Stanozolol is not a fat burning drug. It's an anabolic compound with very low angrogenic properties thus making it ideal for a cutting cycle. It doesn't lead to water retention or aromitization to any measurable degree, so it will not have the negative estrogenic effect of agonizing alpha-adrenergic receptors. Your cycle is fine without the winny. Adding it may increase anabolism depending on your level of use, training, and genetics, but it won't stimulate fat loss. If you do decide to run it it should be taken every day. Three times a week would be a waste as the drug will only be in your system for a short period of time over the course of the week. The half-life is short so it needs to be consistantly and frequently readministered into the body to maintain it's anabolic effects.
