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  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.  [ 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 .  : 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. 
This product coverts to the steroid boldenone in the body. Boldenone isn’t a particularly strong androgen, but it does have some things that make it good for a stacking item. 1,4 Andro can convert to estrogen, but it seems to do so at a slower rate than other items. It should also have a reduced effect on the hairline, so it is a pretty safe product in general. It is a decent stacker since it increases appetite and should help with endurance. It can also have a joint repairing effect, which is a good side effect. I have never heard of anyone gaining serious mass from Androstadienedione, even at 600mg per day, but it is a decent product for stacking. As you can see, it is also pretty safe, being about half as androgenic as testosterone with all of the anabolic effects.
Where Hi-Tech changes the game here is with their Cyclosome technology, which vastly improves bioavailability, as discussed below. For this reason, the base dose of Equibolin is only two tablets per day, with a maximum of four tablets for experienced users. This is all discussed lower down.
