Arimidex — anastrozole

Anastrozole is an anti-estrogenic drug developed for the treatment of advanced breast cancer in women. Specifically, this agent is the first in a newer class of third-generation selective oral aromatase inhibitors. It acts by blocking the enzyme aromatase, subsequently blocking the production of estrogen in the body. Since many forms of breast cancer cells are

Aranesp — darbepoetin alfa

Darbepoetin alfa is a synthetic derivative of the human erythropoietin protein. It also has the same pharmacological action as recombinant human erythropoietin (epoetin alfa). In the body, erythropoietin is normally released by the kidneys in response to hypoxia (low blood oxygen levels). This in turn triggers bone marrow to increase red blood cell production. As

Arachidonic Acid

Arachidonic acid is an omega-6 essential fatty acid that serves as the principle building block for the synthesis of dienolic prostaglandins (such as PGE2 and PGF2a). These prostaglandins are integral to protein turnover and muscle accumulation, and have such important activities as increasing blood flow to the muscles (pumps), increasing local IGF-1 and insulin sensitivity

Andronaq — testosterone suspension

Testosterone suspension is an injectable preparation containing testosterone (no ester), usually in a water base. Among bodybuilders, “suspension” is known to be an extremely potent mass agent. It is often said to be the most powerful injectable steroid available, producing very rapid gains in muscle mass and strength. This is largely due to the very

Andromar Retard — testosterone cyclohexylpropionate

Testosterone cyclohexylpropionate, or CHP for short, is a slow acting injectable ester of the primary male androgen testosterone. The cyclohexylpropionate ester is very similar in structure to the cypionate (cyclopentylpropionate) ester, different only by the inclusion of a cyclohexane ring (6 carbon atoms) instead of cyclopentane ring (5 carbon atoms). Given the close similarity of

AndroGel — testosterone

AndroGel is a transdermal hydroalcoholic testosterone gel that contains a 1% concentration of testosterone by weight. It was originally released in 2.5 gram and 5-gram sachets, equating to a total per-application testosterone dose of 25 mg and 50 mg respectively. The AndroGel prescribing information states that the product has a transdermal bioavailability of approximately 10%.

Androderm — testosterone

Androderm is a testosterone delivery system that utilizes an adhesive “patch” to deliver the hormone transdermally. The testosterone itself is dissolved in an alcoholic gel similar to AndroGel, except here the gel is contained in a protected external drug reservoir. This design provides approximately double the hormone bioavailability of AndroGel, and also severely limits the

Andriol — testosterone undecanoate

Andriol is an oral testosterone preparation that contains 40 mg of testosterone undecanoate (in an oil base) in a soft gelatin capsule. This drug is very different than most oral anabolic steroids, which are usually c-17 alpha alkylated to survive first pass metabolism through the liver. Instead, esterification and suspension in oil allows the testosterone

Andractim — dihydrotestosterone

Andractim is a prescription steroid preparation that contains the potent androgenic steroid dihydrotestosterone. This product comes in the form of a transdermal gel, typically containing 2.5% dihydrotestosterone by weight in an 80gram tube. As with Androgel, roughly 10% of the active steroid will make it into circulation with each application.This would equate to 80 doses

Andarine — S4, GTx-007

Andarine is a second generation Selective Androgen Receptor Modulator (SARM). SARMs are all closely related to anabolic steroids in activity.They bind the same cellular androgen receptor (AR), and impart similar anabolic effects. However, like andarine, most are non-steroidal in structure. They are also highly selective in their receptor interactions (hence the name). These drugs are
