This so much. I've brewed test e @ 315mg per ml and its painless. Tested bloods and scorerd well. Only time I would use GSO again is if I brewed Finaplix pellets. They do not like mct oil one bit and its a bitch to filter with it. Other than I use mct for everything even comp th pelletsI used to use gso exclusively then made the switch to mct recently and im in love. Its so smooth and pins easily. Also it holds everything like a champ.
