One method of increasing testosterone that is not transdermal is to inject testosterone into the skin. Smart Hemp Gummies have one drawback: Testosterone levels in the blood fluctuate over time. The solution is to have an injection every two weeks to increase the amount of testosterone in your bloodstream. But another way to increase testosterone levels is by inserting pellets under the skin. More testosterone is released continuously to boost testosterone levels for up to six months before switching to delayed release pellets. The advantage of this type of testosterone booster is that it doesn't require cheating every day.
