Halo25 was first introduced during the 1960's-70's olympics, during this time the East German Team utilised this compound on its original name Turinabol to dominate the competition. Halodrol is a 17aa steroid that converts to the steroid oral Turinabol after interaction with 3b-HSD at an estimated rate of about 5%.
Because of this low conversion, doses must be higher than other 17aa pro-steroids. However, it is suspected that Halodrol has decent potency without conversion as good results are seen despite the relatively low conversion to Turinabol. Based on Vida’s data Halodrol appears to be about as potent as testosterone, and significantly less androgenic.
"We are aware of the financial complexities of the huge expenses for R & D with respect to the small number of patients or the market system that enables these advances to become reality. Yet -- notwithstanding all your patient support programs -- it is at best unseemly for Vertex to charge our patients’ insurance plans (including strapped state medical assistance plans), $294,000 annually for two pills a day (a 10-fold increase in a typical patient's total drug costs). This action could appear to be leveraging pain and suffering into huge financial gain for speculators, some of whom were your top executives who reportedly made millions of dollars in a single day (Boston Globe, May 29)."
