Per 
SCP-5502 the undying werewolf
SCP-5502s containment procedure is to be contained by tungsten steel being attached to the arms and legs of it, weighing it down.
SCP-5502’s description is a large werewolf, it is approximately 10’6”, in recent tests it’s regenerative abilities aren’t the best in the foundation ( that credit goes to SCP-682 ) or the weakest but is still quite strong, during a containment breach concerning other SCPs, SCP-5502 managed to escape the tungsten steel constraints, killing ten guards in the process before being knocked out bye SCP-939s AMN-C227 and then being dragged back to its containment cell after the breach was ended.
In other tests not concerning strength but smarts, it turns out to be that SCP-5502 is sentient but only puts its smarts to hunting prey before being captured bye the SCP foundation, before the still ongoing silence of SCP-5502, it said a small amount of its origin, but then being asked about a piece of what we know about SCP-5502 which that question was [REDACTED].
