Drugs can be added and removed from this list by WADA annually, although not all of the banned substances are explicitly named. Caroline Hatton, PhD , a sports anti-doping science consultant, told in a Mar. 12, 2010 email that "A key concept in prohibited lists is that they avoid being finite. Instead of listing all banned drugs one by one, they list entire drug classes and name drugs merely as examples. This is to keep users who took designer drugs from claiming that they didn't break the rules because the drugs they took weren't listed."
Halotestex Tablets are not grandly popular among performance enhancing athletes due to the simple reason that it only brings a few beneficial traits for most individuals which is not worth taking a risk for a compound like halotestin whose risks far outweigh the rewards. There are many more other steroids with almost similar and more benefits having less side-effects. However, it can be used by the competitive athlete or bodybuilder for enhancing aggression and push that is sometimes required to complete a brutal contest diet. Having said that, still one needs to use halotestin with utmost caution and not forget its long-term effects.
