Mark Peters holds a postgraduate degree in biochemistry, with a specialization in the workings of growth hormones. It is mainly on that account that many companies involved in the manufacture of growth hormone products have invited him during their product formulation processes. It is also mainly on that account (of having both academic and industrial experience on growth hormone products) that he has come to be regarded as an authority on these matters. There are many people who won’t venture to buy or endorse any growth hormone products such as Genf20 Plus and HGHAdvanced before reading what Mark Peters has to say about the products under consideration.
