As we made mention of just a moment ago, Sustanon is a four-part testosterone combination comprised of multiple different esters – large and small. These four esters are: Testosterone Propionate, Testosterone Phenylpropionate, Testosterone Isocaproate, and Testosterone Decanoate. Each of these different esters combines together to produce both fast-acting and long-lasting testosterone results. This is a bit of an oddity in the world of TRT solutaions, but it has allowed Sustanon to become one of the dominant forces as far as testosterone supplementation is concerned. Of course, you can’t simply slap together these four testosterone esters and hope for the best. They need to be combined in a very precise manner to have the impact that you are looking for, and if even just one ester is out of balance you aren’t going to be able to take advantage of any of the benefits provided by Sustanon 250. To put together the exact formulation of Sustanon 250: 30 mg/mL of Testosterone Propionate 60 mg/mL of Testosterone Phenylpropionate 60 mg/mL of Testosterone Isocaproate 100 mg/mL of Testosterone Decanoate Anything else is a poor knockoff and will not produce anywhere near the quality or caliber of results you’re looking for from this TRT and performance-enhancing supplement. Should you come across products on the market that does not have the exact composition of testosterone esters we highlighted above, you should know that you are not looking at a legitimate Sustanon formulation? As far as acting as a pure testosterone compound is concerned, Sustanon is unique in that it allows its four esters to work together in concert with one another to produce fantastic results. It enjoys an anabolic and androgenic rating of a full 100 in both of these categories and is considered by many to be amongst the most versatile of all the steroid options on the planet today. Absolutely identical in every way to the testosterone produced by your body on a daily basis, you’ll be able to enjoy all of the improved confidence, sexual endurance, and decisiveness that elevated levels of testosterone inevitably bring to the table.
