Steroids for women are like a boy going thru puberty. Expect the voice change, and no there's nothing you can do about it. Further, the more you use both in amount and over time will contribute. Generally sides reduce as the compound clears the system, so pay attention to the detection time on your compound. It can be several months in some cases.
For Primo, expect hairloss. As soon as you start a primo cycle, get some Nizoral shampoo (1% is available in most stores near the dandruff shampoo, or 1% or 2% are available online.) Another alternative is Nioxin.
For the previous poster, why a deca + proviron cycle? That sounds like a guy's cycle and personally speaking, not one I'd recommend for a woman.
