In light of Roach's revelations regarding Ariza, some posters here think that it is not possible to dope by drinking shakes. Not only are there many orally available steroids on the market (Andriol, testosterone undecanoate http://www.ncbi.nlm.nih.gov/pubmed/17371478) someone who wanted to dope would also prefer to take steroids orally because they have a shorter half-life. Orally available testosterone can have a half life from 1 hour to 8 hours. So if someone was to be tested, they could drink something on day 1. their testosterone levels would go through the roof, but 16 hours later it would be undetectable.
