Bioelectrical impedance analysis (often referred to as “BIA”) is an accurate method of estimating body cell mass. Instruments for reliable measurements of body composition are commercially available (., BIA Quantum; RJL Systems, Inc., Detroit). These devices can be used quickly in the office ( Figure 1 ) ; a minimum of staff training is required. Bioelectrical impedance analysis provides an estimate of the total body water by measuring changes in a low electrical current passed between electrodes placed on the upper and lower extremities. The sizes of other body compartments (including body cell mass) are then calculated using equations based on assumptions about the relationships between different body compartments and total body water. The validity and reliability of the results depend heavily on several factors, including correct placement of the electrodes, “normality” of body habitus, hydration status and the equations used to estimate body cell mass. 10
The oral use of stanozolol can also have a profound impact on levels of SHBG (sex hormone-binding globulin). This is a characteristic of all anabolic/androgenic steroids, however its potency and form of administration make Stanozolol particularly noteworthy in this regard. Since plasma binding proteins such as SHBG act to temporarily constrain steroid hormones from exerting activity, this effect would provide a greater percentage of free (unbound) steroid hormone in the body. This may amount to an effective mechanism in which stanozolol could increase the potency of a concurrently used steroid. To further this purpose one could also addition Proviron, which has an extremely high affinity for SHBG. This affinity may cause Proviron to displace other weaker substrates for SHBG (such as testosterone), another mechanism in which the free hormone level may be increased. Adding Stanozolol and Proviron to your next testosterone cycle may therefore prove very useful,, markedly enhancing the free state of this potent muscle building androgen.
