Testosterone should be used at a minimum of 10 weeks if you want to obtain tangible results from your cycle. It takes a few weeks for the beneficial effects to “kick in” and the best gains you’ll make are typically towards the end of your cycle. It is more common to run a cycle of Test for 12 weeks, though this can be extended to 14-16 weeks with relatively little issue. Just know that the longer your natural production of testosterone is suppressed, the harder it will be to restore it during post-cycle therapy and afterwards. For this reason, a cycle of Test shouldn’t extend beyond 20 weeks tops and it would be safer overall to run it in 12-16 week durations.
The key to masculinity and vitality is the human growth hormone that separates the boys from the men. It plays a vital role in the creation of muscle mass and strong bones. It contributes to deep voice and even sex drive. Low testosterone in men is known as hypogonadism. As a product of a modern world made for convenience the male body does not go through nearly as much rigorous activity. The lack of daily exercise contributes to the decrease in male testosterone. It can hit as early as the mid 20s and steadily decrease each subsequent year.
