I started researching this subject last year which brought me to AM. Its a facinating field and I can tell you what I've gleaned from this site and whose threads and posts to look at that will save you some time. At the beginning of this forum is a sticky on IGF1, take the time to read it and it will answer alot of questions for you and get you rolling on this subject. No the GH fragment is not the equivalent of HGH, its only a part of the chain in the 191chainlink amino's that make up HGH. Thats where the Fragment part comes in. HGH is synthetic Growth Hormone. Guys that are using GHRP-6, 2 and CJC-1295 for example; are using these peptides to create natural GH pulses in thier bodies. Most of not all of them are following a protocal called "Dats Protocal" named after DatBtrue; who is in my opinion a godsend to the world of peptides. He has a thread on here that you can find by punching his name for posts or threads and its the Bible of Growth Hormones. It not only shows the science behind these peptides but he and others back it all up with mountains of medical research that they have made their lifes work. Such as the one at the beginning of this forum by cosmo and grunt. Trust me; find the thread; its a must read and will answer every question you have including dosing schedules ect. The other post or thread I would recommend is Papaspumped. Papa did a six months study on his rat and posted daily results for everyone. I've read it twice and everytime I have a question I just go back to it. Papa also put together an excel calculator to help guys with their dosing,bacwater, AA, ect. As for the companies, yes there are companies to avoid but its againts forum rules to discuss those things and could get you banned; which is why no one will touch that question. If you have any other questions dont hesitate to ask guys like Trippdog, bobslaw,grunt, rhyno ect.. but if you havent done your homework, they're not going to spend alot of time on you. Trust me, I've asked enough stupid questions to fill a whole forum. Finally I just took there advice and started reading; alot. But I got my answers.
