Got a really good 1... Took 1.5ml of it in my quad last night no pip whatsoever.
I know you asked test suspension but I dont like waterbased as i dont trust them. But if you want to enjoy no pip heres a few recipes.
TNE (oil based)100mg/ml
2% BA
16% BB
15% Guaiacol
Oil carrier is 100% EO for thinness and to hold it you could get away with 50% EO but i think crashing is prob going to happen at that. It has been 4days since i brewed it... No crashing at all thin as water.
