Total duration of use; the amount of time we supplement with testosterone is by no means set in stone, but we can confidently say anything less than 8 weeks will be a waste of time. A testosterone cycle that falls short of the 8 week mark, while it will produce gains, your body will not have been given the time to adapt to the gains, and they will largely be lost once use is discontinued. Of course, no matter how long a cycle is you are going to lose some gains; without the high influx of hormones, your body will not be able to maintain the progress. Even so, with proper cycle planning, a proper duration, adequate doses and a solid post cycle recovery plan you can protect a large portion of your gains. In any case, while 8 weeks of use is our minimal, most will find 12-16 weeks to be optimal for any testosterone cycle.
