Superdrol is a decent anabolic steroid, but we would not call it superior or even “Super” as its marketing campaign once implied. What truly makes this steroid special was a group of men who recognized a hole in the steroid law and were able to capitalize on it, and in turn, make a nice profit. Due to the marketing and ease of purchase that existed for a long time, many athletes fell in love with this steroid, and it is a fine steroid, but there’s nothing magical or superior going on. Superdrol is a very basic anabolic steroid.
It was in late 2005 that the status of methasterone, in addition to that of four other designer steroids, as an AAS was brought to public awareness by an article published in the Washington Post .  Don Catlin of the UCLA Olympic Laboratory, who conducted the studies, noted methasterone’s similarity to drostanolone. A warning by the FDA was issued soon after to the general public as well as to the distributor, Designer Supplements LLC, for the marketing of this compound.  Methasterone was subsequently added to the World Anti-Doping Agency (WADA) list of prohibited substances in sport.  Despite all of this, methasterone has resurfaced within the supplement industry on several occasions since its banning by WADA. 
Andriol is a form of testosterone (as undecanoate) developed by Organon, a leading pharmaceutical company in the field of steroid hormones. The trick with Andriol is that the compound is orally ingested, but still bypasses the liver and is not broken by liver enzymes and it is not toxic liver. According to the producer, Andriol (which is based on castor oil and propylene glycol laurate) is absorbed through the lymphatic system. Whether this feature of Andriol or something else, testosterone undecanoate fails to produce significant weight savings consistent. On the other hand, it is not ineffective, especially if taken during the day, one capsule every 2-4 hours. Also, Andriol has virtually no side effects: even the natural testosterone production does not seem to be affected. Obviously, such frequent use is both unrealistic and in the end, it is up to the user if he / she wants to take the milder (if costly) approach and get decent gains without endangering his / her : Andriol is a very safe drug, especially in comparison to other forms of testosterone and no serious side effects are known, even if taken in large quantities. Yet it is the least known testosterone ester and some caution is still valid.
