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. 
After results showing I had low test I was referred to an endocrinologist who suggested I start testosterone replacement therapy, prescribing me pharma grade test e but at very infrequent doses and then trying to stop me altogether!! I decided to seek an alternative options and found Gear Phoenix. I was thrilled to see my test skyrocket after injections in the same way as the pharma grade test!
The test e I purchased was of the same quality as pharma grade, as I’m sure all of their other products are of the same standard and quality too!
Regardless of purpose, be it bulking or cutting most will find Trenbolone-Enanthate to be very effective in the 300mg-500mg per week range with 400mg per week generally being a very solid dose. Yes, you can use more but most will find doses that get much past 500mg per week to be a little less side-effect friendly, especially if they enter the 600mg per week range and almost assuredly if they surpass 700mg per week. Regardless of dosing most will find 8 weeks to be decently effective with 12 weeks of use generally being as far as you want to go. If your cycle is extended past 12 weeks it’s normally best to substitute another anabolic hormone in Tren’s place in-order to keep progress alive; yes, our body will adapt.
As for what you should stack Trenbolone-Enanthate with, simply pick whatever you want as this hormone stacks well with all anabolic steroids. However, it is highly recommended that testosterone be part of your stack as Trenbolone in any form will greatly suppress natural testosterone production. Many individuals also find supplementing with the T-3 hormone to be very useful as levels generally fall when Tren is present. Further, as responsible use is important a good Post Cycle Therapy (PCT) plan should occur after the cycle’s completion. In the case of Trenbolone-Enanthate, if your cycle ends with this steroid in play your PCT will not want to begin until at least 2 weeks have passed since your last injection.
