DUDE, please don't take 100mg oxandrolone a day. Why would you take this much if you were worried that Deca would be so unhealthy that your arteries would corrode?
Go on a sane cycle of test, low dose deca & low orals. ie 500mg test, 200mg deca, 30mg anavar.
Much better than taking mega doses of orals in terms of gains, health & lower sides.
