The main negative effects of the b/c are the increase in SHBG (which will bind free androgens/anavar) and stop them interracting with the receptors. The increase in cortisol (most anabolics reduce cortisol so it probably cancels out the effect) and in the case of progestins, competitive binding to the androgen receptors. I think women who are using a lot of gear (big cycles, var, primo combined, etc) have so much anabolic hormone cycling around that it makes the slight increase of SHBG negligible, and the competitive binding of the progestins almost nonexistant.
When using anabolic steroids of any type or when using any best prohormones on the market , women have to make responsible use their first priority. Sadly, given that these products are largely manufactured for use by men, the amount of available information is scant. Women also have far fewer products to choose from, especially when targeting those options that have been specially formulated for them. As a result, finding an appropriate dosing schedule can sometimes be a challenging endeavor. As such, ladies should stick with products that are produced by companies that acknowledge the demand from this demographic and that go out of their way to accommodate. If a woman uses a product that is formulated for both men and women or for women alone, she’s guaranteed to have access to clear, straightforward and easy-to-implement dosing instructions.
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.
