The crystal structures of six synthetic 2-oxa-steroids (A-ring lactone steroids) have been determined by single-crystal X-ray diffraction. The conformation and hydrogen bonding in these oxa-steroids is compared with packing motifs in the natural steroids and the anabolic agent, Anavar. O-H...O hydrogen bonding with lactone carbonyl O is the preferred arrangement in molecules with a C-OH group. The donor H atoms of A, B and D rings participate in C-H...O interactions with lactone carbonyl O and D-ring hydroxyl/ketone O acceptor atoms...

The purpose of this study was to determine the incidence of anabolic steroid use among competitive male and female bodybuilders in Kansas and Missouri. A profile was established for users and non-users of anabolic steroids. The results of this study indicated that more than half of the male bodybuilders (54%) were using steroids on a regular basis compared to 10 percent of the female competitors. The types of steroid used were investigated and revealed that on average, four different types of anabolic steroid were used during the year, with individual use ranging from one to fifteen different types; including Dianabol, Deca Durabolin, Anavar, Testosterone, Androl 50, Winstrol, Primobolan, Equipoise, Finaject, Parabolin, HCG, Primacetate, Enanthate, Halotestin, and Maxibolin, in order of the most to least frequently used...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase
