I have tried to use the search function so sorry if this is redundant but I am looking at buying Tirz from this vendor. I previously used ASC and Tuk and everything tested great. I posted about it here. https://glp1forum.com/threads/thanks-from-a-newbie.1795/ Ava has been responsive but I can't find any reliable reviews. I will test either way but would like to avoid a problem beforehand if possible. Thanks
