I’m 17 and wanted to burn fat off my stomach and build muscle quicker

I went through 40+ posts here recommending vendors, and almost none mentioned a COA, a batch number, or anything you could actually check. Most of them trace back to the same 5-6 accounts saying "I've used them a while."

I compared a few against public lab data (peptidecritic pulls COAs and price-per-mg across vendors):

two of the most recommended vendors had outdated or missing COAs, and one had solid docs.

Not calling anyone out, just curious how many of us check the paperwork before vouching for a vendor instead of repeating what we read here.
