IGF-1 is an extremely anabolic hormone and is proclaimed by scientists to be the critical mediator of muscle growth as it has the unique ability to stimulate both muscle cell hyperplasia (an increase in number of actual muscle cells) and muscle hypertrophy (muscle cell growth/anabolism). It also enhances muscle growth by increasing amino acid uptake and protein synthesis.

Once bodybuilders learned of these powerful anabolic effects and how IGF-1 not only increases the size of existing muscle cells, but also proliferates the formation of new muscle cells the search for a means to directly increase IGF-1 levels was on. But no effective option existed other than pharmaceutical recombinant IGF-1 injectable forms.

Now, with the development of HEXAGHEN, the amazing muscle building effects of IGF-1 are being experienced by everyone.
