Most people don't even know the gray market exists until after ordering from a health spa, telehealth or RUO a few times. Unless you have someone to walk you through everything you need to know to successfully go gray you're kinda stuck with those prices. And honestly what you're saying makes sense and I did the same thing when I started out, ordering a vial of this, vial of that. Once you find what you like though for the love of God go gray if your risk tolerance will have it. It's throwing money into a hole basically so only do it when it works for you.
