Mesterolone is an orally applicable androgen, and DHT derivative, is sold under the brand proviron, In the late 70's and early 80's Mestero lone was used with some success in controlled studies of men suffering from various forms of depression. Both the mesterolone and placebo groups improved significantly and there were no statistically significant differences between the two groups. another, 100mg mesterolone cipionate was administered twice monthly, Mesterolone is a relatively weak androgen and rarely used for replacement therapies.
Standard Proviron dosage for androgen or male fertility treatment typically ranges from 50-75 mg per day. Typically, the total dose is divided into 25 mg doses 2-3 times daily. In androgen deficiency programs, total dosage almost always starts at 75 mg per day and is slowly reduced to 25-50 mg per day based on the patients needs. In terms of performance, Proviron dosage is typically 50-150 mg per day. However, most men will find 100 mg per day to be the lowest beneficial dose, with both 100 mg and 150 mg being very effective. Total dosage usually lasts 8-12 weeks. However, when working to break through a critical point in a cycle, say at the end of a cycle, a 6-week course of Proviron will work. When you plan to use Proviron, you will find that it works well with all anabolic steroids. During the fat loss phase, it is most beneficial when used with steroids such as oxandrolone, drostanolone, and stanozolol, as well as metabolite. This will greatly boost the androgenic properties of these steroids to provide and promote a harder appearance.
