I been applying igf des2,3 in my calves and qauds and all I can say is, why the fck did I wait so long. my quads and calves just look ridiculas. Veiny and pumped all day long. Put it in my chest just for shits and giggle and people at the gym were lookn at me like what the fck!!!!! I love that reaction. Can't wait to get my MC IGF. Hopefully it comes in soon...
