steroids, class of lipids having a particular molecular ring structure called the cyclopentanoperhydro-phenanthrene ring system. Steroids differ from one another in the structure of various side chains and additional rings. Steroids are common in both plants and animals. In humans, steroids are secreted by the ovaries and testes, the adrenal cortex (see adrenal gland ), and the placenta.

The range of steroids is diverse, including several forms of vitamin D, digitalis, sterols (., cholesterol ), and the bile acids. Many steroids are biologically active hormones that control a number of the body's metabolic processes. This group includes the male sex hormone testosterone and the female sex hormones estrogen and progesterone . The steroid hormones of the adrenal cortex include glucocorticoids such as cortisone and cortisol (see also corticosteroid drug ) and mineralocorticoids such as aldosterone .

Natural or synthetic steroids are used in oral contraceptives and in the treatment of arthritis , Addison's disease , and certain skin ailments. Side effects, related to dosage and length of treatment, can be serious and include high blood pressure, edema, unwanted hair growth, and menstrual cycle disruption. Anabolic steroids , male hormones given to build up strength in seriously ill patients, have been abused by bodybuilders and athletes in an attempt to increase muscle mass and strength.

Best described in the documentary “Bigger, Stronger, Faster*,” steroids will only amplify personality characteristics that the individual already has. The only studies to have come from steroids are those performed on rats. The difference between humans and rats? We have a better capacity to control aggression. Caffeine and other stimulants have also been included within literature as stimulants that lead to higher levels of aggression, but should coffee be blamed for all outbursts by coffee drinkers? It also has been suggested that estrogen in fact is to blame for increased levels of aggression. Testosterone on the contrary makes males feel positive and motivated.

We've listed the commonly used anabolic steroids, but the next question is what the best of the best are; of the 22 forms, which ones are the best steroids of all? In many ways, this is a very hard question to answer, as your individual goals and desires will dictate quite a bit, but we will still provide some answers. Without question, if one was to be listed as the absolute best of all it would go to Trenbolone-Acetate. Any Trenbolone form will find itself at the top of the pack, but Fina simply edges out the rest, and for good reasons. There is no steroid as versatile as Trenbolone, no steroid that can provide such dramatic changes in any direction from bulking to cutting. Beyond Trenbolone, the next best steroids included the numerous testosterone forms, but if we include the importance of a steroid to the human body as well as its tolerable level testosterone wins hands down. Like Trenbolone, testosterone is very versatile, it will not provide the conditioning of Trenbolone, but it is so well-tolerated and so essential to our health it always finds itself at the top of the list. At any rate, we have again listed some steroids below, this time they have been broken down into bulking and cutting categories. We have taken the 22 most commonly used steroids, the best steroids of all and left you with the top five for bulking and the top five for cutting. Some may disagree with our choices, but each choice was made considering the hormones versatility, means to promote the specific function of the class, its milligram potency and on some level its tolerable nature. We have for your convenience also listed the best steroids for women in the final list below:

Steroid isolation , depending on context, is the isolation of chemical matter required for chemical structure elucidation, derivitzation or degradation chemistry, biological testing, and other research needs (generally milligrams to grams, but often more [37] or the isolation of "analytical quantities" of the substance of interest (where the focus is on identifying and quantifying the substance (for example, in biological tissue or fluid). The amount isolated depends on the analytical method, but is generally less than one microgram. [38] [ page needed ] The methods of isolation to achieve the two scales of product are distinct, but include extraction , precipitation, adsorption , chromatography , and crystallization . In both cases, the isolated substance is purified to chemical homogeneity; combined separation and analytical methods, such as LC-MS , are chosen to be "orthogonal"—achieving their separations based on distinct modes of interaction between substance and isolating matrix—to detect a single species in the pure sample. Structure determination refers to the methods to determine the chemical structure of an isolated pure steroid, using an evolving array of chemical and physical methods which have included NMR and small-molecule crystallography . [2] :10–19 Methods of analysis overlap both of the above areas, emphasizing analytical methods to determining if a steroid is present in a mixture and determining its quantity. [38]
