Supertest 450 is an injectable drug that contains five testosterone esters. It contains testosterone with an ester and, contrary to popular belief, the design of this injectable will support or increase testosterone release for a long time.
Among bodybuilders, Supertest 450 is known to be an extremely powerful mass agent. Supertest 450 is often classified as the most powerful injectable steroid available, resulting in a rapid increase in muscle mass and strength. This is due to the very long-acting Supertest 450, as the oil-based steroid will start to flow into the bloodstream almost immediately after an injection. Unlike fast esters that take several days for blood levels to reach maximum therapeutic levels, with Supertest 450 it's a matter of a few weeks. Clearly, the anabolic effect of this Testosterone will be much more than we would expect with a water-based preparation (unesterified). When an ester is present, its weight is included in the total milligram of the preparation. Regarding SP Enanthate, 100 mg of this compound is equivalent to only 72 mg of pure testosterone. So, the bodybuilder who uses 400 mg of SP Enanthate weekly gets about 288 mg of testosterone in his body every week. This is a large increase over the average endogenous testosterone level of men, which is in the range of 2.5 to 11 mg/day. But the general point is that during a Supertest 450 cycle we will often notice a much more dramatic testosterone intake on average than is commonly used with water.
