TweetPeps are great, especially if you either can't afford, or don't want to spend what good hgh costs. They have several benefits you won't get from ghost though, as well. They are great for keeping your appetite up(or making your appetite greater, to begin with...). Basically, you should decide exactly what you want from the peptides and choose the ones that will accomplish those goals(they all have slightly different properties, as aas do... so choose the ones for your specific goals in mind.).... there are several people on here that are more knowledgeable than I am, with peptides... Pittsburgh 63 and vibrant are both very knowledgeable with peptides and could help you choose the ones that will work to help accomplish your goals the best.
