Gyno is caused by a raise in prolactin levels. This can be caused by a either a raise in estrogen levels or a raise in progesterone levels in a male. Progesterone increasing to levels causing a large enough raise in prolactin is actually very rare, and usually only happens with high doses of Deca (usually above 800mg to a gram per week) or large daily doses of Tren. Although some may experience problems at lower levels of these
steroids, it is doubtful. Some think winstrol can control progesterone, but its unfounded and probably more wishful thinking than anything. You probably stand a better chance using Nolvadex to control progesterone than winnie, but there is no proof either can actually stop progesterone uptake at a celulear level. If you think you might be getting gyno that is caused by Deca or Tren, stop using it and go see an endocrinologist. They can take your prolactin, estrogen and progestin levels and tell you WTF is going on. Later
