The original brand name of oxandrolone was Anavar, which was marketed in the United States and the Netherlands .   This product was eventually discontinued and replaced in the United States with a new product named Oxandrin, which is the sole remaining brand name for oxandrolone in the United States.   Oxandrolone has also been sold under the brand names Antitriol ( Spain ), Anatrophill ( France ), Lipidex ( Brazil ), Lonavar ( Argentina , Australia , Italy ), Protivar, and Vasorome ( Japan ) among others.     Additional brand names exist for products that are manufactured for the steroid black market. 
No stacks, not yet- here's the problem- you throw anavar and HGH together, never used either of them before, and now you're getting a weird side effect... You can't remedy the side effect because you don't know which compound is causing it. I would highly suggest running each first to see how it effects your body.. Start with anavar. Next cycle, you could choose to run var and add HGH for long term, under the theory that if you encounter a nasty side effect, you'll know that it's from the HGH and not the anavar because you ran it previously with no issues.
There are possible side effects of Anavar, but with confidence we can call this one of the most side effect friendly anabolic steroids of all time. In fact, with proper use many adults will be able to supplement without the first problem. To get the ball rolling, estrogenic side effects are impossible with this steroid as it does not aromatize. This makes water retention and gynecomastia impossible with Anavar. It also means blood pressure will more than likely be controlled as heavy excess water retention is the number one cause of high blood pressure among anabolic steroid users.
