I'm trying to make sure my shatter is purged correctly and get all the unnecessary waxes out that may cause health damage. Either way if they serve no benefit I don't want them in my system. With dispensary bought shatter, what can I do anything to it to make it cleaner? I read about winterizing, is that something I can do? I'm still confused on the process, but people make it seem like ti is very easy. any and all recommendations welcome! BTW I buy TC Labs (Denver) concentrates, usually their shatter. Anyone try it? it seems high quality to me, no bubbles, very transparent, not the cheapest either. What's your take? Thanks!
