@stevepep is spot on. It's less about what everyone else likes and more about what helps towards the goals you want to achieve. Research your goals and which peptides apply. The vendor listings here are great, but the people in this group are your best research tool. I'm fairly new to peptides myself and I've learned far more than I expected to just by reading threads here. The search function is great for finding specific things that you have questions on too. Best of luck to you on your journey!
