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 [38] 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. [39] [ 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. [39]

For the Testosterone Replacement Therapy candidate generally dosing will fall in the 100mg-200mg per week range and rarely surpassing this amount. However, as frequent injections are necessary most physicians will generally opt for larger ester forms, most commonly Testosterone-Cypionate so the patient only has to inject once per week.

For the performance enhancer the dosing will be much larger and the varying levels will be much wider too but he must necessarily inject frequently as discussed if he is going to maintain stability. Generally the minimal dose when supplementing for performance purposes will be 100mg every other day with 200mg every other day being as high as most will ever go. Yes, you an absolutely take more, there is no set in stone amount but understand such high-end doses can open up the doors to side-effects that you may have wished to remain shut. In elite level competitive sports, especially in elite level bodybuilding it is not uncommon to see doses surpass a 2,000mg per week range but this can be very harsh and there is simply no way such a dosing could ever be recommended in a responsible manner.

As with all cycles, as natural testosterone production will be suppressed, once use is discontinued and responsible use will include breaks Post Cycle Therapy (PCT) is a must in order to aid and speed up the recovery process. This is where Testosterone-Propionate has a bit of advantage over many other forms of testosterone; as a small ester that clears very quickly if your cycle ends with Testosterone-Propionate and there is no other long ester gear present in your system your PCT plan can start almost immediately. Remember, the sooner we start our PCT the better off we’ll be and such rapid PCT application cannot be accomplished with long ester based testosterone. If your cycle ends with Testosterone-Propionate you could reasonably wait 3 days before PCT therapy begins; if it ends with large ester gear you will need to wait approximately 2 weeks.

Fluticasone propionate is a highly selective agonist at the glucocorticoid receptor with negligible activity at androgen , estrogen , or mineralocorticoid receptors , thereby producing anti-inflammatory and vasoconstriction effects. It has been shown to have a wide range of inhibitory effects on multiple cell types (. mast cell , eosinophil , neutrophil , macrophages , and lymphocytes ) and mediators (. histamine , eicosanoids , leukotrienes , and cytokines ) involved in inflammation . Fluticasone propionate is stated to exert a topical effect on the lungs without significant systemic effects at usual doses, due to its low systemic bioavailability .
