How did you find a safe and trustworthy psilocybin supplier when you first started?

When I first got curious about microdosing, the sketchy scene honestly scared me off for a bit. Tons of unknowns and shady corners. For those who have been in this space a while: how did you vet your supplier or community before trusting it? Not asking for direct plugs (obviously) — just want to understand how people built confidence back then.
