Just prescribed this by my uro for low T. I was previously on a laundry list of SSRI'S and anti anxiety meds. My uro told me it would be probably a couple shots until I really feel the results. The good thing is I felt better than I have in years a single day after the 1.5cc inj. in the hip. Zero depression, Zero anxiety. Is 8 days really the half life or does it depend on one's metabolism? I took the injection on Thursday and had the best weekend. Loads of energy, no mood swings, I felt like a rockstar. I feel a little "down" today and just trying to discern if my body is metabolizing or if it's in my head? Bloodwork will be done in a month. Uro said he is concerned more with how I feel. My wife is a rep in big pharma, so I know that some of the uro reps will have some very good info. Do any reps have some data on how fast Test. Cyp. is metabolized? Serum was 149 Free was 6.6 36/m I don't understand why docs don't check this before they throw you on 10 different head meds. Thanks for any info.
