Cyclofenil is not an anabolic/androgenic steroid. Cyclofenil works as an antiestrogen and, at the same
time, increases the body's own testosterone production. Since Cyclofenil itself is only a very weak and
mild estrogen it occupies, the estrogen receptors, and prevents the stronger estrogens from bonding
with the receptors thereby becoming active. As a matter of fact, this works so well that some athletes
take Cyclofenil during the steroid treatment in order to maintain a low estrogen level. The result is a
lower water retention produced by the steroids and less gynecomastia. The athlete has a harder
appearance, making this is a compound that can potentially be taken during the preparation for a
competition. Bodybuilders, however, use it less frequently since they prefer the more readily available
Nolvadex and Proviron compounds.
Based on our experience, the dosage lies be-tween 400 and 600 mg/day. Lower dosages usually do
not show satisfying results. Cyclofenil, for this purpose, is either used during steroid treatment, after
the treatment, before competitions with doping tests, or by "natural bodybuilders". Like HCG and
Clomid, Cyclofenil is ineffective in women since it has a positive influence on the male hormone
system. Even in men, the increased testosterone level attributed to the effect of Cyclofenil is not high
enough to speak of drastic improvements; however, strength gains, a slight gain in body weight, a
noticeable increase in energy, and a higher regeneration are possible. These results are noticeable
particularly in advanced athletes who have little or no experience with steroids. Cyclofenil needs a
response time of approximately one week before it becomes effective.
In a few cases athletes experience a light acne, increased sexual desire, and hot flashes. The first two
secondary symptoms are especially indicative that the compound is actually effective. After
discontinuance some athletes report a depressed mood and a slight decrease in physical strength.
Those who take Cyclofenil as an antiestrogen during steroid treatment could experience a rebound
effect when the compound is discontinued.
In the meantime, it is very difficult to find Cyclofenil and it is rarely found on the black market. The
Mexican Fertodur by Schering contains 16 tablets of 200 mg each which are welded into aluminum
foil with the name "Fertodur Tabletas" printed on top. Such a package costs $25-30 on the black market.
