I was contemplating doing this in Test U.I did TU 300 I think at 2/30 or maybe 2/35 in castor oil for that super extended half life. Test D is superior for anything other than "month long vacation" type brews.
I may just go for a 1/40 castor mix
IF you feel that would hold at 300mg, I will go for it
