Cyclofenil

Cyclofenil is another non-steroidal ancillary drug used by athletes, similar to HCG and Clomid in action. This drug is most commonly used to increase endogenous
testosterone levels after a cycle in an attempt to avoid a hard crash while waiting for your hormone levels to naturally balance. Similar to HCG and
Clomid, cyclofenil seems to quickly and effectively raise natural levels. Anecdotally however, cyclofenil does has the reputation of being the weaker of the three.
Like Clomid, cyclofenil may also act as an anti-estrogen, binding to estrogen receptor sites and blocking out other estrogens. This is especially helpful when natural
testosterone levels are suppressed and an excess of estrogen may be present upon steroid termination. It should also be noted that some athletes have
experimented with using cyclofenil not as a post-cycle ancillary drug, but alone and solely for its anabolic properties. However, anyone familiar with anabolics
would likely be disappointed with the results cyclofenil would bring, as it is not an extremely strong product, and certainly would not work as well as anabolics.
Here in the U.S., Fertodur from Mexico is probably the most commonly imported cyclofenil product although it is produced in many other countries. Currently,
fakes should not be a problem with this product.
