I started a few months ago and was on the same boat. I found a few forums and then this youtube channel helped me understand the very basics.

Once I saw that video, and the rest of theirs, I downloaded a few documents to read - my favorite is called "Peptide Encyclopedia" - I still use it for reference. I attached it.
When I figured out which peps caught my attention, I goodled everything I could and then stumbled upon this forum (and others). I used the search feature here for more info and anectdotal experiences.
After having made some overpriced purchases from domestic resellers (before this forum), I decided to take the plunge and learn crypto to order from the sellers here.
Good luck on your pep journey!
