KO - sexual sides are possible. You could run a small amount of test with the oxandrolone, Just to keep levels kinda "baseline" - like 100-200 mg's of a long acting ester every 7-10 days. Have run a couple of ox cycles like this and it works great. Not enough test to have to worry about estrogen suppression or sides, but keeps some test in the system. Ox is great man - enjoy!
