There are approximately 750,000 wild caribou in Alaska (including some herds that are shared by Alaska and Canada's Yukon Territory). The largest herds (as of 2011) are the Western Arctic Herd at about 325,000, the Porcupine Caribou Herd at about 169,000, the Central Arctic Herd at 67,000, the Fortymile Herd at 52,000 and the Teshekpuk Herd at about 55,000. Caribou are somewhat cyclic in number, and the timing of declines and increases, and the size to which herds grow is not very predictable. Although overhunting caused some herds to remain low in the past, today, varying weather patterns (climate), population density, predation by wolves and grizzly bears, and disease outbreaks determine whether most herds increase or decrease.

Although Anavar has low side effects but when combined with other steroids chances are that harmful effects may occur. For instance Anavar itself does not aromatize but when stacked with testosterone based esters like propionate or Cypionate estrogen activity can occur. This estrogenic activity can be controlled by taking anti-estrogenic drugs. Similarly if an oral steroid is taken along with Anavar then the liver function should be monitored through liver function tests and precautionary medicine prescribed by the physician should be taken.
