I'm using topical T, for two years now. It raised my T from 210 to 678 over past year, but then found Hemoglobin was higher than normal and endocrinologist was worried about stroke from concentrated red blood cells, so we lowered the dosage and I had a half liter of blood drawn. Then after finding my T was normal again, it plunged over three months to 120 and then to 210 while taking the same dosage. DHEA was also twice the normal range. Not sure what that means? Thoughts? I began applying the T directly to the genitals and it is back up to 680. Any others using topical T who apply it to the genitals instead of stomach or thighs? Thoughts? Hal
