Bro there are so many factors that you have to consider.Diet,genetics,AAS,etc..some don't even respond that well to peps or GH.I would definitely do some research before you commit to anything.Read through Dat's thread and it will answer all questions that you may have.And it is more beneficial to add a GNRH such as CJC or Mod. Grf 1-29 to the ghrp of your choice.All research sources on this board are legit.
