On pills or patches, I only got above 100pmol/l three times in four years.
After many and quite heated discussions, I was switched to injections.
Pills get processed through the liver first, reducing their effectiveness and affecting blood clotting.
Patches need to be absorbed through the skin into the underlying layers of fat. I don't know if it was because they weren't penetrating my skin, poor product quality, or what, but they didn't work. I was wearing three patches at a time and changing weekly patches twice a week. No help.
Now that I am injecting directly into the fatty tissue, my levels have improved. I am less convinced by the "everybody's different" theme than by the "every medication is different " theme. That seems more prevalent, especially with generic products. Too much profit and not enough quality.
