days is a preliminary. Although we have initially mentioned that Teslac does not have an anabolic
effect, based on the increased testosterone level, a gain in muscles and strength can occur. This could lead to
androgenically linked side effects but they are very unlikely.
Side effects from Teslac are very rare. Since this compound, above all, was developed for women, it was
extremely important to exclude the androgenic effect component as much as possible. This was successfully
accomplished so that females very rarely experience masculinizing symptoms such as, for example, increased
growth of body hair or deep voice.
Possible side effects from Teslac are given on the package insert by the
German manufacturer, Bristol Arzneimittel GmbH, for the remedy Fludestrin: "cutaneous eruptions
(maculopapular erythema), high blood pressure, sensations such as itching and pricking (paresthesia), pain in
the arms and legs and swelling, tongue infection, loss of appetite, nausea and vomiting." These side effects,
as already mentioned, are extremely rare. The plasma calcium level of athletes should, however, be checked
since Teslac could lead to hypercalcemia (increased calcium level).
Perhaps the greatest negative side effect of Teslac is its high price. A package of fifty 50 mg tablets costs
about $200 on the black market. Every single tablet thus costs $4. The recommended daily dose of 10-20
tablets that is 500-1000 mg/day! Usually 4-5 tablets daily (200-250 mg/day) are sufficient. However even such
a dosage will discourage most athletes because of the high cost. An alternative would be to limit the intake of
Teslac to two tablets per day and to supplement them with the similarly effective Proviron (50 mg/ day).
