I will be very interested in how you do on this. I switched to creams and I am on 50mg/day. The assumption was that only 10% would be absorbed. My serum blood testing results showed my Testosterone levels were around 500, not good but not bad.
My doctor then wanted me to do the ZRT blood spot test because he said that the newest research shows that absorption is closer to 100%, but that serum blood samples do not reflect accurate levels when using a topical cream. The line of thought is that capillary blood collected via blood spot is more accurate for topical.
My results were over 7,000, which according to him is why my hematocrit and hemoglobin are elevated and why i initially felt good but now not so much because my receptors are down regulating. I encourage you and your doc to research it and see if you can make more sense of it than I can. Now I am in a quandry - do I dose according to the tried and true method, or does this blood spot test have merit?
