When in the early eighties of the last century it became known that recombinant HGH would become available on the market, the expectations of athletes were high. Dan Duchaine had in his book Underground Steroids written an attractive description of the progress that could be achieved with recombinant human growth hormone (rhGH). No steroids were able to match that. This was also pretty much the general belief. Understandably, the release of the biosynthetic form of this hormone was eagerly awaited.
Ok, human growth hormone was already circulating on the [black] market, but that was hGH from the pituitary glands of deceased donors, also called cadaveric hGH. Now the real, identical biosynthetic growth hormone would be made available. Although the donor hGH is also identical, it has to be of course, but from the new recombinant product was expected a lot more.
