As I stated, the distinction is rather bogus. Injected T is least cost and 100% absorption. T gel$ and cream$ are typically 10% absorbed at best. If you sweat, shower or swim, it is lost. Transdermal T is highest T–>E2 potential, injected is least. If you are around young kids, you need to avoid any skin transfer of T!!
If your thyroid function is poor, you may not be able to absorb T gels or creams.
Compounding pharmacies are typically producing T creams.
