Halotestin is the Upjohn brand name for the steroid fluoxymesterone. Structurally fluoxymesterone is a derivative of testosterone, differing from our base androgen by three structural alterations (specifically l7alpha-methyl, 11 beta-hydroxy and 9-fluoro group additions). The result is a potent oral steroid that exhibits extremely strong androgenic properties. This has a lot to due with the fact that it is derived from testosterone, and as such shares important similarities to this hormone. Most importantly, like testosterone, Halotestin appears to be a good substrate for the 5-alpha reductase enzyme. This is evidenced by the fact that a large number of its metabolites are found to be 5-alpha reduced androgens, which coupled with its outward androgenic nature, suggests it is converting to a much more active steroid in androgen responsive target tissues such as the skin, scalp and prostate.

Femara (generic name is letrozole) is a new drug developed for the treatment of advanced breast cancer in women. Femara is the second in a new class of third-generation selective oral aromatase inhibitors.. It acts by blocking the enzyme aromatase, subsequently blocking the production of estrogen. Since many forms of breast cancer cells are stimulated by estrogen, it is hoped that by reducing amounts of estrogen in the body the progression of such a disease can be halted. This is the basic premise behind Nolvadex, except this drug blocks the action and not production of estrogen. The effects of Femara can be quite dramatic to say the least. A daily dose of one tablet (2.5 mg) can produce estrogen suppression greater than 80 % in treated patients. With the powerful effect this drug has on hormone levels, it is only to be used (clinically) by post-menopausal women whose disease has progressed following treatment with Nolvadex. Side effects like hot flushes and hair thinning can be present, and would no doubt be much more severe in pre-menopausal patients.
EquipoiseR is the popular brand name for the veterinary injectable steroid boldenone undecylenate. It is a derivative of testosterone, which exhibits strong anabolic and moderately androgenic properties. The undecylenate ester greatly extends the activity of the drug (the undecylenate ester is only one carbon atom longer than decanoate), so that clinically injections would need to be repeated every three or four weeks. In the veterinary feild Equipoise is most commonly used on horses, exhibiting a pronounced effect on lean bodyweight, appetite and general disposition of the animal. As with all steroids, this compound shows a marked ability for increasing red blood cell production. In recent years this compound has become a favorite among athletes. Many consider it an ideal replacement to Deca-Durabolin.
Ephedrine is a stimulant drug, belonging to a group of medicines known as sympathomimetics. Specifically it is both an alpha and beta adrenergenic agonist (you may remember Clenbuterol is a selective beta-2 agonist). In addition, ephedrine enhances the release of norepinephrine, a strong endogenous alpha agonist. The action of this compound is notably similar to that of the body’s primary adrenergic hormone epinephrine (adrenaline), which also exhibits action toward both alpha and beta receptors. When administered, ephedrine will notably increase the activity of the central nervous system, as well as have a stimulatory effect on other target cells. This will produce a number of effects beneficial to the athlete. For starters, the user’s body temperature should rise slightly as more free fatty acids are produced from the breakdown of triglycerides in adipose tissue (stimulating the metabolism). This should help the user shed subcutaneous body fat stores, enhancing the look of definition in the physique. The anabolic effectiveness of steroids may also be increased with this substance (mildly), as the metabolic rate is a measure of fat, protein and carbohydrate conversion by the body. An enhanced metabolic state could clearly hasten the deposit of new muscle mass.
Dianabol is the old Ciba brand name for the oral steroid methandrostenolone. It is a derivative of testosterone, exhibiting strong anabolic and moderate androgenic properties. This compound was first made available in 1960, and it quickly became the most favored and widely used anabolic steroid in all forms of athletics. This is likely due to the fact that it is both easy to use and extremely effective. In the U.S. Dianabol production had meteoric history, exploding for quite some time, then quickly dropping out of sight. Many were nervous in the late 80’s when the last of the U.S. generics were removed from pharmacy shelves, the medical community finding no legitimate use for the drug anymore. But the fact that Dianabol has been off the U.S. market for over 10 years now has not cut its popularity. It remains the most commonly used black market oral steroid in the U.S. As long as there are countries manufacturing this steroid, it will probably remain so.
Deca-Durabolin is the Organon brand name for the injectable steroid nandrolone decanoate. This compound came around early in the wave of commercial steroid development, first being made available as a prescription medication in 1962.
Cytomel is the popularly recognized brand name for the drug liothyronine sodium. This is not an anabolic steroid but a thyroid hormone. It is used medically to treat cases of thyroid insufficiency, obesity, certain metabolic disorders and fatigue. Specifically this drug is a pharmaceutical preparation of the natural thyroid hormone triiodothyronine (T-3). When administered, Cytomel increases the patient’s metabolism. The result is an increased rate of cellular activity (noted by a more rapid utilization of carbohydrates, fats and proteins). Bodybuilders are particularly attracted to this drug for its ability to burn off body excess fat. Most often utilized during contest preparation, one can greatly decrease the amount of stored fat without being forced to severely restrict calories. To this end Cytomel is commonly used in conjunction with Clenbuterol and can produce extremely dramatic results. This combination has become very popular in recent years, no doubt responsible for many “ripped” on-stage physiques. It is also noted by many that when thyroid hormones are taken in conjunction with steroids, an increased anabolic effect can be seen (noticeably greater than if the steroids are used alone). This is likely due to faster utilization of proteins by the body, increasing the rate for new muscle accumulation.
Clomid is the commonly referenced brand name for the drug clomiphene citrate. It is not an anabolic steroid, but a prescription drug generally prescribed to women as a fertility aid. This is due to the fact that clomiphene citrate shows a pronounced ability to stimulate ovulation. This is accomplished by blocking/minimizing the effects of estrogen in the body. To be more specific Clomid is chemically a synthetic estrogen with both agonist/antagonist properties, and is very similar in structure and action to Nolvadex. In certain target tissues it can block the ability of estrogen to bind with its corresponding receptor. Its clinical use is therefore to oppose the negative feedback of estrogens on the hypothalamic-pituitary-ovarian axis, which enhances the release of LH and FSH. This of course can help to induce ovulation.
Clenbuterol is a widely used bronchodilator in many parts of the world. The drug is most often prepared in 20mcg tablets, but it is also available in syrup and injectable form. Clenbuterol belongs to a broad group of drugs knows as sympathomimetics. These drugs affect that sympathetic nervous system in a wide number of ways, largely mediated by the distribution of adrenoceptors. There are actually nine different types of these receptors in the body, which are classified as either alpha or beta and further subcategorized by type number. Depending on the specific affinities of these agents for the various receptors, they can potentially be used in the treatment of conditions such as asthma, hypertension, cardiovascular shock, arrhythmias, migraine headaches and anaphylactic shock. The text Goodman and Gillman’s The Pharmacological Basis of Therapeutics Edition does a good job of describing the diverse nature in which these drugs affect the body: 
ArimidexR (generic name is anastrozole) is a newer drug developed for the treatment of advanced breast cancer in women. It is manufactured by Zenica Pharmaceuticals and was approved for use in the United States at the end of December 1995. Specifically, Arimidex is the first in a new class of third-generation selective oral aromatase inhibitors.. It acts by blocking the enzyme aromatase, subsequently blocking the production of estrogen. Since many forms of breast cancer cells are stimulated by estrogen, it is hoped that by reducing amounts of estrogen in the body the progression of such a disease can be halted. This is the basic premise behind Nolvadex, except this drug blocks the action and not production of estrogen. The effects of Arimidex can be quite dramatic to say the least. A daily dose of one tablet (1 mg) can produce estrogen suppression greater than 80 % in treated patients. With the powerful effect this drug has on hormone levels, it is only to be used (clinically) by post-menopausal women whose disease has progressed following treatment with Nolvadex (tamoxifen citrate). Side effects like hot flushes and hair thinning can be present, and would no doubt be much more severe in pre-menopausal patients.
