Testosterone patches can be either scrotal or non-scrotal and are also known to be effective in increasing the body’s T-levels. The downside to using this however is that it tends to irritate the skin. Testosterone gels are known to be significantly absorbed by the skin and have a near-instant absorption rate which lasts throughout the day. And there’s also the buccal testosterone which is known to produce even better results than the patches when applied to the gums. The side effects of that however often include bitter taste in the mouth and some irritation to the gums.
