Depending on the number and character of their functional groups, steroid molecules may show diverse reactivities. Moreover, the reactivity of a functional group varies according to its location within the molecule (for example, esters are formed readily by 3-OH groups but only with difficulty by the 11β-OH group). An important property of steroids is polarity —., their solubility in oxygen-containing solvents (., water and alcohols ) rather than hydrocarbon solvents (., hexane and benzene ). Hydroxyl, ketonic, or ionizable (capable of dissociating to form electrically charged particles) groups in a steroid molecule increase its polarity to an extent that is strongly influenced by the spatial arrangement of the atoms within the molecule.

“Now everyone is starting off at a different level so depending on your last cycle adjustments can be made to fit each individual,” according to Piana. “It can be scaled down or up hopefully people can handle this part on their own. For the more advanced that are doing much higher doses of GH my reasoning is anything higher than iu a day will cause the intestines to grow and eventually you will have a growth gut also same goes for using insulin but everyone is free to add on whatever they choose. GH and insulin will put on more size than anything but in my opinion it will ruin the physique!”

Judging Rounds - In the universally accepted and applied IFBB system of judging, bodybuilders are evaluated in three distinctly different rounds of judging, plus a final pose down round for only the top five competitors after the first three rounds have been adjudicated. In Round One, the competitors are viewed in groups and individually in seven well-defined compulsory poses; in Round Two, they are viewed semi-relaxed from the front, both sides, and back; and in Round Three, they perform their own uniquely personal free-posing routines to their own choice of music. Overall, this use of three rounds of judging and a pose down round results in a very fair choice of the final winners of a bodybuilding champion-ship.

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 [39] 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. [40] [ 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. [40]
