I haven’t tried the shatter yet. but i’ve tried 100% D9, 100% live resin and 50/50. My personal favourite for safety mixed with potency is the 50/50. gives me a strong hit from the d9 and then a very nice body and head high from resin. it’s a nice smooth slow start but comes on heavy later. live resin and the 50/50 is closer to real bud and d9 is the more potent thc concentrated part. so overall, with the prices 50/50 is the fav, cheap safe, tasty and great high.

in terms of actual safety and ‘clean’ there’s not much difference in them all. it’s very much down to the vendor not the different types. MJ is a safe vendor imo so you will have no issue with any. i’d recommend doing more research or maybe trial 1 each and then decide!
