It will then mostly be working to produce estrogen. muscle mag Steroid danger. To obtain the 50% reduction we had before, then the amount of inhibitor would also have to be increased 10 times. To be really effective, the inhibitor must either be present in higher concentration than the normal substrate, or must bind more tightly. With Cytadren or Proviron, it takes quite a lot of inhibitor to outcompete high testosterone levels. muscle mag Steroid-testing. With Arimidex, rather little, even 1 mg/day, can be sufficient because it binds so strongly. The other general approach is estrogen receptor antagonism. If a molecule binds strongly to a hormone receptor, but does not activate that receptor and makes it unresponsive to the normal hormone, then it is a receptor antagonist. muscle mag Negative effects of anabolic steroids. Clomid (clomiphene) and Nolvadex (tamoxifen) follow this approach. These drugs are very similar structurally. They are both what are called triphenylethylenes, and are not steroids. The differences are relatively minor, but seem to affect an important characteristic of these compounds: drug metabolism. Both tamoxifen and clomiphene are metabolized to other related compounds which can be estrogenic or anti-estrogenic. Both act as estrogens in bone tissue, perhaps after metabolism, which is a very useful property for female patients, for whom these drugs are usually intended. (Otherwise, an anti-estrogen could lead to osteoporosis. ) Tamoxifen seems particularly prone to acting as an estrogen in the liver, which may account for reduced IGF-1 levels seen when this drug is taken. Users generally seem to agree that when tamoxifen is used, gains are a little less than what otherwise would be expected. (Let's not take this too far though: many people have made great gains while using tamoxifen as an anti-estrogen. And it's always hard to say what "would" have been the case if a drug had not been included. ) I've heard nothing but good about clomiphene, though. Proviron, an anabolic steroid, is particularly interesting. I suspect that it not only acts as an antiaromatase but in an unknown DHT-like anti-estrogenic manner.
