I think doing lowcarb with gear is just a waste of gear. Why would you waste gear? What has it done to you? Nothing, and yet you treat it like some skanky ho. Oxandrolone is no skanky ho.
In order to build muscle, it helps to have insulin. Carbs get your body's insulin pumpin'. Low carbs stop it, or limit it greatly. Good for fatloss, but not good for muscle. On gear, you don't really have to worry about getting too fat, assuming your diet is decent.
Figure out what you want to do, and focus on that. If you want to add muscle, add muscle. If you want to lose fat, lose fat. You aren't helping yourself doing both at the same time. Gear helps, but it's not some magical pixie dust. Well, maybe you can do that with trenbolone. Well, ok, you CAN do it with trenbolone. But that's about it.
Hell, if you main goal is to drop bodyfat, do dnp. If you want moderate muscle increase with a 'slight' loss of bodyfat, do the ox. But don't treat your precious oxandrolone like some 2 bit skanky-ho. That just ain't right.
