Right now, MCT. I made a small batch with Castor oil after reading
@narta thread about the smoothness of Castor oil. No difference. Just took forever to shoot even when warmed up. Now, I love the idea of using castor oil because of all of the health benefits. So if I can get my pip issue fixed, that will be my next goal.
Though it could be a few different things such as I got my syringe filter too hot and it didn't filter right, I got my brew too hot (warmed it up to 240F on accident), put too much BA in. Fixed all of that and still seem to get pip.
Next batch is going to be GSO at the same 1/18 recipe. Also thinking about ordering from a legitimate domestic vendor to see if theirs gives me pip too. That would tell me if it is me or if its my dope.
