I am currently using Pharmacom 300 Test E. I think the carrier is grapeseed oil. Its good quality gear , but its extremely hard to push through my normal setup which consists of a 3mm Syringe and a 25G Needle, whereas other UGL oils have been easy to push through using the same setup
I have to heat it up with a blowdryer for about 45 seconds first, that makes it a little easier to push.
Its pretty annoying to the point where I am going with a different UGL next time.
