Is this a havoc pulse, or a straight cycle? GLCD is a proprietary blend of a few different things(6-bromo,ketosterones extract from cissus,forsklin extracts,DVTHF), so its tough to know exactly how much cissus is in there. I you're looking for good overall joint support i'd go with Palo Alto's "Incarnate" or Usp's "Super Cissus"
