I can't imagine any real benefit other then maybe a little more DHT, if that is what you are looking for.
At true TRT doses my hemoglobin and RBC count is well within range even with IM .
At 20mg Cypionate ED(140mg/wk) my hemoglobin is about 2 points higher than I want it to be regardless of phlebotomies. I was thinking of dropping Cypionate to 10mg/day and using 10mg/day Cream to see if there is any improvements with my total dosing being the same but from a 50-50 mix.
At 20mg/day what is your T level at?
