When concluding a cycle, some steroid users also follow a practice of first slowly reducing their dosages (tapering). This tapering may proceed for a 3-4 week period, and will involve an even stepping down of the dose each week until the point of drug discontinuance. It is unknown, however, if such tapering offers any tangible value. This practice has never been evaluated in a clinical setting, and is not widely recommended with steroid medications as it is with some other drugs such as thyroid hormones or antidepressants. Virtually every high-dose AAS administration study can also be found to end at the maximum dosage, with no time allotted to tapering. One flaw in the logic of using a tapering program is that they are ostensibly designed to aid hormone recovery. Recovery is not possible, however, while supraphysiological levels of androgens are present, and such levels are usually found during all weeks of a normal (nonmedical) steroid taper. Individuals remain cautioned that dosage tapering is not a proven way to reduce post- cycle muscle catabolism.
