Stacking and Use:
Winstrol is best used at a rate of 50 mg a day. When in an injection that amounts to a single injection every day around the same time. In orals, that'll be at least 5 tabs of a legit product.
In a mass stack Winny makes a good match for Deca and Nilevar. Whether or not its anti-progestagenic effects are for real or not, lets just say it can't hurt. In any stack with Deca the use of 25-50 mg a day for the first 6-8 weeks of the stack can kickstart it and add some strength. With Nilevar there is a practical objection because it is also 17-alpha alkylated and more toxic than Winny, so your stack would be limited to 6 weeks, which is not overly productive.
Androstenedione: The test sensitivity for anabolic steroids in the standard LGC supplement screen is 10 ng/g (10 ppb). Androstenedione is known to be naturally present in milk and milk-derived products. The concentrations of androstenedione found in milk are variable, but are typically in the low ng/ml (low ppb) region. One reference cites values of around ng/ml. For this reason, the presence of androstenedione in milk or milk-derived supplement products and/or supplement ingredients analyzed using the standard LGC supplement screen is not reported unless the concentration exceeds 50 ng/g (50 ppb). 4
