Here is another thread where someone stated making TE-500 with no solvent. It got a lot of push back.

I found this after I made it and went through the experience that I did.
I am looking for the forum where Spidie introduced his TC/TC-500 combo. I'll let you know when I find it. Spydie (the Alchemist) has also posted some other ideas that I have tried and find amazing. Some of his ideas I've used to produce a oil-based TNE-100 that is crystal clear, flows like water and is smooth as silk. But again, another story for another time...
Incidentally, I think I tried the TE-500 (no solvent) mix after you mentioned it, in some way, somewhere else on this board. I did use 2%BA and grapeseed oil. So I don't know it that matters. I don't remember if you ever stated the type of oil you use in your mix.
I am not trying to cause an argument here. But, I do hope opposing views are ok. Balance is important. and not everything works for everybody.
