Shipping is consistently fast usually at my door within a couple days of ordering. What really sets them apart is the COAs. Every lot has current, verifiable third-party testing posted before you even buy. That level of transparency is rare in this space and it's the reason I keep coming back. Product quality has been spot on across multiple orders. Highly recommend for anyone who actually cares about knowing what they're getting.
