You mentioned a couple things that concern me here. First off, stanozolol and oxandrolone should not be taken together. They both put significant stress on the liver (especially stanozolol - that's its main downside) and if taken together can easily damage your organs in short order.
Secondly, one aspect of stanozolol that seems to be regularly overlooked is its effect on the benzo pathway. Taking stanozolol and xanax together is a bad, bad idea. At best, you'll need more xanax to get the effects. At worst, you'll wind up dependent faster than you thought and going through benzo withdrawals, especially augmented by stanozolol's effect, is no joke at all.
About the trenbelone. You're talking a heavy hitter here. This one is 500/500 anabolic/androgenic. You should probably run prop with it so your sex drive stays up. If you haven't done tren before, don't mix it with winny and anavar (stanozolol and oxandrolone). You'll be wreck, I guarantee it. Tren makes some folks mad. It's the only roid that got me off my psychological walk. Mix it with winny (which makes you mad too because of its benzo pathway activity) and you're an arrest waiting to happen. All in all I don't like what I read in the thread starter unless you are a pro bodybuilder, which you aren't or you wouldn't be asking what you're asking. My advice: Study more, lower your doses, stick to test prop and oxandrolone, stay away from the xanax. You'll come away happier in the end.
