Hello hope that can get some very sought after advice. New to the forums
Used Normals tek to the T trying to freeze percip, Only got close to .1 from 100g of bark I have been researching for awhile. Tried to do several pulls but still my yeild is close to nothing if nothing.

No one?

It'll be hard to pinpoint the issue based on info you provided.

There may have been a fault in the process you did or one of the ingredients was unsuitable (solvent?). It's also possible that the raw material (preferably powdered prior to extraction) you used had little DMT to start with. No one can really know...

If you can elaborate a little bit more then I'm sure someone will try to solve the puzzle.

I'll echo this statement. Many variables.

Bark type?

I'm unfamiliar with the tek. If you elaborate - people will help.
