It depends a bit on what type of information you are looking for. If you want the hard science, and what has been tested and proven in human clinical trials, you end up with a very short list of peptides and you really need to read the scientific papers, though chatgpt in research/scholar mode is pretty good.
If you want a big list of all the peptides and what some people claim they do, with very variable amounts of actual science behind the claims , there are lots of them, but most are either from sites aiming to sell peptides, or by those who have bought into the whole idea and often make claims about what they do that goes well beyond what is known or proven. The biggest problem by far is when people claim a peptide does something and present evidence for it , but fail to mention or emphasise that the science is from cell or animal studies not human ones, and may or may not apply to humans, and mostly gives the false impression that effects are known and predictable, and safe.
And reading many different pieces of information saying the same thing indifferent places, tends to be very convincing that it must be true, and again gives a false sense that the effects of these peptides are known and safe, when most of the time human testing has not been done at all, so more or less by definition they cannot be considered safe.
GLP drugs do not really fall into this category, some of the newest ones have not fully completed human testing , but still have usually a lot of solid clinical trial data, and the older GLPs are very well understood and tested. This does not mean they cannot cause side effects or problems, but at least the research has been done, and the older ones are proven to be safe enough to use as drugs in medicine.
