Are Peptides Safe and Beginner-Friendly?

I’ve read a lot about the safety of peptides, and I’m curious are they really safe for someone who’s completely new, or is there a lot you need to know before starting? For beginners in Australia, what are the most common mistakes people make? Is it using the wrong dosage, picking the wrong type of peptide, or not following proper timing? And how do you know if your body is responding well or if something is off? Do people usually consult a professional, or is it mostly self-guided? I’ve seen mixed advice online, which makes it even more confusing. And once you figure it out, how long does it take to feel comfortable with the routine?

For people who were beginners and now have experience, what would you tell someone just starting today to make the process safer and more effective? I think having real advice from people who have gone through it is so important because there’s so much conflicting information online.
