Many peptides are for research use only. Not for human use. If you consume research chemicals you might become Spiderman or you might become dead. No one knows hence they're not approved for human use. This is some information but if you use it on humans you're really on your own. Doctors definitely learn things in Medical school and you skipping that might be really bad for you. Information is cool, assuming you know things that you don't isn't. Get a prescription from an actual doctor before you take chemicals.
