My wife's 2nd run with gear was winstrol. She did really well with Var, so we decided to try winny to see how she would do with that. I got her 200 2.5mg tabs, and worked her up slowly to 15mg/day. Noticed that she didn't get the fullness like she did with the Var, but she got pretty veiny and muscular. Her sex drive was a lot higher than with Var, and her voice changed slightly. The last month of her 3 month run, her joints began to ache. Also, her period stopped. We decide that Var was a better choice, however she did use winny two more times for 30 days as part of her precontest stack. I doubt you have 2.5mg tabs as GC only does 10mg, so I guess you'll have to start with that. I wouldn't recommend jumping to 20mg, but you'll just have see what her results/sides are at 10mg before making that decision.
