Keep in mind I am on TRT, not cycling. With that being said, it looks like some studies indicate that oxandrolone actually increases the effects of warfarin. Not recommending an anavar cycle or anything like that, just sharing the info.

WHO Pharmaceuticals Newsletter 2004, No. 03: SAFETY OF MEDICINES: OXANDROLONE - Warning for interaction with warfarin

Ok, so in this study they used 10 and 20 mgs ED of oxandrolone, what happens if one uses normal bodybuilding dosage?

Is it viable for the OP to do multiple bloodwork to correct warfarin dosage in order to maintain PT in optimal values?
