Rh 883 F. 3d, at 1094. But even after all that, we conclude Mr. Bucklew has failed for two independent reasons to present a triable question on the viability of nitrogen hypoxia as an alternative to the State’s lethal injection protocol.

First, an inmate must show that his proposed alternative method is not just theoretically “‘feasible’” but also “‘readily implemented.’” Glossip, 576 U. S., at ___–___ (slip op., at 12–13). This means the inmate’s proposal must be sufficiently detailed to permit a finding that the State could carry it out “relatively easily and reasonably quickly.” McGehee v. Hutchinson, 854 F. 3d 488, 493 (CA8 2017); Arthur v. ''Commissioner, Ala. Dept. of Corrections'', 840 F. 3d 1268, 1300 (CA11 2016). Mr. Bucklew’s bare-bones proposal falls well short of that standard. He has presented no evidence on essential questions like how nitrogen gas should be administered (using a gas chamber, a tent, a hood, a mask, or some other delivery device); in what concentration (pure nitrogen or some mixture of gases); how quickly and for how long it should be introduced; or how the State might ensure the safety of the execution team, including protecting them against the risk of gas leaks. Instead of presenting the State with a readily implemented alternative method, Mr. Bucklew (and the principal dissent) point to reports from correctional authorities in other States indicating that additional study is needed to develop a protocol for execution by nitrogen hypoxia. See App. 697 (Oklahoma grand jury report recommending that the State “retain experts” and conduct “further research” to “determine how to carry out the sentence of death by this method”); id., at 736 (report of Louisiana Dept. of Public Safety & Corrections stating that “[r]esearch… is ongoing” to develop a nitrogen hypoxia protocol). That is a proposal for more research, not the readily implemented alternative that Baze and Glossip require.
