I had NDE from TGC and it was alright but not anything close to the reported potency. I have some from LF/BJC that I got as a sample but I haven't tried it to compare cus I prefer their protopyne. But Im sure it's the same. LF is legit and I've been using them for years. It has poor solubility in water so I used PG to make a solution for direct ROAs. This would also work for making a vape juice if you add VG or just use PG by itself and use a glass bubble(meth pipe) to measure out accurate individual doses. If you use a vape don't use anything with exposed coils cus you'll get residue build up over time that can result in the "puff of death" you hear about sometimes. That was a whole deal back when iso first came out years back. You need the quartz bowls they sell for THC vapes for shatter and concentrates. All zenes vape differently as powders. It's best to mix them with a buffer to act as a cut and a carrier. It's not ideal to be eyeballing doses of pure powder anyway. Only a couple zene powders vaped very well. Etazene was the best. But most burn quickly and are unpleasant. Use mannitol or erythritol to make a usable powder mix. There are ways to do that and avoid hotspots and get even distribution throughout. But volumetric dosing is the most accurate and safest way to deal with high potency substances. So I suggest you just do that. Good luck.
