Hi all. I’ve felt pretty low libido wise for a long time, put fat on easily in ladylike places, etc. So, I got some bloodwork done by my GP and my testosterone was 310. I went to an endo but first decided to see how tamoxifen would make me feel. 20mg/day for 6 days and then 9 days later got bloodwork done through my endo. This time came back differently:
K, so this bloodwork was done after 6 days of 20mg tamoxifen daily and a 9 day cessation of the tamoxifen before the bloodwork was done.
Testosterone total : 600 (went up, not bad)
Free testosterone : 1.1%, range: 1.5-3.2
Free testosterone: 66, range 52-280
cortisol: 19 ug/dL range: 8-19
igf-1 204 range: 155-432
prolactin: 8.9 range:3-18
t4, free: 1.50 range 0.82-1.77
LH: 5.6 range 1.7-8.6
FSH 1.2LOW range 1.5-12.4
Thyroxine 8.3 range 4.5-12.0
To my understanding tamoxifen has a half life of 7 days and its prodrug a halflife of 14 days. I don’t feel any better on the tamoxifen, but that could very well be from the side effects of it.
If anyone could put in their 2 pennies it’d be greatly appreciated. My endo wants to do bloodwork again in 2 months and I noticed on the bloodwork sheet he put down 257.2, hypogonadism.
