A thermogenic is a broad term for any supplement that the manufacturer claims will cause thermogenesis , resulting in increased body temperature, increased metabolic rate, and consequently an increased rate in the burning of body fat and weight loss. Until 2004 almost every product found in this supplement category comprised the " ECA stack ": ephedrine , caffeine and aspirin . However, on February 6, 2004 the Food and Drug Administration (FDA) banned the sale of ephedra and its alkaloid , ephedrine, for use in weight loss formulas. Several manufacturers replaced the ephedra component of the "ECA" stack with bitter orange or citrus aurantium (containing synephrine ) instead of the ephedrine.
Testosterone is considered an essential absolute base to any cycle due to the fact that Testosterone is the body’s natural anabolic androgen. It also serves as an all-round excellent mass building compound that is suitable for bulking and strength gaining, and can also be utilized for the purpose of cutting and fat loss as well. In order to carry results further, other bodybuilding steroids are combined with (or “stacked” with) Testosterone. Some of the most popular anabolic steroids in this regard are compounds such as Dianabol (Methandrostenolone) , Winstrol (Stanozolol) , Nandrolone (Deca-Durabolin), and Trenbolone , among a few others. These Dianabol and Winstrol are two examples of oral bodybuilding steroids, though Winstrol does also come in an injectable format that is chemically identical to the oral, and thus even the injectable Winstrol can be ingested orally in order to garner the same effects as the tablet format. Oral anabolic steroids are generally regarded as bodybuilding steroids that are supplementary adjuncts to a solid base anabolic steroid cycle involving injectable bodybuilding steroids (namely, Testosterone).
