A legitimate, transparent new entrant with strong independent Bioviridian purity numbers and a real named LLC, but its ceiling is capped by a ~6-month history, single card-only rail, non-clickable on-site COA links, and self-admitted partial testing coverage. Promising but unproven; reassess as it matures.
