Why this tier: A stabilized glucosamine sulfate salt (plain glucosamine sulfate is hygroscopic and needs a stabilizing counter-ion -- historically NaCl in the "Rotta" preparation used in the positive European trials; 2KCl is a common commercial alternative). Evidence for sulfate broadly may reasonably extend here, but no dedicated head-to-head RCT of the 2KCl salt specifically was found -- equivalence is an assumption, not a demonstrated fact.
Source: none (no dedicated RCT of the 2KCl salt identified)
