A delicate product like IGF1 - there is no way Id buy it premixed. Its probably been shook to death in transport and all the large, fragile molecules that are bound together are probably destroyed. Get your cialas, antiestros...from these ancilliary companies. But get your gh and IGF lympholysed and make sure the manufacturer (ie-gensci) is reputable.
Or if people insist on being cheap with these fine products, live with the chances you take. Im not speaking of any one person/member specificly; Im just hearing alot about guys buying this stuff from your fly-by-nite chemists.
