Steroid Profiles

The Steroid Profiles are required reading for anyone interested in understanding how steroids are used to increase muscle size and strength in bodybuilding and sports.. Included in this section are descriptions of anabolic steroids, human growth hormone and peptides, anti-estrogens, anti-prolactin drugs, reductase inhibitors and fat loss drugs.

Albuterol (Salbutamol)

One of the first articles I ever wrote which was widely circulated was about Clenbuterol. I wrote it partially to clear up some misconceptions about the drug, and partially because I got tired of answering the same questions over and over. Several years later, that article has been circulated on almost every anabolic steroid discussion [...]

Anabolicum Vister (Quinbolone)

Anabolicum Vister (quinbolone) is a prodrug of boldenone. It is the exact same molecule but with a cyclopentenyl ether modification at the 17beta hydroxy position. Unlike the ester modifications at the 17 position commonly used for injectable anabolic steroids, this modification provides enhanced oral bioavailability.

Anadrol (Oxymetholone)

Anadrol (oxymetholone) is perhaps only second to Dianabol (methandrostenolone) in importance as an oral anabolic in bodybuilding. This is due to its undoubted efficacy. Like Dianabol, Anadrol does not bind strongly to the androgen receptor (AR). Most of the anabolism it provides is therefore presumably via non-AR-mediated effects. When using either Anadrol or Dianabol at maximum [...]

Anadur (Nandrolone Hexylphenylpropionate)

Anadur (nandrolone hexylphenylpropionate) has a longer half life than Deca Durabolin (nandrolone decanoate). The claim that aromatization is less than with Deca Durabolin is unlikely to be correct. Because of the longer half life, for the same dose, there will be less drug in the blood during the first few weeks of use, thus creating this [...]

Anavar (Oxandrolone)

Anavar (oxandrolone), unlike most oral compounds is categorized as a Class I anabolic steroid, most efficiently stacked with Class II compounds such as Dianabol or Anadrol. It adds little if anything to high-dose use of Class I anabolic steroids such as trenbolone, or to high-dose testosterone, which is classified as having mixed activity. It can be [...]

Andriol (Testosterone Undecanoate)

Andriol, is a unique version of testosterone undecanoate developed by Organon. This version of testosterone is based in oil and is sealed in a capsule to be taken orally. According to the manufacturer, this method bypasses the liver and enters the body as a fat through the lymphatic system. In theory this seems quite interesting, [...]

Androgel (Transdermal Testosterone)

Androgel is the first testosterone gel approved by the FDA for hormone replacement therapy in men suffering from conditions involving low testosterone. Low testosterone, also known as hypogonadism, affects approximately four to five million American men. The condition is linked with diminished interest in sex, impotence, reduced muscle mass, decreased bone density and depressed mood and [...]

Arimidex (Anastrozole)

Arimidex (anastrozole) is the aromatase inhibitor of choice. The drug is appropriately used when using substantial amounts of aromatizing steroids, or when one is prone to gynecomastia and using moderate amounts of such steroids. Arimidex does not have the side effects of aminoglutethimide (Cytadren) and can achieve a high degree of estrogen blockade, much moreso [...]

Aromasin (Exemestane)

Aromasin (Exemestane) is one of those weird compounds that nobody really knows what to do with. What we generally hear about it makes it very uninteresting…It’s a third generation Aromatase Inhibitor (AI) just like Arimidex (Anastrozole) and Femera (Letrozole). Both of those two drugs are very efficient at stopping the conversion of androgens into estrogen, [...]

Avodart (Dutasteride)

Dutasteride, along with Finasteride is a 5-alpha-Reductase inhibitor which are a group of drugs with anti-androgenic properties which inhibit the conversion of testosterone into dihydrotestosterone (DHT). This is the same chemical found in Proscar and Propecia and is used in the treatment hyperplasia and androgenic alopecia. Because these drugs reduce levels of dihydrotestosterone (DHT) they [...]
